Good Afternoon all,
We occasionally have PLC's across site fail and when powering back up on a test bench the only fault log is "Corrupt User Memory"
My question is, to maintain a highly reliable system should the PLC be replaced or is there no issue downloading the program again and putting the PLC back in service?
The fault is not isolated to a particular PLC, just a random one occasionally failing out of many across site
Kind Regards,
Kyle Donaghy
