Built-in Outputs Section 7-1
7-1-2 Outputting Pulses after a Preset Delay
Specifications and Operation
This example program waits for a preset time (0.5 ms) after the interrupt input
(2960.03) goes ON and then outputs 100,000 pulses at 100 kHz from pulse
output 0.
The I/O interrupt task starts a scheduled interrupt with a scheduled time of
0.5 ms. The scheduled interrupt task executes the pulse output instruction
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.
