Glossary - SIMATIC D7-SYS Edition 12.2004 v Glossar A Acknowledge button Button on the front panel of a SIMATIC TDC/SIMADYN D CPU/FM 458-1 DP which is used to acknowledge an error message displayed on the 7segment or LED display. Address book The address book links display variables of the operator control and visualization systems COROS LSB as well as SIMATIC WinCC to the block I/O in the CFC charts for SIMADYN D. When compiling, the charts are generated if the "create address book" field is activated in the dialog box "Options for compilation". The "Options for compilation" dialog box is opened in the CFC by selecting the menu command Options > Settings > Compilation. Address connection Connection AT, AR or US at the function blocks. Address parameters are specified at the address connection. Address parameters Identifies the communication partner at the address connection of a send- or receive block. It consists of a channel name and depending on the coupling type, several address stages. Address stage Part of an address parameter (address stages 1 and 2). Address stages only have to be configured for serial couplings; an address stage does not have to be configured for parallel couplings "rack coupling", "buffer memory coupling" and "CPU-local coupling". Also refer to: Channel name Autorouting Glossary - SIMATIC D7-SYS Edition 12.2004 The autorouter is a program section to automatically generate connecting lines, connectors and margin entries. G-1 Glossary B Background processing If there are no tasks from the user program to be processed in the SIMATIC TDC/SIMADYN D-CPU/FM 458-1 DP, then it goes into the background processing mode to execute the background task. Background task The background task consists of: * the test mode of the operating system in which for example, memory test routines run * and simultaneously a local service at the CPU front panel via the diagnostics interface. Backplane bus SIMADYN D subracks have an L bus and if required, a C bus. They include the power supply- and data lines for the modules. Basic sampling time, basic clock cycle The cycle time of the CPU/FM 458-1 DP time generator is derived from the sampling times of the individual cyclic tasks. Basic clock synchronization The basic sampling times of several CPUs are synchronized. In this case, a CPU acts as master and sends its basic clock cycle along the backplane bus. The synchronized CPUs do not generate their basic clock cycle themselves, but take it from the backplane bus. Also refer to: Interrupt synchronization BICO technique Using BICO technique, interconnections between I/Os of blocks can be changed using Masterdrive operator control devices. This means that configured software can be modified without CFC. Interconnections on a technology CPU or SIMADYN D CPU module can be changed. Also refer to: Technology connectors Block Blocks are parts of the user program which are clearly defined as a result of their function, structure or application. The CFC operates with preconfigured block types, which are inserted in a chart. When inserting, an instance is generated from a block type. These instances and their graphic representation are blocks in the sense of the CFC. Also refer to: Function block Block body Lower part of the block, which contains the I/Os. Block class The function blocks which can be called-up in the CFC, are sub-divided into block classes, which include the functionality associated with the particular blocks (e.g. closed-loop control blocks). Block header The upper part of the block, which among other things, contains the name and the task assignment (run-time properties). Block I/O, I/O Block input or block output Block input, input Block I/O which can be connected with a block output or global operand having the same data type, or which can also be parameterized with values. Block interface This consists of the I/Os of a block. G-2 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary Block library A block library includes a number of block types. A block library must be imported into the CFC before its function blocks can be used in the CFC. Also refer to: User library, System library, Code library Block output, output Block I/O which can be connected with block inputs and global operands having the same data type. Block type Block types are pre-defined program sections which can be inserted into a block library and into a CFC chart. Instances are generated. As many instances as required can be set-up from a block type. For SIMATIC TDC/SIMADYN D and FM 458-1 DP there are: * Function blocks * Block types generated from charts. Also refer to: Block Boot interface The boot interface is the upper CF7 module connection, which is located to the far left in the subrack. Conditions for using the boot interface: - An SS4- or SS52 sub-module is inserted in the boot interface - The CPUs of the subrack are in the STOP condition after a boot error. Buffer memory module, buffer memory Glossary - SIMATIC D7-SYS Edition 12.2004 Module to transfer data between several CPUs within a subrack. G-3 Glossary C C bus One of the two backplane buses of a SIMADYN D subrack. Not all of the subrack types have a C bus (refer to the subrack catalog in HWConfig). Also refer to: L bus Central block Function block to initialize and monitor couplings. CFC, CFC editor Continuous Function Chart. Configuring tool to define continuous sequences in a user-friendly fashion by graphically interconnecting complex function in the form of blocks. CFC chart, chart Special