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
The parameters in data records 0 to 9 and in data record 9 are available for 1x 9-channel
configuration 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
● Data record 8 for channel 8 (reference channel)
For configuration 9 x 1-channel, the module has 9 submodules with one channel each and
one submodule for the reference channel. 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)
