Fieldgate SFG500
Smart Ethernet/PROFIBUS gateway

Parallel access to PROFIBUS networks
Monitoring of PROFIBUS and HART device status
Application
Fieldgate SFG500 is a system component that provides independent access to a
PROFIBUS network. It can be used in a variety of applications that are supported byspecific operating modes. The suitable operating mode is determined by an optional
memory card (Fieldgate module SFM500). Without a memory card, Fieldgate
SFG500 acts as a plant access point. In this case, it functions as an Ethernet gateway
with adaptive PROFIBUS Master Class 2 capabilities and supports FDT-based plant
asset management applications, such as FieldCare for example. When a memory cardis used, device diagnostics information such as the NAMUR NE107 status, with thereason for failure and remedial measures, as well as process values from PROFIBUS
and HART devices are displayed in the integrated Web browser.
Your benefits• PROFIBUS listener and Master Class 2: integrates automatically into a PROFIBUS
network and finds all PROFIBUS devices• HART support via PROFIBUS: HART device support and device diagnostics• PROFIBUS observer: monitors network traffic and process values with devicediagnostics• Web server: provides a clear overview of the network and diagnostic information
via the Web browser or FDT/DTM frame application• SFGNetwork DTM: finds all the Fieldgate SFG500 devices in an Ethernet domain
and displays their PROFIBUS connections• Fieldgate module SFM500: enables the functions for displaying process values anddiagnostics information

Function and system design
Function

Access point
The simplest application is to use the Fieldgate SFG500 as an access point together with FieldCare,Endress+Hauser's plant asset management system. In this scenario, FieldCare accesses all the devices
in the PROFIBUS DP segment via the SFGNetwork DTM. Apart from setting the IP address, and thePROFIBUS bus parameters in some cases, no additional configuration is required.
Fieldgate module SFM500
Fieldgate SFG500 can be used for other applications with the Fieldgate module SFM500.

System design

The control network comprises, for example, a PLC or DCS system and one or more PROFIBUS DPsegments. Depending on the actual scenario, it is possible that additional Class 1 Masters areconnected to the network. In addition, PROFIBUS DP slaves, remote I/Os and segment couplers or PAlinks are also connected to the PROFIBUS DP segment. With remote I/Os, for example, it is possible
to integrate HART devices into the PROFIBUS DP network. Segment couplers or PA links establish aconnection to PROFIBUS PA slaves and also provide them with power.
Via its Ethernet port, Fieldgate SFG500 allows host applications to access data from the PROFIBUS
DP segment independently of the control system. The local area network (LAN) in which the hostapplications operate can be a separate network or an integral part of the control network. Fieldgate
SFG500 only connects to one PROFIBUS DP segment. If there is more than one segment in aPROFIBUS DP network, a separate SFG500 module is required for every segment.
Fieldgate SFG500 can be configured from any computer in the LAN via a Web browser (e.g. InternetExplorer). LAN2 has a DHCP server which assigns an address to a connected computer.

We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertentchanges to the device settings.
IT security measures in line with operators' security standards and designed to provide additional
protection for the device and device data transfer must be implemented by the operators themselves.

InstallationLocation• Fieldgate SFG500 has been designed for use at a permanent and weather-protected
location in a non-Ex area
• The installation environment should be a metal cabinet or an installation framewith a well-grounded mounting plate

Installation instructions • Vertical installation on a top-hat rail, the rail clip can be fitted at two height
positions• Fieldgate SFG500 requires lateral clearance from other modules and can therefore
not be mounted directly beside every other non-Ex module• To ensure adequate ventilation and prevent overheating, the vertical and lateralclearance between the modules and the cabinet duct or cabinet wall must be atleast 50 mm
