They will assist you when using your S5-135U/155U programmable controller. At the start of this manual you will find the "Safety-Related Guidelines" and the "ESD Guidelines." You must observe these to the letter and follow them during the entire time you are working with the S5-135U/155U PLC. If your PLC requires repair, you must observe the Repair Guidelines in Section 4.1.4. Chapter 3 contains the Installation Guidelines with information on interference-free installation of the S5-135U/155U PLC. Which of the remaining chapters of this manual you may require when working with your PLC will depend on the extent of your automation task and on the configuration of your PLC. For a basic configuration in single-processor operation without expansion units, you will need the following chapters: Chapter 4 describes the central controller (CC) in Section 4.1. The technical features, installation, startup and maintenance of the CC are described here. Section 4.3 describes the power supply units. You will find a separate description of the 6ES5 955-3NA12 power supply unit in Section 4.5. Both sections describe the installation and startup as well as the necessary maintenance on the power supply units. The 24 V/4 A load power supply is described in Section 4.4. Chapter 5 contains the instructions for the individual CPUs. The technical features, installation and startup of the individual CPUs are described here. The various methods of operating the CPUs are also described, as are the CPU statuses where they can be directly indicated by the LEDs on the module. If you use memory submodules or memory cards (CPU 948), you can look up the necessary information in Sections 5.7 to 5.9. Chapter 8 and Chapter 9 describe the digital and analog I/O modules. The installation, wiring and operation of these modules are described here. Individual I/O modules exhibit specific features which are discussed in separate chapters. To configure your PLC with expansion units (EUs) you will need the following chapters: Chapter 2 shows how you can configure a PLC with expansion units in a centralized or distributed arrangement. Chapter 4, Section 4.2, describes the EU 183U, EU 184U, EU 185U and EU 187U. Those EUs which operate with their own power supply unit are described in Section 4.3. Chapter 7 describes the interface modules (IMs) which serve for data communication between central controllers and expansion units. To operate two or more CPUs in multiprocessor mode in your PLC, you will need Chapter 6. Chapter 6 describes multiprocessor operation. This chapter contains all the measures you must take for startup of the PLC in multiprocessor operation. Sections 6.5 and 6.6 describe the 923C and 923A coordinators. 1-2 System Manual C79000-G8576-C199-07 Notes on Using this Manual and on the CE Symbol Chapter 11 lists the connector assignments of the individual modules and subracks.

Therefore, there is no declaration of conformity for SIMATIC as regards the EC Directive 89/392/EEC on machines. EC Directive 89/392/EEC on Machines The EC Directive 89/392/EEC on machines controls machine requirements. Here, a machine is understood to be the entire sum of devices or parts involved (see also EN 292-1, paragraph 3.1). SIMATIC is part of the electrical equipment for a machine and must therefore be included in the procedure for checking conformity by the machine manufacturer. Electrical Equipment for Machines to EN 60204 EN 60204-1 Para. 4 The EN 60204-1 standard (machine safety, general requirements for the electrical equipment for machines) applies to the electrical equipment for machines. The following table should help you with the declaration of conformity and shows which criteria apply to EN 60204-1 (as at June 1993) for SIMATIC. Subject/Criterion General requirements Remarks Requirements are fulfilled if the machines are assembled/installed according to the installation guidelines. See also the explanations on the previous pages. Para. 11.2 Digital I/O interfaces Requirements are fulfilled. Para. 12.3 Programmable equipment Requirements are fulfilled if the machines are installed in lockable cabinets to protect them from memory modifications by unauthorized persons. Para. 20.4 Voltage tests Requirements are fulfilled. 1-6 System Manual C79000-G8576-C199-07 Notes on Using this Manual and on the CE Symbol Safety Notes Risks Involved in the Use of So-Called SIMATIC-Compatible Modules of Non-Siemens Manufacture "The manufacturer of a product (SIMATIC in this case) is under the general obligation to give warning of possible risks attached to his product. This obligation has been extended in recent court rulings to include parts supplied by other vendors. Accordingly, the manufacturer is obliged to observe and recognize such hazards as may arise when a product is combined with products of other manufacture. For this reason, we feel obliged to warn our customers who use SIMATIC products not to install so-called SIMATIC-compatible modules of other manufacture in the form of replacement or add-on modules in SIMATIC systems. Our products undergo a strict quality assurance procedure. We have no knowledge as to whether outside manufacturers of so-called SIMATIC-compatible modules have any quality assurance at all or one that is nearly equivalent to ours. These so-called SIMATIC-compatible modules are not marketed in agreement with Siemens; we have never recommended the use of so-called SIMATIC-compatible modules of other manufacture. The advertising of these other manufacturers for so-called SIMATIC-compatible modules wrongly creates the impression that the subject advertised in periodicals, catalogs, or at exhibitions had been agreed with us. Where so-called SIMATIC-compatible modules of non-Siemens manufacture are combined with our SIMATIC automation systems, we have a case of our product being used contrary to recommendations. Because of the variety of applications of our SIMATIC automation systems and the large number of these products marketed worldwide, we cannot give a concrete description specifically analyzing the hazards created by these so-called SIMATIC-compatible modules. It is beyond the manufacturer's capabilities to have all these so-called SIMATIC-compatible modules checked for their effect on our SIMATIC products. If the use of so-called SIMATIC-compatible modules leads to defects in a SIMATIC automation system, no warranty for such systems will be given by Siemens. In the event of product liability damage due to the use of so-called SIMATIC-compatible modules, Siemens are not liable since we took timely action in warning users of the potential hazards involved in so-called SIMATIC-compatible modules."

You will find a description of the types of communication between a central controller and the expansion units, and an overview of the interface modules required for the different types of communication. Chapter Overview System Manual C79000-G8576-C199-07 Section Contents Page 2.1 Application 2-2 2.2 Centralized and Distributed Configuration 2-3 2.3 Examples 2-6 2-1 Centralized and Distributed Configuration of a Programmable Controller 2.1 Application The S5-135U/155U programmable controllers comprise a central controller (CC) and, if required, one or more expansion units (EUs). You need EUs when there are insufficient slots in the CC for the modules to be used. Various interface modules (IMs) are available for communication between the CC and the EUs and between the EUs. It is therefore possible to install an EU or EUs in the immediate vicinity of the CC (centralized configuration) or at some distance (distributed configuration). A combination of both types of configuration is also possible by connecting additional EUs in a centralized configuration with a distributed EU (see Figure 2-5). This is clarified on the following pages. 2-2 System Manual C79000-G8576-C199-07 Centralized and Distributed Configuration of a Programmable Controller 2.2 Centralized and Distributed Configuration You can install a PLC in centralized or distributed configuration according to your application.

Electromagnetic compatibility (EMC) is understood to mean the capability of electrical equipment to operate correctly in a defined electromagnetic environment, without being affected by the environment and without affecting the environment to an unacceptable degree. All SIMATIC S5 products have been developed for applications in harsh industrial environments and meet high requirements for EMC. Before installing the control system, however, you should still carry out EMC planning and involve possible interference sources in the assessment. The following chapter describes The various paths over which interference can be picked up in the PLC, Typical interference sources and their coupling mechanisms, Basic rules for ensuring EMC. 3.1.1 Overview of Possible Types of Interference Electromagnetic interference can be picked up over different paths by the programmable controller: Fields SINEC Bus System Programmable Controller Power Supply Figure 3-1 3-2 I/O Signal Lines Protective Conductor Electromagnetic Interference with Programmable Controllers System Manual C79000-G8576-C199-07 Installation Guidelines Depending on the propagation medium (conducted or non-conducted interference) and distance from the source, interference can be picked up by the programmable controller via different coupling mechanisms. A distinction is made between the following: Direct coupling Capacitive coupling Inductive coupling Radiated interference System Manual C79000-G8576-C199-07 3-3 Installation Guidelines Coupling Mechanisms and Typical Interference Sources at a Glance The following table shows the four different coupling mechanisms, their causes, and possible interference sources.

When installing the control system, therefore, observe the following five basic rules. When installing the programmable controllers, provide large-area good quality grounding of the inactive metal parts (see Section 3.2). Make a large-area low-impedance interconnection of all inactive metal parts. For screw connections on painted and anodized metal parts, either use special contact washers or remove the insulating protective layers. If possible, do not use aluminum parts. Aluminum oxidizes easily and is therefore less suitable for grounding. Make a central connection between the chassis ground and the ground/protective ground conductor system. Ensure proper routing of lines when wiring (see Sections 3.3.1 and 3.3.2). Arrange the cabling in line groups. (AC power cable, power supply lines, signal lines, data lines) Always install AC power cables and signal or data lines in separate ducts or bunches. Route the signal and data lines as closely as possible to grounded surfaces such as cabinet elements, metal bars and cabinet panels. Ensure that cable shields are properly secured (see Section 3.3.3). Data lines must be shielded. The shield should be connected at both ends. Analog lines must be shielded. For the transfer of signals with low amplitudes, it may be advisable to connect the shield at only one end. Provide the line shields with a large-area connection to a shield/protective conductor bar immediately after the cabinet inlet, and secure the shields with cable clamps. Route the grounded shield as far as the module without interruption, but do not connect the shield there again. Ensure that the shield/protective ground bar has a low-impedance connection to the cabinet. Use metal or metallized connector cases for shielded data lines. 3-6 System Manual C79000-G8576-C199-07 Installation Guidelines Employ special EMC measures for particular applications (see Section 3.3.4). Fit quenching elements to all inductances which are not controlled by SIMATIC S5 modules. Use incandescent bulbs for illuminating cabinets, and avoid fluorescent lamps. Create a standard reference potential; ground all electrical apparatus if possible (see Sections 3.4 and 3.5). Use specific grounding measures. Grounding of the control system is a protective and functional measure. System parts and cabinets with central controllers and expansion units should be connected to the ground/protective conductor system in star configuration. This serves to avoid the creation of ground loops. In the case of potential differences between system parts and cabinets, install equipotential bonding conductors of sufficient rating. System Manual C79000-G8576-C199-07 3-7 Installation Guidelines 3.2 Installation of Programmable Controllers for EMC Measures for suppressing interference voltages are often applied only when the control system is already operational and proper reception of a useful signal is impaired. The reason for such interference is usually inadequate reference potentials caused by mistakes in equipment assembly. The following sections describe: Basic rules for grounding the inactive metal parts Examples of cabinet assembly for EMC Example of rack and wall mounting for EMC 3.2.1 Basic Rules for Assembling and Grounding the Inactive Metal Parts Ensure wide-area chassis grounding of the inactive metal parts when mounting the equipment. Properly implemented grounding creates a uniform reference potential for the control system, and reduces the effects of picked-up interference. Chassis grounding is understood to mean the electrical connection of all inactive parts. The entirety of all interconnected inactive parts is the chassis ground. Inactive parts are conductive parts which are electrically isolated from active parts by basic insulation, and can only develop a voltage in the event of a fault. The chassis ground must not develop a dangerous touch voltage, even in the event of a fault. The ground must therefore be connected to the protective ground conductor. To prevent ground loops, locally separated ground elements such as cabinets, structural and machine parts, must always be connected to the protective ground system in star configuration. Ensure the following when chassis grounding: Connect the inactive metal parts with the same degree of care as the active parts. Ensure low-impedance metal-to-metal connections, e.g. with large-area good quality contact. When you are incorporating painted or anodized metal parts in the grounding, these insulating protective layers must be penetrated. Use special contact washers or remove the insulating layer. Protect the connection points from corrosion, e.g. with grease. Movable grounded parts such as cabinet doors must be connected via flexible grounding strips. The grounding strips should be short and have a large surface because the surface is decisive in providing a path to ground for high-frequency interference. 3-8 System Manual C79000-G8576-C199-07 Installation Guidelines 3.2.2 Example of Cabinet Assembly for EMC The example of cabinet assembly in the figure shows the various measures, the grounding of inactive metal parts and the connection of shielded cables. This example applies only to grounded operation. Follow the points numbered in the figure during assembly. 1 2 3 4 5 6 7 8 Figure 3-2 Example of Cabinet Assembly for EMC System Manual C79000-G8576-C199-07 3-9 Installation Guidelines Grounding strips If there are no large-area metal-to-metal connections, you must connect inactive metal parts such as cabinet doors and supports with grounding strips. These should be short and have a large surface. Cabinet members The cabinet members should have a large-area connection to the cabinet housing (metal-to-metal connection). Mounting bracket for subrack There must be a large-area metal-to-metal connection between cabinet member and mounting bracket. Signal lines In the case of shielded signal lines and data lines, the shield must be secured to the protective conductor bar or an additionally fitted shield bar using large-area cable clamps. Cable clamp The cable clamp must enclose and make contact with the shield braid over a large area. Shield bar This bar must have a large-area connection to the cabinet members (metal-to-metal connection). It serves for grounding the cable shields. Protective conductor bar The protective conductor bar must have a large-area connection to the cabinet members (metal-to-metal connection). The protective conductor bar must be connected to the protective conductor system via an external conductor (at least 10 mm2). This is essential for providing a reliable path to ground for fault currents and interference currents. Conductor to the protective conductor system (ground point) The conductor must have a large-area connection to the protective conductor system (ground point). 3-10 System Manual C79000-G8576-C199-07 Installation Guidelines 3.2.3 Example of Rack and Wall Mounting for EMC To operate your control system in a low-interference environment whilst observing the permissible ambient conditions (see "Technical Specifications"), you can mount the programmable controllers on racks or directly on walls. Picked-up interference should be given a path to large metal surfaces. You should therefore secure standard sectional rails, shield and protective conductor bars to metal structural elements. For wall mounting in particular, installation on reference potential surfaces made of sheet steel has proved advantageous. When installing shielded cables, provide a shield bar for connecting the cable shields. The shield bar can also be the protective conductor bar. Ensure the following for rack and wall mounting: Suitable contacting aids should be used on painted and anodized metal parts. Use special contact washers or remove the insulating protective layers.

The purpose of cable routing is to suppress crosstalk between cables laid in parallel. Routing of Cables Within and Outside Cabinets For electromagnetically compatible routing of cables and lines, it is expedient to subdivide the lines into the following line groups and lay the groups separately. Group A Shielded bus and data lines (for programmer, OP, SINEC L1, SINEC L2, PROFIBUS, PROFIBUS DP, printer, etc.) Group B Group C Group D Shielded analog lines Unshielded lines for DC voltage 60 V Unshielded lines for AC voltage 25 V Coaxial cables for monitors Unshielded lines for DC voltage > 60 V and 400 V Unshielded lines for AC voltage > 25 V and 400 V Unshielded lines for DC and AC voltage > 400 V Lines for SINEC H1 From the combination of individual groups in the following table, you can read off the conditions for laying the line groups. Group A Group B Group C Group D 3-12 Group A Group B Group C Group D System Manual C79000-G8576-C199-07 Installation Guidelines Legend for the table Routing of Cables Outside Buildings Lines can be laid in common bundles or cable ducts. Lines must be laid in separate bundles or cable ducts (without minimum clearance). Lines within cabinets must be laid in separate bundles or cable ducts; outside the cabinets but within buildings, they must be laid over separate cable routes with a clearance of at least 10 cm. Lines must be laid in separate bundles or cable ducts with a clearance of at least 50 cm. Outside buildings, lay the lines on metal cable trays if possible. Provide the joints between cable trays with an electrical connection and ground the cable trays. When laying lines outside buildings, you must observe the valid lightning protection and grounding measures. The following applies in general: Lightning Protection ! Caution Where cables and lines for SIMATIC S5 controllers are to be laid outside buildings, you must apply measures for internal and external lightning protection. Outside the buildings, lay your lines either in metal conduit grounded at both ends, or in concreted cable ducts with continuously connected reinforcement. Protect the signal lines from overvoltages by means of varistors or inert gas-filled surge diverters. Fit these protective devices at the cable entry into the building. Note Lightning protection measures always require an individual assessment of the entire installation. For clarification, please consult your Siemens regional office or a company specializing in lightning protection. Equipotential Bonding System Manual C79000-G8576-C199-07 Ensure adequate equipotential bonding between the connected equipment (see Section 3.3.2). 3-13 Installation Guidelines 3.3.2 Equipotential Bonding Between separate sections of an installation, potential differences can develop if Programmable controllers and I/O devices are connected via a non-floating link, or Cable shields are connected at both ends and are grounded at different parts of the system. Different AC supplies, for example, can cause potential differences. These differences must be reduced by installing equipotential bonding conductors to ensure functioning of the electronic components. The following points must be observed for equipotential bonding: The lower the impedance of the equipotential bonding conductor, the greater is the effectiveness of equipotential bonding. Where shielded signal lines are laid between the relevant sections of the system and connected at both ends to the ground/protective conductor, the impedance of the additional equipotential bonding conductor must not exceed 10 % of the shield impedance. The cross-section of the equipotential bonding conductor must be rated for the maximum circulating current. The following cross-sections of copper have proved to be satisfactory in practice: -16 mm of copper for equipotential bonding conductors of up to 200 m in length -25 mm of copper for equipotential bonding conductors of more than 200 m in length. Use copper or zinc-plated steel for equipotential bonding conductors. They must be given a large-area connection to the ground/protective conductor and protect it from corrosion. The equipotential bonding conductor should be laid so that the smallest possible areas are enclosed between the equipotential bonding conductor and signal lines. Signal Line Equipotential Bonding Conductor Figure 3-4 3-14 Routing of Equipotential Bonding Conductor and Signal Line System Manual C79000-G8576-C199-07 Installation Guidelines 3.3.3 Shielding of Cables and Lines Shielding is a method of attenuating magnetic, electrical or electro-magnetic interference fields. Interference currents on cable shields are given a path to ground via the shield bar which is electrically connected to the housing. A low-impedance connection to the protective conductor is particularly important so that these interference currents themselves do not become an interference source. Where possible, only use lines with a braided shield. The coverage density of the shield should be more than 80 %. Avoid lines with a foil shield because the foil can be very easily damaged by tensile strain and compression during fitting; this results in reduced effectiveness of the shield. Shields at Both Ends As a rule, line shields should always be connected at both ends. This is the only way to achieve a good degree of interference suppression in the higher frequency region. Only in exceptional cases should the shield be connected at one end only, as this only achieves attenuation of the low frequencies. Single-ended shield connection may be more advantageous when: an equipotential bonding conductor cannot be laid; analog signals (of a few mV or A) are to be transmitted; foil (static) shields are used. Data Lines As a rule, line shields should always be connected at both ends. This is the only way to achieve a good degree of interference suppression in the higher frequency region. With data lines for serial communication, always use metal or metallized connectors. Secure the shield of the data line to the connector case. Do not connect the shield to pin 1 of the connector. For stationary operation, it is advisable to fully strip the insulation from the shielded cable and connect it to the shield/protective conductor bar. Note In the event of potential differences between ground points, a circulating current may flow through the shield connected at both ends. In this case, install an additional equipotential bonding conductor (see Section 3.3.2). System Manual C79000-G8576-C199-07 3-15 Installation Guidelines Please observe the following points when connecting the shield: Use metal cable clamps for securing the braided shield. The clamps must enclose the shield over a large area and provide a good contact. 1) Connect the shield to a shield bar immediately after the cable entry into the cabinet. Route the shield as far as the module but do not connect it there again.

System Manual C79000-G8576-C199-07 Installation Guidelines 3.3.4 Special Measures for Interference-Free Operation Fitting Quenching Elements to Inductances As a rule, inductances such as contactor or relay coils controlled by SIMATIC S5 do not require external quenching elements in the circuit, because the quenching elements are already integrated in the modules. Inductances should only be fitted with quenching elements when SIMATIC S5 output currents can be switched off by additionally fitted contacts, such as relay contacts. In this case the integrated quenching elements in the modules are no longer effective; if they are not controlled by SIMATIC S5 modules. You can place freewheel diodes, varistors or RC networks in circuits with inductances.

The sockets should be powered from the distribution system to which the protective conductor for the cabinet is also connected. Cabinet Lighting Use incandescent bulbs, such as LINESTRA lamps, for cabinet lighting. Avoid using fluorescent lamps because they generate interference fields. If the use of fluorescent lamps cannot be avoided, apply the measures shown in the following figure. Screen Over the Lamp Shielded Cable Metal-Enclosed Switch AC Filter or Shielded Power Cable Figure 3-7 3-18 Measures for Interference Suppression of Fluorescent Lamps in a Cabinet System Manual C79000-G8576-C199-07 Installation Guidelines 3.3.5 Checklist for the Electromagnetically Compatible Installation of Control Systems EMC Measures Connection of inactive parts Notes (Section 3.2) Check, in particular, the connections on: Subracks Cabinet members Shield and protective conductor bars Do all inactive metal parts have a large-area, low-impedance interconnection and ground? Is there a satisfactory connection to the ground/protective conductor system? Have insulating layers on painted and anodized surfaces been removed, or have special contact washers been used for the connections? Are connections protected from corrosion, e.g. by grease? Are cabinet doors connected to the cabinet element with grounding strips? Routing of cables (Section 3.3.1) Cabling subdivided into line groups? Supply cables (230 to 400 V) and signal lines laid in separate ducts or bundles? Equipotential bonding (Section 3.3.2) With a separate arrangement, check that the equipotential bonding conductor has been correctly laid. Shielding of cables (Section 3.3.3) Have metal connectors been used throughout? Are all analog and data lines shielded? Are line shields connected to the shield or protective conductor bar at the cabinet entry? Are line shields secured with cable clamps over a large area and at low impedance? Are line shields connected at both ends where possible? Inductances (Section 3.3.4) Are contactor coils which are switched via contacts, fitted with quenching elements? System Manual C79000-G8576-C199-07 3-19 Installation Guidelines 3.4 Power Supplies for Programmable Controllers and I/Os This section describes: Which circuits you must distinguish in the control system and which demands are made on the power supply. Connection and grounding concept with higher-level infeed from grounded, centrally grounded and ungrounded supplies. Connecting the power supply to non-isolated and isolated modules. 3.4.1 Power Supplies for Control Systems with SIMATIC S5 For control systems with SIMATIC S5, you will need: A power supply for the internal PLC circuits (control power supply) and a load power supply for the input and output circuits. Power Supply for the PLC Circuits The power supply for the internal PLC circuits powers the CPU and the modules used. Note Ensure that the control power supply is not overloaded. Make a current addition and estimate the current drawn by all modules. Load Power Supply for the I/Os ! 3-20 The load power supply feeds the input and output circuits (load circuits) as well as sensors and actuators. Only a power supply which offers safe electrical isolation from the AC system may be used for the 24 V DC supply. Caution Only safety-separated low voltage DC 60 V may be used for the 24 V DC supply. The safety separation can be implemented according to the requirements of, amongst other sources, VDE 0100, Part 410/HD 384-4-41/IEC 60364-4-41 (functional extra-low voltage with safety separation) or VDE 0805/EN 60950/IEC 60950 (safety extra-low voltage SELV) or VDE 0106, Part 101. System Manual C79000-G8576-C199-07 Installation Guidelines Ratings of Load Power Supplies The electronic short-circuit protection of digital output modules only responds when 3-times the rated current is exceeded. You should therefore so design the load power supply units that the unit can supply the current required for shutting down in the event of a short-circuit at one output. In the event of short-circuits at digital outputs, if the load power supply is not adequately rated, a current which is higher than the rated current can flow for a longer period without responding of the electronic short-circuit protection of the DQ module. Operation in the overload region can destroy the module. Load Power Supply for Non-Floating Modules Load Power Supply for Floating Modules If you use non-floating modules, you must create a common reference potential for the internal control circuits of the PLC and for the load circuits. The reference potential of the load power supply should therefore be connected to the ground terminal of the PLC (PE or protective conductor terminal). The ground terminal is permanently connected to the internal reference potential of the controller. Note If you use switched-mode power supply units for floating analog modules and BEROs, you must fit an AC system filter to the input of the power supply. 3.4.2 Connecting the Programmable Controller and Load Power Each of the following figures shows a circuit example for connecting the control and load power supplies as well as the grounding concept for operation from: Grounded supplies Centrally grounded supplies Ungrounded supplies When assembling the control system, observe the following explanations. The text contains identification numbers relating to Figures 3-8 to 3-10. Main Switch and Protection For the programmable controller, sensors and actuators, you must fit a main switch to DIN VDE 0113, Part 1, or an isolating device to DIN VDE 0100, Part 460. If an AC plug is used as the isolating device, the socket must be in the vicinity of the central controller and must be easily accessible (VDE 0805, 1.7.2). These devices are not required in the case of a subsystem where the appropriate devices are fitted at a higher level. The circuits for sensors and actuators can be given group protection for short-circuit and/or overload . According to VDE 0100, Part 725, single-phase protection is required; and all-phase protection to DIN VDE 0113, Part 1. System Manual C79000-G8576-C199-07 3-21 Installation Guidelines Load Power Supply For 24 V DC load circuits, you require a load power supply unit with safety separation. If an AC plug is used as the isolating device, the socket must be in the vicinity of the central controller and easily accessible (VDE 0805, 1.7.2). Unregulated load power supply units require a reservoir capacitor (rated at 200 mF per 1 A load current). Connect the capacitor in parallel with the output terminals of the load power supply. According to DIN VDE 0113, Part 1, control systems with more than five items of electromagnetic apparatus require isolation by a transformer; according to DIN VDE 0100, Part 725, it is recommended . Grounding Load power supplies should be grounded if possible . Provide a detachable connection to the protective conductor at the load power supply unit (terminal L- or M) or on the secondary side of the isolating transformer. ! Caution For ungrounded power supplies, you must provide insulation monitoring if: hazardous system states can be caused by double faults; there is no safety separation; circuits are operated with voltages of more than 120 V DC; circuits are operated with voltages of more than 50 V AC. 3-22 System Manual C79000-G8576-C199-07 Installation Guidelines Operating a Programmable Controller with Process I/Os from a Grounded Supply L1 L2 L3 N PE Operation from grounded power supplies offers the best rejection of interference.

