Ladder Diagram Workspace

The ladder diagram workspace is the area of the screen where objects and links are placed to create the ladder diagram program. Most objects can be placed at any location in the workspace provided there is actual space available. The DIRECT coil, INVERTED coil, LATCH coil and UNLATCH coil are the only objects that must be placed in a particular location. They must be located next to the right power rail. Any attempt to place one of them in another location will cause an error dialog box to be displayed.

A ladder diagram is created using “rungs”. A rung is a horizontal line of logic. EZ LADDER® allows the maximum number of rungs to be configured when the target is selected in the Project menu.

Rungs may be inserted and deleted from the ladder diagram workspace. This will be discussed later.
