Can anyone help me, it is urgent, how to prevent the PLC from going into Stop mode if there is a profibus fault at startup.
To clarify, I have OB82, OB86 and OB122 programmed into the PLC. PLC is in RUN mode and 4 slaves are also runnuing. As soon as one slave looses the communication to the master plc 314-C2DP, I get a profibus error but the PLC is still in RUN mode, that is OK.
The problem is, if everything is turned OFF, I turn on the PLC but leave out one or more slaves, the PLC goes to STOP.
I need to prevent the PLC from going to STOP mode if there is a Profibus fault at any moment.
Can anyone help out?
