vijayan.R Posts: 13 Rating: (0)	Dear All, We are using S7 315 F for our plant safety system. last week we faced one problem that,one of the DP station went to fault mode,we checked in the Diagnostic Buffer it is showing that Distributed IO station failure.& then it showed Distributed IO station returns. then we checked the help event , it shows that IO station power supply switched OFF/ON. but we checked physically power supply is ok & cable connections are also proper. Kindly help me out to resolve this issue... Regards, Vijayan R Attachment safety_plc_Diagnose.pdf (207 Downloads)
