■Points per module and per system
For the points, refer to the table of the performance specifications in the following manual.
 MELSEC iQ-R CC-Link System Master/Local Module User's Manual (Startup)
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.
Item Description
Number of The number of points is increased by increasing the station numbers occupied per module.
Occupied Note that the number of slave stations that can be connected to a CC-Link system is decreased because one module occupies the station
Stations numbers for multiple modules.
■Data transfer between RX, RY, RWr, and RWw and a device in a CPU module
To perform auto transfer using the module parameters in an engineering tool, setting a refresh device in "Link Refresh
Settings" under "Basic Settings" can automatically transfer data between RX, RY, RWr, and RWw in a master/local module
and a device in a CPU module.
To perform transfer using a program, use a module access device (Un\G) and FROM/TO instructions to transfer data
between the buffer memory areas in a master/local module and a device in a CPU module.
