5.1 Special I/O Function Overview

The V200 PLCs support the special I/O functions as listed below:

	Quadrature	Counts the 2-phase pulses whose phases are shifted
	bi-pulse counter	90° each other. Counts up when phase A precedes,
		and counts down when phase B precedes. The
		countable pulse rate is up to 5 kHz.

Interrupt input function		Immediately activates the corresponding I/O interrupt
		program when the interrupt input is changed from OFF
		to ON (or ON to OFF). 2 points of interrupt input are
		available.
