Ladder diagram

16-4-3 Overview of PLC ladder diagram editing

The program editing method begins from the left busbar and proceeds to the right busbar (the

right busbar is omitted when editing using WPLSoft). Continue to the next row after completing each

row; there is a maximum of 11 contacts on each row. If this is not sufficient, a continuous line will be

generated to indicate the continued connection and more devices can be added. A continuous series

of numbers will be generated automatically and identical input points can be used repeatedly. See

figure below:

The ladder diagram programming method involves scanning from the upper left corner to the

lower right corner. The coils and applications command-computing box are handled in the output,

and the ladder diagram is placed on the farthest right. Taking the figure below as an example, we can

gradually analyze the procedural sequence of the ladder diagram. The number in the upper right

corner gives the sequential order.
