Illustration 23: The Deactivation of the SS2 Request Before the Function is Reached. Acknowledgment: Automatic.
The automatic acknowledgment occurs when the SS2 request ends.
When there are safety functions that can be acknowledged by manual acknowledgment and safety functions that cannot (if, for
example, they are requested), a manual acknowledgment signal deactivates the functions that can be acknowledged. Functions
that could not be acknowledged continue their execution normally.
