A friend bought a used PLC based brewery which is controlled via an EZ3 (see 2nd image below) from ezautomation.net. He's not sure the source of the code on the EZ3 and when it powers up there's a "PLC1: read error" (see 1st image below). Nothing responds on the touchscreen when the error message appears.
I am not at his brewery but he sent some pictures and I agreed to post on HBT to see if anyone had any troubleshooting ideas. The seller claims the system was working correctly the last time they used it.
