Features:

  • Communication module
  • ControlLogix
  • Modbus Communication Module with Reduced Data Block
The MVI56-MCM communication module by Allen Bradley provides essential connectivity for ControlLogix systems, specifically designed for the 1756 backplane. It efficiently draws power with an 800 mA load at 5 V DC and minimal consumption of 3 mA at 24 V DC. This module allows for a flexible serial baud rate ranging from 110 bits per second to 115,200 bits per second and can be configured to handle data formats consisting of 7 to 8 data bits along with 1 to 2 stop bits with optional parity settings (none, odd, or even).

When it comes to environmental tolerance, the MVI56-MCM showcases impressive capabilities, functioning effectively from -40 °C to 85 °C, thus suitable for a variety of operating conditions. It can also withstand humidity levels of 5% to 95%, provided that it remains non-condensing. For safety and reliability, the module incorporates optical isolation from the backplane, rated at a typical 500 V. Status indicators provide real-time feedback on module status, backplane transfer, application, and serial communication activity.

The MVI56-MCM ProSoft Communication Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The ProSoft Technology MVI56-MCM is a Modbus Master/Slave serial module for ControlLogix, facilitating RS-232, 485, and 422 communication with 500V optical isolation. It supports 800 mA @ 5 VDC, operates between 0-60°C, and uses ladder logic for configuration. It was succeeded by the MVI56E-MCM (enhanced version) and is generally used in local chassis applications.

FAQs

  • What is MVI56-MCM?

    +
    The ProSoft MVI56-MCM is a Modbus Master/Slave module for ControlLogix, requiring 800mA @ 5V DC and supporting two serial ports (RS-232, 422, or 485).
  • What is the difference between MVI56-MCM and MVI56-MCMR?

    +
    The MCM version uses a larger I/O image (250 input/248 output words) and is preferred for local chassis use. The MCMR version uses a smaller I/O image (42 input/42 output words), making it ideal for remote racks over ControlNet to reduce bandwidth requirements.
  • What power does the module require?

    +
    It requires 800 mA at 5V DC and 3 mA at 24V DC provided directly by the ControlLogix backplane.
  • How do I handle more than 100 commands per port?

    +
    While each port's standard command list supports up to 100 entries, you can use Event Command control blocks to trigger additional Modbus commands directly from your ladder logic.
