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?
Could you describe in detail your HW in AC500?
Are you using Eth connection or TK cable with COM port?
Are you using Automation Builder 2.0 or the previous version?
However, generally this error mean that you not have the correct setting of communication between PC and CPU.
Make sure that the cpu and the PC have the same version of Codesys programs, then verify the correct set up of communication parameters.
If you have been verified the last point, you should be able to connect the cpu to the PC without problems.
Hope this help you, let us know about the results
