MCP failure switches the PLC to the STOP state. If this is undesirable, OB 82, OB 86 can be
used to avoid a stop. The MCP (as PROFIBUS slave) can also be switched on and off via
SFC12.
In the event of a failure, alarm messages are not generated by the basic program.
M to N is not possible with the MCP variant.
