Fieldgate FXA520 - Getting Started
1 Switch on the PDA, and activate WiFi communication in the iPAQ Wireless menu.
Establish a connection to your wireless network by selecting the relevant network and
configuration in the WiFi Settings and Manager.
2 Once you are connected to the network, (green WiFi icon), open the “Device Xpert”
configuration software and add your Fieldgate FXA520 connection to it under “View,
Configuration, Add connection”.
3 Select “Device”, “Scan” in the main menu. Then select the configured connection and start the
scan. It is now possible to configure and diagnose the connected HART devices quickly and
easily.

Fieldgate FXA520 - Detailed information
5.3.1
Connecting the Fieldgate
Field Xpert communicates with a HART device via the Fieldgate FXA520. The connection between
the Field Xpert and the FXA520 is wireless via WiFi.
Regarding the connection between the FXA520 and HART device, there are three options available:
HART point-to-point, HART multiplexer and HART multidrop.
HART point-to-point
connection
Two HART devices can be connected directly to the input channels of the Fieldgate FXA520.
If the appropriate version of Fieldgate was ordered, the devices can be used in hazardous areas. The
inputs meet the requirements of SIL 2 for
4 to 20 mA loops (IEC 61508). The devices can be configured both onsite and remotely.
HART multiplexer
The RS 485 interface for Fieldgate FXA520 can be used for connecting up to two HART
multiplexers, e.g. the KFD2-HMM-16 from Fuchs. Up to 30 HART devices can be
connected in this way.
If the devices are used in a safe area, the RNS221 transmitter power supply can be used to power
two devices.
Ex devices can also be installed in hazardous areas. In this case, the signal must be connected to the
safe side of a RN221N-B transmitter power supply.
HART multidrop
With the FXN520 multidrop module, up to 2x eight HART devices operating in a non-hazardous
area, can be connected to the Fieldgate.
Detailed information on connecting the FXA520 can be found in the Operating Instructions for the
FXA520.