A detachable connection should be provided so that ground faults can be measured. The PLC should be insulated from cabinet/protective conductor potential. To maintain this isolated arrangement, all connected devices must be operated with capacitive grounding or ungrounded. For this reason, programmers should only be powered via an isolating transformer.

Operation of the PLC with non-floating power supplies is not allowed. When connecting the power supplies, please note: In 3 x 230 V systems, you may connect the power supply directly to two phases.

Intermediate transformers should be used in these systems. System Manual C79000-G8576-C199-07 3-25 Installation Guidelines 3.4.3 Connecting Non-Floating or Floating Modules Shown in the following sections are the specical features when installing non-floating and floating modules. Installation with Non-Floating Modules In an installation with non-floating modules, the reference potentials of the control circuit (0 Vint) and load circuits (0 Vext) are electrically connected. The reference potential of the control circuit (0 Vint) is given by the PE or protective conductor terminal and must be connected to the reference potential of the load circuit via an externally laid conductor. Shown in the following figure is a simplified installation with non-floating modules. The arrangement is independent of the grounding concept. The connections for grounding are therefore not drawn. Uint Data 0V CPU PS 1L+ 1L- PE Control Power Supply DQ External Connection for a Standard Reference Potential 2L+ 2L- DC 24 V Load Power Supply Figure 3-11 DI Simplified Representation of an Installation with Non-Floating Modules The voltage drop on line must not exceed 1 V. Otherwise there will be a shift in reference potentials resulting in module malfunctions. 3-26 System Manual C79000-G8576-C199-07 Installation Guidelines Note For 24 V DC digital output modules with electronic short-circuit protection, you must ensure that the reference potential of the load power supply is connected to terminal L- of the module. If this connection is missing (e.g. open-circuit), a typical current of 15 mA can flow at the outputs. This output circuit is sufficient to prevent energized contactors or relays from being released and to energize high-resistance loads (e.g. miniature relays). Installation with Floating Modules With floating modules the control circuit and load circuit are metallically isolated. An arrangement with floating modules is required for all AC load circuits and for DC load circuits which cannot be coupled. The reasons are, for example, different reference potentials of the sensors or grounding of the positive terminal of a battery. Shown in the following figure is a simplified installation with floating modules. The arrangement is independent of the grounding concept. The connections for grounding are therefore not drawn.

Information on component selection, the mechanical arrangement and wiring can be found in the appropriate reference manuals for the interface modules. Note If you use components which are not approved for the installation of a centralized or distributed interface circuit, interference rejection may be impaired. 3.5.1 Interference-Free Installation of Centralized Interface Circuits When you connect the central controller and expansion unit centrally via suitable interface modules, no particular shielding and grounding measures are required. Ensure, however, that all subracks are interconnected at a low resistance; the subracks in a grounded arrangement have star-configuration grounding; the contact springs of the modules are clean and not bent, which could affect the path to ground for interference currents. 3.5.2 Interference-Free Installation of Distributed Interface Circuits If you interconnect the central controller and expansion unit in a distributed arrangement using suitable interface modules, no particular shielding and grounding measures are usually required. Only in industrial environments with an extremely high level of interference is there a need for special shielding and grounding. In these cases, please observe the following points: Cable shields should be connected to the shield bar in the cabinet, immediately after the cable inlet; - insulation is fully stripped from the cable for the purpose; - braided shields are secured to the shield bar with as large an area as possible (e.g. with metal ties which enclose the shield over a large area). Shield bars should be connected to the frame or cabinet panel over a large area. Cable shields should be connected to the cabinet conductor. 3-28 System Manual C79000-G8576-C199-07 Installation Guidelines With distributed interfacing (IM 304/IM 314 and IM 301/IM 310), ensure that the VDE specifications for laying the protective ground are complied with; distributed interfacing is non-floating. The measures described above are shown in the following figure. If the permissible potential difference between ground points can be exceeded, you must install an equipotential bonding conductor (cross-section 16 mm2 of copper). CC EU IM 304 IM 314 Shield/Protective Conductor Bar <7V Figure 3-13 Shielding and Grounding the Connecting Cable Special Features System Manual C79000-G8576-C199-07 With distributed interfacing, you must use the prefabricated connecting cables. You may have excess lengths of up to 100 m when installing the connecting cable. These excess lengths must be bifilar-wound and deposited at a point which is protected from electromagnetic interference. 3-29 Installation Guidelines 3.6 Interference-Free Connection of Monitors These sections cover the following topics: Floating connection of cables at video inputs Shielding and grounding concept Information on selecting the components can be found in Catalog ST80. 3.6.1 Interference-Free Connection of a Monitor to the CP of the S5 Controller Operator control and process monitoring systems from the COROS product family can be used with monitor connections. The physical arrangement of apparatus and the interference level of the environment are important for the interference-free connection of monitors to SIMATIC S5 control systems. The choice of monitor and video cables is governed by the following: whether the monitor and PLC are to be operated under low-interference conditions or under industrial conditions. Operation of the Monitor and PLC under Low-Interference Conditions Where the monitor and PLC are installed under low-interference environmental conditions and operated over short distances, the monitor and PLC are at almost the same ground potentials. Interference and ground loop disturbances are therefore not expected. In these cases, you can drive the monitor both via TTL signals and via analog signals. Digital cables or single-shielded coaxial cables can be used to transmit the video signals. Note that the braided shield of the coaxial cable serves as the return conductor and must not be connected to the shield bar. The monitor and communication processor (CP) are interconnected without additional shielding and grounding. Operation of the Monitor and PLC under Industrial Conditions 3-30 Where the monitor and PLC are installed under harsh industrial conditions and operated over great distances, the devices may be at different ground potentials. These different ground potentials may cause interference and ground loop disturbances. System Manual C79000-G8576-C199-07 Installation Guidelines In these cases, double-shielded coaxial cables (triaxial cables) must be used to transmit the video signals. The inner braided shield of the coaxial cable serves as the return conductor and must not be connected to the shield bar. The outer braided shield provides a path to ground for interference currents and must be incorporated in the shielding and grounding measures. To avoid ground loops, the electronics ground and housing ground of the monitor must be independent. This requirement is met when: the electronics and housing grounds of the monitor are metallically isolated, or the electronics and housing grounds are connected via a voltage-dependent resistor (VDR) fitted by the manufacturer of the monitor. 3.6.2 Shielding and Grounding If the monitor and PLC are used under harsh industrial conditions, you must ensure the following at the PLC end: Cable shields should be connected to the shield bar in the cabinet, immediately after the cable inlet; - the video cables should be fully stripped; - the outer braided shield should be secured to the shield bar of the PLC over as large an area as possible (e.g. with metal ties which enclose the shield or with cable clamps). Shield bars should be connected to the frame or cabinet panel over a large area. Shield bars should be connected to the ground point of the cabinet. You must ensure the following at the monitor end: Separate the electronics ground and housing ground. - Remove the jumper at the monitor to separate the two grounds. Fit touch protection at the video sockets because hazardous touch voltages of more than 40 V may be present at the sockets after separation of the grounds. Connect the ground clamp of the monitor to the protective conductor. Connect the cable shields to the ground clamp of the monitor; - System Manual C79000-G8576-C199-07 fully strip the video cables; secure the outer braided shield to the ground clamp of the monitor over a large area. 3-31 Installation Guidelines Shown in the following figure is a simplified representation of the shielding and grounding measures for installing the monitor and PLC.

Further information on types of protection can be found in IEC 529. System Manual C79000-G8576-C199-07 3-33 Installation Guidelines 3.7.1 Types of Cabinet The following table provides on overview of the most common types of cabinet. It also shows the principle of heat removal, as well as the estimated, maximum achievable power loss removal and the type of protection* .

Heat accumulation usually occurs in the top of the cabinet. Heat removal only via the cabinet wall. Forced ventilation of the internal air results in improved heat removal and prevention of heat accumulation. Heat removal through exchange between heated internal air and cool outside air.

Then calculate the total power dissipation of the individual components. The following stipulations must be observed: The expansion units can be accommodated with the respective central controller in one cabinet, or in two or more cabinets (centralized or distributed). On account of the required clearances and maximum permissible installation height for control elements, a maximum of three SIMATIC S5 devices can be arranged one above the other. 3-34 System Manual C79000-G8576-C199-07 Installation Guidelines Load Power Supply Inlet Air Exhaust Air Subrack e.g. ER 701 See Table for Clearances Inlet Air Exhaust Air Subrack e.g. EU 184U See Table for Clearances Inlet Air Exhaust Air Subrack Baffle e.g. CC S5135U/155U Inlet Air Access Level 75 mm min., smaller clearances are possible with a closed cabinet roof and an additional, separate ventilation roof.

Maximum installation height for control elements: 2100 mm to DIN VDE 0106, Part 100, 2000 mm to DIN VDE 0113. Space for air circulation (400 mm deep cabinets are sufficient). Baffles are recommended to improve the air supply. Figure 3-15 Clearances in the Cabinet System Manual C79000-G8576-C199-07 3-35 Installation Guidelines Where subracks (CC and EU) are arranged one above the other, the installation clearances in the following table must be observed.

If subracks of the S5-135U/155U series are installed together with subracks of the S5-90U to 115U series in one cabinet, the rear panels of all subracks must be at the same distance from the rear wall of the cabinet. 3-36 System Manual C79000-G8576-C199-07 Installation Guidelines 3.7.3 Removal of Power Dissipation from Cabinets The power dissipation that can be removed from a cabinet is governed by the cabinet design, its ambient temperature and the arrangement of equipment in the cabinet. Shown in the following figure is a diagram with guide values for the permissible ambient temperature of a cabinet measuring 600 x 600 x 2200 mm, as a function of power dissipation.

Expansion units are connected when there are unsufficient central controller slots, or when you wish to position I/O modules as closely to the process as possible (see also Chapter 2). With the central controllers and some expansion units, the modules are directly powered and cooled via the integrated power supply plug-in module. With all other expansion units, power is supplied via the IMs from the CC (see also Chapter 7).

The housing contains the bus PCB for electrical and logical interconnection of the modules. All the slots have guiderails which accept the modules. Male and female connectors are thus precisely positioned. There is a locking bar at the top of the housing to prevent the modules from becoming accidentally detached. Modules with individual locking are secured in the lower sectional rail. There is a cable duct for incoming and outgoing cables at the front of the housing. Power Supply Unit The power supply unit with the fans is situated in the lower part of the central controller frame. Depending on the type of power supply, the input voltage is either 24 V DC or 230/120 V AC. The AC version can be adjusted to the required AC voltage with a selector switch.

The various modules carry out the following tasks: CPU The CPU processes the input signals of the PLC according to the user program, and emits the results as output signals. The following CPUs can be used in the S5-135U/155U PLC - CPU 948 - CPU 928B - CPU 928 - CPU 922 Coordinators By using a coordinator, you can configure the S5-135U/155U as a multiprocessor controller with up to four task-oriented CPUs in different combinations. Each CPU processes its program independently of the others. I/O modules The I/O modules provide the link to the process. IP module The intelligent I/O modules (signal pre-processing modules) off-load the CPU by independently executing compute-intensive tasks such as controlling, counting and positioning. Interface modules (IMs) If your CC has insufficient slots to insert all the modules required for your automation task, you can increase the number of modules with expansion units. The IM modules provide the link between central controller and expansion units. CP module CP modules allow point-to-point communication for data interchange between two PLCs, between one PLC and an external unit, between one PLC and a SINEC bus system or between one PLC and the COROS operator control and process monitoring system. You can use additional CP modules, such as the CP 581, CP 516, for the acquisition, storage, administration and preprocessing of large volumes of data. VP module VP modules enable the local acquisition and displaying (visualization) of process data of a PLC of the SIMATIC S5.

The mounting brackets can be fitted to the housing in the following ways: 5 32 16 Flush Figure 4-4 Fitting the Modules Methods of Fitting the Mounting Brackets The dimensions of the modules for the S5-135U/155U PLC comply with the double-height Eurocard format (h x d = 233.4 x 160 mm). There are modules with different mounting width. For example: Slots Occupied SPS 1) Front Plate Width in mm Example 1 1 1/3 20.3 CPU 922 2 2 2/3 40.6 CPU 948 4 1/3 81.3 CP 580 5 1) SPS standard-plug-in station: 1 SPS = 15.24 mm 4-8 System Manual C79000-G8576-C199-07 Central Controllers and Expansion Units Power Supply Units Proceed as follows to fit the modules: Step Action 1 Disconnect the CC from system power. 2 Slacken the two screws with which the locking bar is fixed to the subrack. 3 Pull the locking bar forward to its end stop. - The rail swivels up. 4 If there is a locking pin on the lower part of the module, turn it to the horizontal position. 5 Grasp the module at the front plate, insert it into the lower and upper guide rails and push it in. - 6 The connectors at the rear will engage in the sockets on the backplane bus, and the release lever on the lower part of the module will be horizontal. If a locking pin is fitted, push it in and rotate it 90 degrees. - If you have correctly fitted the module so far, it should no longer be possible to pull it out of the subrack. 7 Swivel the locking bar down and push it back into the subrack. 8 Retighten the two screws on the locking bar. Some I/O modules can also be fitted or removed during operation. Consult the reference manuals for the I/O modules, under "Release circuit." Free slots can be covered with dummy front plates. This improves the flow of cooling air in the unit. See the ordering information for order numbers. Connections of CPUs, CPs and IMs The connecting cables of CPUs, communication processors and EU interface modules are connected with metal front connectors. There are two types of metal front connector: A metal front connector with slide lock is secured after plugging it in, by sliding the lock downward. A metal front connector with milled screws is secured to the unit with the screws. Note Ensure that the connectors are assigned to the correct modules to avoid damage. The connection of signal lines for the I/O modules is described in Chapters 8 and 9. System Manual C79000-G8576-C199-07 4-9 Central Controllers and Expansion Units Power Supply Units 4.1.3 Startup Start up the CC in the sequence of steps given here. This will take you up to the first trial run of the CPU. Given in parentheses are references to the chapters of the manual in which the subject is explained in detail. To ensure a straightforward sequence for the startup, commence with one CPU and no EUs. Proceed according to the following steps to place the CC in operation: Step 4-10 Action 1 Install the PLC so that the supply of air and exhaust air are unimpeded. If you fit two or more units (CC and EU) in one cabinet, observe the clearances and use baffles where necessary (see Chapter 3). 2 Fit a lithium battery (see Sections 4.3 and 4.4) or connect an external backup battery and connect the rechargeable battery. 3 Fit the CPU and set the mode switch to STOP. 4 Connect the power supply and connect the 24 V DC load supply to the monitoring input. Check the setting of the voltage selector switch (on 230/ 120 VAC power supplies). Fit a protective cover over the AC terminals. 5 Switch on the power and, if present, the 24 V load supply. Position the "Power" switch I. Reaction: Green LEDs "Power Supply ok" in the "DC 5 V" field and in the "DC 15/24 V" field light up. 6 Hold the CPU switch in the OVERALL RESET position and move the switch from STOP to RUN. Reaction: The "Stop" LED flashes rapidly. 7 Repeat Step 6. Reaction: The "Stop" LED lights up constantly. 8 Keep the pushbutton in the RESET position and move the switch from STOP to RUN. Reaction: Green "Run" LED lights up, "BASP" LED (output inhibit) goes off.

System Manual C79000-G8576-C199-07 4-19 Central Controllers and Expansion Units Power Supply Units Basic Functions The power supply units offer the following functions: System power supply All the system voltages required for operation of the modules in a CC or EU are supplied. Power supply for backup (in the CC and EU 185): A lithium battery or an external battery ensure data backup when the system voltage is switched off or fails. - The lithium battery remains in the CC/EU and ensures backup, even during replacement of the power supply unit - Instead of the lithium battery, an external battery can be connected for data backup purposes. Situated on the front plate of the power supply unit are two sockets to connect an external battery. The rechargeable battery (in the power supply) continues to back up while either the lithium battery or external battery is being replaced or fails, ensuring that no data are lost. Heat removal Three independent fans which are individually replaceable during operation remove the dissipated power. If a fan fails, the supply voltage for this fan is switched off and the other two fans continue operation at increased speed. Monitoring Functions The power supply units contain monitoring functions to detect the following faults: Failure of system voltage Failure of output voltages Failure of an externally applied 24 V DC load voltage (voltage monitor) Fan failure or inadequate air flow Lithium battery failure Rechargeable battery failure In this context, a voltage failure is equivalent to a drop of the monitored voltage below a preset limit (see Section 4.3.6 of the Technical Specifications). Signaling Functions The failure of a monitored function is signaled by the power supply units: via LED indicators on the front plate; via relays with which signaling circuits can be switched; via signals to the S5 bus. 4-20 System Manual C79000-G8576-C199-07 Central Controllers and Expansion Units Power Supply Units Inputs and Outputs Based on the example of the 6ES5 955-3LF41 power supply unit, the following figure shows the arrangement of inputs and outputs on the front plate of the power supply units: SIEMENS 1 L1 N 2 3 4 5 I I + - 6 7 Warning Alarm max.

Behavior Upon Failure of the System Supply When the System Supply Fails Redundant Data Backup The behavior of the power supply unit after a system supply failure is governed by the duration of the failure: IF the system supply failure... THEN... is shorter than the stored energy time for power failure the PSU output voltages are within tolerance ranges; no indication appears on the front plate and no signal is sent to the S5 bus. is longer than the stored energy time for power failure a data save routine is initiated on the CPU/CPUs and an output inhibit is issued. To ensure data backup, your CC and EU 185 are provided with a lithium battery, and the power supply unit with a rechargeable battery. In the event of system supply failure or switch-off, data backup is provided by the lithium battery and, in the event of battery failure, by the rechargeable battery which is permanently recharged to remain constantly operative. After replacement of a defective lithium battery, the new one resumes data backup and you must acknowledge the fault LED on the front panel. As the rechargeable battery is withdrawn during the replacement of a power supply unit, data backup is temporarily performed by the lithium battery. System Manual C79000-G8576-C199-07 4-49 Central Controllers and Expansion Units Power Supply Units Behavior Upon Failure of Fans Failure Indication If a fan fails (its speed decreases) a fault is indicated, i.e. the red LED assigned to the fan lights up: "Fan 1" LED = left fan failed "Fan 2" LED = middle fan failed "Fan 3" LED = right fan failed If a Fan Fails If a fan fails, the following takes place: Stage If Another Fan Fails 1 A fan fails.

The terminals at the front are suitable for a conductor cross-section of up to 4 mm2, solid, or 2.5 mm2, flexible. Ensure adequate strain relief of the connections. You can add a 15 V auxiliary submodule to the 6ES5 955-3NA12 power supply unit (for example, if you wish to use SINEC H1). The auxiliary submodule produces a stabilized 15 V output voltage from the 24 V output voltage. The auxiliary submodule is short-circuit protected. The output voltage is monitored. If the voltage is too low, the green "15/24 V o.k." LED on the front plate goes off. If the voltage is too high, the output is short-circuited by a thyristor. 4-59 Central Controllers and Expansion Units Power Supply Units 4.4.2 Setting the Power Supply Unit Locations of Jumpers The figure shows the jumper settings when the unit is delivered.