graphic unit, which is generated using the CFC configuring tool. A CFC chart comprises 1 to 26 chart partitions, each with 6 sheets, which may contain overflow sheets. Change memory The change memory is a memory area in which the configuring changes, made with the CFC in the test mode are saved. It is located in the memory module inserted in the CPU/FM 458-1 DP. Channel Area in a data interface, which is reserved for two or more communication partners. The area can be set-up from the sender or from the receiver. When firmware is the coupling partner, the area is always set-up from a SIMADYN D CPU (and not from the firmware). A channel always consists of a channel manager and one or two net data buffers. Configuring engineers cannot directly access these areas. Channel administration Part of a channel, via which two coupling partners can communicate how the net data buffers are to be interpreted. For instance, this indicates whether new net data have just been entered or were already entered, or if the last net data have already been read etc. Configuring engineers cannot directly access this area. Channel name Part of an address parameter. Channel names must always be specified and allow senders and receivers to find their communication partner. Thus, channel names must be uniquely assigned at each data interface. Also refer to: Address stage Chart container Refer to chart folder. Chart folder Container in the project structure; contains the charts of the user program of a CPU/FM 458-1 DP. Chart interface A CFC chart can include an interface, which allows input- and output parameters to be assigned to a chart. This means that the chart can be used just like a block or can be compiled to create a block type. Chart nesting A max. of 8 CFC charts can be nested. Charts generated in this fashion are called nested charts. Chart partition Part of the CFC chart. A CFC chart is sub-divided into a maximum of 26 chart partitions (designated: A ... Z), each with 6 sheets. Code library A file, which includes the executable code for all block types of a block library. G-4 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary Comment Possible comments at block I/O are: * Pseudo comments * Comments text: Comment texts can be as long as required and comprise any number of characters, but they may not start with @. A comment can include several pseudo comments, separated by blanks, followed by "standard" comments text, e.g. "@TP_H089 @DATX ...". Communications partner Partner, which further processes the net data. This can be a sender/receiver within SIMADYN D or also in another system/device. Also refer to: Channel, Coupling partner Communications protocol Defines the data transfer mechanism and telegram structure for data transfer between two communication partners. Communicationsutility, utility Configurable autonomous functions with one or several access possibilities to data interfaces (e.g. message system). A communications utility consists of one or several function blocks. Compiling * When compiling from the charts of a chart folder, either * a runable user program is generated, which can be downloaded into a CPU/FM 458-1 DP, * or a user library is generated, which includes block types generated from charts. Also refer to: Consistency check, Loading Connector Break point in the CFC chart and connecting point to the block with reference to the I/O to be connected. Connectors are used if connecting lines cannot be drawn due to too much information on the sheet. Complex CFC structures (extending over several sheets) can be completely represented using the connectors. Also refer to: Interconnection, Block I/O Consistency check Checks the complete data of a chart container for errors without generating code which can be executed. Also refer to: Compilation Coupling Refer to coupling module Coupling module Module with memory or direct access to memory (rack coupling) on which a SIMADYN D CPU can save or retrieve net data to be transferred. Coupling modules are all coupling memories, all firmware modules (including the carrier modules) and the rack-coupling modules. Also refer to: Data interface Coupling partner Glossary - SIMATIC D7-SYS Edition 12.2004 Partner in SIMADYN D, with which data can be exchanged via a data interface, but where it cannot be processed. These can include sender, receiver or coupling modules. G-5 Glossary Also refer to: Channel, Communications partner Coupling type Designates the coupling, e.g. SINEC H1, rack coupling, DUST 1. Also refer to: Coupling module CPU Module, on which an open-loop/closed-loop control program is executed. A SIMADYN D station can have a maximum of 8 CPUs. CPU local coupling A coupling whose data interface is available locally on the the SIMATIC TDC/SIMADYN D CPU/FM 458-1 DP. Also refer to: Coupling module CPU number The CPUs in a SIMADYN D station, which are consecutively numbered from left to right. Creation mode Operating mode of the CFC, in which blocks are inserted, deleted, renamed, parameterized or interconnected. Also refer to: Test mode Cross reference Elements in the margin of a CFC chart, which refers to a interconnection to another block on another chart sheet. Also refer to: Connector Cyclic task G-6 Task, whose processing is initiated in uniform, time intervals - its sampling time. SIMADYN D CPUs/FM 458-1 DP modules can process several cyclic tasks. Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary D Daisy-chain connector Connectors, which are used to jumper empty slots at the backplane bus of a SIMADYN D subrack, where a module is not inserted. The slots which require daisy-chain connectors can be seen in the detailed view of HWConfig. Data block (DB) Data blocks are interfaces in the user program and are used to address variables. Data blocks do not require any additional memory space. There are * instance data blocks, which are used to transfer data to WinCC, and * data blocks, which include a user data area, to realize communications with SIMATIC-OPs. Data consistency For interconnections and $ signals between different cyclic tasks, D7SYS guarantees that all of the transferred data are consistent. This means that data, transferred from a task Ti, are taken from the same computation cycle of this task. If a signal is to be transferred without deadtime, it is possible to bypass data consistency ($ signal, "Fast" type or by interconnecting with a pseudocomment DATX). Also refer to: Process image Data interface Permanently structured memory medium (e.g. dual port RAM), which two coupling partners can access to transfer data. The structure defines how the data interface is configured (e.g. where general initialization data are deposited, the data memory size and what is still available). The data interface structure is the same for all couplings. The contents of the data interface structure are of no importance for the user, because when configuring couplings, memory areas do not have to be explicitly addressed. Data transfer mode Configurable data transfer mechanism for senders and receivers. Handshake, refresh, select and multiple modi can be selected. Senders and receivers must have the same configured data transmission mode; otherwise, they will not be able to synchronize with one another and exchange data. Also refer to: Channel Data type Each I/O of a block is assigned a particular data type. It defines the value range, resolution, display and interpretation of values at this input or output. "BOOL" defines, for example, a binary variable, "INT" defines a 16-bit fixed-point variable. DATX If a connected block input is to receive its values from a connected output, bypassing the data consistency mechanisms, then it must be marked with a pseudocomment "@DATX". Also refer to: Data consistency Delay time Glossary - SIMATIC D7-SYS Edition 12.2004 When synchronizing the basic clock, the delay time between the initiating process interruptand when the cyclic tasks is started. This time can be configured. G-7 Glossary Diagnostics buffer The diagnostics buffer is a buffered memory area for CPU/FM 458-1 DPmodules CPU, which is structured as a ring buffer. Diagnostic events are saved in the sequence in which they occurred. Diagnostics event A diagnostics event makes an entry into the diagnostics buffer of the CPU/FM 458-1 DP. A differentiation is made between diagnostics events as follows: * Errors while initializing ("0" or IF-LED) * Monitoring errors ("b" or MF-LED) * Communication errors ("C" or CF-LED) * Task administration errors ("E" or TF-LED) * User errors ("A" or UF-LED) (with function block USF diagnostics event defined by the user) * Operating mode transitions (e.g. from RUN to STOP) Diagnostics interface Serial interface at the front panel of a SIMADYN D-CPU module. This interface permits local access to this CPU with the CFC in the test mode for troubleshooting, testing and start-up. Display device Display devices are used in order to intervene in the process and display the current process status. $ signal A $ signal is used to interconnect function blocks, which run on different CPUs within the same SIMADYN D station. When configuring a $ signal, its signal name as well as type and bus assignment must be specified. The $ signal type determines whether data transfer is to be consistent ("standard") or should bypass the data consistency mechanisms ("Fast"). The bus assignment defines which of the two backplane buses are used for data transfer. Also refer to: Global operand, Virtual connection, Data consistency Dynamic value display, dynamic update G-8 Displays the current values at the block I/O in the CFC in the test mode. The displayed values are continuously updated. The configuring PC must in this case access the automation unit via a communications link. Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary E Enable attribute Equivalent sampling time The enable attribute is a run-time attribute. It activates and de-activates a run-time group. While de-activated, the group is not executed, independent of all other conditions. When you interconnect a block output, data type BOOL with the run-time group, the value of this block output then decides as to whether the group is activated or de-activated. Contrary to cyclic tasks, interrupt tasks are not started at equidistant time intervals, but when a process interrupt occurs. Certain function blocks (e.g. control blocks) are configured so that they are called-up at regular time intervals. If these are to be configured in an interrupt task, then an equivalent sampling time must be configured in HWConfig. for this interrupt task. This should correspond to the average time between two consecutive process interrupts. If the basic clock is not generated by an internal clock generator, but from a process interrupt, or if it is synchronized to the basic clock of another CPU (basic clock synchronization), then an equivalent sampling time can be specified for the basic clock. Also refer to: Sampling time Error field Errors/faults related to the hardware, operating systems and