2. Interrupt pointers
1) Input interrupt pointers
The PLC can receive input signals from specific input numbers without affected by its operation cycle. By
using these input signals as triggers, the PLC executes interrupt routine programs.
Because input interrupt pointers can handle signals shorter than the operation cycle, use them for high-
priority processing during sequence control or for control handling short pulses.
