Example of Programming
to Process Data
Ladder Programming with Tag Data Links
Programming for Revision 1 or Higher
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.
