Configuration options The following configurations, each with value status, are possible: Without HART variables in the input area With 8 HART variables in the input area With a multiHART range in the input/output range When configuring is done in HW Config, the configuration is carried out indirectly in the parameter assignment dialog of the module. Note Only the listed configurations can be directly configured for the I/O module while the CPU is in RUN mode. To set another configuration, first remove the I/O module in CPU RUN. You then add the I/O module with the new configuration while the CPU is in RUN mode. Please note that this might change the I/O address area. Parameters You define the functioning of the I/O module via parameters. The parameters are subdivided into: Module/channel parameters (data record 128) Parameters that determine the display of HART variables in the address space of the module; HART mapping parameters (data record 130) System parameters (potential group, IO redundancy) See also Parameter assignment and structure of the module/channel parameters (Page 45) Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 13 Parameters 4.2 Module/channel parameters 4.2 Module/channel parameters Parameters of AI 16xI 2-wire HART HA You have the following setting options: Table 4-1 Parameters and their default settings Parameter Value range Default Parame ter reas signment in RUN Efficiency range Diagnostics, Missing supply voltage L+ Enabled Enabled Yes Module IO redundancy None None Yes Module Use potential group of the left module No Module Yes Channel Current (2-wire transducer) Current (2-wire transducer) 0 to 10 mA 4 to 20 mA HART Yes Channel Enabled Yes Channel Enabled Yes Channel Enabled Yes Channel Enabled Yes Channel Enabled Yes Channel Enabled Yes Channel Disabled 2 modules Potential group Use potential group of the left module Allow new potential group Measurement type Measuring range Disabled 0 to 20 mA 4 to 20 mA 4 to 20 mA HART There is no underrange in the ranges 0 to 10 mA or 0 to 20 mA That is, the smallest analog value is zero.

