The Show Power Flow feature enables you to check the logic of a net you create.
You can see the Power Flow directions and, from these, how the net will work in the project.
Right-click on the left Ladder bar. The Compiler Results menu appears.

Select Show Power Flow.

The net lines change color according to the power flow direction.

Each color represents a different direction of power flow.
