(1) Points per module and per system
For the points, refer to the table of the performance specifications. (
In CC-Link, increasing the number of occupied stations can increase the number of points per module. The
number of occupied stations is set for each slave station. (
7.4.2 (1))

Number of Occupied Stations
(2) Data transfer between RX, RY, RWr, and RWw and a device in a CPU module
(a) Automatic transfer by parameter settings using a programming tool
Setting a refresh device using the network parameter can automatically transfer data between RX, RY, RWr,
and RWw in a master/local module and a device in a CPU module. (
Section 7.4.2)
(b) Transfer using a program
Using an intelligent function module device (Un\G) and FROM/TO instructions transfers data between the
buffer memory areas in a master/local module and a device in a CPU module. Use this function to use a
different refresh device for each station or for other purposes.

(3) Storage locations of RX, RY, RWr, and RWw
Areas are assigned by 32 points in the order of station number to the remote input (RX) and remote output (RY).
To the remote register (RWr and RWw), areas are assigned by four points in the order of station number.
( Page 331, Appendix 2 (2), Page 333, Appendix 2 (3))
The number of points is increased by increasing the station numbers
occupied per module.
Note that the number of slave stations that can be connected to a CC-
Link system is decreased because one module occupies the station
numbers for multiple modules.
