New Emerson Interface Connects Monitoring Applications of FOUNDATION(TM) Fieldbus Devices to Legacy Hosts

April 082003
Advanced field devices and diagnostics are useable even where fieldbus I/O
is unavailable


CHANHASSEN, MN (April 7, 2003) - Emerson Process Management introduces its new Rosemount(R) Model 3420 fieldbus interface module (FIM). This innovative product provides an interface between FOUNDATION(TM) fieldbus devices and any host system with Modbus(R) capability. Additional host protocols such as OPC, Modbus TCP/IP, and others will become available in future releases. The initial FIM release supports temperature and pressure monitoring applications using Emerson fieldbus devices.

This product allows users in facilities with existing hosts without fieldbus I/O to obtain the benefits of fieldbus networking and the enhanced capabilities of FOUNDATION fieldbus products, including multi-sensor devices and diagnostics information. The FIM delivers immediate efficiencies to legacy systems, while providing a stepping stone to the full benefits of PlantWeb(R) digital plant architecture.

The Model 3420 interfaces with up to four FOUNDATION fieldbus H1 segments, with the potential to connect up to 64 Fieldbus devices. In temperature applications using the Rosemount Model 848T eight input temperature transmitter, up to 416 temperature points can be monitored using a single FIM. Installation savings of 30% or more can be realized while providing a more robust and accurate temperature measurement than is possible in more traditional installations. The Model 3420 is powered by 24VDC and provides power to each of the devices on the fieldbus segments. Optional power conditioners integral to the NEMA 4X /IP65 enclosure provide a simple package that can be installed in any indoor or outdoor general purpose area including certification for FM & CSA Class 1, Division 2 and CENELEC Type n.

Configuration of the fieldbus devices and setup of the Model 3420 is accomplished using an embedded web server in the FIM and a standard internet browser on a PC. The ethernet connection can be made part of a plant's intranet network for remote access to the measurement data and diagnostic
information.
