The CM 1542-5 allows the connection of an S7-1500 station to a PROFIBUS fieldbus system. As an alternative, the CM can be operated in the following modes: Class 1 DP master DP slave Supported communications services In its current configuration, the CM 1542-5 communications module supports the following communications services: PROFIBUS DP master (class 1) - DP master according to EN 50170, DP-V1 - DP master mode for DP slaves according to PROFIBUS DP-V0 and DP-V1 - DP master mode for Siemens DP slaves - Direct data exchange (DP slave to DP slave) As a DP master, the CM 1542-5 is capable of enabling direct data exchange for its assigned DP slaves. - SYNC/FREEZE The outputs or inputs can be synchronized by the user program using system function DPSYNC_FR. PROFIBUS DP slave DP slave according to EN 50170, DP-V0 / DP-V1 Note DP master or DP slave The CM only supports operation either as DP master or DP slave. FDL The CM handles the FDL communication using program blocks of Open User Communication (OUC) see section Configuration, programming (Page 27). CM 1542-5 12 Operating Instructions, 11/2018, C79000-G8976-C290-04 Product overview, functions 2.3 Further functions S7 communication - PG communication for uploading / downloading of S7 configuration, diagnostics and routing - Operator control and monitoring functions (HMI communication) - Data exchange over S7 connections Data record routing / field device parameter assignment You can use the CM as a router for data records intended for field devices (DP slaves). Data records from devices that are not connected directly to PROFIBUS and therefore have no direct access to the DP slaves are forwarded to the DP slaves by the CM. The services of the CM 1542-5 listed above can be used independently at the same time. Note Requirement for FDL, data record routing, loading of configuration/diagnostics data For the functions FDL, data record routing and loading configuration and diagnostics data the CM must either be operated in the mode DP master mode or as a DP slave with the option "Test, Commissioning and Routing" enabled. 2.3 Further functions Enabling /disabling DP slave - in the standard system DP slaves can be activated and deactivated by the user program using system function D_ACT_DP. Diagnostics requests As a DP master (class 1), the CM 1542-5 supports diagnostics requests of a DP master (class 2). Getting the bus topology in a DP master system The CM 1542-5 operating as DP master supports the measurement of the PROFIBUS bus topology in a DP master system using a diagnostics repeater (DP slave). System function DP_TOPOL in the user program can instruct diagnostics repeaters to measure the PROFIBUS BUS topology in a DP master system. CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 13 Product overview, functions 2.4 Configuration limits and performance data Time-of-day synchronization - time master or time slave The CM 1542-5 can be enabled for time-of-day synchronization. As an alternative, the CM can be configured as time master or time slave on PROFIBUS. Time master: The CM is synchronized using the time of day in the S7-1500 station and outputs the time of day on PROFIBUS. The output interval can be set. Time slave: The CM receives time-of-day frames on PROFIBUS and outputs the time within the S7-1500 station. The output interval within the S7-1500 station is set permanently to 10 seconds. Note Recommendation for setting the time It is advisable to set the time-of-day master so that time-of-day frames are sent at intervals of approximately 10 seconds. This achieves as small a deviation as possible between the internal time and the absolute time. Web diagnostics With the aid of Web diagnostics of the CPU, you read the diagnostics data from an S7 station via the Web browser on the PG/PC. In terms of the CM, the Web pages provide the following information: Module and status information Special information on the DP master system (status of the DP slaves) 2.4 Configuration limits and performance data 2.4.1 Configuration limits - number of CMs When using the CM type described here, the following limits apply: The number of CMs that can be operated in a rack depends on the CPU type being used.

I/O devices (for example, PC adapter 6ES7972-0CB20-0XA0) are therefore not operational on the interface). 3.4 Mode of the CPU - effect on the CM You can change the mode of the CPU between RUN and STOP using STEP 7 or the switch. Depending on the operating status of the CPU, the CM behaves as described below. Changing the CPU from STOP to RUN Programmed connections are established. In DP master mode: - Change from CLEAR to the OPERATE mode In DP slave mode: - Going diagnostics interrupt to the master - Current input data is transferred. Changing the CPU from RUN to STOP The reaction is as follows in STOP: Programmed connections are terminated. In DP master mode: Change to the CLEAR mode In DP slave mode: - Input data is sent to the DP master with the value "0" and a DP diagnostics alarm is sent. Regardless of the mode, the following functions remain enabled: - The configuration and diagnostics of the CM Relevant system connections for configuration, diagnostics and PG channel routing still exist. - Data record routing - S7 routing function - Time-of-day synchronization - Configured connections remain established.

