Instance
In this case, the input to EN is bit 0.0 at the left of the diagram.
•
When the input to EN is ON, the instance is executed and
the execution results are reflected in bit 1.0 and word D10.
•
When the input to EN is OFF, the instance is not executed,
bit 1.0 is turned OFF, and the content of D10 is not changed.
