■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 and extended cyclic settings can increase points per module. Set the
number of occupied stations and extended cyclic settings for each slave station.
Item Description
Number of Occupied The number of points is increased by increasing the station numbers occupied per module.
Stations 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.
Extended Cyclic The station numbers occupied by one module are not changed, and only the number of points are increased.
Setting Unlike "Number of Occupied Stations", the number of slave stations connected to a CC-Link system is not decreased. Note, however,
that the transmission delay time is extended compared to that of when the number of points is increased in "Number of Occupied
Stations".
■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.

■Storage locations of RX, RY, RWr, and RWw
The storage locations change depending on the number of occupied stations and extended cyclic settings in slave stations.
The storage locations for each station can be checked using Slave station offset, size information (Un\G992 to Un\G1503).
( Page 146 Slave station offset, size information)
• Data stored in RX, RY, RWr, and RWw in the local station side are stored in a remote net Ver.1 mode area
when the master station is in the remote net Ver.2 mode and the local station is in the remote net Ver.1
mode. Four points are occupied per station for RWr and RWw in a remote I/O station. ( Page 19 Data
transfer between RX, RY, RWr, and RWw and a device in a CPU module)
• When the mode is changed from the remote net Ver.1 mode, in the remote net Ver.2 mode, RWr and RWw
in a remote I/O station move over and assigned with 0 points. The assignment of the station numbers for
stations after the remote I/O station changes; therefore, change the program if required.
