Tab ‘Log’

You can view the PLC log in this tab of the generic device editor. It lists the events that were recorded on the target system. This concerns:

  • Events during the startup and shutdown of the system (components loaded, with version)
  • Application download and loading of the boot application
  • Custom entries
  • Log entries of I/O drivers
  • Log entries of the data server

Note

The Log tab also opens when you click Open log page. You can configure this as a menu command in the Customize dialog box.

Severity

There are four categories for the severity of the event:

  • 68bf9b2ecf319b7fc0a8640e002b49b6_0b05a60ecf4d4947c0a8640e005ffc38 : information

Note

Note for error checking: For exceptions with the description \*SOURCEPOSITION\*, the affected function opens in the editor by double-clicking it or from the Display source code in editor command in the context menu. The cursor jumps to the line that is causing the error. You can also perform this diagnosis when you have the CODESYS project archive, including the download information files and the exported log file. If the affected function is protected, then the following message appears: “The source code is not available for <function name>”.
