When a monitored condition is violated, it sets the operator I.
This immediately creates an interlock:
The switching mechanism withdraws the automatic release (AR = 0).
The sequence is stopped.
A red message with the zone text appears in the HMI.
The user does not have to program anything – they only describe what must be safe,
and Selmo ensures that this condition is constantly checked.