Jumper F-R closed: Vo/p shutdown (signaled by contact) Jumper F-R open: no Vo/p shutdown (signaled by contact) If one or both fans are at standstill, the signaling relay drops out (monitor output). The "Fan Fault" LED lights up simultaneously. Relay contacts 2-1 closed: fan running Relay contacts 2-3 closed: fan failure Relay contacts 2-3 closed; this is also the normally closed contact during power OFF (failsafe). ! System Manual C79000-G8576-C199-07 Caution If an immediate shutdown is not possible, jumper F-R must be opened. In this case you must ensure that the power supply is switched off after 60 s at the latest. This can be achieved with a time relay, for example. It avoids overheating and destruction of modules. 4-61 Central Controllers and Expansion Units Power Supply Units Setting the Backup Battery Monitor As of Version 6 of PSU 6ES5 955-3NA12, you can set jumper RR-LL to choose whether the signaling relay (monitor output) should switch in the event of battery failure as well as fan failure: Jumper RR-LL open (state when delivered): relay will signal only a fan failure Jumper RR-LL closed: relay will signal a fan and battery failure. If the backup voltage fails or a fan is at standstill, or in both cases, the signaling relay will drop out (monitor output). The "Batt. Low" LED will also light up. Relay contacts 2-1 closed: battery backup voltage in order and fan running Relay contacts 2-3 closed: backup voltage under 2.7 V or fan failure Note The signaling relay in the power supply unit will drop out in the event of a fan fault or backup battery fault. The user's circuitry for the signaling relay must therefore be suitable for both types of fault. If the signaling relay drops out because of a backup battery fault and the programmable controller is therefore switched off, the program in the main memory may be lost. Loss of program can be avoided if an external backup voltage (3.4 V) is present at the sockets on the front plate of the power supply unit during shutdown of the programmable controller. 4-62 System Manual C79000-G8576-C199-07 Central Controllers and Expansion Units Power Supply Units 4.4.3 Installation To install the power supply unit, push it into the rack. Press it in firmly until the front plate is at the rack. The spring pressure of the contact elements must be overcome. Then tighten the two screws to the left and right of the front plate in the rack. The protective conductor jumper on the left must be permanently connected to the front plate terminal and the central rack. ! Caution Power supply units may only be removed when no power is applied. When the power supply unit is pulled out, the connection between backup battery and backplane bus is retained; the backup supply for the modules is thus ensured. Installing the 15 V Auxiliary Submodule The auxiliary submodule (see ordering information for order number) may only be inserted when the power is off. Remove the power supply unit, fit the 15 V auxiliary submodule at the location shown in the following figure. Connector X1 Connector X2 Transformer AA BB Space for LL RR Auxiliary Submodule Front Plate System Manual C79000-G8576-C199-07 4-63 Central Controllers and Expansion Units Power Supply Units 4.4.4 Operation Before placing the power supply unit in operation, please comply with the following. General Notes on the Power Supply Unit This power supply unit does not have potential isolation between its primary and secondary circuits. No voltage of more than 50 V may develop between the power supply outputs and the protective conductor of the power supply unit. The protective conductor must always be connected, as must the jumper between CC rack and front plate of the power supply unit. In the event of overvoltage of the internal DC supply voltages Vo/p1 = +5 V and Vo/p3 = +15 V, the power supply unit is switched off retentively. There is a voltage of 0.5 V at Vo/p1 and Vo/p3 in the Off state (see Section 4.4.6, Technical Specifications, for overvoltage shutdown). The storage flip-flop is reset by switching the external supply voltage off and on again, and the power supply unit is again operational if the overvoltage was not the result of an internal fault. You can insert an air filter with filter holder in the bottom of the housing of the power supply unit. Observe the voltage level of 3.4 V and correct polarity when applying an external backup voltage. Before startup, a lithium backup battery must be fitted or an external backup battery with a voltage level of 3.4 V DC must be connected. Without a backup battery, the programmable controller will remain in the Stop state when system voltage has been switched on. The backup battery must be fitted for startup. Press the RESET button, then perform an OVERALL RESET. The jumper from terminals UH to EN will enable the power supply. You can lock out the PLC in the event of a fault by means of suitable circuitry between the monitoring outputs and the EN inputs. 4-64 System Manual C79000-G8576-C199-07 Central Controllers and Expansion Units Power Supply Units Fault Indications/ Diagnostics Power supply faults are indicated via relay contacts and LEDs. The following table shows when the relay contacts are open or closed: Power Supply Relay Contacts 1-2 Relay Contacts 2-3 Switched off Open Closed In normal operation Closed Open During fault Open Closed The LEDs indicate the following faults: LED System Manual C79000-G8576-C199-07 Cause Action "Fan Fault" LED lights up.

Caution Incorrect replacement of the battery can result in the danger of explosion. It should only be replaced by the same type or an equivalent type recommended by the manufacturer. Used batteries should be disposed of according to the manufacturer's instructions. You can replace the backup battery without loss of data if the power supply unit is switched on, or if you apply an external voltage (3.4 V) at the "Ext. Batt." sockets. The backup battery must be replaced every 3 years at the latest, irrespective of memory configuration and backup operation. Replace the battery as follows: Step Action 1 Pull the cover downwards. 2 Pull the battery submodule forwards and out, and remove it. 3 Replace the battery. 4 Ensure correct polarity. 5 Once the new battery is fitted and system voltage is On, press the Reset button on the power supply unit. Battery Submodule + Sockets for External Backup Voltage * Battery Submodule Cover Only use battery submodules with the order number 6XG3 400-2CK00. 4-66 System Manual C79000-G8576-C199-07 Central Controllers and Expansion Units Power Supply Units ! ! Caution Ensure correct polarity when inserting the battery or applying backup voltage. Warning Risk of danger to persons and property, danger of giving off harmful substances. If handled incorrectly, a lithium battery can explode. If disposed of incorrectly, old lithium batteries can release harmful substances. You must therefore observe the following guidelines: Do not throw new or discharged batteries onto a fire and do not solder onto the body of the cell (max. temperature 100 C (212 F)). Do not recharge them. Order your replacement battery from Siemens only (for order number see ordering instructions). This ensures that you only use a short-circuit-protected type. The lithium battery is subject to regulations for hazardous materials. You should observe these regulations when you ship the battery, for example, by using the original packaging. Used batteries should be returned to the manufacturer or a recycling station if possible or disposed of as hazardous waste. The guidelines for transporting hazardous materials should be observed. Replacing the Fans The expected service life of the fans (see Technical Specifications) depends on their operating time, ambient temperature and ambient conditions. In the event of fan failure during operation, subsequent damage to modules, for example, is avoided by the activated fan monitor (jumper F-R closed); the power supply unit is switched off. In individual cases, a preventive replacement of fans at suitable intervals may be advisable. Proceed as follows to replace the fans: Step Action 1 Disconnect power from the power supply. 2 Remove the power supply. 3 Slacken the fixing screws of the fans. 4 Pull off the plug-in contacts of the fan supply. 5 Connect the plug-in contacts of the new fans. 6 Tighten the fixing screws of the fans. 7 Refit the power supply. 8 Switch the power supply on. The order numbers for the backup battery and fan unit can be found in the ordering information.

PG Interface SI1 You can use the PG interface on the CPU 948 either via the front connector or via the 923C coordinator module and the S5 bus. Note Simultaneous operation of the PG interface via the front connector of the CPU 948 and via the 923C coordinator is not possible. Switching the PG online without a job request is already sufficient to operate the interface. Electrically, it is merely a PG interface which can be operated via two different terminals. The connection to the PG can be established in every operational state of the CPU. Second Interface SI2 You can optionally use the second interface of the CPU 948 -3UA13 or the CPU 948 -3UA23 as: A PG interface (for PG and operator panels) Interface for the RK 512 computer link Interface for data transmission with procedures 3964/3964R Interface for data transmission with the "open driver" Interface for data transmission via the SINEC L1 bus. To utilize the second interface as the PG interface, you need the PG submodule. You need one of the following interface submodules for the RK 512 computer link, for data transmission with procedures 3964/3964R and for data transmission with the "open driver": V.24 submodule (RS 232C) TTY submodule RS422 A/485 submodule (only in the RS422 A module). To utilize the second interface for data transmission via the SINEC L1 bus, you need the SINEC L1 submodule. The CPU 948 -3UA13 or the CPU 948 -3UA23 is delivered without an interface submodule. You can operate the CPU 948 -3UA13 or the CPU 948 -3UA23 without an integral interface submodule. The opening to accept a submodule in the front plate is closed by a cover. Only remove the cover to fit an interface submodule. A description of interface submodules can be found in Section 5.11, and the order numbers in the ordering information. A detailed description of the second interface can be found in the CPU 928B/CPU 948 Communication Manual.

Details on programming the CPU 948 can be found in the CPU 948 Programming Guide. 5.2.1 Technical Description This section contains information on the application, design and structure of the CPU 948. Application You can use the CPU 948 in single and multiprocessor operation in the S5-135U/155U central controller (see Chapter 6). There are two versions of CPU 948: The CPU 948-1 offers 640 Kbytes of internal user memory (RAM). The CPU 948-2 offers 1664 Kbytes of internal user memory (RAM). A SIMATIC S5 flash EPROM memory card (known as a memory card for short in the following) can be inserted in the CPU 948 as the storage medium for user program and user data. The contents of the memory card are copied into the internal RAM of the CPU upon overall reset. The programming language is STEP 5 (LAD, CSF, STL, SCL). The CPU 948 processes all STEP 5 operations at very high speed, and uses fast floating-point arithmetic. The following program processing levels are possible: Cyclic Time-controlled (9 different timebases, real-time controlled, timeout) Interrupt-driven from the S5 bus (8 process interrupts at block boundaries via IB0 or, alternatively, 4 system interrupts) Soft STOP. Design System Manual C79000-G8576-C199-07 The electronic circuitry of the CPU 948, including the RAM, is on two PCBs of double Eurocard format which are screwed to each other. The two PCBs must not be separated. The front plate width of the module is 2 2/3 standard plug-in stations, i.e. 40 mm. In the central controller rack, the CPU 948 occupies two slots. 5-17 CPUs, Memory Cards, Memory Submodules, Interface Submodules 5.2.2 Installation and Startup This section explains the installation and removal of the module in the CC, controls and indicators on the front plate of the CPU, and the procedure for module startup. Jumper Settings There are four system interrupts for interrupt-driven program processing with the CPU 948: INTA/B/C/D (depending on the CPU slot, see also Section 4.1.1) INTE INTF INTG. The interrupts you wish to use must be enabled by inserting the jumper plugs provided. The jumper socket is situated on the basic board above the receptacle for the memory card. The exact location is given in Figure 5-3: INTG INTF INTE INTA/B/C/D View of underside of module Front panel Jumper Figure 5-3 Location of Jumper Socket Location of an Additional Jumper for the Functions Described Below If you want to operate an IM308C in the IM3/IM4 area and additional digital or analog modules in the central controller, you must insert the jumper shown in Figure 5-3. 5-18 System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules Note All other jumpers are required for quality testing by the manufacturer. You must not change these jumper settings. Removing and Inserting the Module ! Caution Switch off the power supply before removing or inserting the module. The basic board and expansion board of the CPU 948 are one unit and must not be separated.

Up to four CPUs can be used. The CPU 928B is universally applicable, ensuring both very fast bit processing and very fast word processing. The following program processing levels are possible: Cyclic Time-controlled (9 different timebases) Real-time controlled Interrupt-driven (hardware interrupt) Delayed The programming language is STEP 5. Design The electronic circuitry of the CPU 928B is on one PCB in the double Eurocard format. The board provides the connection to the S5 bus via two backplane connectors. The front plate width is 1 1/3 standard plug-in stations. 5-30 System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules User Memory For storage of your program, user memory in the form of RAM is integrated on the board. You can store up to 64 x 210 bytes of code and data blocks here. For data blocks, the CPU 928B additionally has an integrated DB RAM of 46 3/4 x 210 bytes. Memory Card As an external memory medium for user programs and user data, you can use a memory card 374 with Flash EPROM. PG Interface SI1 There are two independent interfaces on the front of the CPU 928B. You can connect programmers and OPs to the first interface. This PG interface SI1 is permanently installed on the CPU. You can use PG interface SI1 either via the front connector of the CPU 928B or via the front connector of the 923C coordinator module. Note Simultaneous operation of PG interface SI1 via the front connector of the CPU 928B and of the coordinator is not possible. Electrically, it is merely a PG interface which can be operated via two different terminals. Switching the programmer online without a job request is already sufficient to operate the interface. If you wish to utilize a second PG interface for connection of a PG or OP, the connection must be made via the second PG interface with the PG submodule. Apart from PG interface SI1, the second interface SI2 can also be used as a PG interface in parallel with the first one. You can only use the second PG interface via the front connector of the PG submodule on the CPU 928B. A detailed description of operations with the two PG interfaces can be found in the CPU 928B -3UB21 Programming Guide. The connection to the PG can be established with the CPU in any operational state. System Manual C79000-G8576-C199-07 5-31 CPUs, Memory Cards, Memory Submodules, Interface Submodules Second Interface SI2 You can optionally use the second interface of the CPU 928B as: A PG interface (for PG and operator panels) Interface for the RK 512 computer link Interface for data transmission with procedures 3964/3964R Interface for data transmission with the "open driver" Interface for data transmission via the SINEC L1 bus (from Version 6ES5 928-3UB12). To utilize the second interface as the PG interface, you need the RG submodule You need one of the following interface submodules for the RK 512 computer link, for data transmission with procedures 3964/3964R and for data transmission with the "open driver": V.24 submodule (RS 232C) TTY submodule RS422 A/485 submodule (only in the RS422 A mode). To utilize the second interface for data transmission via the SINEC L1 bus, you need the SINEC L1 submodule (from Version 6ES5 928-3UB12). The CPU 928B is delivered without an interface submodule. You can operate the CPU 928B without an integral interface submodule. The opening to accept a submodule in the front plate is closed by a cover. Only remove the cover to fit an interface submodule. A description of interface submodules can be found in Section 5.11, and the order numbers in the ordering information. A detailed description of the second interface can be found in the CPU 928B/CPU 948 Communication Manual. Process Interrupt Processing There is an interrupt line in the PLC for each CPU. It can be used when the reaction to an event must occur with higher priority than the reaction to other events. To process an interrupt, cyclic program processing is interrupted and the program stored in OB 2 (OB for interrupt processing) is inserted (refer to the CPU 928B -3UB21 Programming Guide for further details). This interrupt-driven program processing is only possible using an interrupt-capable digital input module or a suitable operating CP/IP module. No jumper setting on the CPU 928B is required.

Details on programming the CPU 928B can be found in the CPU 928B Programming Guide. 5.4.1 Technical Description Application You can use the CPU 928B in single and multiprocessor operation in the S5-135U/155U central controller (see Chapter 6). Up to four CPUs can be used. The CPU 928B is universally applicable, ensuring both very fast bit processing and very fast word processing: Cyclic Time-controlled (9 different timebases) Real-time controlled Interrupt-driven (hardware interrupt) Delayed (from Version 6ES5 928-3UB12) The programming language is STEP 5. Design The electronic circuitry of the CPU 928B is on two PCBs (basic and expansion boards) in the double Eurocard format. Both PCBs are screwed together, linked via connectors, and must not be separated. The basic board provides the connection to the S5 bus via two backplane connectors. The front plate width is 2 2/3 standard plug-in stations. 5-42 System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules User Memory You require a user memory submodule (RAM or EPROM) for storage of your program. You can store up to 64 x 210 bytes of code and data blocks here. For data blocks, the CPU 928B additionally has an integrated DB RAM of 46 x 210 bytes. A description of the memory submodules can be found in Sections 5.9 and 5.10; order numbers are given in the ordering information. PG Interface SI1 There are two independent interfaces on the front of the CPU 928B. You can connect programmers and OPs to the first interface. This PG interface SI1 is permanently installed on the CPU. You can use PG interface SI1 either via the front connector of the CPU 928B or via the front connector of the 923C coordinator module. Note Simultaneous operation of PG interface SI1 via the front connector of the CPU 928B and of the coordinator is not possible. Electrically, it is merely a PG interface which can be operated via two different terminals. Switching the programmer online without a job request is already sufficient to operate the interface. If you wish to utilize a second PG interface for connection of a PG or OP, the connection must be made via the second PG interface with the PG submodule. Apart from PG interface SI1, the second interface SI2 can also be used as a PG interface in parallel with the first one. You can only use the second PG interface via the front connector of the PG submodule on the CPU 928B. A detailed description of operations with the two PG interfaces can be found in the CPU 928B Programming Guide. The connection to the PG can be established with the CPU in any operational state. System Manual C79000-G8576-C199-07 5-43 CPUs, Memory Cards, Memory Submodules, Interface Submodules Second Interface SI2 You can optionally use the second interface of the CPU 928B as: A PG interface (for PG and operator panels) Interface for the RK 512 computer link Interface for data transmission with procedures 3964/3964R Interface for data transmission with the "open driver" Interface for data transmission via the SINEC L1 bus (from Version 6ES5 928-3UB12). To utilize the second interface as the PG interface, you need the PG submodule. You need one of the following interface submodules for the RK 512 computer link, for data transmission with procedures 3964/3964R and for data transmission with the "open driver": V.24 submodule (RS 232C) TTY submodule RS422 A/485 submodule (only in the RS422 A module). To utilize the second interface for data transmission via the SINEC L1 bus, you need the SINEC L1 submodule (from Version 6ES5 928-3UB12). The CPU 928B is delivered without an interface submodule. You can operate the CPU 928B without an integral interface submodule. The opening to accept a submodule in the front plate is closed by a cover. Only remove the cover to fit an interface submodule. A description of interface submodules can be found in Section 5.11, and the order numbers in the ordering information. A detailed description of the second interface can be found in the CPU 928B Communication Manual. Process Interrupt Processing There is an interrupt line in the PLC for each CPU. It can be used when the reaction to an event must occur with higher priority than the reaction to other events. To process an interrupt, cyclic program processing is interrupted and the program stored in OB 2 (OB for interrupt processing) is inserted. (Refer to the CPU 928B Programming Guide for further details.)

Details on programming the CPU 928 can be found in the CPU 928 Programming Guide. 5.6.1 Technical Description Application You can use the CPU 928 in single and multiprocessor operation in the S5-135U/155U central controller (see Chapter 6). Up to four CPUs can be used. The CPU 928 is universally applicable, ensuring both very fast bit processing (optimized for open-loop tasks) and word processing (optimized for closed-loop tasks). The following program processing levels are possible: Cyclical Time-controlled (9 different timebases) Interrupt-driven (hardware interrupt) The programming language is STEP 5. Design The CPU 928 comprises two PCBs (PCB 1 and PCB 2) in the double Eurocard format, in a sandwich assembly. The two PCBs have plug-in interconnections and are bolted together as a unit when delivered. PCB 2 serves as the basic board which provides the connection to the S5 bus via two backplane connectors. The front plate width is 2 2/3 standard plug-in stations. 5-62 System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules User Memory You require a user memory submodule (RAM or EPROM) for storage of your program. You can store up to 64 x 210 bytes of code and data blocks here. For data blocks, the CPU 928 additionally has an integrated DB RAM of 46 x 210 bytes. Note The DB RAM is loaded with DB/DX blocks when the RAM submodule is full or an EPROM submodule is plugged in. A description of the memory submodules can be found in Sections 5.9 and 5.10; order numbers are given in the ordering information. Process Interrupt Processing There is an interrupt line (IR) in the PLC for each CPU. It can be used when the reaction to one or more events must occur with higher priority than the reaction to other events. To process an interrupt, cyclic program processing is interrupted and the program stored in OB 2 (OB for interrupt processing) is inserted. (Refer to the CPU 928 Programming Guide for further details.) This interrupt-driven program processing is only possible using an interrupt-capable digital input module (e.g. 6ES5 432-...) or a CP/IP module which operates in this way.

Note You cannot use the memory submodule 377 for the CPU 928B from version 3UB21, nor for the CPU 928 from version 3UA21. 5.10.1 Technical Description 377 memory submodules (RAM submodules) are available with or without battery backup in the following capacities: Without Battery Backup With Battery Backup 16 Kbytes 64 Kbytes 32 Kbytes 64 Kbytes The order numbers for the 377 memory submodules can be found in the ordering information. 5.10.2 Notes on Operation Loading RAM Submodules 5-84 377 memory submodules are loaded online (from the PG) in the CPU. A description of loading the individual submodules or the entire program can be found in the STEP 5 manual. System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules 5.10.3 RAM Submodules with Battery Backup RAM submodules with battery backup are used when the contents of the memory submodules must be retained even outside the CPU. You can then remove the battery-backed 377 memory submodule from the CPU without loss of data. An integral battery protects the submodule from data loss, and ensures that the data will be retained until the RAM submodule is used again. Note The RAM submodule with battery backup is not a substitute for an EPROM submodule. The contents can be overwritten by a STEP 5 program. The battery can discharge if the submodule is at standby for a long time. This can result in the loss of data. To protect the battery, the 377 memory submodule has a cover on both sides. The button cell battery with terminal lugs is secured on the submodule with screws on two holders. When the grip is swivelled in, you can see the battery fault LED. Operational States There are three different operational states for the RAM submodule with battery backup: Normal Operation In this state the battery-backed RAM submodule is in the CPU; the programmable controller (PLC) is switched on (Power On); and neither the backup battery of the PLC nor the battery of the RAM submodule is supplying power. Note The RAM submodule must not be inserted or removed during the RUN state; this can result in data corruption, loss of data or CPU malfunctions. System Manual C79000-G8576-C199-07 5-85 CPUs, Memory Cards, Memory Submodules, Interface Submodules Standby Operation In this standby state of the unit the battery-backed RAM submodule is in the CPU; the PLC is switched off (Power Off); the backup battery of the PLC is providing backup of the RAM submodule; the submodule battery is not supplying power. Note It is only possible to insert and remove the RAM submodule in this state without data corruption. If the backup battery in the PLC fails in this state, the submodule battery provides backup of the RAM submodule. This prevents loss of data. Submodule Standby In this standby state of the submodule the RAM submodule has been removed from the CPU; the submodule battery is providing backup of the RAM submodule; the contents of the battery-backed RAM are retained. Battery Monitoring and Battery Fault The battery of the battery-backed RAM submodule is monitored. When the RAM submodule goes to normal operation (battery-backed RAM is in the CPU, supply voltage of the PLC is switched on), the battery monitor on the submodule detects the following faults: Submodule battery is not present. Submodule battery is faulty (voltage less than 2.6 V). The red battery fault LED on the front of the submodule is continuously lit. Note A temporary voltage drop of the submodule battery in the standby state, for example, caused by storage below 0 oC or a battery change, is not detected by the battery monitor if the voltage dip is corrected by plugging in the RAM submodule and switching on the PLC. However, the voltage dip may have led to a loss or corruption of RAM submodule data. 5-86 System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules Inserting or Replacing the Backup Battery Before the RAM submodule with battery backup is started for the first time, you must insert the battery provided. This is delivered separately to protect it from premature discharge. Proceed according to the following steps: Step Action 1 Open the upper side of the cover by releasing the snap-on catch. Grasp the cover within the clearance from the PCB and pull it up. 2 Insert the submodule battery and secure it with a screw on the left and on the right. Ensure correct polarity (+/-). 3 Close the cover again. Battery M 2.5 Screw Battery Fault LED Grip Figure 5-10 ! Mounting Location for Backup Battery Caution Improper replacement of the battery can result in explosion hazard. It should only be replaced by the same type or an equivalent one recommended by the manufacturer. Used batteries should be disposed of according to the manufacturer's instructions. System Manual C79000-G8576-C199-07 5-87 CPUs, Memory Cards, Memory Submodules, Interface Submodules Proceed as follows to replace the submodule battery: Step Action 1 Open the upper side of the cover by releasing the snap-on catch. 2 Slacken the screws on the left and right of the battery. 3 Replace the submodule battery and secure the new battery with screws, observing the polarity. 4 Close the cover again. Using the RAM Submodule with Battery Backup ! Caution EPROM-battery-backed RAM submodules must not be programmed via the EPROM interface of the PG, otherwise they can be destroyed. Before inserting or removing the RAM submodule into or out of the CPU, switch the PLC power supply off: this is to ensure that data of the RAM submodule are not corrupted. Inserting Unprogrammed Memory Submodules Initial situation: The CPU is in the programmable controller. The power supply of the PLC is switched off. The mode switch of the CPU is at STOP. Step 5-88 Action 1 First insert the battery in the RAM submodule. 2 Insert the RAM submodule in the CPU. 3 Switch the power supply of the programmable controller on. 4 Carry out an overall reset. 5 Connect your programmer (PG) to the CPU. 6 When the user program has been loaded into the RAM submodule, reset the CPU. System Manual C79000-G8576-C199-07 CPUs, Memory Cards, Memory Submodules, Interface Submodules Inserting Programmed Memory Submodules Since the contents of the inserted RAM submodule are erased with each overall reset, proceed as follows when using programmed RAM submodules whose contents are not to be erased: Initial situation: The CPU is in the programmable controller. The power supply of the PLC is switched off. The mode switch of the CPU is at STOP. Step Removing Memory Submodules Action 1 Insert another, unprogrammed memory submodule in the CPU. 2 Switch the power supply on. 3 Carry out an overall reset. 4 Switch the power supply off. 5 Remove the unprogrammed memory submodule. 6 Insert the programmed memory submodule. 7 Switch the power supply on. 8 Carry out a reset. Before removing the RAM submodule, check whether the battery is still in order: if the battery fault LED on the RAM submodule is lit whilst the PLC supply voltage is switched on, the contents of the RAM submodule will be lost when it is removed. Initial situation: The CPU is in the RUN state. Step System Manual C79000-G8576-C199-07 Action 1 Set the CPU mode switch to STOP. 2 Switch the power supply off. 3 Remove the memory submodule. 5-89 CPUs, Memory Cards, Memory Submodules, Interface Submodules 5.10.4 Technical Specifications Important for the USA and Canada The following approvals have been obtained: UL Listing Mark Underwriters Laboratories (UL) to Standard UL 508, Report E 85972 CSA Certification Mark Canadian Standard Association (CSA) to Standard C 22.2 No. 142, Report LR 63533 All 377 Memory Submodules Supply voltage +5 V 5% Operating temperature 0 to 55 C Storage temperature - 40 C to 70 C Relative humidity Up to 95 % at 25 C, no condensation Number of programming cycles 10,000 Dimensions (H x D x W) 54 x 58 x 14 mm Weight Approx. 40 g / 60 g Submodules without Battery Backup 5-90 Current consumption (at 5 V) 100 mA max.

