The bottom output instruction is on a nested branch that is three levels deep. Large rungs with complex, nested branches result in having to scroll through. Ladder diagrams (sometimes called “ladder logic”) are a type of electrical notation and symbology frequently used to illustrate how electromechanical switches and relays are interconnected. The two vertical lines are called “rails”. In the example above, for the instructions to be true, either condition_1 or condition_3 must be activated together with condition_2. A branch is 2 or more instructions in parallel. There is no limit to the number of parallel branches but branches can only be nested up to 6 levels. Nested branch Optimisation.
