Reaction to Profibus errors
A Profibus error (master malfunction, removal of Profibus plug, etc.) is detected when
the DP watchdog trips (normally about 100 ms if this master was not deactivated) or
because of a bus timeout (baud rate watchdog set at 10 s).
Set the reaction to the output data of the coupler in UserPrmData:
