Hi. We're a used machinery merchant. We have all sorts of machines through our shop. We currently have a tube bender that's not working correctly. It has a Mitsubishi A172SHCPUN PLC. The PLC is in Run mode but it also has the Error LED lit - see photo. We're hoping that getting rid of the Error LED will cajole it into working correctly.
I know very little about Mitsubishis, basically just enough to get an upload. We're using GX Developer v8.1. When I go to Diagnostics/PLC Diagnostics it says there is no error - see capture.
When I got an upload, there was an error that mentioned the comments being bad - is this relevant? Another dialog popped up at the end of the upload too (see captures) but that didn't seem to be anything to worry about.
Can anyone assist in finding why the Error LED is lit and then eliminating the error?
