3.1
Function
Field Xpert from Hauser is a high-performance industrial PDA based on Windows Mobile,
with compact external dimensions, an integrated WLAN, USB, Bluetooth and infrared connection.
This allows it to be connected to HART and/or FOUNDATION fieldbus devices via a modem or
gateway. With a range of Ex approvals, Field Xpert meets the needs and requirements of the process
industry for applications inside and outside hazardous areas.
Once the Field Xpert hardware and the Device Expert software are communicating with a device,
it can be parameterized. Depending upon the system architecture, only one device may be seen, e.g.
in HART point-to-point or all the devices connected to the segment, e.g. in FOUNDATION fieldbus
applications.
