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.
