Description

The ProSoft MVI56-DFCM is a specialized communication module designed to provide DF1 protocol connectivity for Rockwell Automation ControlLogix platforms. This module acts as a high-performance interface, allowing the ControlLogix processor to communicate with devices supporting the DF1 protocol, including both Master and Slave configurations. It occupies a single slot in the ControlLogix rack and facilitates seamless data exchange via ladder logic, making it an essential component for legacy device integration and serial communication expansion in industrial automation systems.

Features

• Supports both DF1 Master and Slave modes for flexible network integration.
• Occupies a single slot in any local or remote ControlLogix I/O rack.
• Configurable baud rates ranging from 110 to 115,200 baud.
• Supports read/write command lengths up to 125 words.
• User-configurable memory mapping for optimized data throughput.
• Robust design with 30G operational shock rating for harsh industrial environments.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix rack is powered down before inserting or removing the MVI56-DFCM module to prevent electrical damage.
• Slide the module into any available slot in the ControlLogix chassis and secure it using the integrated locking mechanism.
• Use shielded serial cabling for all DF1 connections to minimize electromagnetic interference (EMI).
• Ensure proper grounding of the ControlLogix chassis to a common earth ground to maintain signal integrity.
• Configure the module parameters via the ControlLogix processor ladder logic and ProSoft configuration software prior to full network deployment.

FAQ

What is the primary function of the MVI56-DFCM?
