hello guys, at the factory where I work has a project with an S7 1200 cpu 1214C, made by another company. the fact is that sporadically the PLC comes to a stop and the diagnostic buffer shows a failure of numbers 4171 and 4170 and refer to MMC failures, but there is no MMC on the PLC, I don't know if they were placed and removed later, I would like to know what I do to eliminate the failure, observation I have the project in hand. Thank you very much ------------------------------------------------------------------------------------------ |

Did you resolve this already by contacting Siemens Support?
