engineer118 Posted June 18, 2022 Report Share Posted June 18, 2022 I have a V570 with a broken HMI (black screen) but we have proved the PLC is still operational by testing the trips it commands. Unfortunately the program is >10 years old and no records were kept. The original supplier also does not have records. I have successfully connected to the controller via USB To serial cable. Unfortunately attempting an upload was met with Warning 224 “the project cannot be uploaded because: - the option burn upload project was not selected when the project was downloaded, or - due to incomplete data in the PLC”. There is also “error - no valid upload data has been found in the PLC”. I am sure the project must have been burned into memory as we have never replaced any PLC batteries and we have an annual shutdown which would drop power to this PLC. Is there any way to get around this warning/error and get the program off the PLC? I found a password written on a drawing inside the cabinet - just wondering where I could try put this in if it is what is stopping the upload from working?
