TwinCAT Logged Events window

The TwinCAT Logged Events window is available from Visual Studio 2013.

The target system events can be loaded from the cache database mentioned above and displayed via the Logged Window. The window is opened in the TwinCAT 3 Engineering (XAE) via View > Other Windows > TwinCAT Logged Events.


The toolbar in the window provides the following functions:

Loads the events from the selected target system.
You can configure whether alarms or messages should be displayed via the Alarms or Messages button respectively.
The severity from which the events should be displayed can be selected via the drop-down menu.
Provides an export of the data in a CVS format, where the information that is currently displayed is exported.
Deletes (after a prompt) the cache database on the target system.
The language can be selected or entered via the drop-down menu.

The columns in the window and the temporal resolution can be configured using the commands in the context menu:

Entries can be selected via the filter function:


TwinCAT options

The TwinCAT engineering settings in the TwinCAT options (Tools > Options) provide basic settings for the TwinCAT 3 EventLogger.

Maximum number of messages displayed in the TwinCAT Logged Events window.
Output as Task Item
Display of the events in the Error List window.
The display in this window makes sense because it does not have to be loaded, but instead takes place synchronously. The display is not designed for a large number of messages, however, so this means that the option can also be used to deactivate the display if necessary.
