Hello, today I had a fault on a PLC, luckily, I was able to clear it and we could start production back up, however now I'm worried it may happen again and shut us back down. I am fairly new to PLCs and have only been working with them for a little over a month. I took a picture of the fault before I cleared it(see below). What would be the cause of the fault below and should I be worried about it reoccurring?
Thanks
