Dear Experts We are using S7 1200 PLC with analog input module with following specifications. CPU 1215 C DC/DC/DC - 6ES7 215-1AG31-OXBO Version V 3.0 AI Module - SM 1234 - 6ES7 234 -4HE32-OXBO - V2.0 Some times PLC goes to stop mode with analog input 0 , high limit exceeded. When we force the PLC to run mode through TIA , it goes to run mode. The fault buffer enclosed for your reference. We did the following, but the problem did not solve. 1. Changed the PLC start up mode to Warm Restart - RUN 2. Added OB of diagnostic error interrupt and Hardware interrupt. Kindly sugget any other settings needs to be done to avoid PLC goes to stop mode. Regards Prian

Hi, still ur plc goes to stop mode after unchecking the overflow and underflow diagnostic check box?? Check for high limit exceeding in your sensor ... you can delete the diagnostic error OB ..since it used used to detect the errors caused by below description There are two types the errors that could be detected by the user program: 1 - Detection and report of peripheral device errors from diagnostics-capable devices. for more info pls read the below post posted by pegaia for more info https://support.industry.siemens.com/cs/document/42781105?dti=0&lc=en-WW |
