Reliance Multi-Function Processor Modules, historically part of the Reliance Electric AutoMax and other control systems, were the central processing units (CPUs) responsible for executing control logic, managing I/O, and facilitating communication within industrial automation applications. They were designed to provide robust and reliable control in diverse manufacturing and process environments.

Product Details

Core Function: These modules served as the "brain" of the control system, executing programs written in various industrial programming languages to automate machine operations, processes, and data management.
Integrated Capabilities: The "multi-function" aspect implies that these modules often combined several functionalities beyond just core processing, such as:

Logic Control: Executing PLC-like ladder logic, control block diagrams, or BASIC programs.
Communication Management: Handling various communication protocols (e.g., peer-to-peer, network communication to HMIs, other PLCs, or supervisory systems).
Data Processing: Performing calculations, data logging, and alarm management.
Motion Control (in some versions): Providing capabilities for precise control of motors and drives.

Architecture: Typically designed to be plugged into a rack or chassis, where they would communicate with and control other I/O, power, and specialized modules. Some systems allowed for multiple processor modules in a single rack for redundancy or distributed control.

Product Parameters (Examples based on historical models like AutoMax Processors)

Microprocessor: Often based on industry-standard microprocessors (e.g., Motorola 68020 in some AutoMax modules).
CPU Speed: Measured in MHz (e.g., 8 MHz, 25 MHz for older models).
Memory:

Program Memory: For storing the control logic program (e.g., 16KB, 256KB, 512KB parity RAM).
Data Memory: For storing variables, registers, and other data.

Programming Languages Supported:

Ladder Logic
Control Block (function block diagrams)
BASIC (for more complex algorithms or data manipulation)

Communication Ports:

RS-232 for local programming and diagnostics.
Network interfaces (proprietary or standard industrial protocols like Ethernet, depending on the generation and specific module).

Faceplate Features:

LED indicators for power, run, fault, and communication status.
Fault code indicators for easier troubleshooting.
User-replaceable battery backup for retaining data in RAM during power loss.

Power Supply: Typically derived from the backplane of the rack, powered by a separate power supply module (e.g., 24V DC).
Operating Temperature: Designed for industrial temperature ranges (e.g., 0°C to 60°C).

Product Advantages

Robustness and Reliability: Built for harsh industrial environments, offering high uptime and stable operation.
Integrated Control: Ability to handle complex control logic, I/O management, and communication within a single module or system.
Programming Flexibility: Support for multiple programming languages allowed engineers to choose the most suitable method for different parts of the application.
Scalability (within their architecture): Modular design allowed for expanding I/O and adding specialized modules as needs evolved.
Diagnostic Capabilities: Onboard diagnostics and LED indicators aided in troubleshooting and maintenance.
Proven Technology: For many years, Reliance Electric systems were a cornerstone of industrial automation, with a large installed base and a strong reputation.

Important Considerations

Legacy Systems: Many Reliance Multi-Function Processor Modules are now considered legacy or obsolete products. This means:

Availability: New modules can be difficult or impossible to find; reliance on surplus or refurbished parts is common.
Support: Direct manufacturer support from the original "Reliance Electric" is generally not available, though Rockwell Automation may offer limited support for specific transitions or modern equivalents. Third-party support and repair services are crucial.
Compatibility: Integrating these older modules with modern control systems can be challenging due to differing communication protocols and software.

Programming Software: Requires specific legacy programming software, which may only run on older operating systems.
Maintenance: Understanding the specific nuances of the module (e.g., battery backup for RAM) is vital for proper maintenance.
Migration Planning: For critical applications, consider a long-term migration strategy to modern control platforms to ensure continued operability and access to contemporary features and support.

Product Applications (Historical and Current Legacy Use)

Continuous Process Control:

Chemical processing plants
Oil and gas facilities
Power generation plants
Water and wastewater treatment

Discrete Manufacturing:

Packaging machinery
Material handling systems (conveyors, robotic cells)

Machine Control:

Various standalone machines requiring sophisticated automation.

Pulp and Paper Industry:

Control of paper machines and associated processes.

Metals Industry:

Rolling mills, furnace control.