See also Parameter assignment and structure of the module/channel parameters (Page 45) Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 15 Parameters 4.3 Explanation of the module/channel parameters 4.3 Explanation of the module/channel parameters Diagnostics, Missing supply voltage L+ Enabling of the diagnostics for missing or insufficient supply voltage L+. IO redundancy You can configure two identical modules redundantly. To do so, plug both modules into a redundant terminal block side by side. You can find additional information on mounting modules in an IO redundancy configuration in the ET 200SP HA System Manual, section "Installing", "Installing terminal block". In IO redundancy mode, the left module is the master and the right module is the slave. Both redundant modules measure simultaneously and independently in the process. Both redundant modules generate diagnostics, alarms and process values. The process values are based on the measured values of the respective leading channel that measures with low resistance in the process. By default, the channels of the master are the leading channels. When a module fails or when the failure of a channel is detected, the respective leading channels are switched over to the partner module. Once an error has been corrected, there is no changeover of the leading channels involved. HART communication can only take place over the leading channel. Measurement type/measuring ranges The I/O module supports the following measuring ranges: Measurement type Measuring range Resolution for interference frequency suppression 10 Hz Disabled Current (2-wire transducer) 50 Hz 60 Hz -- -- -- -- 0 to 10 mA 15 bits plus sign 15 bits plus sign 14 bits plus sign 0 to 20 mA 15 bits plus sign 15 bits plus sign 15 bits plus sign 4 to 20 mA 4 to 20 mA HART The resolution of the analog values is dependent on the interference frequency suppression setting. HART mode is only possible with a measuring range of 4 to 20 mA. HART communication is not interrupted even at currents below 4 mA. An overview of the measuring range and the overflow, overrange, etc. can be found in section Configurations of the AI 16xI 2-wire HART HA I/O module (Page 13). Diagnostics encoder supply The sensor supply of the analog input is monitored for overload and short-circuit to M. 16 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB Parameters 4.3 Explanation of the module/channel parameters Diagnostic short-circuit to L+ Enabling of the monitoring for a short-circuit of the analog input to sensor supply or L+. The short-circuit and overflow diagnostics can be activated at the same time. If both diagnostics occur simultaneously, the short-circuit diagnostics is output. Diagnostics, Wire break You can enable a wire break diagnostics for measuring range 4 to 20 mA or 4 to 20 mA HART. The diagnostics are output when the current flow falls below the assigned wire break limit. The wire break and underflow diagnostics can be activated at the same time. If both diagnostics occur simultaneously, the wire break diagnostics is output. Diagnostics overflow Enabling of the diagnostics when the measured value exceeds the overrange. Diagnostics underflow You can enable a underflow diagnostics for measuring range 4 to 20 mA or 4 to 20 mA HART. The diagnostics are output when the measured value falls below the underrange. There is no underrange in measuring ranges 0 to 20 mA and 0 to 10 mA. Diagnostics HART Enabling of the diagnostics of the HART frame-specific monitoring and the status information supplied by the connected field device in the HART frame (HART device status). The HART diagnostics are signaled as maintenance events. Wire break limit You use this to specify the current limit for detecting wire breaks. If the current falls below the configured wire break limit, the measured value is declared invalid and, if wire break diagnostics is enabled, corresponding diagnostics information is generated. The value status of the analog input is set to "bad". With a wire break limit of 3.6 mA, the measured value becomes invalid when the current falls below 3.6 mA and is marked as valid again when it rises above 3.8 mA. There is no hysteresis for a wire break limit of 1.185 mA. Smoothing The individual measured values are smoothed by filtering. Smoothing can be set in 4 levels. Smoothing time = number of module cycles (k) x cycle time of the module. The following figure shows the number of module cycles after which the smoothed analog value approaches 100%, depending of the smoothing setting. This applies to every signal change at the analog input. Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 17 Parameters 4.3 Explanation of the module/channel parameters [ [ [ [ 0RGXOHF\FOHV N No smoothing (k = 1) Weak (k = 4) Medium (k = 8) Strong (k = 16) Figure 4-1 Smoothing of the analog value Interference frequency suppression Suppresses the interference that is caused by the frequency of the alternating voltage network used. When HART operation is activated, an interference frequency suppression of 10 Hz is recommended so that the HART signal does not influence the analog value. Number of HART frame repetitions Specifies the number of HART frame repetitions. If AI 16xI 2-wire HART HA does not receive a response or receives a faulty response to a HART frame sent to the field device, the frame is repeated, i.e. resent to the field device, according to this setting. Hardware interrupt 1 / 2 Enabling of a hardware interrupt when the high limit 1 /2 is exceeded or the low limit 1 / 2 is fallen below. Low limit 1 / 2 Specify a threshold which triggers a hardware interrupt when violated. High limit 1/2 Specify a threshold which triggers a hardware interrupt when violated. 18 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB Parameters 4.3 Explanation of the module/channel parameters Potential group A potential group consists of a group of adjacently placed I/O modules within an ET 200SP HA station that are supplied using a common supply voltage. A potential group begins with a light terminal block via which the needed supply voltage for all I/O modules of the potential group is fed. The light-colored terminal block interrupts the selfassembling voltage buses to the left neighbor All other I/O modules of this potential group are plugged into dark terminal blocks. I/O modules on dark terminal blocks take the potentials of self-assembling voltage rails from the left neighbor. A potential group ends with the dark terminal block that is followed by a light terminal block or a server module in the station configuration. You can find additional information on the configuration of the potential group in the system manual SIMATIC; Distributed I/O System; ET 200SP HA.

You can find additional information about hardware interrupts in appendix "Hardware interrupts (Page 56)". Diagnostics interrupts Diagnostics interrupts are used by the I/O module to signal diagnostics messages as well as maintenance events, see also appendix Diagnostics messages and maintenance events (Page 51). The I/O module generates a diagnostics interrupt at the following events: Overtemperature Channel/component temporarily unavailable Short-circuit / overload of sensor supply Wire break Low limit violated (underflow) High limit violated (overflow) Supply voltage missing Hardware interrupt lost Module is faulty Short-circuit of an analog input to sensor supply or L+ Retentive memory in carrier module defective Retentive memory in the terminal block defective Redundancy partner has different hardware/firmware IO redundancy warning Redundancy parameter assignment inconsistent HART communication error HART field device error Note The diagnostics "Module is defective" and "Excess temperature" are not cleared again by the module without a restart. 24 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART function 6 Definition "HART" stands for "Highway Addressable Remote Transducer". Using the HART functionality, you can exchange data between the I/O module and the connected field devices. The HART protocol is generally accepted as a standard protocol for communication with intelligent field devices: HART is a registered trademark of the HART Communication Foundation (HCF), which owns all the rights to the HART protocol. You can find detailed information about HART in the HART specification. Advantages of HART Use of the AI 16xI 2-wire HART HA gives you the following advantages: Connection compatibility with standard analog modules: Current loop 4 - 20 mA Additional digital communication via the HART protocol, HART communication (Rev. 5 to Rev. 7) Numerous field devices with HART functions are in use I/O module enables application of HART devices on an IO device based on ET 200SP HA Use in the system The I/O module is used in an IO device based on the ET 200SP HA. You can connect a HART field device to each channel (monodrop mode). The I/O module serves as HART master, the field devices as HART slaves. The maximum 16 channels communicate in parallel.