You will find the required version in the section Project engineering (Page 18). You will find complete information on configuration in the STEP 7 information system. Loading and saving the configuration data When you load the station, the project data of the station including the configuration data of the CP is stored on the CPU. You will find information on loading the station in the STEP 7 information system. 4.2 Program blocks for communication and distributed I/O Program blocks (instructions) for communications services For communications services, there are preprogrammed program blocks (instructions) available as the interface in your STEP 7 user program. Table 4- 1 Instructions for PROFIBUS DP System blocks and system functions Meaning when used with CM DPSYC_FR DP slaves synchronize / freeze inputs (SYNC/FREEZE instruction) DPNRM_DG Reading the diagnostics data of a DP slave DP_TOPOL Detecting the topology for the DP master system WRREC Writing the data record of a DP slave RDREC Reading the data record of a DP slave GETIO Reading the process image of a DP standard slave SETIO Transferring the process image of a DP standard slave GETIO_PART Reading the process image partition of a DP standard slave SETIO_PART Transferring the process image partition of a DP standard slave D_ACT_DP Disable / enable DP slaves DPRD_DAT Reading consistent data of a DP standard slave (user data) CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 27 Configuration, programming 4.3 Program blocks for FDL System blocks and system functions Meaning when used with CM DPWR_DAT Writing consistent data of a DP standard slave RALRM Event-driven reading of interrupt information (diagnostics, pull/plug, hardware interrupt) and DPV1-specific interrupts (update, status, vendorspecific interrupt) Refer to the documentation of the program blocks in the information system of STEP 7. Calling program blocks (instructions) for distributed I/O Several calls are necessary for the instructions of the distributed I/O. The time required to process the job depends on load, round-trip time and transmission speed. If these instructions are called in a loop within one cycle, the cycle time could be exceeded. Exception: Only one call is required for RALRM "receive alarm". Program blocks for DPV1 according to the PNO standard (PROFIBUS user organization): RDREC "Read data record from a DP slave" corresponds to SFC59 in terms of function WRREC "Write data record to a DP slave" corresponds to SFC58 in terms of function RALRM "Read interrupt information from a DP slave" - call in an interrupt OB 4.3 Program blocks for FDL Program blocks of Open User Communication (OUC) for FDL To use the bus access protocol FDL (Fieldbus Data Link) use the program blocks of Open User Communication (OUC). For this, create a suitable program blocks. You will find details on the program blocks in the information system of STEP 7. The end point of an FDL connection is an S7-1500 CPU with communications module CM 1542-5. For the required firmware versions of the modules, see section Programming (Page 18). CM 1542-5 28 Operating Instructions, 11/2018, C79000-G8976-C290-04 Configuration, programming 4.3 Program blocks for FDL Supported program blocks for OUC The following instructions in the specified minimum version are available for programming Open User Communication to use FDL: TSEND_C V3.1 / TRCV_C V3.1 Compact blocks for connection establishment and for sending and receiving data via a configured or programmed connection or TCON V4.0 / TDISCON V2.1 Connection establishment / connection termination TSEND V4.0 / TRCV V4.0 Sending or receiving data over a configured connection TUSEND V4.0 / TURCV V4.0 Sending or receiving data over a configured connection With these blocks the connection parameters can be changed at runtime. The program block can be found in STEP 7 in the "Instructions > Communication > Open User Communication" window. Connection description of the type "TCON_FDL" To reference the connection description, the blocks "TCON" and "TSEND_C / TRCV_C" use the CONNECT patrameter. The connection description is stored in a data block whose structure is specified by the system data type (SDT) "TCON_FDL". Creating an SDT for the data block You create the SDT required for every connection description as a data block. You generate the SDT type in STEP 7 by entering the name ("TCON_FDL") in the "Data type" box manually in the declaration table of block instead of selecting an entry from the "Data type" drop-down list. The SDT is then created with its preset parameters. For FDL the following SDTs are used: TCON_FDL For transferring data via FDL You will find the description of TCON_FDL in the STEP 7 information system (keyword "TCON_FDL"). Programmed connection establishment or termination with TCON / TDISCON Connections are established using the program block TCON. Note that a separate program block TCON must be called for each connection. A separate connection must be established for each communications partner even if identical blocks of data are being sent. CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 29 Configuration, programming 4.3 Program blocks for FDL After a successful transfer of the data, a connection can be terminated. A connection is also terminated by calling "TDISCON". Note Connection abort If an existing connection is aborted by the communications partner or due to disturbances on the network, the connection must also be terminated by calling TDISCON. Make sure that you take this into account in your programming. Configured and programmed FDL connections The following