Special relays/LC devices capable of high-speed transfers with
the HCMOV/DHCMOV instruction
Shown below are the special relay/LC device that can read and write the latest value with the HCMOV/DHCMOV instruction
when the FX3 compatible high-speed counter function is valid. When special relays and special registers are specified for (s)

capable of high-speed transfers with the HCMOV/DHCMOV instruction other than those described in the list below.
