When we connect this CP to PLC we have some MPI problems - the OP3 panels stops working (can't fint plc's MPI address). When CP is disconnected, we can't connect to PLC! (Via CP5512 adapter) I have no idea what could be wrong... br marius

CPU312C V2.0.11 312-5BD01-0AB0 CP343-1 V1.1 343-1EX21-0XE0 OP 3 V2.09 CP5512 when I disconnect CP343-1 from rack of CPU312C, then myCP5512adapter can't connect to my CPU312C but OP3 is working.
