We have 2 redundant CPU S7-400 H, alarm from PCS7 HMI for CPU error in PLC rack 1 , Synchronization between CPU's is not bossible , PLC is runing in solo mode , Synchronization module IFM1F/2F fault . We checked the diagnostic buffer for each CPU and found theat CPU performed warm restart , the time between alarm coming and going is 1:13 minutes , diagnostic buffer is attached Visual inspection performed for PLC rack and nothing abnormal detected What is the possible causes for this failure ? And what is the action required to eliminate this issue to keep redundancy between CPU's Thanks AttachmentDiagnose buffer CPU#RACK1.zip (4 Downloads) |
