Connection 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.
■1. Serial communication connection
• 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.
➠
• 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.
➠
• 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.
➠
■2. Restrictions on connection to head module
The GOT does not allow the clock of the master station to be set in the clock setting of the utility function.
The master station clock will not change even if the clock setting is made.
Use GX Works or similar software to set the PLC CPU clock of the master station.
