ProSoft MVI56-HART HART Master Communication Module
Configured for multi-channel field instrument integration within Rockwell Automation ControlLogix architectures, the ProSoft MVI56-HART (MVI56-HART HART Protocol Communication Module) provides direct physical/electrical execution. It coordinates digital HART communication packets across four independent master channels, managing up to 60 multidrop field devices and routing process variables directly into the processor backplane memory without intermediate gateway hardware.
Suffix Breakdown & Model Matrix
The module identifier MVI56-HART designates the ProSoft communication processor optimized for 1756 ControlLogix chassis integration. Standard hardware configuration includes four independent HART master communication channels and an internal database supporting 5000 registers for backplane data exchange.

Intrinsic Safety and DIN-Rail Mounting Stability
The module relies on robust backplane bus connections within the ControlLogix chassis, maintaining mechanical stability under high-vibration industrial conditions. Surge voltage protection limits safeguard internal transceiver circuits against transient voltage spikes originating from long field cabling runs. Protocol conversion latencies remain constrained within strict deterministic limits to ensure real-time data synchronization across connected network loops.
Frequently Asked Questions
Q: What is the maximum backplane current draw required by the MVI56-HART module when installed in a 1756 chassis?
A: The module consumes approximately 850 mA from the 5 VDC backplane power supply during normal multi-channel operation.
Q: Does the module support hot-swapping within an active ControlLogix chassis?
A: Inserting or removing the module while the chassis backplane is energized requires strict adherence to local electrical safety permits and processor I/O configuration protocols to prevent data corruption.
Field Installation Guidelines
Insert the module directly into any available single slot of a Rockwell Automation 1756 ControlLogix chassis, ensuring the backplane connector aligns properly before securing the top and bottom latching tabs. Connect field wiring from HART instruments to the removable terminal block, observing proper shielding techniques. Terminate cable shield drain wires to the cabinet earth ground bar to minimize electromagnetic interference across analog signal loops.
