Description

The ProSoft MVI56-MCMR is a specialized Modbus Master/Slave communication module designed for the Rockwell Automation ControlLogix platform. It is specifically optimized for remote chassis applications, such as those utilizing ControlNet, where bandwidth optimization is critical. By utilizing a reduced 42-word Input/Output image, the MVI56-MCMR minimizes bandwidth impact compared to standard modules, making it an ideal choice for complex, distributed control systems.

Features

  • Optimized for Remote Racks: Designed for ControlNet and remote chassis environments to reduce bandwidth consumption.
  • Dual Serial Ports: Features two configurable serial ports supporting RS-232, RS-422, and RS-485 physical standards.
  • Flexible Baud Rates: Supports communication speeds ranging from 110 baud up to 115,200 baud.
  • Configuration: Configured via ProSoft Configuration Builder (PCB) with integration into RSLogix 5000 using Add-On Instructions (AOI).
  • Visual Diagnostics: Integrated LED indicators provide real-time status updates for communication and module health.

Applications

  • Oil and Gas: Data acquisition for pipelines and offshore platform monitoring.
  • Water and Wastewater: Managing data exchange between control systems and remote monitoring stations.
  • Food Processing: Integration of automated production line equipment.
  • Mining, Pulp, and Paper: Connecting legacy serial equipment to modern ControlLogix architectures.

Installation Guidelines

  • Power Off: Always remove power from the ControlLogix chassis before inserting or removing the module to prevent electrical damage.
  • Slot Placement: The module occupies one slot in the ControlLogix rack. Ensure it is seated firmly and the locking tab is engaged.
  • Jumper Configuration: Physical serial standards (RS-232/422/485) are selected via jumpers located at the bottom of the module. Ensure these are set correctly before installation.
  • Wiring: Use a minimum phase wire size of 1.3 mm squared. Ensure proper shielding for serial cables to minimize EMI in industrial environments.
  • Grounding: Follow standard industrial grounding practices for the chassis to ensure signal integrity.

FAQ

What is the primary difference between MVI56-MCM and MVI56-MCMR?

The MVI56-MCMR is optimized for remote chassis applications by using a reduced 42-word I/O image to save bandwidth, whereas the MVI56-MCM uses a larger 250-word image. Additionally, the MCMR does not support the Modbus Pass-Thru feature.

How is the module configured?

The MVI56-MCMR is configured using an offline file created in ProSoft Configuration Builder (PCB) and integrated into the processor using Add-On Instructions (AOI) within RSLogix 5000.

Can I prevent data loss during a power cycle?

Yes, you can use the Initialize Input Image parameter to cache values from the processor so they are not reset to zero during a module reset or power loss.
