Dear Mjelban, I have some time to answer your question. FC 451 “RED_DEPA”: Initiate depassivation is described in the handbookAutomation System S7-400H Fault-tolerant Systemsplease see this handbook on page 8-14. When you replace the module then the possibility is there that with OB83 the swap of the module will initiate FC 451 and the module is working again. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
