3700-DEM

Important! Please Read!

Product Discontinuation Notice

3700-DEM will be discontinued effective 12/19/2006. This product is being replaced with ProLinx DEM, which is available now. Please review the Product End of Life Notification for important information on ordering, replacement and support for 3700-DEM.

The 3700-DEM for the PLC platform is a single slot module that supports digital communications with Honeywell smart transmitters.

The module supports 16 DE channels(3700), allowing both Single and/or multivariable Honeywell transmitters operating in the DE mode to be directly integrated with the A-B 1771 backplanes.

Supported Honeywell 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 and Benefits

Data exchange between the DEM module and the processor data table is performed using standard ladder logic commands (block transfer in the PLC). The data structure is automatically preset for the DE channels, allowing the module to be inserted into any PLC application with minimum ladder logic required.

• Configuration tools

  To ease configuration, an optional Windows program is available for each of the modules. These configuration tools will allow easy configuration of the individual DE channels, while also providing real time access to the PV values.

• The module is a DE protocol co-processor module, off-loading all aspects of protocol communications from the PLC. As such, the module performs many functions, including:
• Support for up to 16 single PV transmitters, 4 multivariable transmitters with 4 PVs each, or any mix of single or multivariable equaling 16 inputs
• Full read/write access to instrument database
• Data analysis and integrity checking on the PV variable and the data base contents
• Instrument database mismatch verification
• Support for redundant and non-redundant implementations
• All data communication between the module and the processor are performed using the block transfer commands over the backplane or via remote I/O. This allows various card configurations, including local and remote rack, as well as multiple cards per rack. In today's intelligent transmitters, there is often substantially more data available than can be transferred via a single analog input. 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 database
• Off-line instrument database configuration
• Simplified loop checkout and switchovers
• Redundant I/O module connection to each channel
