7 High-speed Counters
W0.00
When execution condition W0.00 turns ON, the comparison starts for 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.
