Ladder logic follows a left to right principle. In the example below, the current flows through paths
started from either X0 or X3.
Reverse Current
When a current flows from right to left, which makes a reverse current logic, an error will be detected when compiling the program. The example below shows the reverse current flow.Reverse Current When a current flows from right to left, which makes a reverse current logic, an error will be detected when compiling the program.
