The status of a rung instruction (true or false) depends on the logic state of the data file bit
this instruction is shown in Figure 6, for example, indicates the status of the instructions
Examine If Closed (XIC) and Examine If Open (XIO), according to the logic state of the
corresponding data file bit. From this figure, we can see that:
• The Examine If Closed (XIC) instruction is true when its associated bit is at logic state 1;
• Conversely, the Examine If Open (XIO) instruction is true when its associated bit is at logic
state  
Series (AND) and Parallel (OR) Logics
The ladder rung in Figure 2 is an example of series (AND) logic. Series logic means that all
the instructions in the rung (XIC I: 0/0 AND XIO I: 0/1) must be true in order for output
instruction OTE O: 0/1 to be true.
The ladder rung in Figure 7 is an example of parallel (OR) logic. Parallel logic means that
one or another path of true instructions must exist on the rung in order for the output
instruction to be true. In Figure 7, at least one of the input instructions XIC I:0/1 OR XIC
I:0/2 must be true in order for instruction OTE O:0/1 to be true. Parallel logic is programmed
by branching instructions in a ladder rung.

 Documenting a Ladder Program
You can document a ladder program by inserting rung comments, instruction descriptions,
and address descriptions. This allows you to keep notes on:
• How your ladder program works;
• The purpose of an instruction or a rung;
• The type of input or output device (pilot lamp, pushbutton, limit switch, etc.) associated
with each address;
• The conditions required for a rung to be true.
You can insert your comments and descriptions while you enter a ladder program or after you
have entered it. The three types of comments and descriptions which can be inserted are
described below.
