The SF_EnableSwitch FB processes the confirmation of the "safe mode" state via the "S_Safe-
tyActive" parameter. On implementation in an application of the safe mode without confirmation,
a static TRUE signal is connected to the "S_SafetyActive" parameter.
The S_AutoReset input shall only be activated if it is ensured that no hazardous situation can
occur when the PES is started.
