Channel-related diagnosis
Optionally, additional channel-related diagnosis information in the diagnosis telegram to the master can also
be transmitted. The generation of the channel-related diagnosis can be released in the "USER_PRM_DATA"
area. For each outstanding alarm of the input signals, 3 bytes are transmitted.
