4.6 STEP 4 – Selecting the communication mode.
Communication with the RS485-WiFi interface is possible in various modes. The selection is made by
choosing the appropriate profile in the web browser of the interface and configuring appropriate parameters. The
profile selection must be made on the basis of LAN connection between interfaces and power supply units taking
part in the communication.
4.6.1 Communication in WLAN/WAN network.
- Communication in WLAN network:
Shown below is a block diagram of communication in WLAN.
Fig.14. A block diagram of WLAN communication system.
The topology of the network is based on wireless Wi-Fi router connected to another PSU segments
(connected in the RS485 bus) via the RS485-WiFi interface. Each interface has a static IP address.
Communication between a PC and the final PSU is by giving the IP address of the interface, the address of the
PSU in the RS485 network and the number of the port responsible for the communication.
If the foregoing topology has been chosen, proceed to chapter 'TCP Sockets profile settings' to make the
configuration of the interfaces.