HART signal The figure below shows the analog signal with the modulated HART signal (FSK method), which consists of sine waves of 1200 Hz and 2200 Hz and has a mean value of 0. It can be filtered out using an input filter so that the original analog signal is available again. +0,5 mA 0 -0,5 mA 1200 Hz 2200 Hz "1" "0" 20 mA 1 K A K A K A A K 4 mA 0 2 Figure 6-1 The HART signal Time (seconds) K Command A Response Analog signal HART communication The I/O module processes the HART communication in parallel operation, that is, all channels simultaneously. With enabled HART operation, the I/O module automatically sends HART commands to the connected field devices. These commands always alternate with any pending external HART 26 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART function 6.1 How HART works commands for the specific channel that arrive via the command interface of the module, see section HART command interface (Page 61). Commissioning a HART field device Only HART field devices that have been set to short frame address 0 can be operated. If a HART field device with a different short frame address is connected or a connected field device is reconfigured to a short frame address other than 0 during operation, the module starts a scan of all possible short frame addresses at the next re-establishment of HART communication (command 0 with short frame addresses 1...63). As soon as the connected field device responds, it is converted to the short frame address 0 (HART command 6) by the module. The I/O module signals a HART communication error during the scan. HART commands The configurable properties of the HART field devices (HART parameters) can be set with HART commands and read out using HART responses. The HART commands and their parameters are divided into three groups with the following properties: Universal Common practice Device-specific Universal commands must be supported by all manufacturers of HART field devices and common practice commands should be supported. There are also device-specific commands that apply only to the particular field device. Examples of HART commands The following two tables show examples of HART commands: Table 6-1 Examples of universal commands Command Function 0 Reads manufacturer and device type - only with this command 0 can field devices be addressed by means of a short frame address 11 Reads manufacturer and device type 1 Reads primary variable and unit 2 Reads current and percentage of range, digitally as floating-point number (IEEE 754) 3 Reads up to four pre-defined dynamic variables (primary variables, secondary variables, etc.) 13, 18 Reads or writes process tag name ("tag"), description and date (dates are also sent) Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 27 HART function 6.1 How HART works Table 6-2 Examples of common practice commands Command Function 36 Sets high range limit 37 Sets low range limit 41 Perform self-test 43 Sets the primary variable to zero Structure of the HART protocol Each HART frame sent from the I/O module to the connected field device (request frame) and each HART frame received by the field device (response frame) has the following basic structure. PREAMBLE PREAMBLE: STRT: ADDR: COM: BCNT: STATUS: DATA: CHK: STRT ADDR COM BCNT STATUS DATA CHK Bytes (0xFF) for synchronizing, default: 5 bytes (can be changed using DS131 - DS138) Start character (start delimiter) Address of the field device (1 byte; short address or 5 bytes; long address) HART command number Byte count, number of bytes to follow without checksum HART device status (1st and 2nd status byte). Only present for a response frame. For structure of HART device status, see below. Transferred user data / parameters, quantity depending on command (0...230 bytes) Checksum With the exception of the preamble bytes, this structure is contained in the communication data of the HART command interface. See section HART job and response data records (Page 63). HART responses always contain data. Status information (HART device status; 1st and 2nd status bytes) is always sent together with a HART response. status bytes) is always sent together with a HART response. You should evaluate these to make sure the response is correct. 28 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART function 6.1 How HART works Structure of HART device status (1st and 2nd status bytes) Table 6-3 1st status byte Bit 7 = 1: "Communication error" Bit 6 = 1 Bit 5 = 1 Bit 4 = 1 Bit 3 = 1 Bit 2 = 0 Bit 1 = 1 Bit 0 = 0 Parity error Overflow Framing error Checksum error Reserved Overflow in the receive buffer Reserved Bit 7 = 0: "No communication error" Bit 0...6: "Specific according to the response frame" Table 6-4 Bit 7 = 1 Bit 6 = 1 Bit 5 = 1 Bit 4 = 1 Bit 3 = 1 Bit 2 = 1 Bit 1 = 1 Bit 0 = 1 2nd status byte Device fault Configuration changed Startup (cold start) Additional status information available Fixed analog output current setting Analog output current saturated Secondary variable outside the limits Primary variable outside the range HART fast mode The I/O module supports the processing of HART commands as an SHC string ("Successive HART Command"). If a HART command with set SHC bit is detected by the I/O module for a channel, this channel is reserved for external HART commands for approximately 2 s. Internal HART commands are not issued, see section HART command interface (Page 61) Burst mode The I/O module does not support burst mode. HART commands with set burst bit are ignored and are not forwarded to the connected field device.