the user program are recorded in the error field of a CPU/FM 458-1 DP. In the test mode of the CFC, this error field can be read-out and analyzed for diagnostics. Exception buffer In the exception buffer of a CPU/FM 458-1 DP (this is not available for type T400 CPUs) when goes into the STOP condition, information is recorded, which permits the error cause to be identified. The exception buffer can be read-out and analyzed in the test mode of the CFC. The contents of the exception buffer are retained, even if a subrack is reset, or is isolated from the power supply, under the assumption, that a battery is inserted in the subrack. Expansion module Peripheral module to input and/or output process signals such as analog-, digital inputs/outputs or speed sensing signals. When connected directly to a CPU board, bypassing the backplane bus they relieve the backplane bus and allow process signals to be sensed at extremely high data rates. A maximum of two expansion modules can be inserted to the right of aplanned for that module. Glossary - SIMATIC D7-SYS Edition 12.2004 G-9 Glossary F FBSLIB This is a standard-block library included in the scope of supply of the D7SYS option package. It includes over 200 block types to realize most of the open-loop and closed-loop control tasks. Also refer to: System library Firmware Software which is to be configured on a coupling module, e.g. CSH11, but not using D7-SYS configuring resources. A firmware converts the net data from the data interface into a telegram corresponding to the particular communications protocol. Flag Flags are used in D7-SYS as address information at block I/O. SIMATIC Operator Panels can access the block I/O via these flags. Also refer to: Global operand Function block (FB) Pre-configured block types from Siemens which are saved in a system library. Also refer to: Block G-10 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary G Generic block Block, where the number of inputs can be changed by appropriate parameterization. Also refer to: Block type Global operand Global operands are objects which can be addressed from function blocks. For D7-SYS software, these are: $ signals, virtual connections, hardware addresses, virtual connection information as well as name references. Also refer to: Interconnection, OP connection Glossary - SIMATIC D7-SYS Edition 12.2004 G-11 Glossary H Hardware address Symbolic designation of one or several terminals which are functionally associated with one another on a module. The hardware address is defined in HWConfig. The terminal can be addressed in the CFC under this designation. Also refer to: Global operand Hardware catalog HWConfig window, from which the configurable hardware objects (subrack, modules and submodules) can be copied into a station. Also refer to: SIMADYN D station HWConfig G-12 Configuring tool to define the hardware configuration of the automation units in a user-friendly fashion; for example,. SIMATIC TDC/SIMADYN D stations. Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary I Initialization value An initialization value can be specified at block outputs. This value is at the output, if the block is calculated for the first time in the INIT operating status. It may be necessary and practical to specify an initialization value, if: - an output is connected to the input of a block, which is executed first, or - the status of the block output defines the internal status of the block (e.g. the Q output of a flipflop block). Also refer to: Run-time properties, Parameters (1) Input/output module, I/O module Peripheral module to input and/or output process signals. Instance When a block is instanced, this ensures that the instance of the block type (block) can run in its configured environment. Instance data block Using an instance data block, display devices can access block I/O. An instance data block is automatically generated in the CFC and is permanently assigned to a block. Interconnection Connecting a block output or block input with another element: * Block output - block input * Block output - global operand * Block output - run-time group * Global operand - block input The value of the connected input is retrieved from the other end of the connection during the run-time. Interface The interface comprises interconnectable and parameterizable I/O of a block (block interface) or a chart (chart interface). Interface module Communications submodule, on which one or several communication protocols are implemented. Also refer to: Communications protocol Interrupt synchronization Synchronizes the interrupt tasks of several CPUs, so that a process interrupt, which is identified on a CPU, can initiate that an interrupt task is executed on several CPUs. Also refer to: Basic clock cycle synchronization Interrupt task Glossary - SIMATIC D7-SYS Edition 12.2004 An interrupt task is a task which is executed by a process interrupt. G-13 Glossary L L bus One of the two backplane busses of a SIMADYN D subrack. Also refer to: C bus Loading General term for online load and offline load. Load-relevant change A change in the CFC chart is relevant as far as loading is concerned, if it results in a change in the user program on the CPU/FM 458-1 DP (e.g. modified interconnection). Changes which are not relevant for loading are, for example, block positions and comments. G-14 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary M Maplisting The maplisting contains additional information about a user program (the type of blocks used, reference lists