3.3 CC-Link System Access Range for Monitoring

When using Bus connection/CPU direct connection/computer link connection

Only connected stations can be monitored.

When using CC-Link connection (intelligent device station)

(1)Access range

The master station and local station can be monitored.

			: Can be monitored, : Cannot be monitored
	Monitor target	Monitoring by cyclic transmission	Monitoring by transient transmission
Master station (Remote network Ver.2 mode)
Local station Station No.1 (Ver.1 compatible)
Local station Station No.6 (Ver.2 compatible)		*1
*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 . User's manual of the CC-Link master unit to be connected

(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.

•In the case of CC-Link Ver.2 (Device names to be refreshed automatically are indicated as X, Y, and D.)

Device name on PLC CPU		Automatic	Device name on master		Link	GT Designer3 settings
		refresh	station		scan	Device name	Set device range
Input	X	←	Remote input	RX	←	X	X0 to X1FFF
Output	Y	→	Remote output	RY	→	Y	Y0 to Y1FFF
Register (write area)	D	←	Remote register	RWw	←	Ww	Ww0 to Ww7FF
			(write area)
Register (read area)	D	→	Remote register	RWr	→	Wr	Wr0 to Wr7FF
			(read area)

• In the case of CC-Link Ver.1 (Device names to be refreshed automatically are indicated as X, Y, and D.)

Device name on PLC CPU		Automatic	Device name on master		Link	GT Designer3 settings
		refresh	station		scan	Device name	Set device range
Input	X	←	Remote input	RX	←	X	X0 to X7FF
Output	Y	→	Remote output	RY	→	Y	Y0 to Y7FF
Register (write area)	D	←	Remote register	RWw	←	Ww	Ww0 to WwFF
			(write area)
Register (read area)	D	→	Remote register	RWr	→	Wr	Wr0 to WrFF
			(read area)
