Siemens simatic ET 200MP - Data Record Structure

Parameter data records
B.1 Parameter assignment and structure of the parameter data records
Analog Input Module AI 8xU/I/R/RTD BA (6ES7531-7QF00-0AB0)
46 Manual, 03/2019, A5E44792324-AA
Output parameter STATUS
The module ignores errors that occurred during the transfer of parameters with the WRREC
instruction and continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
The description of the WRREC instruction and the error codes is available in the STEP 7
online help.
Operation of the module behind a PROFIBUS DP interface module
If the module is operated behind a PROFIBUS DP interface module, the parameter data
records 0 and 1 are not read back. You obtain the diagnostics data records 0 and 1 with the
read back parameter data records 0 and 1. You can find additional information in the
Interrupts section of the manual for the PROFIBUS DP interface module on the Internet
(http://support.automation.siemens.com/WW/view/en/78324181
).
Assignment of data record and channel
For the configuration as a 1 x 8-channel module, the parameters are located in data records
0 to 7 and are assigned as follows:
● Data record 0 for channel 0
● Data record 1 for channel 1
● …
● Data record 6 for channel 6
● Data record 7 for channel 7
For configuration 8 x 1-channel, the module has 8 submodules with one channel each. The
parameters for the channel are available in data record 0 and are assigned as follows:
● Data record 0 for channel 0 (submodule 1)
● Data record 0 for channel 1 (submodule 2)
● …
● Data record 0 for channel 6 (submodule 7)
● Data record 0 for channel 7 (submodule 8)
Address the respective submodule for data record transfer.
