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?

Answer

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.

1. Configure the following settings in GT Designer3 (GOT2000).
