Hello,
In CODESYS, we changed the timestamp of symbol list file, could this cause any error? because we got an error: "Failed to retrieve symbol list from device or file."
Also, how can we retrieve the symbols using the device option instead of files?
Greetings
I would like to inform you that the possible causes for this error "Failed to retrieve symbol list from device or file"
1. The server could not access the symbol information on the device.
2. The symbols do not match between the device and the specified symbol file in the device communication parameters.
Kindly follow the below steps and let us know the result.
1. Verify that the device is capable of storing its own symbol information. Some devices do not have this capability, and a symbol file must be specified in the device communication parameters.
2. Ensure that the device communication parameters are correctly configured in the server