of the $ signals and the virtual connections, expected computation time of the CPU, ...). It is generating when compiling the charts of a CPU/FM 458-1 DP if the "create map listing" option switch is enabled in the dialog extras: settings > compilation. Margin Margin on the lefthand and righthand side of a sheet. The margins contain, on one hand the cross-references to a connected object (block, run-time group, global operand) which is not located on the actual sheet. It also includes the number of the connector, if the autorouter cannot draw the connecting line to the margin due to an overfilled chart. Memory module Check-card format memory module which is used as program memory for a SIMATIC TDC/SIMADYN D CPU or FM 458-1 DP. The operating system, user program and change memory of the CPU are saved in the memory module. SIMADYN D memory modules conform to the PCMCIA standard, memory modules for the FM 458-1 DP are MMC cards. Also refer to: Sub-module Module name The module name at a communications module defines which coupling module is used for data transfer. When configuring the (fixed or optional) network, all module names must be precisely 6 characters long, and the 6th character must correspond to a specific convention. Also refer to: Global operand MPI address In an MPI network each node must be assigned its own MPI address. Multiple insertion For the SIMATIC S7 and SIMATIC M7 target systems, a function block can be incorporated in several tasks. This is not possible for SIMADYN D. Also refer to: Run-time properties Multi Point Interface (MPI) The multi-point interface is the SIMATIC TDC/SIMADYN D and SIMATIC S7-400 service interface. CPUand FM 458-1 DP-Modules can be handled from a central location. Display devices can be connected to the multi-point interface. The nodes in an MPI sub-network can communicate with one another. Multiprocessing By being able to multiprocess, SIMADYN D can distribute the solution to technology tasks over several user programs, and run on several CPUs. Glossary - SIMATIC D7-SYS Edition 12.2004 G-15 Glossary N Name reference Name of a message system. Central block, message entry- and message evaluation blocks of a message system are connected with one another via this name. Also refer to: Global operand Nested chart A CFC chart, which is inserted in another CFC chart (nested chart or top chart) just like a block. Contrary to a real block, a nested chart can be opened. Nested charts are not visible in the SIMATIC Manager. Net A net connects net nodes (stations) through a connecting cable to establish a communications network. Net data Values which are transferred from the sender to the receiver. The net data do not contain information regarding the type, sequence or contents of the quantities to be processed. Also refer to: Channel Net data buffer, buffer Part of a channel, in which net data is transferred. Configuring engineers do not have access to this area. Net data structure Information about the structure of the net data to be transferred. The net data structure describes the quantity and type of net data. Also refer to: Data type, Sequence number Network The network provides the user with transparent data transfer extending beyond subrack- and communication protocol limits. A differentiation is made between the freely selectable network and the fixed network. Network transition Transition between sub-networks of a complete network. It can involve the transition between (sub) networks with difference characteristics (e.g. transition between Profibus and Industrial Ethernet). G-16 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary O Offline For offline, there is no data connection between the automation system and the configuring PG/PC. Offline loading Loads the user program and operating system of the SIMATIC TDC/SIMADYN D CPU or FM 458-1 DP into the memory module, which is inserted for this purpose into a corresponding slot in the configuring PGs/PCs or external Prommers. Also refer to: Online loading Online For online, there is a data connection between the automation system and the configuring PG/PC.

There are three sub-sets of the statuses in the STOP operating mode: Sub-status 7-segment or LED display Behavior User stop 'd'/STOP-LED on Can be accessed online via the diagnostics interface and all configured service interfaces. Stop after initialization error '0'/IF- and STOP-LED on Can be accessed online via the diagnostic interface and initialization interface. Stop after fatal system error 'H'/ INTF- and STOP-LED on Can be accessed online via the diagnostics interface. Operating system This is a collective term for all of the functions, which control and monitor the execution of user programs, the distribution of operating resources to the individual user programs and maintain the operating mode in conjunction with the hardware. Operator Panel (OP) Display device to make an intervention at the machine, e.g. enter setpoints, output machine data. Operator Station (OS) An operator station is used to make interventions in the process and to display the current process status. Generally, an operator station comprises a PC with software for operator control- and visualization functions (HMI). Overflow sheet An overflow sheet is automatically set-up, if the number of margin entries on a sheet means that there is no more space. An overflow sheet only consists of the margins and does not contain other objects. Overview mode View in the CFC, where all six sheets of a chart partition are displayed.

