(3) Setting NW No. and station number
(a) When monitoring devices RX, RY, RWw and RWr that are allocated to the master station by CC-Link
parameter setting
NW No.: 0, PLC station number: Local
(b) When monitoring PLC CPU devices of another station
NW No. 0, PLC station number: Other (Station number: n)
(n: Station number of another station to be monitored (0: Master station, 1-64: Local station))
■3. When using CC-Link connection (via G4) (Q series only)
(1) Access range
GT27 can monitor the master station and local stations.
(2) Setting NW No. and station number
(a) When monitoring master station
NW No.: 0, PLC station number: Host/other (station number: 0)
(b) When monitoring local station
NW No.: 0, PLC station number: Other (station number: 1 to 64)
(3) Setting device name and device number
Set the device name and device No.

3.3 CC-Link System Access Range for Monitoring
POINT POINT POINT
For monitoring devices RX, RY, RWw and RWr that are allocated by CC-Link parameter, use the
local device even if designating devices allocated to another station.
Otherwise, the display speed will be reduced.
2.DEVICE RANGE THAT CAN BE SET
Monitoring by transient transmission
Devices of the PLC CPU on the CC-Link system master and
local station are specified and monitored.
The CC-Link parameter setting sequence program is
required. However, the GOT communication sequence
*1
program is not needed.
The data communication processing speed is lower than that
of cyclic transmission.
This program is not required if the CC-Link parameter setting sequence program and GOT communication sequence program
satisfy the following conditions.
• Use a QCPU (Q mode) or QnACPU whose number given in the DATE field of the rating plate is "9707B" or later as the PLC
CPU of the master station.
• Use GX Developer or SW2 -GPPW and make CC-Link parameter setting and batch refresh device setting in the CC-Link
setting on the package.
For details of the connection method, refer to the following manual .
➠
User's manual of the CC-Link master unit to be connected
For whether the data can be sent to/received from the CC-Link Ver. 2 compatible station by transient transmission and cyclic
transmission, refer to the following.
➠ ■2.
When using CC-Link connection (intelligent device station)
POINT POINT POINT
In transient transmission, connection of several (five or more as a guideline) intelligent device
stations (GOTs and intelligent device units) reduces the data communication speed.
To raise the data communication speed, increase the CC-Link system, for example, and do not
connect five or more intelligent device stations to a single CC-Link system.
*2
Monitoring by cyclic transmission
All remote inputs/outputs and remote registers assigned to
the Master station by CC-Link parameter setting are specified
and monitored.
The data communication processing speed is high.
• Writing from the GOT (read command from the
master station) can be performed only to remote
outputs and remote registers assigned to the GOT
of the master station and to the GOT internal
registers.
• GOT communication sequence program is
*1
required.
