3 Function and System Design
3.1 Function
Fieldgate FXA520 is designed for two main applications, inventory control and remote maintenance
of HART transmitters
3.1.1 Inventory Control
Fieldgate FXA520 allows owners, vendors and suppliers to remotely acquire the current levels of
products in tanks or silos, e.g. in order to account for them in their own production planning.
Fieldgate allows level limits to be configured and, if required, automatically activates the next
delivery. The options here range from a simple purchasing requisition via e-mail through to fully
automatic order administration when XML data is coupled into the planning systems on both sides.
For more sophisticated applications, Hauser’s SupplyCare software for Inventory Control
can be used.

3.1.2
Remote maintenance
Fieldgate FXA520 not only transfers measured values, it also alerts standby personnel via e-mail or
SMS about device status. In the event of an alarm or when performing routine checks, service
technicians can remotely diagnose and configure connected HART devices using HART operating
software. Hauser’s FieldCare supports the user in remote configuration and maintenance,
whereby Fieldgate operates as a transparent gateway.
