CC-Link System Access Range for Monitoring

■1. When using Bus connection/CPU direct connection/serial communication connection
Only connected stations can be monitored.
■2. When using CC-Link connection (intelligent device station)
(1) Access range
The master station and local station can be monitored.
Monitor target
Master station (Remote network Ver.2 mode)
Local station Station No.1 (Ver.1 compatible)
Local station Station No.6 (Ver.2 compatible)
*1 Monitoring is available only when the CC-Link communication module is the GT15-J61BT13.
All devices RX, RY, RWw and RWr that are allocated to the master station by the CC-Link parameter setting can be
monitored.
When the monitor target is the multi-PLC system, CPU No. 1 to No. 4 can be monitored.
The device range of RX, RY, RWw, RWr to be allocated to the GOT differs according to the setting of the number of
CC-Link communication units (one station/four station) occupied.
For details on the number of CC-Link stations occupied, refer to the following manual .

(2) Setting device name and device number
(a) Monitoring devices RX, RY, RWw and RWr that are allocated to the master station by CC-Link
parameter setting
Use the following device names.
For devices RX, RY, RWw and RWr, designate the addresses allocated by station number setting.
