Operation
When this block has a TRUE value in EN, it updates the values of internal fields with the input variables, performs the Ladder routine programmed by the user and updates the values of the outputs after completing routine.
When EN has FALSE value, outputs remain unchanged.
The ENO value forwards to the next Ladder block the EN value after the operation is completed.
