17: HIGH-SPEED COUNTER INSTRUCTIONS
17-8 USER’S MANUAL
Example: HSC2
The PULS (pulse output) instruction is used to generate output pulses. The output pulses are sent from output Q0 to input
I0. The HSC2 instruction is used to count the pulse signals up to 1000. When the preset value is reached, HSC2 stops the
pulse output at Q0 and turns output Q1 on.

I0: Pulse input
I1: Hard reset input (HSC2 is reset when I1 is off because the hard reset is set to LOW.)
I2: Input to execute the PULS (pulse output) instruction and to turn on soft reset special
internal relay M315
M301: Initialize pulse special internal relay
While input I2 is on, the PULS instruction generates output pulses at output Q0.
While hard reset input I1 is on, HSC2 counts input pulses to input I0. When the HSC2 cur-
rent value reaches 1000, the pulse output at Q0 is stopped, and output Q1 is turned on.
When hard reset input I1 is turned off or soft reset input I2 is turned on, HSC2 is reset.
When input I2 is turned off, the PULS instruction turns off the pulse output at Q0.
For monitoring high-speed counter preset and current values, see page 3-15.
