Information About MVI56-MCM

The MVI56-MCM belongs to ProSoft’s line of communication modules developed specifically for the ControlLogix platform. Supporting both Modbus RTU and ASCII protocols, it enables bidirectional communication with a wide range of third-party instruments, drives, and controllers. The module requires a ControlLogix processor and operates in either a local chassis or a remote rack connected over EtherNet/IP or ControlNet. Designed for demanding applications, it includes onboard configuration tools, dedicated serial ports, and pre-assembled cabling for rapid deployment. Suitable for hazardous locations rated Class I, Division 2, the MVI56-MCM operates across industrial temperature ranges and provides robust data handling with recommended 256 MB RAM and 100 MB disk space for configuration and logging.

Key Features

  • Modbus Master/Slave Support: Enables connectivity with Modbus RTU/ASCII devices across diverse automation systems.
  • ControlLogix Integration: Occupies a single rack slot and communicates directly via the backplane.
  • High Backplane Power Capacity: Requires 800 mA to ensure stable data throughput.
  • Dual Serial Ports: Provides two independent Modbus channels for flexible network architectures.
  • Hazardous Location Approved: Certified for Class I, Division 2, Groups A–D environments.
  • Local or Remote Rack Installation: Operates in remote chassis via EtherNet/IP or ControlNet.
  • Comprehensive Configuration Tools: Includes cables and adapter hardware for easy commissioning.
  • Industrial Temperature Rating: Supports operation from 32 to 140 °F for harsh environments.

The MVI56-MCM delivers the reliability and precision required for integrating Modbus communication into ControlLogix-based automation systems.

Frequently Asked Questions about MVI56-MCM
Question: What is the primary function of the MVI56-MCM module?
Date Update:06/06/2025
Answer:

The MVI56-MCM is a Modbus communication module designed to integrate Modbus-compatible devices into a ControlLogix control system. It allows data exchange between Rockwell Automation controllers and Modbus RTU/ASCII devices such as drives, meters, or PLCs. This facilitates seamless communication across heterogeneous automation environments. It plays a key role in bridging Allen-Bradley systems with legacy Modbus networks. It supports both Master and Slave modes of operation.

Question: What kind of power supply does the MVI56-MCM require?
Date Update:06/06/2025
Answer:

The MVI56-MCM requires 800 milliamps of backplane power supplied by the ControlLogix chassis. It draws this power directly through the rack slot, without requiring an external power source. The ControlLogix power supply must be adequately sized to support all installed modules. Proper calculation of total rack load is essential. Overloaded power supplies can cause module faults.

Question: How does the MVI56-MCM connect to the ControlLogix processor in a remote rack?
Date Update:06/06/2025
Answer:

In a remote rack configuration, the MVI56-MCM communicates with the ControlLogix processor using EtherNet/IP or ControlNet. These networks ensure high-speed data transfer and integration across distributed systems. The ControlLogix processor must be configured to recognize the module remotely. Remote connectivity allows for flexible system architectures. Configuration tools like RSLogix 5000 or Studio 5000 are typically used.

Question: What comes included with the MVI56-MCM module?
Date Update:06/06/2025
Answer:

The module is typically shipped with necessary Modbus communication cables and an adapter device. These accessories simplify the installation and setup process. Documentation and software tools are also provided or available online. The inclusion of accessories reduces the need for sourcing additional components. Always verify package contents before installation.

Question: What are the dimensions of the MVI56-MCM module?
Date Update:06/06/2025
Answer:

The MVI56-MCM module has typical ControlLogix single-slot dimensions, approximately 145 x 35 x 140 mm (5.7 x 1.38 x 5.5 inches). It fits into a single chassis slot in a ControlLogix rack. Its size ensures compatibility with compact and standard ControlLogix enclosures. These dimensions make it ideal for control panels with limited space. Installation follows standard ControlLogix mounting practices.
