3.7Connection to the Head Module of CC-Link IE Field Network System
When connected to the head module of the CC-Link IE Field Network, the GOT can monitor the PLC CPUs of the master station and local stations. When connecting the GOT to the head module, use the following connection methods.
Computer link connection
Monitor target | Network No. 1, Station No. 0 |
|
supply Power module | CPU CLP | T2-QJ71GF11 | Empty | Empty |
Network No. 1, Station No. 1
module | supply Power | T2-LJ72GF15 | LJ71C24 | LX40C6 | LY10R2 |
GOT
(1)Connect the GOT to the serial communication module (LJ71C24, LJ71C24-R2) mounted on the head module. For cables required for connection with the serial communication module and other details, refer to the following.

(2)Specify a GOT type which includes MELSEC-QnU in the controller type on GT Designer3. Then, specify [Network No. 1 (Network No. of CC-Link IE Field Network), Station No. 0 (Master station)] as the monitoring target in the network setting of the device setting dialog box. (GT16, GT15, GT14 only)
In this case, the GOT monitoring is performed by transient transmission of the CC-Link IE Field Network. Therefore, a longer time-lag occurs for displaying objects compared with directly monitoring the PLC CPU. For displaying objects with a shorter time-lag, execute the cyclic transmission so that the GOT can monitor link devices B and W of the host station set in the CC-Link field network.
For settings required for the PLC CPU, refer to the following manual.
MELSEC-L CC-Link IE Field Network Head Module User's Manual
(3)To monitor other networks, set the routing parameter to the PLC CPU as necessary. For routing parameter setting of the PLC CPU, refer to the following manual.
