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 PROJECTS and SETTINGS menu. Figure 2.3
shows the ladder diagram workspace and rungs of horizontal logic.
