3.6 Connection to Remote I/O Station in MELSECNET/H Network System
■1.
Direct CPU connection
• The network units (QJ72LP25-25, QJ72LP25G, QP72BR15) of the remote I/O station are handled as PLC CPU.
Connect the GOT to the RS-232 interface of the network unit.
For cables required for connection with the network module and other details, refer to the following.
➠
• 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 host station set in the MELSECNET/H network.
For settings required for the PLC CPU, refer to the following manual.
➠
Q Corresponding MELSECNET/H Network System Reference Manual (Remote I/Q network)
• To monitor other networks, set the routing parameter to the PLC CPU as necessary. For routing parameter settings of
the PLC CPU, refer to the following manual.

■2.
Serial communication connection
• Connect the GOT to the serial communication module (QJ71C24, QJ71C24-R2, QJ71C24N, QJ71C24N-R2,
QJ71C24N-R4) or modem interface module (QJ71CMO) mounted on the remote I/O station.
For the cables required for connection with the serial communication module or modem interface module and other
details, refer to the following.