Registration, registration database Essential configuring data of STEP 7 configuring tools are stored in the registration database of Windows. Refer to the online help for Windows when you run into problems with the registration database. Reorganization Re-formatting a data interface during operation. The coupling is inhibited for a positive edge at the connection of a central block, its data interface is re-formatted and the coupling is then re-enabled. Also refer to: Network Repeater Coupling element to connect two segments of a sub-network. Run-time properties The configuring engineer defines the run-time properties of a block by assigning it to a task or run-time group and defining the position within the task or run-time group. These characteristics are decisive for the behavior of the target system regarding response times, deadtimes or the stability of time-dependent structures, e.g. control loops. Run-time group Run-time groups structure and sub-divide tasks. The blocks are sequentially integrated into the run-time groups. Run-time groups can be separately activated and de-activated. If a run-time group is de-activated via a block output which is connected to it, all of the blocks, contained in the run-time group, are no longer activated. Also refer to: Run-time properties, Interconnection G-20 Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary S Sampling time The sampling time of a cyclic task is the time interval between two task calls. The sampling times must be to the power of 2 of the basic sampling time. SAVE area Battery-buffered memory area of SIMATIC TDC/SIMADYN D CPU (not available for type T400 CPUs) or FM 458-1 DP, where data is kept even during a power failure, under the assumption that a battery is inserted in the subrack. Configuring data can be saved in a non-volatile fashion in the SAVE area using special function blocks. Scaling factor Factor, which can be configured at the block I/O data type REAL. The parameter values are therefore computed, internally normalized (per unit), but are displayed as absolute value. For drives, the scaling factor is also known as "nominal value" or "rated quantity".

Glossary - SIMATIC D7-SYS Edition 12.2004 G-21 Glossary Symbol A symbol is a user-defined name which observes specific syntax rules. This name stands for a variable and is used for operator control and monitoring. Symbol table The symbol table is used to assign symbols to variable addresses (e.g. flags). System charts Several CFC charts, in which specific system responses of a SIMADYN D CPU are configured (7-segment display control, handling the acknowledge button, ...). The system chart is automatically available in a D7-SYS-program contained in an again put on modul and may not be deleted Also refer to: Chart folder System exception signal If a SIMADYN D CPU identifies a fatal system error, it goes into the STOP condition, and informs the other modules in the station using a system exception signal. Another module can ignore this system exception signal, and continue to operate, or it can also go into the STOP condition. Also refer to: Exception buffer System exception message TDC If a SIMATIC TDC module identifies a critical system fault/error, then it goes into the STOP operating mode. It then sends a system exception message to the first CPU of the station. As a response, it can be defined as to whether the remaining modules in the station continue to operate or the complete station should go into the STOP condition. Also refer to: Exception buffer System library G-22 A block library supplied by Siemens. Glossary - SIMATIC D7-SYS Edition 12.2004 Glossary T Target system The automation system or a component of it on which the user program runs, is known as the target system. Target systems are, for example, SIMATICS S7, M7 and SIMADYN D. Task The sequence in which the user program is processed is defined in the tasks. Also refer to: Run-time properties, Interrupt task, Cyclic task Task manager The task manager coordinates the execution of tasks, corresponding to their priority.

Data in the TSAVE area, contrary to the SAVE area, is kept until it is explicitly deleted (with the appropriate command in the download dialog box). Glossary - SIMATIC D7-SYS Edition 12.2004 G-23 Glossary U Units, units text Text, which can be configured for a module I/O, in order to assign physical dimensions to values at this I/O (e.g. m, kVA). Also refer to: Scaling factor Update cycle In the test mode this specifies in which time intervals the block I/O, which are to be monitored, are updated. User data area User data areas are used to transfer data between SIMATIC TDC/SIMADYN D or FM 458-1 DP and SIMATIC-OP. The data areas are written into and read from the operator panel and the user program. By evaluating the data saved there, the user program and operator panel initiate defined actions. User library A block library generated by the user himself. User program The user program includes all instructions and declarations as well as data for signal processing which can be controlled by a system or a process. It is assigned a programmable module (e.g. CPU, FM).
