1 Application description The application below shows how to read and write parameters in the SIMATIC Manager by means of the S7 standard function blocks SFB52 and SFB53. The application includes the following sample projects:

Example 01: Read error buffer of SINAMICS G120 CU240S PN via PROFINET Example 02: Read parameters from SINAMICS G120 CU240S PN via PROFINET Example 03: Write parameters into SINAMICS G120 CU240S PN via PROFINET Example 04: Read parameters from SINAMICS G120 CU230P-2 PN via PROFIBUS Example 05: Write parameters into SINAMICS G120 CU230P-2 PN via PROFIBUS Example 06: Write parameters into SINAMICS G120 CU240S via PROFIBUS Example 07: Read parameters from the IM of the ET200pro FC via PROFIBUS Example 08: Read parameters from the IM of the ET200S FC via PROFIBUS Example 09: Read parameters from the MICROMASTER 420 via PROFIBUS Example 10: Read parameters from the MICROMASTER 440 via PROFIBUS

By means of the PROFINET sample projects 01, 02 and 03 reading and writing parameters is explained in detail step by step. The error buffer of the Control Unit CU240S PN is read-out in example 01: Parameter r0947 – last error message and parameter r0949 – error value. In example 02, individual parameters of the Control Unit CU240S PN are read-out - such as firmware version (r0018), frequency setpoint (r0020), frequency actual value (r0021), output voltage (r0025), output current (r0027) and others (a total of 23 parameters). Parameter P1082 (maximum frequency) is written to in example 03. The parameter value is changed from the default value of 50.00 Hz to 100 Hz. The possibility of controlling the frequency inverter is realized in all three examples. In Chapter 2 of the application you will obtain an overview of the components being used (hardware and software components). In Chapter 3 information is provided as to how you can connect all of the Ethernet nodes (devices connected to Ethernet) in PROFINET. Here you will be shown how you assign IP addresses and PROFINET names to PROFINET nodes (devices connected to PROFINET). In Chapter 4 a description is provided on how you can create the hardware configuration of the network in the SIMATIC Manager (HW Config). In Chapters 5, 6 and 7 a description is given on which blocks you require to read and write parameters - and how you create these. A description is also provided on how you can control the read / write process. Information and instructions are given in Chapter 8 on reading and writing parameters of PROFIBUS-capable CUs of the SINAMICS G120 and SINAMICS

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".

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).

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.

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.

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).

6.2.2 Example 1: Controlling the drive (network 1 of OB1)

Control word 1 (STW1) and the main setpoint (HSW) are sent to the drive via the PROFINET interface. 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.

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).

NOTE For MICROMASTER 4 and SINAMICS G120 frequency converters with Control Units CU240S up to firmware version V3.2x and ET200S FC / ET200pro with V3.x only two codes are used for the format:

- 42: for all unsigned16 and integer16 ( = 16 bit, single word) parameters,

- 43: for all unsigned32, integer32 and floating point ( = 32 bit, double word) parameter.

For SINAMICS G120 frequency converters with Control Units CU230P-2, CU240B-2 and CU240E-2 from firmware version V4.2 and higher, codes for the format should be used according to the subsequent table.

7.1.4 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.

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.

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.

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).