types of FDL connections can be established: Configured FDL connections These connection types are configured in the STEP 7 program editor, see below. TSEND / TRCV or TUSEND / TURCV are used as the blocks. - Specified connection Fully configured connection between two partners - Unspecified connection Configured connection with an unspecified partner - Broadcast connection Connection with all connected partners - Multicast connection Connection with several defined partners Programmed FDL connections These connection types cannot be configured in the STEP 7 program editor. Instead for these connection types either calling TCON along with TSEND/TRCV or TUSEND/TURCV is required or TSEND_C / TRCV_C. - Specified connection Fully configured connection between two partners - Unspecified connection Configured connection with an unspecified partner - Unspecified Layer 2 connection Programmed FDL-Verbindung with an unspecified partner with free layer 2 access - Broadcast connection Connection to all connected partners - Multicast connection Connection to several defined partners CM 1542-5 30 Operating Instructions, 11/2018, C79000-G8976-C290-04 Configuration, programming 4.3 Program blocks for FDL The specific settings for the individual connection types are explained in the STEP 7 information system in TCON_FDL. Setting up a configured FDL connection using TSEND_C Proceed as follows to set up a configured FDL connection in STEP 7: 1. Create a TSEND_C instruction in the program editor. You will be prompted to create the relevant data block. 2. Select the TSEND_C instruction and navigate in the Inspector window to "Properties" > "Configuration" > parameter group "Connection parameters". 3. In type of configuration, select "Use configured connection" 4. In connection type, select "FDL". 5. Under End point, select the partner end point. Use one of the two following partner end points. - CPU S7-1500 with CM 1542-5 - Unspecified 6. Select the following interfaces under Interfaces: - Local: PROFIBUS interface of CM 1542-5 - Specified partner: PROFIBUS interface of CM 1542-5 7. Select the setting <new> under Connection data. This creates a new connection between the two partners. The figure below shows a fully configured FDL connection in STEP 7. Figure 4-1 Configuring the FDL connection 8. Configure the further block parameters. CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 31 Configuration, programming 4.3 Program blocks for FDL Setting up a programmed FDL connection using TSEND_C To set up a programmed FDL connection in STEP 7, follow the steps below: 1. Create a TSEND_C instruction in the program editor. You will be prompted to create the relevant data block. 2. Program the block parameters. Interconnect the CONNECT parameter of the TCON instruction with the previously created variable "FDL_Connection" of the data type TCON_FDL. The FDL connection is established and used for sending and receiving data. Setting up an FDL connection in the user program For programmed communication via FDL, you need to create and program the data block of the system data type TCON_FDL yourself and call it directly at the instruction. Follow these steps: 1. Create a global data block in the project tree. 2. In the global data block create a variable of the data type TCON_FDL. The following example shows the global data block "FDL_connection" with the variable "FDL_connection" of the data type TCON_FDL. Figure 4-2 Programming an FDL connection 3. In the data block program the parameters of the FDL cconnection, e.g. the PROFIBUS addresses. The type of connection is specified with the "ServiceId" parameter. You will find details in the STEP 7 information system. 4. Create a TCON instruction in the program editor. 5. Interconnect the CONNECT parameter of the TCON instruction with the previously created variable "FDL_Connection" of the data type TCON_FDL. In the example below, the CONNECT parameter of the TCON instruction is interconnected with the tag "FDL_Connection" (data type TCON_FDL).

To narrow the error/fault down even further, evaluate the message on the display of the S7-1500 CPU. If errors/faults occur, you can also identify them using the Web server or by evaluating the diagnostics buffer of the CPU. The diagnostics buffer of the CPU contains plain language information about the error/fault that has occurred. The diagnostics buffer is accessible via STEP 7, the display and the Web server. For information on the LED displays, refer to the section LEDs (Page 19). STEP 7: The "Diagnostics" tab in the Inspector window Here, you can obtain the following information on the selected module: - Entries in the diagnostics buffer of the CPU - Information on the online status of the module STEP 7: Diagnostics functions in the "Online > Online and diagnostics" menu Here, you can obtain static information on the selected module: - General information on the module - Diagnostics status - Information on the PROFIBUS interface You can obtain further information on the diagnostics functions of STEP 7 in the STEP 7 online help. DP diagnostics The DP diagnostics of the CM is described below. The evaluation of diagnostics data records requested by the DP master and the diagnostics interrupts or diagnostics alarms of the DP slaves is handled in the user program of the DP master station. CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 35 Diagnostics and upkeep 5.2 DP slave diagnostics 5.2 DP slave diagnostics DP-V1 slave: Diagnostics interrupt The diagnostics data is transferred as a diagnostics interrupt. Diagnostics interrupts must be acknowledged by the DP