Both assume the function of a "client": The parameter assignment tool affects the entire I/O module; the HART handheld is connected in parallel to the field device. PDM (Process Device Manager) is available standalone or integrated in STEP 7 HW Config. In the latter case, PDM is opened from HW Config. HART system integration: The I/O module takes on the function of a "master" by receiving commands from the HART parameter assignment tool, for example, forwarding them to the smart field device and sending back the responses. The interface of the I/O module is made up of data records that are transmitted internally via the ET 200SP HA IO device between IM and I/O module. The data records must be created and interpreted by the client. )LHOGGHYLFHZLWK+$57IXQFWLRQDOLW\ +$57DQDORJPRGXOH ,QWHUIDFHWR 352),1(7,2 P$ /9 0RGHP +$57+DQGKHOG $'8 6HQGUHFHLYH RI+$57VLJQDO $QDORJGLJLWDOFRQYHUVLRQ RIF\FOLFPHDVXUHGYDOXH 6,0$7,& 3'0 +$57SDUDPHWHU DVVLJQPHQWWRRO 0*URXQG Figure 6-2 30 System environment for the use of HART Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART function 6.2 HART applications Error management The two HART status bytes (HART device status) that are transferred with every response of the field device contain error indications regarding the HART communication, HART command and device status. These are evaluated by the I/O module and made available in the system using S7 maintenance messages. Configuration/commissioning How to configure the I/O module with HW Config You assign parameters for the individual channels with regard to the actual analog value acquisition and the use of HART variables in the input address space of the module. You can configure one field device per channel. The configuration/parameter assignment of the connected field device is then carried out from this configured field device using PDM or the EDD for the ET 200SP HA. Parameter reassignment of the field devices The I/O module generally accepts triggered parameter reassignments for field devices. The awarding of access rights can only be made in the parameter assignment tool. To reassign parameters of the field devices connected to the I/O module, proceed as follows: 1. You initiate parameter reassignment of a field device with a HART command that you enter with the SIMATIC PDM parameter assignment tool. 2. After you complete parameter reassignment of a HART field device, the corresponding bit is set in the HART device status of the connected field device (in the 2nd status byte). 3. As a result of field device reconfiguration, the I/O module triggers a "Configuration changed" maintenance message if such a message is enabled. This maintenance message should be regarded as a notice and not an error. It is automatically deleted again by the I/O module after approximately 1 minute. If enabled, a maintenance message can also be triggered by a new parameter assignment with the handheld device. See also Pin assignment of the AI 16xI 2-wire HART HA I/O module (Page 9) Diagnostics messages and maintenance events (Page 51) Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 31 HART function 6.3 HART variables 6.3 HART variables Introduction Numerous HART field devices make available additional measured quantities (e.g. sensor temperature). A maximum of four HART variables supported by the connected field device are read cyclically for each channel with enabled HART functionality. The HART variables are read automatically via the HART command 3 (for field devices with HART Rev. 5 and 6) or via command 9 (for field devices with HART Rev. 7 or later). These four HART variables per channel are always stored in HART variable data record 121 and can be read at any time. In addition, you can optionally configure the following: You can map a maximum of 8 HART variables to the input address space of the I/O module. The HART variables are assigned to a channel in the properties dialog of the I/O module. This allows you to easily process measured values directly from the field device as input data in the automation device. You can configure a multiHART area in the input/output address space of the I/O module. You can read all HART variables available in the I/O module with each of these multiHART areas. You specify the multiHART area in the properties dialog for the I/O module. Address assignment Each HART variable occupies 5 bytes of input data. As soon as you configure (map) at least one HART variable in the input address space, the addresses for all 8 tags are assigned (40 bytes). When the multiHART area is used, an additional 6 bytes of input address space and 1 byte of output address space are assigned. Configuration of HART variables You can configure up to 8 HART variables in the properties dialog of the I/O module. You select these from the four HART variables provided by each channel: PV (Primary Variable) SV (Secondary Variable) TV (Tertiary Variable) QV (Quaternary Variable) When HART mode is enabled, the I/O module cyclically reads the variables provided by the connected field devices itself and makes them available in the configured input address space. Configuring of a multiHART area You can use a multiHART area for the AI 16xI 2-wire HART HA I/O module. You select whether or not to use a multiHART area in the properties dialog of the I/O module. 32 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART function 6.3 HART variables When HART mode is enabled, the I/O module cyclically reads the variables provided by the connected field devices itself. You can request and read one of these HART variables via the multiHART range. Quality code The quality code describes the process status of the corresponding HART variable.

