The basic concept of address assignment (memory map) for the CC-Link master PLC has been explained in
5.2. This section explains a case when the gateway unit is a remote station. If the gateway unit is a remote
device station (remote station which handles bit information and word information), the number of exclusive
stations depends on the operation mode.
