Table 6- 1 Switching capacity and service life of relay contacts for resistive loadThe dimensional drawing of the module on the mounting rail, as well as a dimensional
drawing with open front cover, are provided in the appendix. Always observe the specified
dimensions for installations in cabinets, control rooms, etc. The data records of the module have an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO.
Dependencies for configuration with GSD file
When a GSD file is used to configure a module, dependencies can arise when "assigning the
parameters".
There are no dependencies for this module. You can assign the individual parameters in any
combination.
Parameter assignment in the user program
You have the option to reconfigure the module in RUN (e.g. the response of selected
channels to the CPU-STOP state can be changed in RUN without having an effect on the
other channels).
Parameter assignment in RUN
The WRREC instruction is used to transfer the parameters to the module using data records
64 to 71. The parameters set in STEP 7 do not change in the CPU, which means the
parameters set in STEP 7 are still valid after a restart.
The parameters are only checked for plausibility by the module after the transferThe 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 get the diagnostics data records 0 and 1 for the read
back parameter data records 0 and 1. You can find more information in the Interrupts section
of the PROFIBUS DP interface module device manual on the The channel parameters of the module are included in data records 64 to 71 and are
assigned as follows:
● Data record 64 for channel 0
● Data record 65 for channel 1
