MVI56-101M | ProSoft ControlLogix Master Network Communication Module

Functional Capabilities

The MVI56-101M (Part Number: MVI56-101M) is a single-slot solution designed to interface Allen-Bradley ControlLogix processors with specialized master-slave network protocols. By residing directly on the 1756 backplane, this module facilitates high-speed data exchange between the controller and field devices without the need for external protocol converters. It features two independent application ports, allowing for redundant or multi-drop network configurations in demanding industrial environments.

Detailed Technical Specifications

Port Configuration and Diagnostics

Effective system management is supported through dedicated hardware interfaces and visual feedback mechanisms.

• Application Ports (PRT1 & PRT2): Two independent serial ports for protocol-specific master communication.

• Configuration Port (CFG): Dedicated RJ45 port (RS-232 only) for module setup and debugging.

• Diagnostic LEDs: Integrated indicators for Module Status, Backplane Transfer, Application Port Activity, and Serial Traffic.

• Included Hardware: Every unit is supplied with an RJ45 to DB-9M adapter cable and a 6-foot RS-232 configuration cable to facilitate immediate commissioning.

Integration and Application FAQ

How is data mapped between the module and the ControlLogix CPU?Data transfer is handled via standard ladder logic or Add-On Instructions (AOI). The module uses a block transfer mechanism to move data between its internal database and the processor's controller tags.

Can the application ports be used for different protocols simultaneously?Typically, the MVI56-101M is dedicated to a specific protocol suite (such as specialized master network drivers), but both ports (PRT1 and PRT2) can operate independently to poll different slave devices on the same network type.

Is it possible to install this module in a remote I/O rack?Yes, the module can be placed in a remote ControlLogix rack connected via EtherNet/IP or ControlNet, provided the communication adapter supports discrete I/O data transfer for the module's data blocks.
