Hello! i have H system with 2 s7-400 CPU. we had a problem with the power supply on the (4)IM-153-2, we replaced it, after this we periodically have error “Lost of redundancy at DP Slave 4”. Red indicator SF on iM-153-2 and and error in diagnostic buffer of CPU. We replaced the module (4)IM-153-2, but this did not solve the problem; the error periodically appears on the module and controller. We checked cables and connectors. Tell me possible solutions AttachmentImages.zip (357 Downloads) |
