TIA Portal programming

In this typical circuit diagram, the focus is on the safety-related switching of the machine.
Therefore, operational switching is not taken into account, and no standard user program is
programmed. In this example, the user must implement the operational switching – adapted
to the conditions of the machine – in their program with the aid of the "operativeOn" variable
in the DB "DataToSafety" via the FB "StartStop".

The MainSafety function block is called cyclically by an F-runtime group. This contains all
other safety-related program parts.
