Verifying the Download/Online Change Success

The verification is done via upload of a *.log file from each PLC where all operations are logging their success or failure. For diagnostic purposes these *.log files are not deleted afterwards. They are stored in the installation directory of the Automation Builder.

If the button Show Results is pressed the contents of the selected PLC log file is displayed.

After starting the download/online change the PLC tab is active and will indicate the success of the operation at the end by using different colored lines:

• GREEN: All successfully done.
• ORANGE: The download was done, but there were diagnostic errors, e.g. configuration faults or run time errors ““ need to look at the .
• RED: Perhaps the PLC is offline, the IP address is wrong or the project has a wrong target (so download will be rejected immediately). In these special cases there is no detail information available because a log file could not be uploaded.

Note

In this case a look into the CODESYS V2.3 log files can be helpful. They are generated each time (overwriting the logs from the last session) CODESYS is started in batch mode and can also be found in the Automation Builder installation directory.

• “MultiDownloadDiag.msg” is the log file for multi download operation.
• “LoadFirmwareDiag.msg” is the name of the log file of the firmware update operation.
• “OnlineChangeDiag.msg” is the name of the log for the online change operation.
