5-3. High speed counting input
XG series PLC has a high-speed counting function independent of the scanning cycle of the programmable
controller. By selecting different counters, the measurement of high-speed input signals such as measurement
sensors and rotary encoders can be achieved. The maximum measurement frequency of XG1 can reach 80kHz,
and the maximum measurement frequency of XG2 can reach 200kHz.
Note:
(1)
The high-speed counting input of XG1 series PLC can only receive the open collector signal (OC), not the
differential signal. Please be sure to choose the encoder of the open collector signal (OC).
