CMP (pulse output control / output signal)
Position comparison function: when the motion control position matches the program's position
comparison setting, the PCI-M324 generates a pulse signal. PCI-M324 has built-in functions for
two high-elastic CMP comparators: Channels #0 and #1. Please refer to Section 3.1.4 for
hardware interface details.
