File 'plc' cound not be read
I am helping a plant troubleshoot an AC500 plc using ABB Automation Builder. When they connect the laptop to the PLC they get the error message "The last online service has not been executed correctly! Service number 49, Error number: 80 File 'plc' could ot be read."
The laptop is supposed to have a current copy of the program in the PLC and has connected to the PLC in the past. Where can I find some instructions to help me identify these error codes and clear up this error? What does this error mean?
