Each net must contain only one rung.
A Ladder net is the smallest division of a ladder diagram.
The Ladder diagram contains a left and right rail. Between these rails, the control application is arranged in nets. A net contains a row of Ladder elements that drive a coil.

Each net must contain only one rung.
|
Power flows through the ladder elements in a net from left to right.
This is why the first ladder element in the net must touch the left Ladder rail. All of the elements in a net must touch each other to allow power to flow through the net. You do not need to connect the last element on the right to the right side of the ladder in each net.

If the elements in a net are not connected, the software displays an error message at compilation. |
