ProSoft Technology Introduces the Honeywell DE Smart Transmitter Interface for ControlLogix

The Honeywell DE Smart Transmitter Interface for ControlLogix (MVI56-DEM) integrates both Single and Multivariable Honeywell Transmitters operating in the DE mode with the Allen-Bradley ControlLogix backplane. The MVI56-DEM supports 16 DE channels. Supported instruments include:

• ST 3000 Smart Pressure Transmitter

• STT 3000 Smart Temperature Transmitter

• SMV 3000 Smart Multivariable Transmitter

• MagneW 3000 Smart Magnetic Flowmeter

• SCM 3000 Smart Coriolis Mass Flowmeter

• SGC 3000 Smart Gas Chromatograph

Features include:

• Functions as a DE protocol co-processor, off-loading all aspects of protocol communications from the ControlLogix processor

• Supports up to 16 single PV transmitters, 4 multivariable transmitters with 4 PVs each, or any mix of single or multivariable equaling 16 inputs

• Data analysis and integrity checking on the PV variable and the data base contents

• Full Read/Write access to instrument database

There are many benefits that can be derived from implementation of the DE

protocol in a plant application, including:

• Remote diagnostics to the instrument level

• High resolution PV value (32 bit floating point number)

• Remote PV and database integrity checking

• Remote Read/Write access to instrument data base

• Off-line instrument data base configuration

• Simplified loop checkout and switchovers

• Redundant I/O module connection to each channel
