Interrupt Functions Section 5-1
3. Create the program for interrupt task 12. Always put an END(001) instruc-
tion at the program’s last address.
4. Use CTBL(882) to start the comparison operation with high-speed counter
1 and interrupt task 12.
5. Operation
When execution condition W0.00 goes 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 processing is interrupted, and interrupt task 12 is processed. When
interrupt task 12 processing is completed, processing of the interrupted cy-
clic task resumes.
