Ethernet connection

(1)Connect the GOT to the Ethernet module (QJ71E71-100, QJ71E71-B5, QJ71E71-B2, QJ71E71) mounted on the remote I/O station.

For details of cables and others required for connecting the GOT to the Ethernet module, refer to the following.

8. ETHERNET CONNECTION

(2)Specify a type including MELSEC-Q (including multiple), or MELSEC-QnU for the controller type on GT Designer3. Then, specify [[NW No.] (Network No. of the remote I/O network) to 1, and specify [Station No.] (Master station) to 0.] as the monitoring target in the network setting of the device setting dialog box. (GT16, GT15 only)

The GOT monitors stations on the MELSECNET/H network with the transient transmission.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 remote I/O station.

For settings required for the PLC CPU, refer to the following manual.

Q Corresponding MELSECNET/H Network System Reference Manual (Remote I/Q network)

(3)To monitor other networks, set the routing parameter to the GOT and PLC CPU as necessary. For routing parameter settings of the GOT, refer to the following manual.

8. ETHERNET CONNECTION

For routing parameter settings of the PLC CPU, refer to the following manual.

Q corresponding MELSECNET/H Network System Reference Manual (PLC to PLC network)

Restrictions on connection to remote I/O station

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 Developer or a similar software to set the PLC CPU clock of the master station.