Data Transmission Rate A maximum of 19200 bps is permissible for data transmission with the RS422 A/485 submodule when used in a CPU or CP 524. When the CP 544 is used, a maximum of 76800 bps is possible.

The PLC can be used both in single and in multiprocessor operation with up to four CPUs. Slots Occupied You can arbitrarily combine the CPUs in the central controller at the CPU slots. CPU Slot Requirement CPU 948/CPU 928B/CPU 928 2 slots CPU 922, 928-3UA21, 928-3UB21, 948-3UA13, 948-3UA23 1 slot In multiprocessor operation, each CPU processes its individual user program independently of the other CPUs. The common S5 bus serves for data interchange with I/O modules, CPs, IPs and other CPUs. In multiprocessor operation, access of the CPUs to the S5 bus is controlled by a coordinator. The functioning of this module is described in Sections 6.5 and 6.6. For an explanation of data interchange between CPUs in multiprocessor operation and the arrangement of your STEP 5 program, please consult the Programming Guide for your CPU. Coordinator A coordinator is required in multiprocessor operation. The following exist for the S5-135U/155U PLC: 923A coordinator (COR A) (is no longer supplied) and 923C coordinator (COR C). The coordinator allocates to the CPUs the time divisions in which they can access the S5 bus (bus enable time), and contains the global memory for data interchange between the CPUs via communication flags. Additionally, the COR C contains another memory with four pages for the "multiprocessor communication" function as well as a serial PG interface with PG multiplexer function (PG MUX). 6-2 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators 6.2 Starting the Multiprocessor Operation This section guides you through the installation and startup of multiprocessor operation; the following is assumed: You are familiar with the use and programming of individual modules in single-processor operation. If this is not the case, please consult the relevant chapters in this manual and in the appropriate Programming Guides. Note As soon as a coordinator is inserted in the S5-135U/155U central controller, all CPUs are automatically in multiprocessor operation irrespective of the number of inserted CPUs. Even if the coordinator is only operated with one CPU, the conditions for multiprocessor operation apply to this CPU (DB 1 required, DX 0 possibly required, etc.). Procedure, Overview You can use up to four CPUs in the S5-135U/155U programmable controller. The permissible slots are indicated in Chapter 4. Startup can be subdivided into the following steps: Step System Manual C79000-G8576-C199-07 Action 1 Set the number of CPUs (inserted from the left) on the coordinator. 2 If you use communication flags on CPs: Mask out the communication flag areas on the coordinator. 3 Insert the CPUs and the coordinator in the slots provided in the central controller. The CC must be disconnected from system voltage. 4 Switch on the system voltage and power switch on the power supply unit. 5 Execute an OVERALL RESET on all CPUs. 6 Load your STEP 5 user programs in all CPUs (including DB 1, additionally DX 0 for the CPU 948). 7 Execute a RESET on all CPUs. 8 Set the mode switch of the coordinator from the STOP to RUN or TEST setting. 6-3 Multiprocessor Operation/Coordinators Setting the Jumpers Shown in Figures 6-1 and 6-2 are the locations of jumpers and switches on the modules, at which the settings required for startup must be made.

The 256 communication flag bytes can be masked out in groups of 32. You do this by removing jumpers at coding socket EP 7 on coordinator A (see Figure 6-1 for location) or EP 60 on coordinator C (see Figure 6-2).

Substep Reaction 3a Insert the CPUs and coordinator in the relevant slots. none 3b Insert all EPROM or RAM submodules in the CPUs according to the configuration. The EPROM submodules must have been previously programmed with a PG. none Set all mode switches on the CPUs and on the coordinator to STOP. none 3c 6-8 Action System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators Step 4 Action Switch the supply voltage on. Reaction 1. The red STOP LEDs flash rapidly on all CPUs to indicate: Overall reset requested. 2. If the test mode is not set at the coordinator (see Section 6.3) and the mode switch is not at the TEST setting: The red BASP (output inhibit) LED is permanently lit to indicate: Digital outputs are inhibited. Possible Faults Symptom: On some CPUs the STOP LED is not lit; the other CPUs are requesting OVERALL RESET. All CPUs are emitting the BASP (output inhibit) signal. Remedy: Check the setting for the number of occupied CPU slots on the coordinator. Are the CPUs inserted at suitable slots? Step 5 Executing an OVERALL RESET on all CPUs: Ensure that the mode switch on the coordinator is set to STOP. (Precondition: Steps 3 and 4 have been fully executed. Action Reaction Execute the OVERALL RESET for each individual CPU: The red STOP LEDs on the CPUs at which the OVERALL RESET was executed, light up continuously. Each CPU additionally emits the output inhibit signal (BASP LED continuously lit). Hold the operating mode switch in the OVERALL RESET setting; simultaneously set the mode switch from STOP to RUN and back to STOP. System Manual C79000-G8576-C199-07 6-9 Multiprocessor Operation/Coordinators Step 6 Loading STEP 5 user programs in all CPUs: Recommended precondition: The programs of the individual CPUs have already been tested in single-processor operation. For details of loading STEP 5 blocks and using the different types of memory, please consult the relevant Programming Guides of the CPUs and your PG Manual. Prerequisites What? Where? Data block DB 1 must be present for I/O allocation. in all CPUs 1) Data block DX 0 must additionally be present at CPU 948. only in CPU 948 The mode for "Process interrupts via IB 0 = off" must be set in DX 0. To start multiprocessor operation immediately with all CPU programs, you must now load your programs into the individual CPUs. into the desired CPU 1) After completing these steps, however, you can load individual programs into certain CPUs. 1. You must only load the blocks for CPUs with RAM operations; for EPROM operation, the inserted EPROMs must contain your user program with DB 1 (DX 0). Data blocks which you have provided for dynamic data storage must be copied after a RESET by program into the RAM. Reaction There is no change in the reactions of step 4 (each CPU still emits the output inhibit signal: the BASP LED is continuously lit). 6-10 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators Step 7 Executing a RESET at all CPUs: Action Reaction Execute a RESET at each individual CPU: Hold the MC 1) mode switch at the RESET setting; simultaneously set the mode switch from STOP to RUN. The red STOP LED on each CPU is continuously lit; each CPU emits the output inhibit signal. The CPUs are in the wait state. 1) Possible Faults MC: Momentary-contact Symptom 1: The STOP LED of one CPU flashes slowly. When the control bits of this CPU are read out with the programmer, "DB 1 error" is marked in addition to the usual information. There is no output of an ISTACK. Remedy: Check whether data block DB1 in the CPU was correctly loaded and programmed. Symptom 2: After execution of a RESET: Undefined states or faults occur at the CPUs (for example, after a RESTART at CPU 922, it goes to the RUN state although the other CPUs are still at STOP). Remedy: Verify the following points: Is the coordinator inserted? Are all modules correctly inserted (engaged)? Are all modules at the correct slots? System Manual C79000-G8576-C199-07 6-11 Multiprocessor Operation/Coordinators Step 8 Setting the coordinator mode switch to RUN or TEST: IF ... Reaction You do not wish to Set the coordinator work in the test mode 1) mode switch from STOP to RUN. The green RUN LEDs of all CPUs are continuously lit. All CPUs simultaneously go into the cycle. The output inhibit signal is not emitted (BASP LED = off). You wish to work in the Set the coordinator test mode (it must be mode switch from enabled on the STOP to TEST. coordinator) 1) Set the coordinator mode switch from STOP to TEST. 1) Possible Faults THEN ... Test mode and setting: see Section 6.3 Symptom: All CPUs remain in the Stop state. Remedy: Check whether the mode switches of all CPUs are set to RUN. A subsequent start of individual CPUs is not possible. Switch the coordinator back to STOP. Execute a RESET at all CPUs and then switch the coordinator to RUN again. Note During the starting phase (processing of the start OBs) the STOP and RUN LEDs remain off at all CPUs. The RUN LED only lights up continuously when the CPUs go over to cyclic program processing. Notes Relating to Multiprocessor Start When the coordinator is switched from STOP to TEST, only the CPUs whose switches are at the RUN setting will operate in the test mode. If the 923C coordinator is used and the PG interface on the front plate is not connected to the PG and switched online, the IF FAULT LED lights up on the 923C coordinator. The indicator can be ignored in this case. 6-12 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators 6.3 Coordinator Modes The Stop State If, when the supply voltage is switched on, the coordinator mode switch is at STOP or another stop request is pending, the CPUs remain in the Stop state. Startup AUTOMATIC RESET or AUTOMATIC RESTART If, when the supply voltage is switched on, the coordinator mode switch is at RUN, an AUTOMATIC RESET or AUTOMATIC RESTART (depending on DX 0 setting) will take place as long as the mode switches of the CPUs are also at RUN and the PLC was previously in cyclic operation. MANUAL START When you set the coordinator mode switch from STOP to RUN, the CPUs will execute a start if this was already prepared at all CPUs by appropriate switch actuation, i.e. the CPUs are in the wait state. As required by the user, the type of start can be the same for all CPUs or arbitrarily different. After the start synchronization by the system programs, the CPUs simultaneously go to RUN (cyclic operation). Normal Operation and Stop in the Event of Faults The transition of individual CPUs is synchronized - as long as the preset "start synchronization" in the relevant CPUs has not been changed by DX 0 programming - i.e. only when each CPU has ended its start do all CPUs jointly go to cyclic program processing. If the coordinator mode switch is at the RUN setting and one CPU goes to the Stop state, all the other CPUs also go to the Stop state. The red STOP LED(s) on the CPU(s) causing the Stop state flash slowly; the STOP LEDs of the other CPUs are continuously lit. Apart from any indication with fault LEDs on the CPU which is the cause, all CPUs emit the BASP (output inhibit) signal. System Manual C79000-G8576-C199-07 6-13 Multiprocessor Operation/Coordinators Test Mode ! Warning Since, in the test mode, no CPU can emit a BASP (output inhibit) in the event of a fault, the test mode must be switched to the inactive state without fail after completion of startup to avoid a critical or even hazardous system state. Before you can go into the test mode with the TEST switch, you have to enable it on the module. This is achieved differently with the 923A and 923C coordinators. Enabling the Test Mode with the 923A Insert jumper 3 - 14 on coding socket EP 45 as shown in the following sketch. 16 9 14 EP 45 923A Coordinator 1 Enabling the Test Mode with the 923C Reaction of the CPUs 8 3 Set DIL switch S1.3 from Off to On (the following table shows the DIL switches as delivered; see also Figure 6-2). DIL S. S1.1 S1.2 S1.3 S1.4 S1.5 S1.6 on off x x x x x x Effect - - Test mode No. of occupied CPU slots = 2 No. of occupied CPU slots = 3 No. of occupied CPU slots = 4 When the coordinator mode switch is set from STOP to TEST, the CPUs can be started individually. There is therefore no synchronized transition to cyclic program processing. The output of signal BASP is suppressed on all CPUs, even if there is an error. If an error occurs with a CPU switched to RUN, only this one goes to the Stop state in the test mode. The error is indicated by slow flashing of the CPU's STOP LED. The error at this CPU does not affect other CPUs. If the test mode is not activated, a changeover from STOP to TEST does not result in any reaction of the CPUs. 6-14 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators 6.4 6.4.1 923A Coordinator Module (is no longer supplied) Technical Description This section contains information on the application, design and principle of operation of the 923A coordinator. Application The 923A coordinator module is intended for operation in the S5-135U/155U PLC. It is required in multiprocessor operation and has the following functions: Bus arbitration To coordinate multiprocessor operation, i.e. the simultaneous use of two to four CPUs (CPU 928B, CPU 928 or CPU 922). Communication memory for the interchange of data between CPUs via communication flags. Note The 923A coordinator module cannot be used in multiprocessor operation if a CPU 948 is fitted in the 135U/155U PLC. If you execute global memory access in multiprocessor operation (I/O area with addresses 0000H-EFFFH) with the CPU 928B and/or the CPU 928, you must use the COR 923C as the coordinator. Design The COR 923A is designed as a plug-in PCB of double Eurocard format. Two 48-way Series 2 blade connectors serve to connect the PCB to the S5 bus in the subrack. The front plate width is 1 1/3 standard plug-in stations. A three-position mode switch is fitted in the front plate for operator functions. System Manual C79000-G8576-C199-07 6-15 Multiprocessor Operation/Coordinators Principle of Operation Bus arbitration The COR 923A cyclically allocates a bus enable signal to each of the two to four CPUs in the S5-135U/155U PLC. Only during this time can the relevant CPU utilize the common S5 bus. The assignment of bus enable signals takes place in time-division multiplex operation. On the COR 923A, you set the number of CPUs with jumpers. The enable time for access to the S5 bus is preset at 2 ms for all CPUs. If the bus enable signal has been emitted by the coordinator for a CPU, this CPU can extend the enable time with the bus lock signal. However, the user has no influence on this. The bus enable assignment sequence begins with CPU 1 after the Reset signal is removed by the power supply, and enables the CPUs in the following order according to the preset number of CPUs: CPU 1, CPU 2, CPU 3, CPU 4, CPU 1, CPU 2 etc. (see Figure 6-5) Bus Enable for: CPU1 2 s CPU2 CPU3 2 s + Bus Lock CPU4 Bus Lock Reset CPUs in Operation Time Figure 6-5 Timing Sequences of the Bus Signals Communication memory The communication memory comprises a central battery-backed RAM in the PLC. It has two areas: the communication flags and the semaphores. The communication flags on the COR 923A allow the cyclic interchange of data between the CPUs. The semaphores are mainly used to coordinate the exchange of data in the I/O area. Please consult the Programming Guides of the CPUs to program these functions. 6-16 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators 6.4.2 Settings on the Coordinator User Control A three-stage mode switch on the front plate serves for user control; it has the settings RUN, STOP and TEST. The functions of the mode switch and its use are explained in Sections 6.2 and 6.3.

Application The 923C coordinator module can be used in the S5-135U/155U programmable controller and in the EU S5-185U expansion unit. There are three main task areas which are, to some extent, independent: Bus arbitration (only in the central controller) To coordinate multiprocessor operation, i.e. the simultaneous use of two to four CPUs (CPU 948, CPU 928B, CPU 928, CPU 922). Communication memory (only in the central controller) For the interchange of data between CPUs via communication flags and data blocks. Central programmer connection (PG MUX) For the programming and startup of up to 8 modules via one PG connection. To program a programmable controller via the SINEC H1 or SINEC L1/L2 bus, connect the SINEC CP to the PG connection of the COR C using the 725 cable ("swing" cable). 6-18 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators Design The COR 923C is designed as a plug-in PCB in double Eurocard format. Two 48-way Series 2 blade connectors serve to connect the module to the S5 bus in the subrack. The front plate width is 1 1/3 standard plug-in stations. A mode switch with three settings is fitted in the front plate for other operator functions. Faults are indicated by five small red LEDs. There is a recess with cover in the upper third of the front plate. By removing the cover, you can operate the DIL switches to set parameters for the module. You can connect the COR 923C via a 15-pin front connector to a programmer, OP, operator control panel or the CP 530 and CP 143. Principle of Operation The COR 923C cyclically allocates a bus enable signal to each of the two to four CPUs in the S5-135U/155U PLC. Only during this time can the relevant CPU utilize the common S5 bus. The assignment of bus enable signals takes place in time-division multiplex operation. On the COR 923C, you set the number of CPUs with DIL switches. The enable time for access to the S5 bus is preset at 2 ms for all CPUs. If the bus enable signal has been emitted by the coordinator for a CPU, this CPU can extend the enable time with the bus lock signal. However, the user has no influence on this. The bus enable assignment sequence begins with CPU 1 after the Reset signal is removed by the power supply, and enables the CPUs in the following order according to the preset number of CPUs: CPU 1, CPU 2, CPU 3, CPU 4, CPU 1, CPU 2 etc. (see Figure 6-7) System Manual C79000-G8576-C199-07 6-19 Multiprocessor Operation/Coordinators Bus Enable for: CPU1 2s CPU2 CPU3 2s + Bus Lock CPU4 Bus Lock Reset CPUs in Operation Time Figure 6-7 Timing Sequences of the Bus Control Signals Monitoring for continuous bus assignment The bus lock signal can only be emitted by the CPU which has already received a bus enable signal from the COR 923C. The bus enable time is extended by the duration of the bus lock signal for the CPU (see Figure 6-7). The factory setting for monitoring of the bus lock signal is 2 ms. If the signal remains active for a longer duration, the COR 923C emits a signal which results in a Stop of all CPUs. The CPU which emitted the bus lock signal for too long a duration, is marked by the CPU in a readable register under address FEFFH (fault register, see Figure 6-8). The assigned BUS FAULT LED in the front plate of the COR 923C lights up. The register is cleared and the LED goes off again when the signal which led to the Stop state becomes inactive. Communication memory The communication memory comprises a central battery-backed RAM in the PLC. It has three areas: 1) the communication flags (256 bytes), 2) the semaphores (32), and 3) four memory pages. The communication flags are located in memory area F200H to F2FFH. The communication flags enable the cyclic interchange of small volumes of data between the CPUs in the S5-135U/155U PLC. The four memory pages serve for the exchange of data blocks between CPUs. Please consult the Programming Guides of the CPUs to program these two functions. 6-20 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators The semaphores are used to coordinate the CPUs for access to the same I/O address (see Programming Guides, operations SES and SEF).

The register is an 8-bit register which is written to under address FEFFH. It cannot be read out. The page memory contains four pages of 1 Kbyte. An identification number is assigned to each page. These are the numbers 252, 253, 254 and 255. These numbers are permanently set on the COR 923C and cannot be changed. You must not use these numbers on other modules (CP, IP) in the same PLC otherwise double addressing will occur. When the supply voltage is switched on, the vector register is cleared. The vector register then has the number 0H. The transfer of data to and from this memory is implemented with special functions of the CPU. You can find these functions in the appropriate Programming Guides. PG Multiplexer System Manual C79000-G8576-C199-07 The PG interface of the COR 923C can be switched over to eight different serial interfaces via the path selection of the PG software. The multiplex interfaces have TTL level and are wired to the other modules via the backplane connector and backplane. 6-21 Multiprocessor Operation/Coordinators Selection Method for the Serial Interfaces Station numbers are assigned to all the modules to be served by the multiplexer in the unit. These numbers must be within the range 1 to 31 (decimal). You set the lowest of these numbers, the base address, with DIL switch S2 in binary code. The maximum of eight numbers are allocated to the slots of the PLC (see following table). All eight numbers or slots are assigned to switch S3: the lowest number to switch S3.1, and the highest number to switch S3.8. The setting of station numbers and the base address are described in more detail in Section 6.5.2.

Note For a module operated via the multiplexer, the front connector of the PG interface of the CPU must not be plugged in. With CPUs 948 and 928B, this only applies to the integrated PG interface SI 1. 6-22 System Manual C79000-G8576-C199-07 Multiprocessor Operation/Coordinators 6.5.2 Settings on the Coordinator Indicators and Controls Shown in Figure 6-9 are all the indicators and controls on the front plate of the COR 923C.

Coordination Section in operation out of operation All jumpers of EP 61 closed All jumpers of EP 61 open 8 1 9 16 EP 61 When the unit is delivered, all jumpers are closed. Fault Register The fault register is an 8-bit register and is readable by the CPU under address FEFFH. The register is written to by the bus monitor in the event of a bus error. Each CPU is assigned one bit of the fault register which is set to 1 in the event of an error. The register is cleared each time the Stop signal becomes inactive. 7 4 Not assigned 3 2 1 0 Fault register FEFFH Bit = 1: Bus error from CPU 1 Bit = 2: Bus error from CPU 2 Bit = 3: Bus error from CPU 3 Bit = 4: Bus error from CPU 4 The fault register can be read by all CPUs, allowing central functions to be initiated. Note The fault register and the page register are at address FEFFH (FFEFFH with the CPU 948). The page register is addressed by writing to FEFFH, and the fault register is addressed by reading out FEFFH.

