Insert FBD objects on a line

The FBD"Function block diagram" A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks editor enables you to insert an object on an existing line and automatically connect it to the line. This feature is available for all objects having one input pin and one output pin, such as variable boxes, contacts and coils. This feature is mainly useful when entering elements of Ladder Diagrams. Just draw a horizontal line between left and right power rails: it is the rung. Then you can simply insert contacts and coils on the line to build the FFLD rung.
