ProSoft MVI69-ADM C Programmable Application Development Module for CompactLogix

Description

The MVI69-ADM is a C-programmable Application Development Module designed for the Rockwell Automation CompactLogix platform. This single-slot solution enables engineers to develop and execute custom communication algorithms or specialized data processing routines directly on the 1769 backplane. It serves as a critical interface for legacy or proprietary protocols in industrial sectors such as oil refining, mining, and chemical processing. By offloading complex calculations and non-standard communication tasks from the main PLC CPU, the MVI69-ADM enhances system responsiveness and reliability. This module is essential for integrating specialized field devices, thereby reducing system complexity and minimizing potential downtime in highly customized automation environments.

Features

• Dedicated processor and memory independent of the CompactLogix controller to prevent impact on the main control loop.
• Three isolated serial ports supporting RS-232, RS-422, and RS-485 hardware standards.
• Seamless data transfer between the module's internal database and the processor memory via the 1769 backplane.
• Supports custom C-code execution for specialized data processing and proprietary protocol development.
• Standard 1769 module form factor for easy integration into existing CompactLogix racks.

Applications

The MVI69-ADM is typically deployed in industrial automation environments requiring custom protocol integration or specialized data processing. Common applications include interfacing with legacy flow computers, custom barcode scanners, specialized instrumentation, and proprietary serial field devices in oil and gas, chemical processing, and mining industries.

Technical Specifications

Installation Guidelines

• Ensure the CompactLogix rack power is disconnected before installing or removing the module.
• Slide the module into the designated 1769 slot until the backplane connector is fully seated and secure the module using the integrated locking mechanism.
• Use shielded communication cables for all serial connections to minimize interference in electrically noisy environments.
• Ensure proper grounding of the 1769 chassis to a common earth ground to maintain signal integrity.
• Verify that the module's current draw does not exceed the power supply capacity of the CompactLogix rack.

FAQ
