Anybus Wireless Bridge - Ethernet to WLAN
Doc.Rev. 1.30
3.6 PC Connected Wirelessly to Wireless Bridge
- Alternative 1
3.6.1 Overview
In this use case only ONE Ethernet device is connected to the Wireless Bridge. The PC is used to access
the Ethernet device, using any Ethernet-based protocol, e.g. a built-in web interface or an Ethernet
based communication protocol e.g. Modbus-TCP.
3.6.2 Set Up the Use Case
The Wireless Bridge must operate in Client Mode in this use case.
1. Connect a PC to the Wireless Bridge. See section “Using the Web Configuration Interface” on
page 10 for more information on how to connect to the Wireless Bridge.
2. Define the WLAN connection parameters. The following parameters are required:
How the PC is set up is dependent on the Wireless LAN solution supported for the PC. Use the WLAN
GUI to search for an ad-hoc network with the same SSID as the one set for the module. Select WEP as
encryption, and select the same WEP key that you entered during the Wireless Bridge configuration.
