5-1 Functions Summary
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 80KHz.
Note:
(1) For PLC with NPN input mode, please choose the encoder with NPN open collector output
(OC) of DC24V; for PLC with PNP input mode, please choose the encoder with PNP open
collector output (OC) of DC24V.