If you do not plan to operate outside the PCS 7 environment, you do not need the information in the appendix. Tasks of the driver and diagnostics blocks (driver blocks) In process control systems, certain demands are placed on the diagnostics/signal processing. This includes the monitoring of modules, DP/PA slaves and DP master systems for malfunctions and failures. To enable this, blocks are available in the PCS 7 library that implement the interface to the hardware including test functions. These blocks perform two basic tasks: They provide signals from the process to the AS for further processing. They monitor modules, DP/PA slaves, and DP master systems for failure. When the process signals are read in, these blocks access the process image input (or process image partition) (PII) and when the process signals are output, they access the process image output (or process image partition) (PIQ). Concept The concept of the driver and diagnostics blocks for PCS 7 can be characterized as follows: The separation between user data processing (CHANNEL blocks) and diagnostics data processing (MODULE blocks) The symbolic addressing of the I/O signals The automatic generation of the MODULE blocks by CFC Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 41 Drivers, parameters, diagnostics messages and address space A.1 Concept of the driver and diagnostics blocks This block concept supports all modules from the list of approved modules. When new Siemens or non-Siemens module types are integrated, the meta-knowledge for the driver generator can be extended by additional XML files (object and action lists). Note Note the following: The library with the driver blocks has to installed using the Setup program on the PC. This is the only method of ensuring that the meta-knowledge required for the driver generator is available. You must not copy the library from another computer. You can also use driver blocks from another library (for example, your own blocks from your own library). You can specify this additional library in the "Generate module drivers" dialog box. The driver generator then searches for the block to be imported in the library specified here. If the block is not found here, it is searched for in the library specified in the control file (XML file). If the S7 program contains a signal-processing block but not from one of the PCS 7 libraries, you have to specify the version of the driver library from which the driver blocks are to be imported in the "Generate module drivers" dialog box. Time-optimized processing To enable time-optimized processing during runtime, the organization blocks for error handling (for example, OB85, OB86) are automatically divided into runtime groups and the driver blocks are integrated in the corresponding runtime groups. If an error occurs, the SUBNET block, for example, activates the relevant runtime group, the RACK block or MODULE block contained in the runtime group detects the error, evaluates it and outputs a process control message to the OS. The diagnostics information of the module block (OMODE_xx output) is also transferred to the corresponding CHANNEL block (MODE input). If necessary, this information can be displayed by means of a PCS 7 block that can be operated and monitored on the OS or by means of a user block in a process picture (color change of the measured value or flashing display, etc.). 42 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB Drivers, parameters, diagnostics messages and address space A.2 Parameter assignment A.2 Parameter assignment Parameter assignment in the user program You can reconfigure individual channels of the I/O module and HART variable mapping in RUN without this affecting the other channels. Changing parameters in RUN The parameters are transferred to the I/O module with the instruction "WRREC". Module/channel parameters using data record 128 HART mapping using data record 130 The parameters assigned with STEP 7 are not changed permanently in the CPU, which means the parameters assigned with STEP 7 are valid again after a restart. Output parameter STATUS If errors occur when transferring parameters with the "WRREC" instruction, the module continues operation with the previous parameter assignment. The STATUS output parameter contains a corresponding error code. The STATUS output parameter is 4 bytes long and is configured as followed: Byte 1: Function_Num, general error code Byte 2: Error_Decode, location of the error code Byte 3: Error_Code_1, error code Byte 4: Error_Code_2, manufacturer-specific extension of the error code Module-specific errors are displayed via Error_Decode = 0x80 and Error_Code_1 / Error_Code_2.

