XD, XL series PLC has HSC (High Speed Counter) function which will not affect by the
scanning cycle. Via choosing different counter, test the high speed input signals with detect
sensors and rotary encoders. The highest testing frequency can reach 80 KHz.
Note:
(1) The high-speed counting input of XD/XL series PLC can only receive collector open-
circuit signal (OC), but can not receive differential signal, so it is necessary to select the
encoder of collector open-circuit signal (OC).
(2) When the counting frequency is higher than 25Hz, please select a high-speed counter.
(3) The XD1/XL1 series does not support high-speed counting.
