Tab: Log

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

Tip

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

Logger

Enables a logger for displaying its recorded events

By default, the <default logger> defined by the system is set. For example, that is the logger PlcLog for a CODESYS Control Win runtime system.

AuditLog: This logger shows all user interactions with the PLC. The user name is also logged. These are actions such as download, start, stop or set breakpoints. Failed attempts are also logged if a user is not allowed to perform certain actions.

UTC time

_cds_icon_option_deactivated.png: 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)

standard icon: Displays the original timestamp of the runtime system

If you change the option, then the displayed timestamp is converted automatically.

Note

Error checking

For exceptions with the *SOURCEPOSITION* description, 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>."

Tip

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