Ladder Programming with Tag Data Links
Section 6-3
Programming for Revision 1 or Higher
Example of Programming
to Process Data
The following type of programming can be used to process data only when the
data links are operating normally.
Interlocks (IL and ILC instructions) and jumps (JMP and JME instructions) can
also be used to process data only when the data links are operating normally
as shown below.

The parts of the ladder program
that use the data link area for
the relevant node are processed
only when the corresponding
Normal Operation Flag is ON.