master. Supported diagnostics functions The CM 1542-5 supports the following blocks of DP diagnostics: Standard diagnostics (6 bytes) Identifier-related diagnostics (2 to 17 bytes), depending on the number of configured transfer areas Module status (5 to 35 bytes), depending on the number of configured transfer areas If it exists: Diagnostics interrupt (8 bytes) User program (DP master) To read out the diagnostics data of the DP slave (DP single diagnostics), use the "DPNRM_DG" instruction on the DP master. Diagnostics interrupts of DP-V1 slaves are evaluated in the user program of the master using the "RALRM" instruction. You will find the required parameter assignment for the instructions in the STEP 7 online help. Below, there is an overview of the structure of the diagnostics data. Overview of standard diagnostics Standard diagnostics Byte Meaning 0 Station status 1 1 Station status 2 2 Station status 3 3 Master address 4...5 Vendor ID of the slave CM 1542-5 36 Operating Instructions, 11/2018, C79000-G8976-C290-04 Diagnostics and upkeep 5.3 Standard diagnostics Overview of device-specific diagnostics The device-specific diagnostics data depends on the protocol variant operating on the DP slave: DP-V1 slave Table 5- 1 Overview of device-specific diagnostics of the CM with DP-V1 slaves Device-specific diagnostics Byte Meaning 0 Header 1 Variant Interrupt type 2 Slot number 3 Variant Interrupt specifier 4...62 5.3 Variant Status type Variant Status specifier Module-specific diagnostics data Standard diagnostics The coding of the standard diagnostics bytes is explained below. Byte 0: Station status 1 Table 5- 2 Structure of station status byte 1 Bit no. Name Explanation 7 Master_Lock The DP slave was assigned parameters by a different DP master. The DP slave can only be read by the configured productive DP master. This bit is set by the DP master when its bus address differs from the configured address. 6 Parameter_Fault The last received parameter assignment frame was bad or not permitted. The DP slave sets this bit. Solution: Check the parameter settings for illegal parameters. 5 Invalid_Slave_Response This bit is set by the DP master when no plausible response has been received from the DP slave. 4 Service_Not_Supported This bit is set by the DP master when the master has requested a function that is not supported by the DP slave. Solution: Change the parameter setting to disable the function on the master. 3 Ext_Diag This bit is set by the slave. * Bit =1: There is diagnostics data in the slave-specific diagnostics area. The diagnostics data can be evaluated in the user program of the master. * Bit =0: There may be status information in the slave-specific diagnostics area. The status information can be evaluated in the user program of the master. CM 1542-5 Operating Instructions, 11/2018, C79000-G8976-C290-04 37 Diagnostics and upkeep 5.3 Standard diagnostics Bit no. Name Explanation 2 Slave_Config_Check_Fault The configuration data sent by the DP master is rejected by the DP slave. 1 Station_Not_Ready The DP slave is not ready for productive data exchange. 0 Station_Non_Existent The DP slave is not reacting on the bus. Cause: Configuration error. Solution: Change configuration. This is a temporary status that cannot be influenced by the DP master. This bit is set by the DP master 1 (the slave sets this bit permanently to 0). If the bit is set, the diagnostic bits have the state of the last diagnostics alarm or the initial value. Byte 1: Station status 2 Table 5- 3 Structure of station status byte 2 Bit no. Name Explanation 7 Deactivated The DP slave was identified as being not active in the local parameter record and it is not polled cyclically. 6 Reserved - reserved - 5 Sync_Mode The DP slave is in SYNC mode. The bit is set by the slave. 4 Freeze_Mode The DP slave is in FREEZE mode. The bit is set by the slave. 3 Watchdog_On Watchdog monitoring is active on the DP slave. The bit is set by the slave. 2 Status_From_Slave Bit =1: The diagnostics information comes from the DP slave. The bit is set permanently to 1 by the slave. 1 Static_Diag Static diagnostics If the DP slave sets this bit, the DP master must fetch diagnostics data from the DP slave until the DP slave resets the bit. The DP slave sets this bit, for example when it is not capable of data transfer. 0 Parameter_Request The DP slave sets this bit when it needs to have new parameters assigned and be reconfigured. If bit 0 and bit 1 are both set, bit 0 has the higher priority. Byte 2: Station status 3 Table 5- 4 Structure of station status byte 3 Bit no. Name Explanation 7 Ext_Data_Overflow If this bit is set, there is more diagnostics information available than indicated in the diagnostics data.

If the DP slave did not have parameters assigned to it by any DP master, the DP slave sets the address 255 in this byte. Bytes 4 and 5: Vendor ID of the slave ("Ident_Number") The vendor ID ("Ident_Number") for the DP slave type is entered in bytes 4 and 5. This identifier can be used to identify the slave. The more significant part of the value is in byte 5. 5.4 Device-specific diagnostics in DP-V1 There are two variants of device-specific diagnostics with DP-V1 slaves: Interrupt type Status type The two variants differ from each other in the coding of byte 1, bit 7 of the device-specific diagnostics data. The difference is component-specific. Byte 0: Header The two most significant bits have the value 00. This identifies the "module-specific diagnostics data" field (see bytes 4... 62) as a whole. The remaining six bits indicate the length of the data field including byte 0.
