The Ladder Diagram
36
The following diagram must be broken down into two blocks and each of
these then broken into two blocks before it can be coded. As shown below,
blocks a and b require an AND LD. Before AND LD can be used, however,
OR LD must be used to combine the top and bottom blocks on both sides,
i.e., to combine a1 and a2; b1 and b2.
This type of diagram can be coded easily if each block is worked with in or-
der first top to bottom and then left to right. In the following diagram, blocks a
and b would be combined with AND LD as shown above, and then block c
would be coded and a second AND LD would be used to combine it with the
execution condition from the first AND LD, and so on through to block n.
