4.6.2 Communication in the LAN serial bridge mode.
The schematic diagram of the communication system in the serial bridge mode is presented in the figure
below.
Fig.15. The schematic diagram of the communication system in the serial bridge mode.
The topology of the network is based on an Ethernet switch (e.g. switch, router) which serves as a bridge
between two segments of the RS485 bus. Each bus is connected to the RS485-Ethernet interface, of which one is
the Client and the other is the Server. Each interface has a static IP address. Communication between the PC and
the final PSU requires the address of the PSU in the RS485 bus.
„Serial Bridge” profile settings – Client/Server.
To configure the interface, connect the switch/router to the computer as shown in the Fig. 3.
After logging in to the interface configuration page, select the “Serial Ports” option from the “Configuration”
group and select the „Serial Bridge” profile from the „Select Port Profile” window. Confirm by pressing the „Apply”
button. Configuration of the „Client” interface differs from the configuration of the „Server” interface and should be
performed separately.
Caution! If the interface has been configured before, the “Serial Port Configuration” window with current profile will
appear instead of “Select Port Profile” window. If so, click on the „
Port 1
” in the displayed window and then select
the „
Change profile…
” at the top of the next window. The „Select Port Profile” window will be displayed and it will
be possible to select the „Serial Bridge” profile
