5-3-10 Example Pulse Output Applications
Outputting Pulses after a Preset Delay
This example program waits for a preset time (0.5 ms) after the interrupt input
(CIO 0.00) goes ON and then outputs 100,000 pulses at 100 kHz from pulse
output 0.
Input interrupt task 0 (interrupt task number 140) starts a scheduled interrupt
with a scheduled time of 0.5 ms. The scheduled interrupt task executes the
pulse output instructions and stops the scheduled interrupt.
Instructions Used MSKS(690) Enables the I/O interrupt. Starts the scheduled interrupt.
PULS(886) Sets the number of output pulses.
SPED(885) Starts the pulse output.
