Fieldgate FXA720

Ethernet gateway with integrated Web server
for communication with PROFIBUS devices

Application
Fieldgate FXA720 is an Ethernet/PROFIBUS DP gateway
with integrated Web server. It may be equipped with up
to three PROFIBUS DP ports.
Fieldgate FXA720 is suitable for several applications:• Inventory control• Remote monitoring and device diagnosis• Plant access point
For inventory control, remote monitoring and device
diagnosis, the connected devices can be viewed with aWeb browser: limit values can be set by the user. In passthrough mode, Fieldgate FXA720 acts as a simple
PROFIBUS DP gateway for host applications.

Features and Benefits• Quick set-up via Web browser– No configuration tool necessary• Communication via Internet– Worldwide access to sensor data
• User Management– Limits access to authorised persons• Integrated Web server– Values available to any Web browser• Alarming and event messaging– E-mail about device status• Data offered in HTML and XML format– Seamless data integration intoMS Office, P View and FieldCare• CommDTM supplied– Simple integration into FDT frameapplications, e.g. FieldCare• Monitoring via OPC– OPC server can be supplied.

Function and System Design
Function

Fieldgate FXA720 is a Ethernet/PROFIBUS gateway with integrated Web server that can be used as:• a pass-through interface within a PROFIBUS monitoring and control system• a plant access point for device diagnostics and maintenance• a remote data acquisition module for PROFIBUS devices connected to its output ports
It connects host systems to PROFIBUS DP networks via Ethernet and can be equipped with up to three
PROFIBUS DP channels, each giving access to up to 125 PROFIBUS DP devices.
Within a control system, Fieldgate ensures transparent vertical communication by acting as a simple passthrough gateway. A CommDTM allows it to be integrated into a FDT frame application such as FieldCare. For
Web applications, the unit contains a Web server that generates HTML pages for viewing in a standard internet
Web browser. It also offers XML data for e.g. Office applications. An optional PROFIBUS OPC server facilitates
data exchange with HMI/SCADA applications such as ControlCare P View or with PROFIBUS devices.

System design
Network applications

In this application, Fieldgate FXA720 provides the connection between host applications running on Ethernetand PROFIBUS devices connected to a PROFIBUS DP or PROFIBUS PA network.
Examples of applications running on Ethernet are:
• HMI/SCADA programs, e.g. ControlCare P View
• Asset Management tools, e.g. FieldCare• Configuration tools, e.g. FieldCare• Microsoft® Office and ERP applications

Web-based applications

In this application Fieldgate works together with a standard Web browser and related technologies. The devices
to be monitored or configured are connected to the Fieldgate FXA720 via max. three PROFIBUS DP channels,
to which PROFIBUS DP devices can be connected directly. PROFIBUS PA devices are connected to the DP
segment via a segment coupler.
The remote connection is made either by:• Ethernet port/Remote wireless LAN access points• Ethernet port/Internet
The following applications may be running on the monitoring station:• Microsoft® Office applications (on-line data acquisition and display)• Fieldgate Viewer (data acquisition and simple visualization)• ControlCare P View (SCADA application with trends and historian)• FieldCare (Asset Management, configuration) or other configuration tool
