3 Function and System Design
3.1 Function
Fieldgate FXA320 is designed for inventory control applications. It possess two 4...20 mA input
circuits which can be switched to be passive (connected device has own power supply) or active
(Fieldgate powers the connected device). An additional four binary inputs for switches or counter
applications are available as an option.
3.1.1 Inventory Control
Fieldgate FXA320 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. The
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.
