Basic Ladder Diagrams

A ladder diagram consists of two vertical lines running down the sides with lines
branching in between them. The vertical lines are called bus bars; the branch-
ing lines, instruction lines or rungs. Along the instruction lines are placed
conditions that lead to other instructions next to the right bus bar. The logical
combinations of the conditions on the instruction lines determine when and how
the instructions at the right are executed. A ladder diagram is shown below.

As shown in the diagram above, instruction lines can branch apart and they can
join back together. The short vertical pairs of lines are called conditions. Condi-
tions without diagonal lines through them are called normally open conditions
and correspond to a LOAD, AND, or OR instruction. The conditions with diago-
nal lines through them are called normally closed conditions and correspond
to a LOAD NOT, AND NOT, or OR NOT instruction. The number above each
condition indicates the operand bit for the instruction. It is the status of the bit
associated with each condition that determines the execution condition for fol-
lowing instructions. Only these conditions and a limited number of intermediate
instructions can appear along the instruction lines. All other instructions must
appear next to the right bus bar. Instructions that appear next to the right bus bar
are called right-hand instructions.

The way the operation of each of the instructions corresponds to a condition is
described below. Before we consider these, however, there are some basic
terms that must be explained.

4-3-1 Basic Terms

Each condition in a ladder diagram is either ON or OFF depending on the status
of the operand bit that has been assigned to it. A normally open condition is ON if
the operand bit is ON; OFF if the operand bit is OFF. A normally closed condition
is ON if the operand bit is OFF; OFF if the operand bit is ON. Generally speaking,
you use a normally open condition when you want something to happen when a
bit is ON, and a normally closed condition when you want something to happen
when a bit is OFF.
