3-20 High-speed Counter/Pulse Output Instructions
This section describes instructions used to control the high-speed counters
and pulse outputs.
3-20-1 MODE CONTROL: INI(880)
Purpose INI(880) can be used to execute the following operations for built-in I/O:
• To start comparison with the high-speed counter comparison table
• To stop comparison with the high-speed counter comparison table
• To change the PV of the high-speed counter.
• To change the PV of interrupt inputs in counter mode.
• To change the PV of the pulse output (origin fixed at 0).
• To stop pulse output.
