Product description

Fieldgate SFG500 is a system component that provides an independent access route to a PROFIBUS network.

Your benefits

PROFIBUS listener and Master Class 2: automatically integrates itself into a PROFIBUS network and finds all connected devices
PROFIBUS observer: monitors network traffic and device diagnostics
Web Server: provides a clear presentation of network and diagnosis information via Web Browser or FDT/DTM frame application
SFGNetwork DTM: finds all SFG500 Fieldgates present in an Ethernet domain and displays their PROFIBUS connections
Fieldgate Module SFM500: activates additional operating modes as well as the associated outputs (Modbus RS-485 interface and relay output)

Field of application

Fieldgate SFG500 may be used in a variety of applications that are supported by specific operating modes. The operating modes are determined by the use of an optional memory card (Fieldgate Module SFM500). Without a memory card, Fieldgate SFG500 operates as a plant access point. In this case, it acts as an Ethernet gateway with adaptive PROFIBUS Master Class 2 capabilities to support FDT-based plant asset management host applications, e.g. FieldCare. Applications which require a memory card are in preparation.

Function and system design

Function

Access Point: When no Fieldgate Module SFM500 is inserted in the Fieldgate SFG500, it acts as a Access Point. Here it is used together with FieldCare, Endress+Hauser's plant asset management system. FieldCare accesses all devices in the PROFIBUS DP segment through the Fieldgate SFGNetwork DTM. Apart from setting the IP address, and in certain circumstances the bus parameters, no configuration is necessary.
Fieldgate Module SFM500: With the appropriate Fieldgate Module SFM500 inserted, Fieldgate SFG500 can be used for other applications. The SFM500 activates the corresponding operating mode and enables the associated outputs (Modbus RS485 interface, relay output).

System design

The figure below shows the integration of Fieldgate SFG500 operating as an Access Point in a PROFIBUS network. Click on it for an enlarged view.

The control network comprises for example, a PLC or DCS system and one or more PROFIBUS DP segments. Depending upon the actual circumstances it is possible that additional Class 1 masters are connected to the network. Also connected to the PROFIBUS DP segment are PROFIBUS DP slaves, Remote I/Os and segment couplers or links. Remote I/Os allow e.g. HART devices to be integrated into the PROFIBUS DP network. Segment couplers or links provide a connection to PROFIBUS PA slaves and also supply them with power.

Through its Ethernet port (LAN1), Fieldgate SFG500 allows host applications to access data from the PROFIBUS DP segment independent of the control system. The local area network in which they operate may be separate from the control network or be an integral part of it. Fieldgate SFG500 connects to a single PROFIBUS DP segment only. If there is more than one segment in the PROFIBUS DP network, a separate Fieldgate SFG500 is required for each.

Fieldgate SFG500 can be configured by a web browser, e.g. Internet Explorer, from any computer in the local area network or via its second Ethernet port (LAN2). In the latter case, Fieldgate SFG500's DHCP server will supply an IP address to the connected computer.
