Good day. I have attached a notepad file that contains a crash log from my PLC. This happened about 2 weeks ago and the Rockwell Software Tech told me I will probably never see it again but upgrading the firmware on the processor might help. Well, it happened again. We have run the same program for years and the processor never faulted. We have changed the process slightly and had an automation engineer come in and write new ladder logic. The automation engineer insists it is not the program because that's what the folks at Allen Bradley told him. If anyone with experience with these types of crashes might be able to shed a little light on what is going on here, I would greatly appreciate it. The software tech at Rockwell says it's a stack overflow, which also doesn't lead him to believe the processor is faulty. Thanks.
