Element: Network

A network is the basic unit of an LD program. In the Ladder editor, the networks are arranged in a list below each other. Each network is provided with an incremented network number on the left side and can include the following: logical and arithmetic expressions, program/function/function block calls, jumps or return statements.

You can provide each network with a title, comment or jump label.

Network title: Double-click the first line at the top of a network to specify it.

Network comment: Double-click the second line at the top of a network to specify it.

Jump label: Double-click the third line at the top of a network to specify it. The jump label can then be specified as a target at the Jump element.

In the TwinCAT options, category Ladder you define whether network title, network comment and separator lines between the individual networks are displayed in the editor.
