Tab 'Log'dl-permalink__symbolPermalink

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

  • 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 from I/O drivers

  • Log entries from data sources

The “Log” tab also opens when you click “Open Log Page”. You can configure this as a menu command in the “Customize” dialog.

“UTC time”

_cds_icon_option_deactivated: Converts the times displayed below “Timestamp” to the local time of the development system. The conversion is based on the time zone of the operating system where the CODESYS is running. (default setting)

_cds_icon_option_activated: Displays the original time stamp of the runtime system

If you change the option, then the displayed time stamp is converted automatically.
_cds_icon_save_in_xml_file

Exports the list contents to an xml file. You can select the file name and location.

Note for error checking

For exceptions with the description ‎*SOURCEPOSITION*‎, the affected function opens in the editor by double-clicking it or by means of 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. When the affected function is protected, then the following message appears: "‎The source code is not available for <function name>‎".

If a ‎VendorException‎ is reported, then a manufacturer-specific exception error has occurred in the CODESYS runtime. Contact the PLC manufacturer for more information.
