Using RS-232 connection and Ethernet connection together

A GOT2000 series model and a Q06HCPU are connected by RS-232.
I want to connect a Q03UDVCPU to this GOT2000 series model by Ethernet.
How can I set it?
Category : 


The GT27, GT25, or GT21 model (Ethernet connection models) can monitor up to four controllers (four channels) (such as PLC CPU, temperature controller, and inverter) simultaneously by using the multi-channel function.
Since channel 1 of the GOT is used to connect the Q06HCPU, use channel 2 to connect the Q03UDVCPU by Ethernet.
The following describes an example of settings to connect the GOT and the Ethernet port built in the Q03UDVCPU by Ethernet.
* For the GT21 model (Ethernet connection model), up to two controllers (two channels) can be monitored simultaneously.
