Save and compile your configuration by pressing on the "Save and Compile" button. Close HW-Config. Item-ID: , Version V1.4, 01/

22 5 Preparing the project 5.1 Creating the request and response data set 5 Preparing the project The next step is to prepare the project for reading and writing the parameters of the CU240S PN - i.e. generating and/or copying all of the blocks required. All of the steps described up until now - together with those in this Chapter - apply to all of the following examples - however with some differences when reading and writing parameters. A description is provided in Chapters 5, 6 and 7 as to which blocks are required to read and write parameters and how these are generated. A description is also given as to how you control the read/write process. NOTE All of the blocks described below (OB1, DB1, DB2, DB3, DB4, SFB52, SFB53) and the variable table can be copied from the project example. 5.1 Creating the request and response data set Reading parameters is realized using a request and a response data set. Writing to parameters is realized by just using a request data set. Please proceed as follows to create the request / response data set: In the SIMATIC Manager menu press on the button "Insert -> S7 Block -> 4 Data Block". The dialog box "Properties Data Block" is displayed. Figure 5-1 Generating data blocks Assign a name to the block (e.g. DB1 and DB2). Set the block type to "Global-DB". Assign a symbolic name to the block (e.g. Request_DB to DB1 and Response_DB to DB2). Close the dialog box with "OK". Item-ID: , Version V1.4, 01/

23 5 Preparing the project 5.2 Copying SFB52 & SFB53 system function blocks Figure 5-2 Figure 5-3 NOTE Only DB1 (Request-DB) has to be generated to write to parameters. The contents of the blocks are different for all of the examples and are explained in the next Chapter. 5.2 Copying SFB52 & SFB53 system function blocks Read and write requests are sent to the Control Unit CU240S PN using SFB53 "WRREC" (write record). Responses are received from the Control Unit CU240S PN using the SFB52 "RDREC" (read record). Item-ID: , Version V1.4, 01/

24 5 Preparing the project 5.3 Generating instance data blocks This means that both SFBs are required to read parameters, but only the SFB53 when writing to parameters. The reason for this is that when reading, the read request is first sent to the CU and then the response is received back from the CU. When writing, only the write request is sent to the CU and a response is not required. Proceed as follows: Open the standard library in SIMATIC Manager. Figure 5-4 Copying system function blocks Copy blocks SFB53 and SFB52 from the "Standard Library -> System Function Blocks -> Blocks" folder if you are reading parameters or only the SFB53 if you wish to write to a parameter. Insert the copied blocks into the block folder in your project. 5.3 Generating instance data blocks Instance data blocks must be generated for SFB52 & SFB53. These instance data blocks are assigned a call for SFB52 or SFB53. Proceed as follows to generate the instance data blocks: In the SIMATIC Manager menu press on the "Insert -> S7 Block -> 4 Data Block" button. The "Properties Data Block" dialog box then opens. Item-ID: , Version V1.4, 01/

25 5 Preparing the project 5.3 Generating instance data blocks Figure 5-5 Instance data block for SFB52 Assign a name to the block (e.g. DB3 and DB4). Set the block type to "Instance DB". For every instance block select for which SFB this block is to be generated (DB3 for SFB52, DB4 for SFB53). Assign a symbolic name to the block (e.g. InstanceDB_SFB52 for DB3 and InstanceDB_SFB53 for DB4). Close the dialog box with "OK". Figure 5-6 Instance data block for SFB53 NOTE When writing to parameters, only the instance block for SFB53 has to be generated. The contents of the instance blocks are automatically generated and do not have to be changed. Item-ID: , Version V1.4, 01/

26 6 Reading parameters 6.1 Example 1: Reading-out error message (r0947) and the error value (r0949) 6 Reading parameters Two examples for reading parameters are explained in this Chapter. In the first example, the error buffer of Control Unit CU240S PN is read-out: Parameter r0947 last error message and parameter r0949 error value. In the second example, individual parameters of the Control Unit CU240S PN are read-out - such as the firmware version (r0018), frequency setpoint (r0020), frequency actual value (r0021), output voltage (r0025), output current (r0027) and others (a total of 23 parameters). The possibility of controlling the frequency inverter is realized in both of these examples. 6.1 Example 1: Reading-out error message (r0947) and the error value (r0949) In the first example, 8 indices of parameter r0947 (last error message) are read-out and also 8 indices of parameter r0949 (error value). 6.2 Example 1: Generating the request data set (DB1) to read the parameters Figure 6-1 Request data set (DB1) to read parameters Item-ID: , Version V1.4, 01/

Status word 1 (ZSW1) and the main actual value (HIW) are received from the drive. The drive is started by sending the typical control word 047E, followed by 047F (edge of bit 0: ON). In order to stop the drive, word 047E should be sent to the drive (edge of bit 0: OFF). The control word is sent together with process data word 1 (PZD1) that should be specified in the variable table VAT_1 (bit memory word MW0). Figure 6-3 Text and comments regarding the network 1 Status word 1 (ZSW1) is received from the drive (PZD1) and is transferred into the bit memory word MW4. The MW4 can be taken from variable table VAT_1. Item-ID: , Version V1.4, 01/

28 6 Reading parameters 6.2 Example 1: Generating the request data set (DB1) to read the parameters The main setpoint is sent, together with PZD2 to the drive - and the main actual value is received from the drive in PZD2. The main setpoint should be specified in the variable table VAT_1 (bit memory word MW2). The response - the main actual value - is saved in the MW6 and can be taken from the variable table. The frequency setpoint and actual value are normalized so that 4000(hex) corresponds to 50Hz. The highest value that should be sent is 7FFF. The normalization frequency (reference frequency) can be modified in P2000 (default, 50Hz).

