Safety configuration
9.3 Changing the Safety Integrated mode
If problems occur during the changeover, you can find further information in the "Info"
inspector window at "General".
Note
Effects on telegram configuration
The Safety Integrated mode affects the telegram configuration because, in the Safety
Integrated plus (F-PLC) mode, different telegrams are used than in the inactivated Safety
Integrated or the Safety Integrated modes.
Telegrams that are added or changed are kept, however, as long as they are compatible
with the newly selected Safety Integrated mode.
Make sure, if applicable, that any modifications are still present following the change of mode
in the telegram configuration.
As long as you have not saved the project, you can completely undo the change of the
Safety Integrated mode by clicking "Undo" in the toolbar.
