Command Control
The Command Control function block provides the complete logic to select between three independent modes (Auto, Local
1, Local 2) based on the input signals (bus fault (internal signal), Force Local 2 and Auto). For each mode the user can
independently define from which control source a start or stop shall be possible. In addition it handles the device reaction in
the event of a bus fault.
If there are special requirements for the start/stop logic the function block can be left out. In this case all the
related parameters have no meaning anymore. This includes the bus fault function too!
