Hi all, We have a WTP plant controlled by S7-400H redundant configuration with PS407 4A + CPU414-H + CP443-1 on rack0 and same configuration on rack1. Rack0 CPU Master, Rack1 CPU Standby. We experience following problem: Workaround 1: Switch mode selector to STOP-RUNP-RUN on Rack1 CPU, CPU refuse to go to RUN. CPU0 remain as Master and RUN mode to hold the process. I attach also the Diagnostic buffer in all CPU and CP modules. Unfortunately the original Diagnostic buffer of Rack1 CPU was erased after the Workaround 3 so I was not able the fetch the root cause. What can I do to return the Rack1 node in RUN, as normal way? I hope I was enough clear in my explanation. Any suggestion is well appreciated. Thanks. Attachmentarchive.zip (323 Downloads) |
