Modbus TCP/FF HSE to FOUNDATION Fieldbus H1 Gateway

Integration of up to 4 FF H1 segments into control systems via Modbus TCP or FOUNDATION Fieldbus HSE

With Softing’s FG-200, it is possible to integrate up to four FOUNDATION™ Fieldbus (FF) H1 links into control systems supporting Modbus. The FG-200 provides redundancy and is suitable for use in hazardous areas. This device features fast access to process data, while making use of FF advantages like reduced cabling, central field device parameterization, comprehensive diagnostics, or intrinsically safe device segments. It is compatible with the R. STAHL bus-Carrier Series 9419 and Fieldbus Power Supply Series 9412 products for easy commissioning.

The FG-200 is the successor product of FG-110. End of Life Announcement FG-110.

Easy Commissioning

  • Optional support of R. STAHL bus-Carrier Series 9419 and Fieldbus Power Supply 9412 products (cabling reduced to a minimum)
  • Modbus data import to web server reducing mapping efforts

Asset Management

  • Visitor mode avoiding interference with network behavior
  • Enabling asset management systems (e.g. Emerson’s AMS) and Field Device Tool (FDT) frame applications (e.g. SMART VISION, FieldMate, Field Device Manager, FieldCare, or PACTware)

Device Redundancy

  • Redundancy link enabling device redundancy (D-3 according to FF-593)
  • Automatic mirroring of configuration data
  • Very fast redundancy switch-over

All Necessary Tools Included

  • FF Configuration Tool for configuration of devices and cyclic communication
  • PACTware for device configuration and basic asset management tasks

EngineeringExisting projects can be downloaded without any changes
Mechanical DimensionsSmaller in each dimension: Same cabinet can be used
Bus Power Supply10 mA required per Link (same as for all devices and most host systems)
FISCO Power Supplies with separate host interface must provide 10 mA on host side
CablingDifferent positions, different connectors: Cables have to be modified
Redundancy Management

FG-100/FG-110 and FG-200 cannot cooperate as redundant pair:

No replacement of FG-110 by FG-200 in run possibe. Complete redundant pair of Linking Devices has to be replaced at same time.


Modify MTL 9107 FISCO Power Supply for FG-200

For the conversion of MTL 9107-22 redundant power supply to MTL 0109-22 the following components are required:

  • Module carrier 9109-CA-PS (Module Carrier 9107-CA-PS is replaced)
  • Host power supply module 9226-PU