The DIAG LED on the module flashes. There is additionally a channel-specific display of the diagnostics through the corresponding channel fault/channel status LEDs. The diagnostics messages can, for example, be read out in the diagnostics buffer of the CPU. Diagnostic messages are assigned either to one input on a channel-specific basis or to all inputs as a module message.

Interrupt OBs are called automatically if an interrupt occurs. You can find detailed information on the event in the hardware interrupt organization block with the "RALRM" instruction (read additional interrupt information). The module generates a hardware interrupt at the following events: Violation of the low limit 1 Violation of the high limit 1 Violation of the low limit 2 Violation of the high limit 2 The module analog input (channel) that has triggered the hardware interrupt is entered in variable OB40_POINT_ADDR in the start information of OB40.

Irrespective of the diagnostics enables, each value status (each QI bit) provides information on the validity of the corresponding process value. Value status = 1: Process value okay, "good" Value status = 0: Process value not okay, "bad" Basically, the value status is set to "good" when the analog value can be acquired without error. The value status is set to "bad" in the following cases: The analog value cannot be acquired due to an error. The analog input is disabled. Address space The following tables show the allocation of the address space of the I/O module. Addresses for the HART area are only available if HART variables or a multiHART area were configured in the properties dialog of the module.

The structure of the HART area is dependent on the configuration: In the configuration with 8 HART variables in the input area, the area has a length of 40 bytes and always contains 8 HART variables, each with a 4-byte value and a 1-byte quality code (QC).

QB x Command multiHART range Evaluating HART variables If you have configured (mapped) HART variables for the I/O module, then 8 HART variables with 5 bytes each are stored in the input address space. Each HART variable consists of a 4-byte real value and a 1-byte quality code. The quality code describes the validity of the value, see section HART variables (Page 32). 58 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB Drivers, parameters, diagnostics messages and address space A.7 Address space The assigned HART variables are automatically updated by the module and can be used directly in the user program. Evaluating the multiHART area You can select the multiHART area in the parameter assignment dialog. The multiHART range occupies 1 byte in the output range (command) and 6 bytes in the input range (1 byte acknowledgment + 5 bytes HART variable). You can read all HART variables available in the module using the multiHART area. To do so, you must use the command byte in the output area to request a HART variable from the module. The command byte identifies the requested HART variable (HART variable reference): HART variable reference Bit 0...3: Bit 4...7: Variable identifier Channel number 0...15 1 = Primary 2 = Secondary 3 = Tertiary 4 = Quaternary The command is acknowledged via the acknowledgment byte in the input range. As soon as the HART variable reference requested using the command can be read, the requested HART variable can be evaluated. If you leave the command byte of the multiHART range unchanged, the module will continuously update the corresponding HART variable. If an invalid HART variable reference is requested, this is also acknowledged accordingly. The value of the corresponding HART variable is then zero and the quality code is signaled with 0x37H (initialization value of the analog module). Example: The primary variable is to be read from channel 6. Command = 61 H Acknowledgment == 61 H ? <HV 1R Evaluate quality code and if applicable variable Figure A-6 Command = 0x61 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 59 Drivers, parameters, diagnostics messages and address space A.7 Address space 60 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART operating data records B.1 B HART command interface Data records The HART commands are sent as so-called external HART requests from the client (e.g. PDM) to the connected field device using data records. The response of the field device is provided again in the system using data records. The HART communication may only be handled by one client per channel. If a channel is handled by several clients, the response made available by the I/O module cannot be allocated to one client with certainty. The I/O module does not support client management. Rules After having written a request data record, a client must read the response data record before it may write another request data record. The client can evaluate the "processing status" in the response data record: If the "processing status" indicates "successful" or "error," the response data record contains current response data or error indications, respectively. The response data record must always be read completely because the I/O module may modify the data record after the initial reading with "successful" or "error" status. If the processing status in the response data record indicates "successful" or "error", the data record contains current response data or error displays. The client may only write a request data record to the I/O module again when it has read the response to the previously written request data record via the corresponding response data record. Otherwise, the response from the I/O module is overwritten. The STATUS component in the response frame (HART device status in the response data) provides information on whether errors have occurred and, if so, which errors. Each request is stored on a channel-specific basis, and the corresponding request data record is locked. Another writing of the same request data record is thus not possible and is acknowledged with BUSY. The lock of the request data record is reset after the termination or completion of the requested HART command. SHC sequence If a HART command with set SHC bit is sent to the I/O module, this channel is reserved for HART commands for 2 seconds. That is, no more internal HART commands are sent to the field device for this channel. For each additional HART command with SHC bit set, the I/O module reserves this channel again for HART commands for an additional 2 seconds. Command 3 or 9 for reading the HART variables starts being sent cyclically to the field device again if a HART command without a Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB 61 HART operating data records B.1 HART command interface set SHC bit is detected for this channel, or if no further command is received for the channel within 2 seconds of the previous HART command.

