Description
PROSOFT MVI56-ADM Development Module
Product Dimensions:
The ProSoft Technology MVI56-ADM (C Programmable Application Development Module) is a powerful, ControlLogix-based communication module. It allows developers to create custom communication interfaces and protocols using the C programming language, essentially acting as a “computer” inside an Allen-Bradley ControlLogix rack.
Product Description
The MVI56-ADM is designed for specialized applications where a standard, “off-the-shelf” communication protocol (like Modbus or EtherNet/IP) does not exist or does not meet specific requirements. It provides two serial ports and a powerful development environment, allowing the module to interface with proprietary devices such as barcode scanners, scales, or legacy industrial hardware.

Key Advantages
-
Customization: Enables the creation of unique protocols that are not available in standard libraries.
-
High Performance: Direct access to the ControlLogix backplane ensures fast data exchange with the PLC processor.
-
Space Saving: Eliminates the need for external protocol converters or “black boxes” by integrating the solution directly into the PLC rack.
-
Security: Since the code is compiled and stored on the module, it protects intellectual property and prevents unauthorized tampering with the communication logic.
-
Industrial Hardening: Designed to withstand harsh electrical and environmental conditions better than a standard PC or gateway.
Product Applications
-
Legacy Device Integration: Connecting older equipment (e.g., proprietary CNC machines) that uses non-standard serial strings.
-
Complex Data Processing: Performing heavy mathematical calculations or data sorting locally on the module to reduce the PLC scan time.
-
Specialized Sensors: Interfacing with precision scales, RFID readers, or lab equipment that requires specific handshaking sequences.
-
Security Encryption: Implementing custom encryption or checksum algorithms for sensitive data transmission.
Important Considerations (Notes)
-
Programming Expertise: This module requires a solid understanding of C programming and serial communication. It is not a “plug-and-play” device like a Modbus module.
-
API Libraries: Users must use ProSoft’s provided libraries (ADM API) to handle the backplane communication between the module and the ControlLogix CPU.
-
Power Consumption: Ensure the ControlLogix power supply can handle the additional 800 mA draw from the backplane.
-
Firmware: Always verify that the module firmware is compatible with the version of RSLogix 5000 / Studio 5000 you are using.
