8.3. Master PLC address assignment
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.

* Number of links per one CC-Link remote station is 32 points (two words) for remote input and output, and
four points (four words) respectively for remote register, then a maximum 64 stations per one system can be
linked.
Number of links per one station can be expanded by the expanded cyclic setting.
