Fieldgate FXA520
The Fieldgate FXA520 is a HART gateway with an integrated web server for the remote acquisition
of data from HART devices. These can be connected either directly via the HART multidrop
connector of Fieldgate FXN520 or via a HART multiplexer. The Fieldgate communicates with the
host computer via Ethernet. A connection between the FXA520 and the Field Xpert is established
by accessing an Ethernet WiFi access point.

Fieldgate Ports and IP addresses
During the configuration of the Fieldgate WiFi connection in the Field Xpert you will require the
following information:
• Fieldgate FXA520 IP address (default 192.168.252.1)
• Fieldgate FXA520 subnet mask (default = 255.255.255.0)
• Fieldgate Web Server Port Number (default = 80)
• Fieldgate Pass-through HART Port Number (default = 3222)
It is normal that the IP address and subnet mask are changed to addresses assigned by your system
administrator when Fieldgate FXA520 is installed in a control network. The access ports may also
differ. Provided you know the IP address of the Fieldgate, however, you can use a Web browser to
