Hello,
I have been having a issue lately. It happened after a power outage of all my controllers in the plant. Once we got power back I downloaded to all of my controllers. I do have Cold Restart Memory enabled but I don't really trust it with past experiences. The day after my download at about the same time as we got power back on the previous day I got a bunch of I/O Input Failure and I/O Output Failure alarms( some are pictured below). They happen at the same time every day. My first thought is to disable the cold restart memory function. This problem is also on all my controllers not just one. This morning I did disable the cold restart memory on one of my controllers and I will update this once the time comes for testing. This is on Version 9.3, has anyone else ran into this before?
