6.5 RecoBus Diagnosis
For RecoBus diagnosis, the MTS-R provides a double word for input
information (%ID*.0). This double word serves to display error and status
information. It is represented to the user in the PLC I/O editor on Byte 0-3.
This double word should always be a part of the PLC user program, thus
allowing quick reactions to error messages of the RecoBus.