Interface modules in the central controller are known as EU interface modules; those inserted in an EU are known as CC interface modules. This chapter describes the EU interface modules: IM 300-3, IM 300-5, IM 301-3, IM 301-5 and IM 304 as well as the CC interface modules: IM 312-3, IM 312-5, IM 310 and IM 314 Other IMs such as the IM 307-IM 317 and the IM 308-IM 318 are described in separate manuals (see Catalog ST 54.1). The IM 306 CC interface module is described in the S5-115U PLC manual. A general overview of the applications of individual IMs can be found in Chapter 2: "Centralized and Distributed Configuration of a Programmable Controller."

The EUs are supplied with operating voltage via the IMs. Any free connections on the IM 300-5 and the last IM 312-5 require no terminator. Note The maximum permissible current over each connection of the IM 300-5CA11 is 5 A. Connecting the EU 183U, EU 185U You can connect up to four EUs to each IM 300-3. The last IM 312-3 requires a terminator. Connecting the ER 701-1 You can connect up to three ERs to each IM 300-5L (-5LB11). The ERs are supplied with operating voltage via the IMs. Note The maximum permissible current over each connection of the IM 300-5LB11 is 2 A. The connection of central controller and expansion unit to the IM 300-5LB11 is provided exclusively by the 705-0 connecting cable. It is available in two lengths: 0.5 m and 1.5 m (refer to the ordering information for order numbers). Addressing When the IM 300s are used in the S5-135U/155U PLC, the input/output modules can be addressed in the normal (P) and extended (O) areas. You may only set module addresses in the EU which are not used in the CC. This applies to both areas.

You can also use the IM 304 and IM 314 to connect I/O modules to a CC in a distributed arrangement via the EU 183U ER 701-2 expansion units. Line Length You can connect up to two-times four EUs in a distributed arrangement via one IM 304. If you utilize the 721 connecting cable, the total line length from the CC to the last EU may be 600 m per run. You can connect additional EUs in a centralized arrangement to the distributed EUs. You can insert up to four IM 304s in one CC. The IM 304 EU interface module is complemented by the IM 314 CC interface module. In fault-tolerant systems, you must use the IM 314R CC interface module together with the IM 304 (refer to the S5-155H manual).

Technical specifications which are common to all modules are given in Section 8.3. The special technical specifications for all modules can be found in Section 8.4. I/O Modules 8-2 Digital input and digital output modules are I/O modules which allow the processing of widely differing process signals with the S5-135U/155U programmable controller. They can also be used via an adapter casing in the S5-115U PLC. System Manual C79000-G8576-C199-07 Digital Input/Output Modules Digital Input Modules A digital input module converts the process signals to the internal signal level in the module. Interference is suppressed by the input circuitry, and the logic states at the inputs are indicated with LEDs on the front strip of the module. With most digital input modules (except the 420), the signals are isolated from the central ground point when received. Inputs relating to the same group are isolated from inputs of another group, but not from each other. Digital Output Modules The control signals processed in the PLC are output via digital output modules at a signal level suitable for the actuator, for example contactor, solenoid valve, etc. For the voltages and currents required in the process, modules with appropriate output circuitry are available. With most digital output modules (except the 441), the signals are isolated from the central ground point when relayed to the outputs. Outputs relating to the same group are isolated from outputs of another group, but not from each other. BASP If a digital output module receives a "command output inhibit" (BASP, cf. Programming Guide and Chapter 4) from the CPU, the outputs are set to zero. When the supply voltage of the central controller or expansion unit has been switched on or when the CPU is at STOP, the outputs are set to zero. Signal Output, Short-Circuit Detection Signal output H+ on digital output modules for direct voltage emits a signal when a short-circuit to ground (L-) or overcurrent has been detected at one or more outputs currently at logic 1. Only short-circuits which are effective for more than 0.5 to 1 s are detected. Short-circuits are only detected at connected outputs. The signal outputs are decoupled by diodes. Up to 16 outputs can be connected in parallel. Ensure that isolation is not defeated by the parallel connection of outputs. To ensure functioning of the signal output, you must connect terminal 1L+ to 24 V on the 441, 451 and 454 modules. On the 453 and 457 modules, the floating signal output must be powered separately. System Manual C79000-G8576-C199-07 8-3 Digital Input/Output Modules 8.1.1 Design The modules are designed as plug-in PCBs for central controllers and expansion units with backplane connector and with a blade connector to accept a plug-in front connector. The front connector has screw or crimp terminals and is available separately; you can connect the process signal lines to it directly. LED Indicators Fitted to each module is a strip with green LEDs to indicate the logic states of inputs or outputs. The LEDs are arranged in bytes and marked bit 0 to 7. Output modules for direct voltage additionally have red LEDs to indicate short-circuits between output lines and ground (L-) within a group. Output modules for alternating voltage have red LEDs to indicate a fuse failure. Addressing Switch Fitted on each module is an addressing switch with six, seven or eight rockers to set the module address. The modules are protected on both sides by covers. Addressing Switch Blade Connector Front Connector LEDs Figure 8-1 8-4 Digital Input Module System Manual C79000-G8576-C199-07 Digital Input/Output Modules 8.1.2 Function of the Enable Inputs The digital input/output modules have an enable circuit. You can use the enable inputs to implement electrical interlocks for certain modules or switch off individual modules, whilst the PLC is in operation. This means that: the module can no longer be addressed by the user program. all outputs of digital output modules are set to zero. With an Active Enable Input Modules which are switched off can be removed or inserted during operation. If this is not necessary, operate the module with the enable input switched off. On digital input/output modules with DC voltage inputs or outputs, the enable circuit requires that enable inputs F+ and F- be wired in the front connector. Enabling is achieved by applying an external voltage to inputs F+/F-. Modules for AC voltage have a wire jumper in the front connector. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the wire jumper in the front connector is removed; the module is switched off and can no longer be addressed by the user program. When the front connector is swivelled away, i.e. the voltage is removed from the enable inputs, a timeout (QVZ) occurs at the CPU (see the Programming Guide for the particular CPU). Apart from the 6ES5 458-4UC11 digital output module, all digital input/output modules additionally offer the facility for changing the enable mode. The modules have a jumper accessible from above in the vicinity of the addressing switch (see Figure 8-2). Enable Jumper Figure 8-2 Location of the Enable Jumper Jumper inserted: Jumper open: System Manual C79000-G8576-C199-07 Enable input (F+/F-) active (factory setting) Enable input (F+/F-) switched off 8-5 Digital Input/Output Modules With Enable Input Switched Off If removal and insertion of modules during operation is not required, you must remove the plug-in jumper for changeover of the enable mode. Wiring of the enable inputs (F+/F-) can then be dispensed with. Examples of Functioning of the Enable Inputs Almost power-free shutdown of individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. The load voltage of each individual module can be monitored without additional circuitry. Any reactions to failure of the load voltage can be programmed in the QVZ (timeout) organization block. You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as voltage is applied to the CC/EU. You should observe the following instructions for switching off PLCs and equipment for supplying power to the enable inputs: 24 V supply for CC/EU and I/Os a) I/O Modules Battery b) F+ CC/EU 24V Power Supply 24 V DC L+ L+ Enable supply from: a) Battery b) Terminals for 24 V on the front plate of the power supply 8-6 System Manual C79000-G8576-C199-07 Digital Input/Output Modules Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the power supply is used without an additional capacitor and common shutdown. 230 V AC supply for CC/EU and load power supply b) a) I/O Modules -951 Battery c) F+ CC/EU L+ Power Supply L+ 230V AC Load Power Supply 24V Enable supply from: a) 6ES5 951-4LB11 load power supply b) Battery c) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 F per 10 A of load current. Other units (load power supply for 20 or 40 A) which do not meet this condition can be adapted to this requirement by connecting a 10000 F/40 V capacitor in parallel.

You can operate the module in the following modes: Modes without process alarm ("normal" digital input module) with initiation of a process alarm via interrupt with initiation of a process alarm via IB 0 (only in conjunction with CPU 948) To operate the module with process alarm via IB 0, you must address it in the normal (P) area from byte 128 because the automatic updating of the process image might acknowledge a process alarm without the system program having detected and interpreted this alarm; only modules addressed in the normal (P) area can initiate a process alarm via IB 0. Reaction Time The time for reaction of the module to a process alarm is mainly determined by the input circuitry. You can set the reaction time to one of the values 0.3 ms, 1 ms or 3 ms with switch S5. Note that the filtering effect decreases with shorter reaction times, and interference may be received as useful signals (effect of the line length, see the Technical Specifications). Operation without Process Alarm To operate the module without process alarm, you can insert it at any slot for I/O modules and address it in the entire I/O area. If you address it in the area PB/PY 0 to PB/PY 124, it will be within the automatic updating of the process image. Settings on the Module Make the following settings on the module to operate it without process alarm: Step Action 1 2 Open jumpers X3 and X4 Set switch rows S1 and S2 to Off S2 S1 Figure 8-3 0 IR-A 0 Bit 0 1 IR-B 1 Bit 1 2 IR-C 2 Bit 2 3 IR-D 3 Bit 3 4 IR-E 4 Bit 4 5 IR-F 5 Bit 5 :OFF 6 IR-G 6 Bit 6 :ON 7 INT 7 Bit 7 Switch Settings for Operation without Process Alarm The setting for switch row S3 is arbitrary in this mode. 8-8 System Manual C79000-G8576-C199-07 Digital Input/Output Modules Operation with Process Alarm via Interrupt To operate the 432 digital input module with process alarm via an interrupt, you must either operate it in the CC where only certain slots have interrupt lines (see Chapter 4), or in an interrupt-capable EU connected to the CC with IM 307 - IM 317 interfacing (see also the IM 307 - IM 317 manual). In the CC, you may only operate the module in this mode at slots with an interrupt line (interrupt source). So that the module can initiate a process alarm for a change of logic state, the alarm must be processed by an alarm routine (alarm OB) in the user program, with automatic acknowledgement of the alarm. To avoid loss of an alarm, it must not be possible for the alarm OB to be interrupted by process alarms. The CPU must process the process alarms with level triggering (see Programming Guide of the CPU). Scanning the Process Inputs Example: Program the following operations in the corresponding alarm OB: L T L T PW132 FW10 PW134 FW12 (load I/O word) (transfer flag word) etc. Only the flag word may be accessed during the cyclic program. Accessing the I/O bytes in the process image will result in alarm loss. Addressing of the module must therefore be above address 127. Double accessing of I/O bytes, even from different CPUs, is not permissible (alarm loss). The four I/O bytes of a module must be scanned successively and in ascending order. The scanning of byte n inhibits all input circuits of the module, and the scanning of byte (n + 3) enables them again. Settings on the Module System Manual C79000-G8576-C199-07 Make the following settings on the module to operate it with a process alarm via interrupt: Step Action 1 Open jumper X4 and close jumper X3. 2 Set the interrupt line at switch row S1: the switch relating to the desired interrupt line should be set to On. Set all other switches to Off. You can set the same interrupt line on several modules. 3 Set switch row S2 to Off. 4 Set switch row S3 to choose whether the interrupt is to be initiated with a positive-going (leading) or negative-going (trailing) edge. The setting of a pair of switches applies to an entire byte. 8-9 Digital Input/Output Modules S1 : OFF : ON 0 1 2 3 4 5 6 7 S3 S2 IR-A IR-B IR-C IR-D IR-E IR-F IR-G INT 0 1 2 3 4 5 6 7 Bit 0 Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Bit 7 0 1 2 3 4 5 6 7 } } } } Byte 3 Byte 2 Byte 1 Byte 0 Process Interrupt via IR-C Byte 0: Positive-Going Edge Byte 1: Negative-Going Edge Byte 2: Both Edges Byte 3: No Process Interrupt Figure 8-4 Switch Settings for Operation with Process Alarm via Interrupt (Example) Operation with Process Alarm via IB 0 In this mode, a process alarm is initiated via input byte IB 0. This mode is only possible in conjunction with a CPU 948 in single-processor operation. To operate the 432 digital input module with process alarm via IB 0, you can insert it at any I/O slot. When you use the module in the CC, you must not set any other input module to address 0 (i.e. neither in the normal (P) nor in the extended (O) area). If you use the module in an EU which is addressed in the normal area, you must not set any other input module in the EU to address 0 in the normal area. So that the module can initiate a process alarm for a change of logic state, the alarm must be processed by an alarm routine (alarm OB) in the user program, with automatic acknowledgement of the alarm. To avoid loss of an alarm, it must not be possible for the alarm OB to be interrupted by process alarms. The CPU must process the process alarms with level triggering (see Programming Guide of the CPU). Scanning the Process Inputs Example: Program the following in the alarm OB which you have preset with byte IB 0 and switch S2: L T L T 8-10 PW128 FW0 PW130 FW2 (load I/O word) (transfer flag word) etc. System Manual C79000-G8576-C199-07 Digital Input/Output Modules Only the flag word (FW) may be accessed during the cyclic program. Accessing the I/O bytes in the process image will result in alarm loss. Addressing of the module must therefore be above address 127. Double accessing of I/O bytes, even from different CPUs, is not permissible (alarm loss). The four I/O bytes of a module must be scanned successively and in ascending order. The scanning of byte n inhibits the input circuit of the module, and the scanning of byte (n + 3) enables them again. Settings on the Module Make the following settings on the module to operate it with a process alarm via IB 0: Step Action 1 Insert jumpers X3 and X4 2 Set switch row S1 to Off. 3 Set bit 0 on switch row S2 to On, and all other switches to Off. 4 Set switch row S3 to choose whether the interrupt is to be i nitiated with a positive-going (leading) or negative-going (trailing) edge.

The modules must all be inserted in the CC or in the same EU for error-free acknowledgement of address 0. Each module reserves one bit in IB 0. You must set one module to bit 0 on switch row S2; on the other modules you must remove jumper X3 and set one of the other bits 2 to 8. The module you have set to bit 0 is known as the master, and the other modules are slaves. On the master module, you must additionally set the number of slave modules on switch row S2. Refer to the labeling on the module cover. Using the 432 Digital Input Module with other AlarmGenerating Modules You can also use the 432 digital input module with process alarm together with other alarm-generating modules. To operate the module with process alarm via interrupt, you must observe the following: If a process alarm is generated via an interrupt, the I/O words of all 432 digital input modules involved in this process alarm must be read in the alarm-processing OB; with IPs, the process alarms must be acknowledged (refer to the manuals of the IPs). The modules must be inserted at interrupt-capable slots (see Chapter 4). To operate the module with process alarm via IB 0, you must observe the following: You may use up to eight alarm-generating modules. The modules must all be inserted in the CC or all in the same EU. You must operate the 432 module as the master. If you use two or more 432 digital input modules with other alarm-generating modules, you must operate one 432 as the master and all others as slaves. 8.1.4 Special Features of the DI/DQ 482 The DI/DQ 482 digital input/output module (6ES5482-4UA11) is a process signal I/O module which allows the processing of process signals in conjunction with the IP 257, with the S5-135U/155U PLC and the EU 185U (see the IP 257 manual). The DI/DQ 482 (6ES5482-4UA20) has an identical functionality, but not an interface which allows a connection to the IP257. The following section describes the operation of the DI/DQ 482 without IP 257. The DI/DQ 482 has 32 channels which are jointly isolated, i.e. there is no subdivision into groups in the module. Channels 0.0 to 0.7 are digital outputs, channels 2.0 to 3.7 are digital inputs; channels 1.0 to 1.7 can be optionally and individually operated as inputs or outputs. 8-12 System Manual C79000-G8576-C199-07 Digital Input/Output Modules Changeover of the I/O byte The operation of channels 1.0 to 1.7 as inputs or outputs merely depends on the user program. You define the byte as an input with a read access to the DI/DQ; you define the byte as an output with a write access. The double-function of the byte also allows the output byte to be read out. Unused channels should not be wired nor addressed by program. When these channels are used as inputs, it should be noted that the corresponding bits in the output register remain at logic 0. This resetting of output registers is executed automatically after power-up of the PLC or EU. Note When at least one of channels 1.0 to 1.7 is operated as an input, the connected sensors and the 1L+ terminal must have the same power supply. If this is not the case, the input voltage acts on the 1L+ terminal. The resultant supply to the output amplifiers of channels 0.0 to 1.7 causes currents to be drawn via the wired input terminal; these currents may assume different values, depending on the control states of the outputs. With the DI/DQ 482 (6ES5482-4UA11) you must set slide switch S2 to setting 1 for operation without the IP 257. Slide Switch S2 Local Bus Interface Figure 8-6 System Manual C79000-G8576-C199-07 Slide Switch S2 on the DI/DQ 482 8-13 Digital Input/Output Modules 8.2 Installation and Startup This section describes how to prepare digital input/output modules for installation, and how to install and wire them. 8.2.1 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The address of the digital input modules (input bytes IB 0 to 255 or 252 for the DI/DQ 482) and digital output modules (output bytes QB 0 to 255 or 252 for the DI/DQ 482) is the sum of the binary significances established by depressing the individual rockers in the On setting (). The modules are addressed by the STEP 5 program under their parameters (byte address). Labeling Field You can affix the adhesive label with the desired module address on a labeling field under the addressing switch. Suitable labels are supplied with the CC. The switch rockers with which the module address (IB n or QB n) is specified as a decimal number, are marked by dots on the label. Do not use a pencil to set the addressing switch. 8-14 System Manual C79000-G8576-C199-07 Digital Input/Output Modules On Setting (Switch Pressed) Addressing Switch Labeling Field for the Module Address and Marked Switch Settings Figure 8-7 2 1 Address Bit ADB0 Binary Significance of the Address Bit ADB1 16 32 8 4 ADB2 ADB3 ADB4 ADB5 ADB6 ADB7 128 64 Address (Decimal) Labeling of the Addressing Switch (Extract from Module Labeling) The address byte under which the module is referenced by the STEP 5 program is independent of the slot. Start Address For modules with 16 or 32 inputs or outputs, i.e. 2 or 4 bytes, only the lowest address (start address) is set for the first byte. The addresses of the following bytes of the same module are decoded on the module. If, for example, the address 20 is set for a 16-bit module (2 bytes), the following address 21 is decoded internally and is no longer available. The next free address would be 22. For a 32-bit module (4 bytes) with start address 20, addresses 21, 22 and 23 would be decoded internally. The next free address would be 24. Addresses already assigned must not be set again. However, digital input and output modules may be given the same address because they are referenced by different commands in the user program.

Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install a digital input/output module as follows: 8-18 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90 at the lower end of the module. 4 Engage the front connector on the support pin of the module and swivel it up. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (for example 230 V AC front connector on 24 V DC modules). 5 Tighten the screw in the upper part of the front connector. System Manual C79000-G8576-C199-07 Digital Input/Output Modules Remove a digital input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module, if necessary, by rotating the locking pin by 90o. You can pull the module out of the subrack with a grip which swivels outwards. 6 Module 1 Front Connector 5 3 Figure 8-8 1 2 3 4 5 6 Wiring System Manual C79000-G8576-C199-07 2 4 Support Mount Support Pin Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0100 and 0160 to carry out the wiring of the supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules.

Front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are provided to connect the signal lines (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductors to facilitate handling of the front connector. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see Ordering Information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length according to DIN 46228.

Connection of Outputs in Parallel and Switching On the Load via a Contact ! Digital Output Modules for DC Voltage Caution The parallel connection of outputs to increase the load is not permissible. Outputs of modules with the same load voltage supply may be connected in parallel without additional circuitry. An external diode must be fitted to the output lines of modules fed from different load voltage supplies (exception: 453, 457). In the case of different logic states of the two outputs, the maximum permissible output current corresponds to that of the lower stage. The contact (for ex. for manual operation) is connected to one of the two L+.

Note that when inputs or outputs from two isolated groups are connected to one power supply unit, isolation between the groups is defeated. 8.2.6 Short-Circuit Protection and Fusing With digital output modules for DC voltage, fuses are provided on the module, in addition to the electronic short-circuit protection, for the wiring cables and to protect the module. The fuses also provide protection against reversal of supply voltage connections and can only be replaced at the factory. The electronic short-circuit protection guaranteed in the technical specifications applies to a resistance which is lower than the specified, maximum permissible line resistance. In the event of a short-circuit, two to three-times the rated output current flows briefly at the output before the switched electronic short-circuit protection becomes effective. When selecting the load power supply units, therefore, allow for the increased short-circuit current as well as all connected output loads (observe the coincidence factor). With unregulated load power supplies, this overcurrent is generally ensured. With regulated load power supplies, especially at low output power levels (up to 20 A), you must allow for a corresponding overcurrent. 8-24 System Manual C79000-G8576-C199-07 Digital Input/Output Modules 8.2.7 Quenching for Inductive Loads Note Digital output modules have integrated circuits on the module to quench inductive loads (refer to the technical specifications of the output modules). Exception: The 458 digital output module allows the switching of inductive loads with contact protection submodules. The integrated circuits on the modules for quenching inductive loads are disabled if the load circuits are interrupted, either operationally by contacts and switches, or by fuses in the event of a fault. This can result in excessive, inductive breaking voltages which put fault-free operation at risk. You can prevent this with additional, external quenching circuitry for the inductive loads.

When selecting or designing the quenching circuitry, the technical specifications for the digital output should be taken into account. These are: The permissible overvoltage for the supply voltage (see Section 8.3 "Common Technical Specifications") Inductive breaking voltage of the output (see Section 8.4 "Description of Individual Modules") Switching Frequency of the Output is Higher than the Permissible Value An external quenching circuit only provides thermal relief if its quenching voltage is lower than the breaking voltage specified for the module, allowing for unfavorable supply voltage conditions. Example: 453 digital output Inductive breaking voltage L+ - 47 V (Tech. Specifications) Max. supply voltage L+ = 30 V Quenching voltage referred to L- (0 V ground) is - 17 V The quenching device must be rated at approximately 15 V and the switched load current, for example, 1 A. Disconnecting the Load Circuit A quenching device rated for the induced breaking current must be provided at the load (see Figure 8-14). The quenching voltage at the load is independent of the module. The quenching devices must also ensure that the overvoltages at the switch and in the wiring do not exceed the disturbance voltage and voltage hazard limits permissible to VDE/IEC. Disconnecting the Supply Line L+ and L The following applies to digital outputs for DC voltage: In general, load power supplies should be switched on the primary side to utilize the low-resistance secondary winding and smoothing capacitors of the power supply for energy compensation in the dropping of inductive loads. The load power supply switch should only be considered as a circuit breaker. Switched-Through Outputs With switched-through digital outputs and disconnection of the supply line L+, the output current is maintained during the quenching time by capacitors and the reverse voltage protection diode on the module. This severe electrical stress of the module should be avoided during operations, because it can result in a fault in the long term. 8-26 System Manual C79000-G8576-C199-07 Digital Input/Output Modules Two-Wire Switches With two-wire switches and AC voltage outputs: Disconnection of the supply voltage during operation is not permissible without additional protective circuitry. Quenching of the inductive load is achieved here via the load power supply unit or system. Since, as two-wire switches, the outputs have no L-/N (0 V ground) terminal, the inductive load cannot be quenched on the module when the supply line is disconnected. With the 453 and 457 modules using two-wire switches, the overvoltages can result in destruction of the module. If the load voltage must be switched for safety reasons, you must provide external quenching circuitry at each inductive load (see Figure 8-15). Instead, with the 453 and 457 modules using two-wire switches, you can insert a quenching device (diode) with adequate ratings after contact K from the L+ line to L-.

