// Run Forward
If ((RunForwardIn = True) and (RunReverseIn = False)) then ControlWord := 16#047C; End_If;

// Run Reverse
If ((RunForwardIn = False) and (RunReverseIn = True)) Then ControlWord := 16#847C;  End_If;

// STOP
If ((RunForwardIn = FALSE) (*And (RunReverseIn = False)*) And (ResetIn = False)) then ControlWord := 16#043C; End_If;

// RESET
If ((RunForwardIn = FALSE) (*And (RunReverseIn = False)*) And (ResetIn = True)) then ControlWord := 16#04BC; End_If;
