Hi, we are using F-IO system with S7 414 H system MLFB of installed system are 6ES71951GC000XA0 6ES74070DA010AA0 6ES74174HL010AB0 6ES79601AA000XA0 6GK74431EX110XE0 6ES71570AA820XA0 6ES71532BA000XB0 6ES73325HD010AB0 6ES73411CH010AE0 6ES73361HE000AB0 6ES73261BK000AB0 6ES73262BF010AB0 Redundant module keep functioning but SF is generated. In order to remove SF, module needs to be removed from base and Power recycle to AI/DI/DO module. attached event log is for event which happened on 27th June. Event is random, sometimes repeats in a week sometimes in a year. Same module functions absolutely normal after power recycle and removal from base. Mystery needs to be resolved !! Please help. If needed, PLC backup can be shared to debug further. ------------------------------------------------------------------------------------------ AttachmentDiagnose cpu.zip (232 Downloads) |
