Important notes

Observe the following instructions when using the Profiler.

Notice

Changed time behavior of the IEC program when using the Profiler functionalities

The Profiler measurements change the runtime behavior of the IEC program. The effects depend on the PLC program architecture and the Profiler configuration.

Notice

Watchdog exceptions when using the Profiler functionalities

The Profiler measurements change (slow down) the runtime behavior of the IEC program.
Watchdog exceptions may occur.

You should therefore only use the profiler functions in a secure test environment.

	Change Profiler settings via download Switching the profiling function on and off and changing the Profiler configuration will force a download. It is not possible to load these changes to the controller using Online Change.

	Libraries TwinCAT can only record calls to the application code of the current PLC project, the referenced libraries remain unnoticed! If you want to record calls from libraries, you can encapsulate these calls in actions in the application code. You can then record these actions.
