For CC-Link and CC-Link IE Field, the assignment should be made in the order of RY, RWw, RX
and RWr.
<Caution>
As RXN is a system domain in CC-Link, turning on the applicable OM would not be reflected to
the host PLC. When the communication with the host PLC is conducted in normal condition, the
values at the RXN memory assignment on the host PLC side should be on in Bit 11 (0x0B) and
off in other bits. This Bit 11 is a remote READY flag for connection status confirmation.