Figure 6-6 Text and comments on network 3 NOTE Here, it is important to assign the variable ID to the PAP address from HW- Config. The length of the RECORD variable may not be greater than the length of the MLEN variable. Please use the same length for these variables Example 1: Controlling the read process The read process is controlled using variable table VAT_1. Data about how the process is proceeding, about errors that occur while processing the function, and data that have been read-out can be taken from the variable table: 1. The write request ("Read parameter") is sent to the drive using bit memory M8.0. Enter a value of 1 (true) to start the write request. The request should then be ended. Send the value 0 (false) to end the request. 2. Bit memory M8.1 indicates whether the write request is running: 1 active, 0 inactive. 3. Memory bit M14.2 indicates whether an error occurred while processing the function. 4. The bit memory - double word MD10 contains an error code. Please refer "Help on system functions / function blocks" for a description of all errors. 5. The read request is sent to the drive using bit memory M8.2. Enter a value of 1 to start the read request. Then end the request using value Bit memory M8.3 indicates whether the read request is running: 1 active, 0 inactive. 7. Bit memory M16.2 indicates whether an error occurred while processing the function. Item-ID: , Version V1.4, 01/

The length of the RECORD variable cannot be greater than the length of the LEN variable. Please use the same length for these variables Example 3: Controlling the write process The write process is controlled using the variable table VAT_1. Data about how the process is progressing, about errors that occur while the function is being processed, can be taken from the variable table: 1. The write request ("Write parameter") is sent to the drive using bit memory M8.0. Enter a value of 1 (true) to start the write request. The request should then be ended. Send a value of 0 (false) to end the request. 2. Bit memory M8.1 indicates whether the write task is running: 1 active, 0 inactive. 3. Bit memory M14.2 indicates whether an error occurred while processing the function. 4. The bit memory - double word MD10 contains an error code. Please refer to "Help on system functions / function blocks" for a description of all errors Figure 7-3 Controlling the write process Item-ID: , Version V1.4, 01/

41 8 Reading and writing parameters from/to the frequency inverters via PROFIBUS using SFB52 & SFB53 8 Reading and writing parameters from/to the frequency inverters via PROFIBUS using SFB52 & SFB53 The SFB52 & SFB53 standard S7 blocks can also be used to read and write from/to parameters of the PROFIBUS capable Control Units of the SINAMICS G120/G120D and Interface Modules of the ET200S FC and ET200pro via PROFIBUS. NOTE The structure of the data and instance data blocks as well as the procedure for their generation remains precisely the same. This means that all data and instance data blocks from the project examples can be used to read and write parameters of the PROFIBUS capable Control Unit of the SINAMICS G120/G120D and Interface Modules of the ET200S FC and ET200pro via PROFIBUS. Changes only have to be made in the HW-Config and in the OB1 organizational block of the project. Changes in HW-Config: 1. The PROFIBUS system must be configured instead of the PROFINET system: Configure the PROFIBUS interface Set-up a frequency inverter (GSD file for DP CU/IM and telegram) 2. The I/O address from HW-Config is used to transfer the DS47 parameters. Figure 8-1 Item-ID: , Version V1.4, 01/

42 8 Reading and writing parameters from/to the frequency inverters via PROFIBUS using SFB52 & SFB Reading and writing parameters of the ET200S FC and ET200pro Changes to OB1: The I/O address must be converted into the hexadecimal format and the variable ID assigned (e.g. 256 dec = 100 hex). Figure 8-2 Figure 8-3 Also read the appropriate FAQ on the subject of "Reading and writing from/to parameters of a SINAMICS G120": How can I use SFC58 and SFC to read parameters from my G120? 8.1 Reading and writing parameters of the ET200S FC and ET200pro Please carefully note that the parameters lists of the SINAMICS G120/G120D frequency inverter differ from those of the ET200S FC and ET200pro. The ET200S FC and ET200pro frequency inverters for instance, do not have parameters r1024 (actual fixed frequency), r1050 (CO: Actual output frequency of the MOP), r1242 (switch-in level, Vdc-max controller) and r1246 (switch-in level, kinetic buffering) that are read-out of the CUs of the SINAMICS G120/G120D frequency inverters in the second example. These or other parameters that are not included in the ET200S FC and ET200pro frequency inverters must be removed from the request and response data sets or replaced by other parameters. Item-ID: , Version V1.4, 01/

43 8 Reading and writing parameters from/to the frequency inverters via PROFIBUS using SFB52 & SFB Reading and writing parameters of the ET200S FC and ET200pro NOTICE If a parameter of a frequency inverter that does not exist in the frequency inverter is requested, this results in problems when reading-out parameter values. The value of the requested parameter and all values of the parameters following the parameter are then incorrectly shown. This is the reason that the second example for ET200S FC and ET200pro cannot be used. Separate project examples have been generated for ET200S FC and ET200pro frequency inverters. In this project example, the parameters that are not available have been replaced by others. A total of 24 parameters is read-out. You can take these from the following table. Parameters for MM440 and ET200S FC (table 8-4) are corresponding, in case of MM420, 18 parameters are selected (table 8-5).
