I have an error on a cpu 1214. On diagnosis I got the message "Module exist. faulti. faulty led (SF) and the error led is blinking .When I make a hardware download the error stops. If I switch off the power supply and switch on again, The error appears again. Any idea what is wrong. Thank you ------------------------------------------------------------------------------------------ |

Whatever is shown in the diagnostics buffer entry for the faulty device at PLC startup needs to get powered up before the PLC so when the PLC starts up, it's there and available.