You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals. Addressing Switch, Mode Switches Situated on each module is an addressing switch with six rockers to set the module address. Analog input modules also have two switches on the side with eight rockers for setting the mode, and receptacles for range cards. The modules are protected by covers on both sides. Addressing Switch Blade Connector Front Connector Mode Switches Range Cards Figure 9-1 9.3.2 Analog Input Module Function of the Enable Input The 460 module has an enable circuit. You can use the enable inputs to switch off individual modules whilst the PLC is in operation. This means that: The module can no longer be addressed by the user program. Modules which are switched off can be removed or inserted during operation. If this is not necessary, operate the module with the enable input switched off. 9-4 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC. Switching Off the Enable Input The 460 module additionally offers the facility for changing the enable mode. The module has a jumper accessible from above in the vicinity of the addressing switch. When the enable jumper is inserted, you can define the behaviour of the 460 analog input module as follows: When the enable voltage and load voltage are obtained from the same load supply, a shutdown of the 24 V load voltage will result in a timeout. When the enable voltage and load voltage are obtained from different load supplies, a shutdown of the 24 V load voltage will not result in a timeout. (With the 460-4UA11/12 modules, a shutdown of the load voltage will result in a timeout.) Enable Jumper Figure 9-2 Enable Input and Enable Jumper Jumper inserted: Jumper open: Enable input (F+/F-) active (factory setting) Enable input (F+/F-) switched off Examples of functioning of the enable inputs: To switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. The load voltage of individual modules can be monitored without additional circuitry. Any reactions to failure of the load voltage can be programmed in the QVZ (timeout) organization block. System Manual C79000-G8576-C199-07 9-5 Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present. Switching off the CC You should observe the following instructions for switching off CCs and equipment for supplying power to the enable inputs. Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the load power supply is used without an additional capacitor and common shutdown. 230 V AC supply for CC/EU and load power supply b) a) -951 Battery I/O Modules c) F+ CC/EU L+ Power Supply L+ 230 V AC Load Power Supply 24V Supply for the enable inputs from: a) 6ES5 951-4LB11 load power supply b) Battery c) Terminals for 24 V on the front plate of the power supply 9-6 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) Battery b) I/O Modules F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 F per 10 A of load current. Other units which do not meet this condition can be adapted to this requirement by connecting a 10000 F / 40 V capacitor in parallel.

You can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors). Broken Wire Signal To monitor the sensors connected to the inputs, you can use the 6ES5 498-1AA11 range card (through-connection card) to implement the "broken wire detection" mode. You can activate broken wire detection for 4 or 8 inputs. Each time the input value is about to be encoded, a constant current is briefly (1.6 ms) switched to the input terminals and the resultant current is checked for a limit value. If a digital voltmeter is used to measure the signal at the input, these current pulses may appear to indicate fluctuation of the signal. The encoded value, however, is not affected. Switching the Tripping Current to the Inactive State If these apparent fluctuations of the signal are disturbing, for example, during startup, you can switch the tripping current to the inactive state on the 460 analog input module: apply + 24 V to pin 24 of the front connector, and 0 V to L-. You must additionally set the mode switch to "without broken wire detection." In the event of open-circuit of the sensor or its line, the voltage exceeds the limit and a broken wire is indicated (bit 1 in data byte 1). The analog-to-digital converter encodes the value 0. A broken wire signal is only useful when the 6ES5 498-1AA11 through-connection card is used. With all other measurement cards, a broken wire signal will result in incorrect reactions. Further details relating to the broken wire signal can be found in Section 9.3.12. Measuring Range Exceeded If the measuring range is exceeded, the overflow bit (bit 20 of the low byte) is set. Cyclic Sampling You have a choice of the cyclic sampling and selective sampling modes. In the cyclic sampling mode, the module continuously encodes all measured values. The digitized measured values are stored under the channel-related address on the module (the high byte under this address, and the low byte under the next higher address). The measured values can then be read by the module at any time without waiting. When you operate the module in this mode, you can set a module address from 0 to 255. 9-8 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Selective Sampling In the selective sampling mode, a measured value is encoded on the central initiative of the CPU. At the start of conversion, the module must be addressed once with a write operation (T PW) by the user program. An active bit (T = 1) is set during encoding. With the transition to T = 0, the measured value becomes valid. With non-constant cycle times, there may be non-periodic measured value aquisition. If you operate the module in this mode, you must set a module address from 128 to 255. You can also use the address range from 0 to 127 for selective sampling after appropriate programming in DB 1 of the user program. Time-Controlled Program Processing Another method is that of time-controlled program processing. With this method, certain program segments (e.g. FB 13) are automatically inserted into program processing at the 100 ms rate by a time-controlled block (OB 13). A constant timebase is thus achieved.

BASP (Output Inhibit) The BASP signal is not interpreted by the 460 analog input module. System Manual C79000-G8576-C199-07 9-9 Analog Input/Output Modules 9.3.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting ( ). One data word = two data bytes is required to process an input or an output. A module with 16 inputs therefore reserves 32 byte addresses, and a module with 8 inputs or outputs reserves 16 byte addresses. Labeling Field You can affix the adhesive label with the desired module address on a free labeling field under the addressing switch. The switch rockers to be set for the module address specified as a decimal number (address bit ADB) are marked by dots on the label. Press the individual rockers of the addressing switch downwards with a ballpoint pen or similar object, but not a pencil. Note Ensure that all the switches are operated properly (meaning pressed past the latching point). On Setting (Switch Pressed) Addressing Switch Free Field for Label with Module Address and marked Switch Settngs ADB1 ADB0 8 16 32 4 2 1 ADB3 ADB2 ADB7 ADB6 ADB5 ADB4 128 64 Address (Decimal) Decimal Signification of the Address Bit Address Bit ADB0 and ADB1 are not assigned ADB2 is not connected Figure 9-3 9-10 Labeling of the Addressing Switch System Manual C79000-G8576-C199-07 Analog Input/Output Modules The address under which the module is referenced by the STEP 5 program is independent of the slot. Start Address, Subaddress For analog input and analog output modules (8 inputs) only the lowest address (start address) is set. Other addresses (subaddresses) are decoded on the module. Note The start address of the analog module must be a multiple of the double channel number. 4 channels : 0, 8, 16, 24, ... 248 8 channels : 0, 16, 32, 48, ... 240 If one of the inputs or outputs (Channel 0 to 7) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the input or output, based on the start address of the module, is given by: Start address + 2 x channel no. = subaddress Example: Analog input module with 8 inputs The address is the sum of the significances set with the individual coding switches. 160 = 128 + 32 = 27 + 25 On Setting (Switch Pressed) ADB1 ADB0 8 16 4 2 1 ADB3 ADB2 64 32 ADB7 ADB6 ADB5 ADB4 128 IB 160 A module with 8 inputs (Channel 0 to 7) and start address 160 reserves the address range from 160 to address 160 + 7 x 2 = 174 In this example, the next free address for another module is 176. Addresses already assigned must not be set again. System Manual C79000-G8576-C199-07 9-11 Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. For selective sampling, you can also use the address range from 0 to 127 after appropriate programming in DB 1 of the user program. Example: On an analog input module with start address 160 (IB 160 = input byte 160), input channel 3 is to be scanned by the program. 9-12 Step Action 1 Affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. ADB 5 and ADB 7 are marked on the label. 2 Press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. Set the other rockers to the opposite setting. This way sets the start address of the module. ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160 3 Enter the address 160 + 3 x 2 = 166 in the program for input channel 3. System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.3.5 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install an analog input/output module as follows: System Manual C79000-G8576-C199-07 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90o at the lower end of the module. It must no longer be possible to pull the module forwards. 4 Engage the front connector on the support pin of the module. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (e.g. front connectors with 115/230 V AC wiring cannot be plugged into analog modules). 5 Tighten the screw in the upper part of the front connector. 9-13 Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. If the enable input is active, power is removed from the outputs and the module is isolated from the S5 bus. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module by rotating the locking pin by 90o at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards. 6 Module 1 Front Connector Support Mount 5 Support Pin 4 2 3 Figure 9-4 1 2 3 4 5 6 Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0110 and 0160 to carry out the wiring of supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules.

Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see Ordering Information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length to DIN 46228. The maximum terminal area is 2 x 2.5 mm2. Terminal T Type Connector T Type 6ES 497- Cross-Section Max. N off No. Signal or Supply Aux.

Caution Only extra-low voltage 60 V DC with safety separation from system voltage may be used for the 24 V DC supply and for the 24 V DC input signals. Safety separation can be implemented to the requirements of, amongst other sources, VDE 0100 Part 410/HD 384-4-41/IEC 60364-4-41 (as functional extra-low voltage with safety separation) or VDE 0805/EN 60950/IEC 60950 (as safety extra-low voltage SELV) or VDE 0106 Part 101. System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.3.8 Connection of Sensors Observe the following information when connecting the sensors. Connection of Current or Voltage Sensors With isolated sensors, it is possible for the measuring circuit to develop a potential with respect to ground which exceeds the permissible potential difference UCM (see maximum values of the individual modules). To prevent this, you must connect the negative potential of the sensor to the reference potential of the module (0 V bus). Example: Temperature measurement on a busbar with insulated thermocouples Equipotential Bonding In the worst case, the measuring circuit can develop an excessively high potential on account of a static charge or contact resistances. This must be prevented with an equipotential bonding conductor. The permissible potential difference (UCM) between the inputs and the 0 V bus must not be exceeded. Depending on the system or type of sensor, the potential difference must be kept in the permissible region with epuipotential bonding.

A 460 analog input module with isolated input is used (UCM = 60 V AC/75 V DC).

Measurement If the room temperature fluctuations at the reference point (for example, in the terminal box) affect the measurement result and you do not wish to use a thermostat, you can compensate for the effect of temperature on the reference point with a compensating box. Between - 10 and + 70 oC, it compensates for the change in thermal e.m.f. caused by temperature deviation (compensating box, see Catalog MP 19). Ensure that the compensating box has thermal contact with the terminals. If the compensating box is aligned at 20 oC, this must be taken into account in temperature evaluation (20 oC measuring point temperature = 0 mV). Pins 22 and 23 are extended on analog input modules as an input for the compensating voltage. You must select a common input loop for all inputs on mode switch 2. The compensating box must be connected in a floating circuit. The power supply unit of the compensating box must have a grounded shield winding to avoid AC system interference being picked up. A separate compensating box with its special power supply unit is required for each analog input module.

If it can be ensured that the temperature does not exceed 850 oC, the input value may extend into the overrange. The resolution is then 4095 units. Unused inputs can be utilized for voltage measurements in the 500 mV range (see front connector assignments). Extended Pt 100 Range In addition to the standard Pt 100 range, there is an extended Pt 100 range on the 460 analog input module. You can select this with the mode switch. The following is printed on the cover of the module to set the Pt 100 mode: Standard range: "resistance thermometer uncompensated full range" Extended range: "resistance thermometer compensated low range" In this range, the basic resistance of the Pt 100 at 0 oC (100 ohm) is compensated for on the module. As in the standard range, the Pt 100 is fed with a constant current of 2.5 mA. Using the overrange (- 100 mV to + 100 mV), this results in a temperature range of approx. -100 C to + 100 C. This measuring range of 200 C is resolved to 8192 units with the correct sign for the temperature. One unit thus corresponds to approximately 0.025 C. If you select the extended Pt 100 range, you can use all 8 analog inputs in this range only. You should only use the 6ES5 498-1AA11 range card ( 50 mV/500 mV). 9-26 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Measured-Value Representation in the Extended Pt 100 Measuring Range (Two's Complement) Units Pt 100/ohm Temp. i oC in Byte 0 Byte 1 7 S 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 211 210 29 28 27 26 25 24 23 22 21 20 A E OV 140.0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 0 1 Overflow 4095 2049 139.99 120.01 103.74 0 51.61 0 1 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0 0 0 0 0 0 Overrange 2048 +1 0 -1 -2048 120.0 100.01 100.0 99.99 80 51.58 0.026 0 -0.026 -50.78 0 0 0 1 1 1 0 0 1 1 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 1 0 1 0 0 0 0 0 0 -2049 -4095 79.99 60.01 -50.81 1 -100.60 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0 0 0 0 0 0 Overrange 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 Overflow >4095 <-4095 60 0 0 0 0 0 0 0 0 0 0 Rated range Broken wire -4095 Arbitrary Arbitrary 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 Broken wire Ic+/Ic-2) -4095 Arbitrary Arbitrary 1 0 0 0 0 0 0 0 0 0 0 0 1 0 1 1 Broken wire Sensor Measuring line 1) 1) 2) Only with broken wire monitor activated, error bit = 1 only for faulty channel; for sensor broken wire, overflow bit = 1 for all channels On account of the Pt 100 series circuit, this bit combination always appears for all channels if the supply line is open-circuit.

If you require a representation from 0 to 2048, you must subtract 512 units by software. Please note the following: A broken wire signal cannot be emitted. Detection of the overrange can be achieved by scanning bits 29 and 211. A broken wire can be detected with currents < 3 mA. Current Limiting If you short-circuit the positive and negative terminals of the transducer when using the 6ES5 498-1AA51 range card (for a two-wire transducer), the current is limited to about 28 mA. Until the thermal current limiting circuit responds in the range card (about 3 s), a short-circuit current of approximately 250 mA flows; this sets the overflow bit for this duration at all channels.

System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.4 9.4.1 The 463 Analog Input Module Design The modules are designed as plug-in PCBs for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals. Addressing Switch, Mode Switches Situated on each module is an addressing switch with six rockers to set the module address. Analog input modules also have two switches on the side with eight rockers for setting the mode, and receptacles for range cards. The modules are protected by covers on both sides. Addressing Switch Blade Connector Front Connector Mode Switch Figure 9-12 9.4.2 Analog Input Module Function of the Enable Input The 463 module has an enable circuit. You can use the enable inputs to switch off individual modules whilst the PLC is in operation. This means that: The module can no longer be addressed by the user program. Modules which are switched off can be removed or inserted during operation. If this is not necessary, operate the module with the enable input switched off. System Manual C79000-G8576-C199-07 9-35 Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC. Switching off the Enable Input The -4Ux12 type modules additionally offer the facility for changing the enable mode. The modules have a jumper accessible from above in the vicinity of the addressing switch. Enable Jumper Figure 9-13 Enable Input and Enable Jumper Jumper inserted: Jumper open: Enable input (F+/F-) active (factory setting) Enable input (F+/F-) switched off Examples of functioning of the enable inputs: To switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. The load voltage of individual modules can be monitored without additional circuitry. Any reactions to failure of the load voltage can be programmed in the QVZ (timeout) organization block. 9-36 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present. Switching off the CC You should observe the following instructions for switching off CCs and equipment for supplying power to the enable inputs. Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the load power supply is used without an additional capacitor and common shutdown. 230 V AC supply for CC/EU and load power supply b) a) I/O Modules -951 Battery c) F+ CC/EU L+ Power Supply L+ 230 V AC Load Power Supply 24V Supply for the enable inputs from: a) 6ES5 951-4LB11 load power supply b) Battery c) Terminals for 24 V on the front plate of the power supply System Manual C79000-G8576-C199-07 9-37 Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) I/O Modules Battery b) F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 F per 10 A of load current. Other units which do not meet this condition can be adapted to this requirement by connecting a 10000 F /40 V capacitor in parallel.

The module 463-4UA12 is suitable for operation near 50 Hz systems, the module 463-4UA12 is suitable for operation near 60 Hz systems. In the subsequent module 463-UA13 the system frequency can be set by switch. Adaptation of the Measuring Range The measuring range for each channel is adapted by appropriately connecting the sensors and with jumpers in the front connector of the module (see the front connector assignments). Note The ohmic resistance of the jumper with which the measuring range is set is also measured. As the resistance of this jumper is not inconsiderable (0.5 to 0.7 ohm in relation to the measuring shunt of 50 ohm) when I/O module cables with integral connectors and subsequent wiring blocks are used, the measurement result may be corrupted accordingly. 9.4.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting ( ). One data word = two data bytes is required to process an input or an output. A module with 4 inputs therefore reserves 8 byte addresses. Labeling Field You can affix the adhesive label with the desired module address on a free labeling field under the addressing switch. The switch rockers to be set for the module address specified as a decimal number (address bit ADB) are marked by dots on the label. The unmarked switches should be switched off. Note Press the individual rockers of the addressing switch downwards with a ballpoint pen or similar object, but not a pencil. Ensure that all the switches are operated properly (meaning pressed past the latching point).

Start Address, Subaddress For analog input and analog output modules (4 inputs) only the lowest address (start address) is set. Other addresses (subaddresses) are decoded on the module. Note The start address of the analog module must be a multiple of the double channel number. 4 channels : 0, 8, 16, 24, ... 248 If one of the inputs or outputs (channel 0 to 3) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the input or output, based on the start address of the module, is given by: Start address + 2 x channel no. = subaddress 9-40 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Example: Analog input module with 4 inputs The address is the sum of the significances set with the individual coding switches. 160 = 128 + 32 = 27 + 25 On Setting (Switch Pressed) 8 16 32 4 2 1 ADB3 ADB2 ADB1 ADB0 ADB7 ADB6 ADB5 ADB4 128 64 IB 160 A module with 4 inputs (channel 0 to 3) and start address 160 reserves the address range from 160 to address 160 + 3 x 2 = 166 In this example, the next free address for another module is 168. Addresses already assigned must not be set again. Example: On an analog input module with start address 160 (IB 160 = input byte 160), input channel 3 is to be scanned by the program. System Manual C79000-G8576-C199-07 Step Action 1 Affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. ADB 5 and ADB 7 are marked on the label. 2 Press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. Set the other rockers to the opposite setting. This way sets the start address of the module. ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160 3 Enter the address 160 + 3 x 2 = 166 in the program for input channel 3. 9-41 Analog Input/Output Modules 9.4.5 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install an analog input/output module as follows: 9-42 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90o at the lower end of the module. It must no longer be possible to pull the module forwards. 4 Engage the front connector on the support pin of the module. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (for example, front connectors with 115/230 V AC wiring cannot be plugged into analog modules). 5 Tighten the screw in the upper part of the front connector. System Manual C79000-G8576-C199-07 Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. If the enable input is active, power is removed from the outputs and the module is isolated from the S5 bus. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module by rotating the locking pin by 90 at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards. 6 1 Module Front Connector 5 4 3 Figure 9-15 1 2 3 4 5 6 Support Mount Support Pin 2 Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0110 and 0160 to carry out the wiring of supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules.

System Manual C79000-G8576-C199-07 9-43 Analog Input/Output Modules 9.4.6 Marking of Modules and Front Connectors For the marking of modules and front connectors, labels are supplied with the module and central controller; they are affixed as shown in Figure 9-16. 1 Figure 9-16 1 2 3 4 5 9-44 2 4 1 5 3 Marking and Labeling of Modules Label with the module address under which the module is referenced by the STEP 5 program Labeling strip with the product designation for the module; space to mark the module version and label the channels Label with module address and marking of the required settings for the addressing switch Labeling strip for terminal designations or connection diagrams (strip in the cover of the front connector) Name plate System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.4.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see ordering information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length to DIN 46228.

Caution Only extra-low voltage 60 V DC with safety separation from system voltage may be used for the 24 V DC supply and for the 24 V DC input signals. Safety separation can be implemented to the requirements of, amongst other sources, VDE 0100 Part 410/HD 384-4-41/IEC 60364-4-41 (as functional extra-low voltage with safety separation) or VDE 0805/EN 60950/IEC 6050 (as safety extra-low voltage SELV) or VDE 0106 Part 101. 9-45 Analog Input/Output Modules 9.4.8 Measured-Value Representation Measured-Value Representation as Value and Sign Units (rated input ranges 0 to 1 V, 0 to 10 V, 0 to 20 mA, 4 to 20 mA) Rated Range Byte 0 Byte 1 0...10 V 0...1 V mV 0... 20 mA 4...20 mA 1) 4...20 mA 2) 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 211 210 29 28 27 26 25 24 23 22 21 20 0 0 0 OV 2047 1536 19.99 15.00 1999 1500 39.98 30.00 35.98 28.00 31.98 24.00 0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 3) 1535 1280 1025 14.99 1499 29.98 27.98 1001 20.02 20.02 0 0 0 1 1 1 0 1 1 1 1 1 1 1 1 1 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 4) 10.01 23.98 20.00 16.02 1024 1023 512 511 256 1 0 -1 - 51 10.00 9.99 5.00 4.99 2.5 0.0098 0 -0.009 8 -0.5 1000 999.02 500.00 499.00 250 0.976 0 0.976 -50 20.00 19.98 10.00 9.98 5.0 0.02 0 -0.02 -1 20.00 19.98 12.00 11.98 8.0 4.0156 4 3.9844 3.184 16.00 15.98 8.00 7.98 4.00 0.0156 0 -0.015 6 -0.816 0 0 0 0 0 0 0 1 1 1 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 1 1 5) 1) 2) 3) 4) 5) 0 1 0 1 1 0 0 1 1 0 1 0 1 0 0 0 1 1 0 1 0 1 0 0 0 1 1 0 1 0 1 0 0 0 1 0 0 1 0 1 0 0 0 1 0 0 1 0 1 0 0 0 1 1 0 1 0 1 0 0 0 1 1 0 1 0 1 0 0 0 1 0 0 1 0 1 0 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 With data format setting 0 to 1023 (switch on module) With data format setting 256 to 1279 (switch on module) Overflow Overrange Rated range OV = Overflow bit Shunt Resistor A 50 ohm shunt resistor is used for the 0 to 20 mA range; for 4 to 20 mA, the resistor value is 62.5 ohm. The shunt resistors are permanently fitted to the 463 analog input module. Broken wire detection is not possible. For the 4 to 20 mA current measuring range, a broken wire can be detected with currents > 3 mA. Current Limiting If the positive and negative terminals of the transducer are short-circuited when two-wire transducers are used (4 to 20 mA), the current is limited to approximately 28 mA. Until the thermal current limiting circuit responds (about 3 s) a short-circuit current of about 250 mA flows. Load Voltage The failure of the load voltage can be detected from the result of encoding (values < -51 units). The module 463-4UA13 does not require 24V voltage. A 24V supply is required when connecting a 2-wire measuring transducer. 9-46 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.4.9 Technical Specifications 6ES5 463-4UA12/6ES5 463-4UB12 and 6ES5 463-4UA13 Analog Input Modules Rated input ranges (selectable at front connector) - 0.05 to + 1 V - 0.5 to + 10 V -1 to + 20 mA + 4 to 20 mA for 2-wire transducer + 4 to 20 mA for 4-wire transducer Number of inputs 4 voltage/current inputs Measured value representation 11 bits (two's complement) 1024 units in rated range Overrange 50 % (with full accuracy) Error signal for overflow Yes (upward of 50 % overrange) Measuring principle Integrating Conversion principle Voltage-frequency conversion Isolation Yes, 4 inputs with respect to 0 V and each other Permissible potential difference between ref. potentials of 25 V AC/60 V DC max. sensors and module (UCM) and between sensors (channels) Power Supply - digital section from system bus - analog section from load voltage - enabling of module F+/F- 5 V 5 %; 150 mA typ.

