BHGStop
MCP failure normally switches the PLC to the STOP state. If this is undesirable, OB 82, OB
86 can be used to avoid a stop. The basic program has by default the OB 82 and OB 86 call.
FC5 is called in these OBs. This FC5 checks whether the failed slave is an MCP. If this is the
case, no PLC stop is triggered. Setting "MCPxStop" := TRUE causes the basic program to
deactivate the MCP as a slave via SFC 12. If the PLC does not switch to the stop state
following the failure of or a fault on the MCP, an interrupt message will be generated via the
basic program. The interrupt is deleted when the station recovers.
