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.
Device allocation table
The devices used by the high-speed counter are as follows.
