Element Description
Rung Element - The basic executable unit in the new Ladder Editor. Each
rung has at least one input condition and one output condition. The True or
False value of an input determines the output value. You can add a
comment to a rung to clarify or describe the instruction.
Branch Element - Connection element that adds OR logic in the new Ladder
Editor. The branch element always resides on a rung element and,
therefore, cannot exist without the rung element.
Branch Level Element - Connection element that adds OR logic in the new
Ladder Editor. The branch level element can reside on a branch element or a
branch level element. The branch level element can also store instructions.
