We have two lines in our plant that have started faulting at exactly midnight every night ever since we had a power crash a couple of weeks ago. These lines run 24/7 and there is seldom time for me to get in and look at the programs...any ideas on what could be the issue before I get into the program? The faults reset with standard "program-run-rem" key switch resets, but it is annoying and both of these lines take over 12 minutes to get back up to production after even a minor fault.
