2
Set the range comparison table starting at word D2000. Even though range 1 is the only range
being used, all 3 0 words must still be dedicated to the range comparison table.
3
Create the program for interrupt task 12.
4
Use the CTBL instruction to start the comparison operation with high-speed counter 1 and inter-
rupt task 12.
When execution condition W0.00 turns ON, the comparison starts with high-speed counter 1.
When the PV of high speed counter 1 is between 25,000 and 25,500, cyclic task execution is
interrupted, and interrupt task 12 is executed.
When interrupt task 12 execution is completed, execution of the interrupted cyclic task resumes.