When they are laid separately from power system cables, distances of up to 500 m are possible. An arbitrary mixture of voltage sensor, current sensor, two-wire and four-wire transducers can be connected. For two-wire transducers, there are four short-circuit protected supply terminals at the front connector. ! Caution To use two-wire transducers, the reference potential (common input) of these channels must be connected to L-. This defeats the isolation between the channels and the supply voltage L+/L-. Note that the bus interface of the module is activated with 24 V via enable lines F+ and F- at the front connector. 9-48 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Front Connector Assignments F+ FL+ * * F+ FL+ F+ FL+ * + + 5 + 6 6 + * 4 MU + 5 6 - 7 8 - 6 - 7 - 7 - 7 7 + + + - 14 15 + - 16 16 L- - 15 + L- + + + 26 27 13 - 15 16 L- L- 9 10 11 12 13 MU 16 - L- 25 MU + 27 + - 27 - 28 - 28 - 28 28 1 2 3 4 - 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 + + + 36 - 37 35 + 36 - 37 MU - - 37 33 34 34 + 35 36 - 37 38 36 37 39 40 41 42 Block Diagram of the Module Pin t L+ + +10V +1V Common Common 0-10V 0-20mA 4-20mA Ch 0 + +10V +1V Common Common 0-10V 0-20mA 4-20mA L- Ch 1 Ch.0 Ch.1 Ch.2 Ch.3 + 4x -+ 15V +10V +1V Common Common 0-10V 0-20mA 4-20mA Ch 3 Bus Control F+ FL+ Front Strip Data Memory F+ FL+ Range Range 4-20mA 4-20mA (2-wiretransd.)

You can use the enable inputs to switch off individual modules whilst the PLC is in operation. This means that: The module can no longer be addressed by the user program. Modules which are switched off can be removed or inserted during operation. If this is not necessary, operate the module with the enable input switched off. 9-50 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC. Switching Off the Enable Input The 465 module additionally offers the facility for changing the enable mode. The module has a jumper accessible from above in the vicinity of the addressing switch. Enable Jumper Figure 9-19 Enable Input and Enable Jumper Jumper inserted: Enable input (F+/F-) active (factory setting) Jumper open: Enable input (F+/F-) switched off Examples of functioning of the enable inputs: To switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. The load voltage of individual modules can be monitored without additional circuitry. Any reactions to failure of the load voltage can be programmed in the QVZ (timeout) organization block. System Manual C79000-G8576-C199-07 9-51 Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present. Switching off the CC You should observe the following instructions for switching off CCs and equipment for supplying power to the enable inputs. Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the load power supply is used without an additional capacitor and common shutdown. 230 V AC supply for CC/EU and load power supply b) a) Battery I/O Modules -951 c) F+ CC/EU L+ Power Supply L+ 230 V AC Load Power Supply 24V Supply for the enable inputs from: a) 6ES5 951-4LB11 load power supply b) Battery c) Terminals for 24 V on the front plate of the power supply 9-52 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) I/O Modules Battery b) F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 F per 10 A of load current. Other units which do not meet this condition can be adapted to this requirement by connecting a 10000 F / 40 V capacitor in parallel.

You can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors). Broken Wire Signal To monitor the sensors connected to the inputs, you can use the 6ES5 498-1AA11 range card (through-connection card) to implement the "broken wire detection" mode. You can activate broken wire detection for 8 or 16 inputs in 16-channel operation, and for 4 or 8 inputs in 8-channel operation. Each time the input value is about to be encoded, a constant current is briefly (1.6 ms) switched to the input terminals and the resultant current is checked for a limit value. If a digital voltmeter is used to measure the signal at the input, these current pulses may appear to indicate fluctuation of the signal. The encoded value, however, is not affected. Switching the Tripping Current to the Inactive State If these apparent fluctuations of the signal are disturbing, for example, during startup, you can switch the tripping current to the inactive state on the 465 analog input modules: apply + 24 V to pin 24 of the front connector, and 0 V to L-. You must additionally set the mode switch to "without broken wire detection." In the event of open-circuit of the sensor or its line, the voltage exceeds the limit and a broken wire is indicated (bit 1 in data byte 1). The analog-to-digital converter encodes the value 0. A broken wire signal is only useful when the 6ES5 498-1AA11 through-connection card is used. With all other measurement cards, a broken wire signal will result in incorrect reactions. Further details relating to the broken wire signal can be found in Section 9.5.10. Measuring Range Exceeded If the measuring range is exceeded, the overflow bit (bit 20 of the low byte) is set. Cyclic Sampling/ Selective Sampling You have a choice of the cyclic sampling and selective sampling modes. 9-54 In the cyclic sampling mode, the module continuously encodes all measured values. The digitized measured values are stored under the channel-related address on the module (the high byte under this address, and the low byte under the next higher address). The measured values can then be read by the module at any time without waiting. When you operate the module in this mode, you can set a module address from 0 to 255. System Manual C79000-G8576-C199-07 Analog Input/Output Modules In the selective sampling mode, a measured value is encoded on the central initiative of the CPU. At the start of conversion, the module must be addressed once with a write operation (T PW) by the user program. An active bit (T = 1) is set during encoding. With the transition to T = 0, the measured value becomes valid. With non-constant cycle times, there may be non-periodic measured value aquisition. If you operate the module in this mode, you must set a module address from 128 to 255. You can also use the address range from 0 to 127 for selective sampling after appropriate programming in DB 1 of the user program. Time-Controlled Program Processing Another method is that of time-controlled program processing. With this method, certain program segments (e.g. FB 13) are automatically inserted into program processing at the 100 ms rate by a time-controlled block (OB 13). A constant timebase is thus achieved.

BASP (Output Inhibit) The BASP signal is not interpreted by the 460 analog input module. System Manual C79000-G8576-C199-07 9-55 Analog Input/Output Modules 9.5.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting ( ). One data word = two data bytes is required to process an input. A module with 8 inputs therefore reserves 16 byte addresses, and a module with 16 inputs or outputs reserves 32 byte addresses. Labeling Field You can affix the adhesive label with the desired module address on a free labeling field under the addressing switch. The switch rockers to be set for the module address specified as a decimal number (address bit ADB) are marked by dots on the label. Note Press the individual rockers of the addressing switch downwards with a ballpoint pen or similar object, but not a pencil. Ensure that all the switches are operated properly (meaning pressed past the latching point).

Start Address, Subaddress 9-56 For analog input and analog output modules (8 or 16 inputs) only the lowest address (start address) is set. Other addresses (subaddresses) are decoded on the module. System Manual C79000-G8576-C199-07 Analog Input/Output Modules Note The start address of the analog module must be a multiple of the double channel number. 8 channels : 0, 16, 32, 48, ... 240 16 channels : 0, 32, 64, 96, ... 224 If one of the inputs or outputs (channel 0 to 7 or 0 to 15) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the input or output, based on the start address of the module, is given by: Start address + 2 x channel no. = subaddress Example: Analog input module with 8 or 16 inputs The address is the sum of the significances set with the individual coding switches. 160 = 128 + 32 = 27 + 25 On Setting (Switch Pressed) ADB1 ADB0 8 16 4 2 1 ADB3 ADB2 64 32 ADB7 ADB6 ADB5 ADB4 128 IB 160 A module with 8 or 16 inputs (channel 0 to 7 or 0 to 15) and start address 160 reserves the address range from 160 to address 160 + 7 x 2 = 174 160 to address 160 + 15 x 2 = 190 In this example, the next free address for another module is 176 or 192. With the 465 analog input module, the size of the address range depends on the number of channels set (8 or 16). Addresses already assigned must not be set again. System Manual C79000-G8576-C199-07 9-57 Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. For selective sampling, you can also use the address range from 0 to 127 after appropriate programming in DB 1 of the user program. Example: On an analog input module with start address 160 (IB 160 = input byte 160), input channel 3 is to be scanned by the program. 9-58 Step Action 1 Affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. ADB 5 and ADB 7 are marked on the label. 2 Press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. Set the other rockers to the opposite setting. This way the start address of the module is set. ADB 5 and ADB 7 results in 25 + 27 = 32 + 128 = 160 3 Enter the address 160 + 3 x 2 = 166 in the program for input channel 3. System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.5.5 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install an analog input/output module as follows: System Manual C79000-G8576-C199-07 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90o at the lower end of the module. It must no longer be possible to pull the module forwards. 4 Engage the front connector on the support pin of the module. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (for example, front connectors with 115/230 V AC wiring cannot be plugged into analog modules). 5 Tighten the screw in the upper part of the front connector. 9-59 Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. If the enable input is active, power is removed from the outputs and the module is isolated from the S5 bus. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module by rotating the locking pin by 90o at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards. 6 Module 1 Front Connector Support Mount 5 Support Pin 4 2 3 Figure 9-21 1 2 3 4 5 6 Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0110 and 0160 to carry out the wiring of supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules.

Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see Ordering Information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length to DIN 46228. The maximum terminal area is 2 x 2.5 mm2. Terminal T Type Connector T Type 6ES 497- Cross-Section Max. N off No. Signal or Supply Aux.

System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.5.8 Connecting a Compensating Box for Thermal E.M.F. Measurement If the room temperature fluctuations at the reference point (for example, in the terminal box) affect the measurement result and you do not wish to use a thermostat, you can compensate for the effect of temperature on the reference point with a compensating box. Between - 10 and + 70 oC, it compensates for the change in thermal e.m.f. caused by temperature deviation (compensating box, see Catalog MP 19). Ensure that the compensating box has thermal contact with the terminals. If the compensating box is aligned at 20 oC, this must be taken into account in temperature evaluation (20 oC measuring point temperature = 0 mV). Pins 22 and 23 are extended on analog input modules as an input for the compensating voltage. You must select a common input loop for all inputs on mode switch 2. The compensating box must be connected in a floating circuit. The power supply unit of the compensating box must have a grounded shield winding to avoid AC system interference being picked up. A separate compensating box with its special power supply unit is required for each analog input module.

The voltage at the Pt 100 is picked off at measurement inputs M+ and M-. If only inputs 0 to 3 are assigned to resistance thermometers, you can connect other current and voltage sensors to inputs 4 to 7 by means of a coding key. If you use the Pt 100 for measurement, you cannot utilize channels 12 to 15. Channels 8 to 11 supply the resistance thermometers which are connected at inputs 0 to 3. Note that the mode of the module is set to the 500 mV voltage range. 9-64 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 465 Analog Input Module - Card 1 Pt100 M+ + CH0 MA 2) Range Card for 4 Inputs 6ES5-498-1AA11 2) 0...500mV # CH3 1) Card 2 U/I D MUX 6ES5498CH4 -1AA11 U CM -1AA21 2) -1AA31 U CM -1AA41 2) -1AA51 -1AA61 2) -1AA71 CH7 1) I const.

System Manual C79000-G8576-C199-07 9-65 Analog Input/Output Modules 9.5.10 Broken Wire Signal for Resistance Thermometers An open-circuit in the lines to a resistance thermometer is indicated as follows: Broken Wire at M+ MPt 100 IC+ IC- Module Reaction, Encoded Value 0 0 0 0 0 Error Bit E 1 1 1 1 1 If the mode "without broken wire signal" is selected on the module, an open-circuit of the resistance thermometer is indicated with an overflow. Unassigned channels can be used for voltage or current measurement if the current flow outputs relating to the particular measuring channel are shorted with a wire jumper. Without this jumper, the error bit would be set for this channel and the value 0 would be encoded. Broken Wire Monitoring When set to "resistance thermometer," switch 7 of mode switch I of the 465 analog input module allows broken wire monitoring of the IC+ lines to the resistance thermometer (Pt 100 constant current supply). In the event of open-circuit of this line, the error bit is set as for the other lines. At the "voltage/current" (mV/mA) setting, the IC+ lines are not monitored for broken wire. (The error bit is not set for an open-circuit of this line.) You should choose this switch setting if you exclusively measure voltages or currents. 9-66 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.5.11 Connecting Transducers Two-wire transducer (short-circuit protected supply voltage via the range card of the analog input module) L+ L- Analog Input Module M+ A 4...20 mA + MUX Range Card for 4 Inputs 6ES5-498-1AA51 - M- # D 0 V Bus Four-wire transducer (with separate supply voltage) Analog Input Module M+ 230 V AC A +4...20 mA + MUX Range Card for 4 Inputs 6ES5-498-1AA71 - M- # D Do not exceed max. permissible potential difference! 0 V Bus Four-wire transducer with a two-wire transducer card M+ L+ L- Analog Input Module 230 V AC + A 0...20 mA MUX M- Range Card for 4 Inputs 6ES5-498-1AA71 # D L- (0 Vext) System Manual C79000-G8576-C199-07 0 V Bus 9-67 Analog Input/Output Modules 9.5.12 Measured-Value Representation Digital Measured-Value Representation as Two's Complement Units Input V lt Voltage in mV (rated input range 50 mV) Byte 0 Byte 1 7 6 5 4 3 2 1 0 7 6 5 4 3 2 212 211 210 29 28 27 26 25 24 23 22 21 20 A 1 E 0 OV 4096 100.0 0 1 1 1 1 1 1 1 1 1 1 1 1 0/1 0/1 1 Overflow 4095 2049 99.976 50.024 0 0 1 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0/1 0/1 0 0/1 0/1 0 Overrange 2048 2047 50.0 49.976 0 0 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0/1 0/1 0 0/1 0/1 0 1024 1023 25.0 23.976 0 0 0 0 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0/1 0/1 0 0/1 0/1 0 1 0 -1 0.024 0.0 -0.024 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 1 0 1 0/1 0/1 0 0/1 0/1 0 0/1 0/1 0 -1023 -1024 - 24.976 - 25.0 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0/1 0/1 0 0/1 0/1 0 -2047 -2048 - 49.976 - 50.0 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0/1 0/1 0 0/1 0/1 0 -2049 -4095 - 50.024 - 99.976 1 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0/1 0/1 0 0/1 0/1 0 Overrange -4096 -100.0 1 0 0 0 0 0 0 0 0 0 0 0 1 0/1 0/1 1 Overflow Rated range A = Active bit E = Error bit OV = Overflow bit 9-68 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Digital Measured-Value Representation as Value and Sign Units Input V lt Voltage in mV (rated input range 50 mV) Byte 0 Byte 1 7 S 6 5 4 3 2 1 0 7 6 5 4 3 2 211 210 29 28 27 26 25 24 23 22 21 20 A 1 E 0 OV 4096 100.0 0 1 1 1 1 1 1 1 1 1 1 1 1 0/1 0/1 1 Overflow 4095 2049 99.976 50.024 0 0 1 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0/1 0/1 0 0/1 0/1 0 Overrange 2048 2047 50.0 49.976 0 0 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0/1 0/1 0 0/1 0/1 0 1024 1023 25.0 23.976 0 0 0 0 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0/1 0/1 0 0/1 0/1 0 1 0 -0 -1 0.024 0.0 0.0 -0.024 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 0/1 0/1 0/1 0/1 -1023 -1024 - 24.976 - 25.0 1 1 0 0 0 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 0/1 0/1 0 0/1 0/1 0 -2047 -2048 - 49.976 - 50.0 1 1 0 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 0/1 0/1 0 0/1 0/1 0 -2049 -4095 - 50.024 - 99.976 1 1 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 1 0/1 0/1 0 0/1 0/1 0 Overrange -4096 -100.0 1 1 1 1 1 1 1 1 1 1 1 1 1 0/1 0/1 1 Overflow 0/1 0/1 0/1 0/1 0 0 0 0 Rated range A = Active bit E = Error bit OV = Overflow bit Bit 212 is interpreted as the sign.

If you require a representation from 0 to 2048, you must subtract 512 units by software. Please note the following: a broken wire signal cannot be emitted. detection of the overrange can be achieved by scanning bits 29 and 211. a broken wire can be detected with currents < 3 mA. Current Limiting If you short-circuit the positive and negative terminals of the transducer when using the 6ES5 498-1AA51 range card (for a two-wire transducer), the current is limited to about 28 mA. Until the thermal current limiting circuit responds in the range card (about 3 s), a short-circuit current of approximately 250 mA flows.

System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.6 The 466 Analog Input Module 9.6.1 Design The module is designed as a plug-in PCB for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals. 9.6.2 Special Features of the 466 Analog Input Module The 466 analog input module processes the digital input signals by encoding the instantaneous value; periodic system interference is therefore not suppressed. Measuring Range 9.6.3 You select the measuring ranges with a switch setting for every four channels. Startup for Analog Input 466-3LA11 Introduction The mode of the 466 analog input module must be set exclusively via switches on the board. Figure 9-26 shows the designations and locations of switches on the board.

The following 42-pin K-type front connectors are required: 6ES5 497-4UA12 for crimp connection 6ES5 497-4UB31 for srew connection Ensure that all the switches are operated properly (meaning pressed past the latching point). 9-84 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Setting the type of measurement Measurement with respect to ground/differential measurement The type of measurement (with respect to ground or differential measurement) is set with switch S9. The switch settings relate to the locations on the module shown in Figure 9-28: Type of Measurement Switch position S9 1 8 Measurement with regard to ground ON OFF 1 8 Differential measurement Current/Voltage Measurement for Individual Channel Groups ON OFF If you have preset differential measurement on switch S9, two channel groups of four channels each are available. You can configure each channel group separately for current or voltage measurement. You set this with switches S5, S6, S7 and S8. Switches S5 and S7 allow three settings (left, midpoint and right); switches S6 and S8 allow two settings (left and right).

For each channel group (i.e. for every four inputs), you can select a range which is independent of the other channel groups. You set the ranges with switches S1 and S2. The assignment of the switches to the channel group is shown in Figure 9-28. 1 2 3 4 S1 5 6 7 8 1 2 3 4 S2 5 6 7 8 ON OFF Channel Group I (Channel 0...3) Channel group II (Channel 4...7) Channel group III (Channel 8...11) Channel group IV (Channel 12...15) Figure 9-29Assignment of the Switches S1 / S2 and the channel group The same measuring range coding is valid for each channel group. Given in the following table, therefore, is the setting of the measuring range for only one channel group. The switch settings relate to the locations on the module shown in the figure. Note that you must additionally set the type of measurement (current/voltage) with switches S5 to S8!

Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install an analog input/output module as follows: System Manual C79000-G8576-C199-07 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90o at the lower end of the module. It must no longer be possible to pull the module forwards. 4 Engage the front connector on the support pin of the module. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (e.g. front connectors with 115/230 V AC wiring cannot be plugged into analog modules). 5 Tighten the screw in the upper part of the front connector. 9-91 Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. If the enable input is active, power is removed from the outputs and the module is isolated from the S5 bus. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module by rotating the locking pin by 90o at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards. 6 Module 1 Front Connector Support Mount 5 Support Pin 4 3 Figure 9-30 1 2 3 4 5 6 2 Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0110 and 0160 to carry out the wiring of supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules. Detailed information on cabinet assembly, cabinet ventilation and protective measures can be found in Chapter 3. 9-92 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.6.6 Marking of Modules and Front Connectors For the marking of modules and front connectors, labels are supplied with the module and central controller; they are affixed as shown in Figure 9-31. 1 Figure 9-31 1 2 3 4 5 System Manual C79000-G8576-C199-07 2 4 1 5 3 Marking and Labeling of Modules Label with the module address under which the module is referenced by the STEP 5 program Labeling strip with the product designation for the module; space to mark the module version and label the channels Label with module address and marking of the required settings for the addressing switch Labeling strip for terminal designations or connection diagrams (strip in the cover of the front connector) Name plate 9-93 Analog Input/Output Modules 9.6.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see ordering information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length to DIN 46228. The maximum terminal area is 2 x 2.5 mm2. ! 9-94 Caution Only extra-low voltage 60 V DC with safety separation from system voltage may be used for the 24 V DC supply and for the 24 V DC input signals. Safety separation can be implemented to the requirements of, amongst other sources, VDE 0100 Part 410/HD 384-4-41/IEC 60364-4-41 (as functional extra-low voltage with safety separation) or VDE 0805/EN 60950/IEC 60950 (as safety extra-low voltage SELV) or VDE 0106 Part 101. System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.6.8 Connecting Sensors to the 466 Analog Input Module The connections for the 466 analog input module depend on the type of measurement (with respect to ground or differential measurement). Measurement with Respect to Ground For measurement with respect to ground, all signal lines have a common reference point. This is achieved by connecting all the M inputs in use to one point. Since this type of measurement is susceptible to interference, the signal sources should be arranged in the vicinity of the 466 analog input module. 16 channels are available; unused channels must be shorted (jumper between M+ and M-). The channels have the following designations on the module: Channel 0: Channel 1: : Channel 15 M0 + M0 M1 + M1 : M15 + M15 - Channels are arranged in groups of four, for which you can set separate measuring ranges: Channel group I: Channel group II: Channel group III: Channel group IV: System Manual C79000-G8576-C199-07 Channels 0 to 3 Channels 4 to 7 Channels 8 to 11 Channels 12 to 15 9-95 Analog Input/Output Modules The following figure shows the connection of sensors to the module. For measurement with respect to ground, all the M- connection points are interconnected internally on the module. Analog Input Module M+ U E2 + M+ U E1 MUX + M- - U ISO 0 V Bus U E1/2: Input Voltage U ISO: Potential Difference : Equipotential; this potential is established by the sensor reference potential (external reference potential) Figure 9-32 Connecting Sensors to the 466 Analog Input Module (Measurement with Respect to Ground) Differential Measurement The differential measurement is a method of compensating for interference on the line. Each signal source is assigned its own signal reference line. The differential measurement between signal line and signal reference line thus compensates for the interference acting on both lines. You must also short-circuit the unused channels with this measuring method (jumper between M+ and M-). Differential measurement is required: if the sensors are at different potentials; if various signal sources are not close to each other; if there is a need to measure signals with high precision; and when a high level of interference is expected. 9-96 System Manual C79000-G8576-C199-07 Analog Input/Output Modules The channels have the following designations on the module: Channel 0: Channel 1: : Channel 7: M0 + M0 M1 + M1 : M7 + M7 - Channels are arranged in groups of four, for which you can set separate measuring ranges: Channel group I: Channel group II: Channels 0 to 3 Channels 4 to 7 The following figure shows the connection of sensors to the module. You must observe the following condition: UE + UCM < 12 V (i.e. the sum of the set voltage range and common-mode voltage must be less than 12 V; current measuring ranges correspond to a voltage of 2.5 V).

