High-speed counter devices
The high-speed counter operates according to special internal relay and special data register settings. While the high-speed
counter is operating, the current value, control output, and operating status value are reflected in the special internal relays and
special data registers with each scan.
The high-speed counter start and stop control signals and the current value, preset values, and reset values are allocated to the
special internal relays and special data registers.
