Description
The ProSoft Technology MVI56-HART is an industrial communication module designed for the Rockwell Automation ControlLogix platform, engineered to interface ControlLogix PACs directly with HART (Highway Addressable Remote Transducer) protocol field instruments.
In field deployments, this module connects via backplane rack insertion to manage multi-drop HART communication loops, enabling real-time process variable acquisition and device configuration for smart transmitters, flowmeters, and valve positioners without requiring external protocol converters.

Integration and Compatibility Notes
The MVI56-HART installs directly into any standard 1756 ControlLogix chassis slot and utilizes ladder logic Add-On Instructions (AOIs) for seamless data transfer within Studio 5000 / RSLogix 5000 environments.
- Wiring and Isolation: Requires dedicated analog signal wiring with HART-compatible isolating barriers or termination panels if loop power is shared with control system I/O cards.
- Configuration Tool: Module parameters, primary/secondary variable mapping, and device polling cycles are configured using ProSoft Configuration Builder (PCB) software via the module’s front-panel configuration port.
- Chassis Placement: Can be placed in any local ControlLogix chassis or remote chassis linked via EtherNet/IP or ControlNet backplane bridging networks.
Frequently Asked Questions
Q: Does the MVI56-HART module supply loop power to connected field transmitters? A: No. The module interfaces with existing 4 to 20 mA current loops. Field instruments require an independent external power supply or loop power source.
Q: Can this module pass HART data through to asset management software like AMS Device Manager? A: Yes. By utilizing ProSoft’s HART pass-through routing features, engineering workstations can communicate with field devices for diagnostics and parameter tuning.
Q: How many devices can be connected to a single module? A: The module features 2 independent channels, each capable of supporting up to 15 devices in a multi-drop configuration, allowing a maximum of 30 HART devices per card.