The following table describes their significance in more detail. Bit OV * Significance Signal Status Meaning of the Signal Status Overflow bit 1 Range exceeded * E Error bit 1 Broken wire A Active bit 0 Not used A measuring-point overflow does not affect the overflow bits of the other channels; i.e. the measured values of unaffected channels are correct and can be evaluated. Please note the following special features: Bit 7 in the high byte (212) indicates the sign for bipolar measured-value representation (two's complement and value with sign). Bit 6 in the high byte (211) is not used in the case of bipolar measured-value representation (no overrange). The 466 module has no overrange. Selective sampling is not possible with the 466 module (active bit is not set). 9-98 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Shown in the following tables is the representation of the measured value as a function of the selected measuring range.

System Manual C79000-G8576-C199-07 9-105 Analog Input/Output Modules 9.7 9.7.1 The 470 Analog Output Module Design The module is designed as a plug-in PCB for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals. Addressing Switch, Mode Switches Situated on each module is an addressing switch with six rockers to set the module address. The modules are protected by covers on both sides. Addressing Switch Blade Connector Front Connector Figure 9-37 9.7.2 Analog Output Module Function of the Enable Input The 470 module has an enable circuit. You can use the enable inputs to switch off individual modules whilst the PLC is in operation. This means that: The module can no longer be addressed by the user program. On analog output modules, the last analog value to be output is retained. Modules which are switched off can be removed or inserted during operation. If this is not necessary, operate the module with the enable input switched off. 9-106 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC. Switching Off the Enable Input The -4Ux12/13-type modules additionally offer the facility for changing the enable mode. The modules have a jumper accessible from above in the vicinity of the addressing switch. Enable Jumper Figure 9-38 Enable Input and Enable Jumper Jumper inserted: Enable input (F+/F-) active (factory setting) Jumper open: Enable input (F+/F-) switched off Examples of functioning of the enable inputs: To switch off individual subprocesses, i.e. outputs of various modules can be operated from a common load supply and yet activated separately. The load voltage of individual modules can be monitored without additional circuitry. Any reactions to failure of the load voltage can be programmed in the QVZ (timeout) organization block. System Manual C79000-G8576-C199-07 9-107 Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present. However, you must ensure that the 24 V load supply for analog output modules is switched off together with the PLC. If the supply voltage is still present at the modules and the PLC is switched off, the output values can drift. (The analog holding elements for the outputs will no longer be refreshed with the current value, because there is no 5 V supply to the modules from the bus.) Switching Off the CC You should observe the following instructions for switching off CCs and equipment for supplying power to the enable inputs. Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the load power supply is used without an additional capacitor and common shutdown. 230 V AC supply for CC/EU and load power supply b) a) -951 Battery I/O Modules c) F+ CC/EU L+ Power Supply L+ 230 V AC Load Power Supply 24V Supply for the enable inputs from: a) 6ES5 951-4LB11 load power supply b) Battery c) Terminals for 24 V on the front plate of the power supply 9-108 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) I/O Modules Battery b) F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 F per 10 A of load current. Other units which do not meet this condition can be adapted to this requirement by connecting a 10000 F / 40 V capacitor in parallel.

Once output, a value is retained. Function Block You can output analog values to the process via analog output modules with a function block from the "basic functions" package. 9.7.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting ( ). One data word = two data bytes is required to process an input or an output. A module with 8 inputs or outputs reserves 16 byte addresses. Labeling Field You can affix the adhesive label with the desired module address on a free labeling field under the addressing switch. The switch rockers to be set for the module address specified as a decimal number (address bit ADB) are marked by dots on the label. Press the individual rockers of the addressing switch downwards with a ballpoint pen or similar object, but not a pencil. On Setting (Switch Pressed) Addressing Switch Free Field for Label with Module Address and marked Switch Settngs ADB1 ADB0 8 16 32 4 2 1 ADB3 ADB2 ADB7 ADB6 ADB5 ADB4 128 64 Address (Decimal) Decimal Signification of the Address Bit Address Bit ADB0 and ADB1 are not assigned ADB2 is not connected Figure 9-39 Labeling of the Addressing Switch The address under which the module is referenced by the STEP 5 program is independent of the slot. 9-110 System Manual C79000-G8576-C199-07 Analog Input/Output Modules Start Address, Subaddress For analog output modules ( 8 outputs) only the lowest address (start address) is set. Other addresses (subaddresses) are decoded on the module. Note The start address of an analog module must be a multiple of the double channel number. 8 channels : 0, 16, 32, 48, ... 240 Ensure that all the switches are operated properly (meaning pressed past the latching point). Do not use a pencil to set the addressing switch. If one of the outputs (Channel 0 to 7) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the output, based on the start address of the module, is given by: Start address + 2 x channel no. = subaddress Example: Analog output module with 8 outputs The address is the sum of the significances set with the individual coding switches. 160 = 128 + 32 = 27 + 25 On Setting (Switch Pressed) ADB1 ADB0 8 16 4 2 1 ADB3 ADB2 64 32 ADB7 ADB6 ADB5 ADB4 128 IB 160 A module with 8 outputs (Channel 0 to 7) and start address 160 reserves the address range from 160 to address 160 + 7 x 2 = 174 In this example, the next free address for another module is 176. Addresses already assigned must not be set again. System Manual C79000-G8576-C199-07 9-111 Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255. For selective sampling, you can also use the address range from 0 to 127 after appropriate programming in DB 1 of the user program. Example: On an analog output module with 8 outputs with start address 144 (IB 144 = output byte 144), output channel 7 is to be scanned by the program. 9-112 Step Action 1 Affix the self-adhesive label with address 160 on the free field under the addressing switch on the module. ADB 4 and ADB 7 are marked on the label. 2 Press the appropriate rockers of the addressing switch down on the side marked by a dot on the module cover. Set the other rockers to the opposite setting. This sets the start address of the module. ADB 4 and ADB 7 results in 24 + 27 = 16 + 128 = 144 3 Enter the address 144 + 7 x 2 = 158 in the program for input channel 7.

Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched. During operation, the front connector and module must not be removed or inserted without the enable jumper or active enable circuit. Install an analog output module as follows: System Manual C79000-G8576-C199-07 Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Insert the module at the desired slot in the subrack and push it back in the guides. 3 Latch the module by rotating the locking pin by 90o at the lower end of the module. It must no longer be possible to pull the module forwards. 4 Engage the front connector on the support pin of the module. The width of the support pin also provides keying to prevent front connectors from being fitted to the wrong modules (for example, front connectors with 115/230 V AC wiring cannot be plugged into analog modules). 5 Tighten the screw in the upper part of the front connector. 9-113 Analog Input/Output Modules Remove an analog output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first. If the enable input is active, power is removed from the outputs and the module is isolated from the S5 bus. 3 Swing the front connector out and lift it away from the support pin of the module. 4 Release the module by rotating the locking pin by 90o at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards. 6 Module 1 Front Connector Support Mount 5 Support Pin 4 3 Figure 9-40 1 2 3 4 5 6 2 Module with Front Connector Screw Locking pin Support mount Support pin Grip Backplane connector Comply with VDE Specifications 0110 and 0160 to carry out the wiring of supply and signal lines which are to be connected to the programmable controllers and front connectors of the modules.

Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. When the crimp contact is inserted in the plastic body of the front connector, a click can clearly be heard. This indicates that the contact is engaged. For jumpering or to correct the wiring, you can remove the contacts with a releasing tool (see ordering information) without having to pull out the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection. You can use ferrules of 7 mm in length to DIN 46228. The maximum terminal area is 2 x 2.5 mm2. Terminal T Type Connector T Type 6ES 497- Cross-Section Max. N off No. Signal or Supply Aux.

System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.7.8 Connecting Loads to the 470 Analog Output Module The voltage at the load is measured at a high resistance via the sensor lines (S+/S-) of voltage output QV, so that voltage drops on the load lines do not falsify the load voltages. Lines S+(x) and S-(x) should therefore be directly connected to the load (four-wire circuit). The voltage drops on the lines from QV(x) to the load and from the load to MANA must not exceed 3 V.

When voltage outputs are not used, the S+(x) sensor lines in the front connector must be connected to the corresponding voltage output terminals (QV(x)) with wire jumpers. The S-(x) sensor lines must be connected to MANA with wire jumpers. You must also insert the same jumpers if only current outputs are used. Unused current outputs may remain open. The maximum load for the current outputs including line resistance, must not exceed 300 ohms. Connecting Loads to Voltage Outputs The voltage outputs of the 470 analog output module are wired as follows: QV0 QV1 QV2 QV3 S+0 S+1 S+2 S+3 Jumper + + + - - S-0 S-1 S-2 S-3 Jumper M ANA M ANA No Load at QV3 Figure 9-44 Connecting Loads Four-Wire Circuit The S+(x) and S-(x) sensor lines must be routed to the load (four-wire circuit) if the voltage drop on the lines to the load is not negligible. The common connection for the voltage outputs is MANA. If the voltage drop on lines to the load is negligible, you can connect S+(x) to QV(x) and S-(x) to MANA in the front connector. When voltage outputs are unused, you must insert jumpers in the front connector, e.g. QV(3) to S+(3) and S-(3) to MANA for unused voltage output 3 (see previous section). 9-118 System Manual C79000-G8576-C199-07 Analog Input/Output Modules 9.7.9 Measured-Value Representation Digital Measured-Value Representation as Two's Complement Units Output Voltage or Current of the 470 Analog Output Module -4UA/B12/13 -4UA12/13 1280 12.5 V 1025 10.0098 V 1024 1023 512 256 128 64 1 0 -1 - 64 - 128 - 256 - 512 -1024 -1025 -1280 -4UC12/13 Byte 0 Byte 1 7 6 5 4 3 2 1 0 7 6 5 4 3 211 210 29 28 27 26 25 24 23 22 21 20 x 2 x 1 x 0 x 25.0 mA 6.0 V 24.0 mA 0 1 0 1 0 0 0 0 0 0 0 0 Overrange 20.0195mA 5.004 V 20.016 mA 0 1 0 0 0 0 0 0 0 0 0 1 10.0 V 9.99 V 5.0 V 2.5 V 1.25 V 0.625 V 9.8 mV 0V - 9.8 mV - 0.625 V - 1.25 V - 2.5 V - 5.0 V - 10.0 V 20.0 mA 19.98 mA 10.0 mA 5.0 mA 2.5 mA 1.25 mA 19.5 mA 0 mA 0 mA 0 mA 0 mA 0 mA 0 mA 0 mA -10.0098V -12.5 V 0 mA 0 mA System Manual C79000-G8576-C199-07 5.0 V 4.995 V 3.0 V 2.0 V 1.5 V 1.25 V 1.004 V 1.0 V 0.996 V 0.75 V 0.5 V 0V -1V - 3.0 V 20.0 mA 19.98 mA 12.0 mA 8.0 mA 6.0 mA 5.0 mA 4.016 mA 4.0 mA 3.984 mA 3.0 mA 2.0 mA 0 mA 0 mA 0 mA - 3.004V 0 mA - 5.0 V 0 mA 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 0 0 0 0 0 1 1 1 1 1 1 0 1 1 0 0 0 0 0 1 1 1 1 1 0 0 1 0 1 0 0 0 0 1 1 1 1 0 0 0 1 0 0 1 0 0 0 1 1 1 0 0 0 0 1 0 0 0 1 0 0 1 1 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 1 Rated Range 0 1 0 0 0 0 0 1 0 1 1 1 1 1 1 1 1 1 1 Overrange 1 0 1 1 0 0 0 0 0 0 0 0 9-119 Analog Input/Output Modules 9.7.10 Technical Specifications 6ES5 470-4UA12, 6ES5 470-4UB12 and 6ES5 470-4UC12 Analog Output Modules Rated output ranges - 6ES5 470-4UA12 (-4UA13) - 6ES5 470-4UB12 (-4UB13) - 6ES5 470-4UC12 (-4UC13) 0 to 10 V and 0 to 20 mA parallel for 1024 units 10 V for 1024 units 1 to 5 V and 4 to 20 mA parallel for 0 to 1024 units Number of outputs 8 voltage and current outputs each, no-load and short-circuit-proof Isolation Yes 8 outputs with respect to Mext , M and L+/L- Measured value representation 12-bit (two's complement) Linearity in the range of 1024 units 2 LSB = 0.2 % Operational error limits (0 to 60 oC) 0.6 % Temperature coefficient for voltage and current outputs 1 x 10-4/K Permissible overrange Approx. 25 % ( 1024 to 1272 units) Fault current at voltage output Approx. 25 mA No-load voltage at current output Approx. 18 V Load impedance - at voltage output - at current output 3.3 k 300 Delay between data transfer and analog value output to > 99% 5ms Capacitive load including line capacity for -4UA12 from version 03 and for -4UB12 and -4UC12 from version 04: 100 nF max.

The module monitors the data bus, the address bus and the control signals MEMW/, MEMR/ and RDY/. Faults are displayed via four red LEDs on the front panel. A group signal is output at the same time via a floating contact. Following a fault, the module can be reset by means of the RESET key on the front panel or the RESET input (see Section 10.2.3). 10.1.1 Design The monitoring module is designed as a plug-in PCB in double Euroformat with a 32-pin backplane connector for the S5 bus. A connector for the relay contact and RESET input as well as one green LED, four red LEDs and a RESET key are located on the front panel. 8 7 65 4 3 2 1 Operation (green LED) OFF ON 8 7 654 3 2 1 DB Control signal fault (red LED) Address bus fault (red LED) Data bus fault (red LED) S5 1s ADB OFF ON 500ms 250ms 125ms R/W Command output inhibit (red LED) QVZ PESP BASP S1 8 7 654 3 2 1 OFF ON S2 Bus RUN 876543 21 OFF ON S3 8 7 654 3 2 1 OFF ON X4 S4 128 64 32 16 8 4 2 1 RESET key 1 Relay contact RESET input 6 Figure 10-1 Location of the Coding Switches Note Ensure that all the switches are operated properly (meaning pressed past the latching point). 10-2 System Manual C79000-G8576-C199-07 Monitoring Module 10.1.2 Mode of Operation 10.1.3 Block Diagram Address bus Address comparison Ouput Data Address comparison S1 Bit S5 Bus inversion S2 Read and compare data Preselection of time Time monitoring Address comparison Address comparison S3 Time monitoring S4 Time monitoring 1 DB Data bus MEMR MEMW RDY ADB Control signal monitoring R/W 1 S CPKL R 1 Edge BASP X4/4 RESET input RUN X4/3 X4/5 L+ (24V) X4/6 L- internal +5V internal 0V X4/2 X4/1 Relay contact Figure 10-2 Block Diagram System Manual C79000-G8576-C199-07 10-3 Monitoring Module 10.1.4 Fault Detection From an address which has been set at switch S1, the data (55H or AAH) is read by the CPU from the monitoring module. This data is to be written back by the CPU to the address set at switch S2. The module inverts the accurate incoming data bit by bit (from 55H to AAH or vice versa) which is read again in the next cycle from the address set at S1. Data Bus Faults If the data which has been set on the monitoring module is not returned within the set monitoring time, the module signals a data bus fault. Detectable faults Interruptions of the data lines, short circuits to ground and + 5V, short circuits between adjacent data lines, e.g. DB0-DB1, DB1-DB2 etc. Non-detectable faults Short circuits between even data lines DB0-DB2-DB4-DB6 and between odd data lines DB1-DB3-DB5-DB7. Address Bus Faults The addresses which have been set at switches S3 and S4 are only "listened to" by the monitoring module, i.e. they do not output an acknowledgement signal (RDY/) and are not active on the data bus. If one or both addresses are not accessed again within the monitoring time, the monitoring module signals an address bus fault. Detectable / non-detectable faults The same as for the data bus, if the inverse addresses 85 (55H) and 170 (AAH) have been set at the addressing switches S3 and S4 of all monitoring modules. 10-4 System Manual C79000-G8576-C199-07 Monitoring Module Control Line Faults A control line fault (R/W) occurs if - the write signal (MEMW/) and the read signal (MEMR/) are active simultaneously, - the acknowledgement signal (RDY/) is active without a (MEMW/) or (MEMR/) signal and - the address line 'peripheral memory' (PESP') has not changed from status "1" to "0." Evaluation of the control signal (PESP') can be turned off with the S5/7 switch. If the module is used in a programmable controller into which only I/O modules may be inserted (i.e. no memory modules or CPs), this switch must always be turned off. In this configuration, only I/O accesses to the bus are performed and the PESP` signal always has the status "1." It should also be turned off when using the IM 301, IM 302 1), IM 304 and IM 308 interface modules for expansion units since a permanent PESP` signal can be applied to them. BASP If a command output inhibit (BASP) is active, the "BASP" LED is lit. Messages If one or more faults occur, the corresponding LEDs are lit, the relay contact commutes and the module no longer acknowledges with the RDY/ signal. This timeout can be suppressed by opening the S5/8 switch. 10.1.5 Resetting There are several ways of resetting the module: - CPKL/ signal = "1" (when the PLC is switched on); - Trailing edge of the BASP signal (during startup of the PLC or following return of the load voltage); - Applying 24 V to the front connector X4 between connections 4 (RESET input) and 6 (L-); - Linking connections 4 (RESET input) and 5 (L+) with connector X4. 1) In the S5-115U, the monitoring module cannot be used together with the IM 302 / 311 link.

System Manual C79000-G8576-C199-07 10-7 Monitoring Module 10.3 Operation Switch S1 (Read) and S2 (Write) The addresses set at these switches are acknowledged by the monitoring module with RDY/ and are therefore not to be used again for inputs and outputs in this programmable controller (double addressing is not allowed). Switch S3 (Listen) and S4 (Listen) No acknowledgement signal (RDY/) is returned by the monitoring module to the addresses set the switches S3 and S4. These addresses must be accessed by the programmable controller as input or output addresses. This means that they must be occupied by I/O modules or by one monitoring module at switches S1 and S2. These modules must have been inserted into the last expansion unit. To achieve optimum address bus monitoring, inverse addresses should be used [e.g. 85 (55H) 2) and 170 (AAH)]. It is advisable to make sure that the setting of switches S3 and S4 is the same on all monitoring modules used. The setting of switches S1and S2 as well S3 and S4 should be the same on the monitoring module in the last expansion unit. Switch S1 Input address can be accessed using MEMR/ (READ) * S2 1) 10-8 Output address can be accessed using MEMW/ (WRITE) Acknowledged by module with RDY/ * * S3 * * S4 * * * Select addresses 213 (D5H) and 170 (AAH) when using the module in the S5-115U.

The addresses 85 (55H) or 170 (AAH) of this monitoring module must be coded at switches S1 or S2, respectively. These addresses may no longer be occupied for I/O tasks. 10-10 System Manual C79000-G8576-C199-07 Monitoring Module Example 2 S5-115U S1 e.g. 128 (80H) 6) e.g. 129 (81H) 6) 213 (D5H) 6) S2 e.g. 128 (80H) 6) e.g. 129 (81H) 6) 170 (AAH) 6) S3 213 (D5H) 7) 8) 213 (D5H) 7)8) 213 (D5H) 7)8) S4 170 (AAH) 7) 170 (AAH) 7) 170 (AAH) 7) User program in OB 1 or FB 0 without S5-DOS with S5-DOS L PB 128 L PY 128 T PB 128 T PY 128 L PB 129 L PY 129 T PB 129 T PY 129 L PB 213 8) L PY 213 8) T PB 170 T PY 170 BE BE 6) When using the monitoring module in the S5-115U, always select addresses > 127 since that is the only way to address byte to byte. 7) To achieve maximum fault detection, select inverse addresses > 127, e.g. 213 (D5H) and 170 (AAH). In this combination, the address bit ADB 7 is not monitored. 8) If ADB 7 is also to be monitored, the address 84/85 (54H/55H) in the last expansion unit must be occupied by an input or output module and cyclically accessed by the user program. Set address 85 (55H) in place of 213 (D5H) at switch S3 of all monitoring modules. Select any address between 128 (80H) and 255 (FFH) for switch S1 of the monitoring module in the last expansion unit. As an alternative, you may access the address at S1 of the monitoring module in the last expansion unit via direct access (without process image) using L PB 85 or L PY 85. Then, the addresses 84 and 85 (54H) and (55H) in the process image may no longer be used by other inputs. The address at S3 of all monitoring modules is then also to be set to 85 (55H).

If none of the four switches S5/1 to S5/4 is in the ON position, for safety reasons the monitoring time has been set to 1 s. If serial interface modules and the link between IM 304 and IM 314 are used, the PESP` monitoring is to be switched off (see Section 10.1.4: Control line faults). Should the acknowledgement signal (RDY/) not be suppressed in the event of a fault, the switch S5/8 must be in the OFF position. When a BASP signal is active, the RDY/ signal will always be output.

B-2 B.2 Electrostatic Charging of Persons B-3 B.3 General Protective Measures Against Electrostatic Discharge Damage B-4 B-1 Guidelines for Handling Electrostatically-Sensitive Devices (ESD) B.1 What is ESD? Definition All electronic modules are equipped with large-scale integrated ICs or components. Due to their design, these electronic elements are very sensitive to overvoltages and thus to any electrostatic discharge. These Electrostatically- Sensitive Devices are commonly referred to by the abbreviation ESD. Electrostatically-sensitive devices are labeled with the following symbol: ! B-2 Caution Electrostatically-sensitive devices are subject to voltages that are far below the voltage values that can still be perceived by human beings. These voltages are present if you touch a component or the electrical connections of a module without previously being electrostatically discharged. In most cases, the damage caused by an overvoltage is not immediately noticeable and results in total damage only after a prolonged period of operation. System Manual C79000-G8576-C199-07 Guidelines for Handling Electrostatically-Sensitive Devices (ESD) B.2 Electrostatic Charging of Persons Charging Every person with a non-conductive connection to the electrical potential of its surroundings can be charged electrostatically. Figure B-1 shows you the maximum values for electrostatic voltages which can build up on a person coming into contact with the materials indicated in the figure. These values are in conformity with the specifications of IEC 801-2.

You thus avoid electrostatic charging. Avoid Direct Contact You should touch electrostatically-sensitive devices only if it is unavoidable (for example, during maintenance work). Hold modules without touching the pins of components or printed conductors. In this way, the discharged energy cannot affect the sensitive devices. If you have to carry out measurements on a module, you must discharge your body before you start the measurement by touching grounded metallic parts. Use grounded measuring devices only.
