A network is the base unit of an LD program. The networks are processed sequentially from top to bottom and numbered consecutively on the left.

A network corresponds to a single instruction. It contains expressions, program calls, function calls, function block calls, or a jump or return instruction.

A network can optionally be given a title, a comment, and a jump label. The title, comment, and jump label are located in the first, second, and third lines at the top of the network. The jump label is used as a target for the Jump element.
