Product Details

Product Overview

The MVI46-MCM is a ProSoft Technology module specifically engineered to integrate seamlessly with the Allen-Bradley SLC 500 platform. This single-slot solution functions as a gateway between the SLC backplane and Modbus serial networks. By acting as either a Modbus Master or Slave, the MVI46-MCM (PN: MVI46-MCM) enables modular processors to communicate with diverse field devices such as power monitors, variable frequency drives (VFDs), and remote terminal units (RTUs).

Technical Specifications

  • Manufacturer Allen-Bradley / ProSoft Technology

  • Product Series SLC 500 Modular Hardware

  • Model Number MVI46-MCM

  • Module Type Modbus Master/Slave Network Interface

  • Slot Requirement Single Slot (Local or Extended Racks)

  • Processor Compatibility SLC 5/02 or later (M0/M1 file capable)

  • Backplane Current Load 800 mA @ 5.1 VDC

  • Communication Ports Two (2) RJ45 RS-232/422/485 Application Ports

  • Configuration Port One (1) RJ45 (RS-232 only)

  • Maximum Registers 5000 16-bit registers

  • Command Capacity Up to 100 commands per port

  • Data Transfer Method Ladder Logic through M0/M1 files

  • Operating Temperature 32°F to 140°F (0°C to 60°C)

  • Vibration/Shock 30g Operational Shock

  • Relative Humidity 5% to 95% (Non-condensing)

  • Shipping Weight 3.00 lbs (1.36 kg)

Hardware Interface and Status

The module features a robust diagnostic display via front-panel LED indicators to assist in rapid troubleshooting:

  • Module Status Overall health and initialization

  • Backplane Transfer Data exchange status with the SLC CPU

  • Application Status Configuration and port-specific health

  • Serial Activity Real-time TX/RX monitoring and Error LEDs

Configuration and Integration

The MVI46-MCM requires specific setup within the RSLogix 500 environment. Because it utilizes M0 and M1 files for high-speed data transfer, the user must ensure the SLC processor supports these file types. The two application ports can be configured independently, allowing one port to operate as a Master while the other functions as a Slave on a completely separate Modbus network.

Frequently Asked Questions

  • Can the MVI46-MCM be placed in a remote I/O rack?

    No, the module is only supported in local or extended local racks. It cannot be used in remote racks over 1747-ASB or similar remote I/O adapters.

  • What cable is required for the configuration port?

    The module typically ships with an RJ45 to DB-9M cable specifically wired for RS-232 configuration tasks.

  • How many Modbus devices can I connect to a single port?

    In RS-485 mode, you can connect up to 32 nodes without a repeater. With repeaters, the Modbus protocol supports up to 247 slave addresses.
