Description

PROSOFT MVI94-ADM Programmable Application Development Module

Product Dimensions：

The ProSoft Technology MVI94-ADM is an Application Development Module designed for the FLEX I/O platform (1794 series by Rockwell Automation). It enables system integrators and developers to write custom C-language algorithms to interface FLEX I/O racks with proprietary field devices and custom serial communication protocols.

Product Detailed Description

The MVI94-ADM acts as a programmable standalone co-processor residing directly on a FLEX I/O backplane. Rather than operating with a pre-configured protocol (like Modbus or ASCII), it provides an open C-development environment (using ProSoft’s C Development Kit). This allows developers to build tailored communication drivers or complex math routines right at the I/O level, bypassing the need to strain the main PLC’s processing overhead.

Technical Parameters

Product Advantages

• Custom Protocol Capabilities: Solves the challenge of connecting legacy, proprietary, or non-standard serial instruments (scales, barcode readers, specialized meters) to a modern control system.
• Offloads PLC Processing: Moves heavy string manipulation, custom checksum calculations, or complex algorithms away from the main controller to the local module.
• Compact FLEX I/O Form Factor: Integrates directly into distributed I/O racks, saving valuable space in control panels compared to bulky external protocol converters.
• Proven C Development Environment: Offers standard C-language libraries and API routines for easy access to serial ports and backplane memory buffers.

Important Considerations (Precautions)

• Programming Knowledge Required: Unlike standard plug-and-play ProSoft modules, the MVI94-ADM requires programming skills in C and familiarity with ProSoft’s development compiler tools.
• Legacy Lifecycle: The MVI94 product line is a mature/legacy series. Ensure firmware and C-compiler tools are compatible with your current development environment before starting new designs.
• Terminal Base Requirement: Requires a compatible FLEX I/O terminal base unit (such as 1794-TB3 or 1794-TB3S) for field wiring connections.
• Serial Cable Shielding: Proper shielding and grounding on the RS-232/422/485 serial ports are essential to prevent noise interference from disrupting custom data frames.

Product Applications

• Specialized Instrument Interface: Interfacing custom lab equipment, flow computers, or legacy weigh scales with ControlLogix/CompactLogix systems via FLEX I/O.
• Proprietary Building & HVAC Protocols: Connecting specialized building controllers or chiller systems using non-standard serial formats.
• Custom Serial Data Parsing: Reading, filtering, and parsing complex ASCII strings from RFID readers or barcode scanners before passing structured data to the PLC.
• Edge Pre-Processing: Performing localized mathematical calculations or signal filtering at distributed remote sites.