Errors during the transfer are indicated at output parameter STATUS of the "WRREC" or "RDREC".

The request must be sent to the connected field device via the partner module Example of HART programming (HART command interface) For HART channel 0, command 01 is to be sent in transparent message format to the HART field device with address "98 CF 38 84 F0". A positive edge at input 4.0 of a digital input module leads to the writing of the HART command. The following assumptions are made: The module address of the I/O module is 512 (200H). The data record is stored in DB80: starting from address 0.0, length of 11 bytes. In this example, DB80 (request data record for channel 0) consists of 11 bytes.

The response is always supplied in transparent message format.

As long as the processing status (byte 0 of DB81) is at 3 (waiting, executing), the response has not yet been received from the field device. As soon as the processing status changes to greater than 3, the HART request is finished. With a processing status of 4, the request finished without errors and the response data can be evaluated. With a processing status of 5, the request also finished without errors but without response data from the field device. With a processing status of 6 or 7, the request finished with errors. You can find more detailed information in byte 1 of DB81 (see table "HART group fault display") and for a HART protocol error also in byte 2 of DB81 (see table "HART protocol error during response"). 68 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB HART operating data records B.3 HART directory B.3 HART directory Structure of the HART directory Byte Meaning Comment 0 Profile Revision Number = 2, 0 (Revision 2.0) 2 Index of Client Management = 255 (not relevant) 3 Number of Clients =1 4 Number of Channels = 16 5 Write Read Index Offset = 1 (The response to a job data record is made with the data record number of the request data record + 1) 6 Index of HMD Feature Parameter = 149 7 Index of HMD Module Parameter = 255 (not relevant) 8 Start Index of Burst Buffer Area = 255 (not relevant) 9+n Index of HMD Channel Parameter (Channel n) = 131+n 9+n+4 Index of HART Client Channel Message Data = 80+(2*n) 1 Analog Input Module AI 16xI 2-wire HART HA ( 6DL1134-6TH00-0PH1) Manual, 11/2017, A5E39408968-AB The HART request data sets are not config urable.

These variables are read cyclically, provided they are supported by the connected field device. These 64 HART variables are available to be read in HART variable data record 121. Each HART variable consists of a 4-byte real value and one byte of quality code. In IO redundancy mode, the HART variables are only updated if the HART interface is on the corresponding module/channel. The channel may not be in standby mode. If the HART interface is on the partner module/partner channel, the corresponding HART variable is initialized (quality code = 0x37).

You can specify additional HART-specific settings on a channel-specific basis using data records 131...146. The parameters assigned with STEP 7 are not changed permanently in the CPU, which means the parameters assigned with STEP 7 are valid again after a restart. Every new parameter assignment of the analog module resets the HART-specific settings back to the initial values from parameter data record 128. The I/O module does not apply the HART-specific settings if there is missing supply voltage L +. If you make changes in IO redundancy mode using the HART-specific settings, these changes only apply to the addressed module or the addressed channel. There is no synchronization with the partner channel.
