A Reliance Processor Module (such as those from the AutoMate or AutoMax series) is the "brain" of an industrial control system. It contains a microprocessor, memory, and communication circuitry to perform various control tasks.

Functionality: The processor module continuously reads input signals from sensors and other devices connected through I/O modules. It then executes a stored control program (often written in ladder logic, but sometimes in BASIC or control block languages) based on these inputs. Finally, it sends output signals to actuators and other field devices via output modules, thereby automating specific machinery or processes. It also handles data management, communication with other systems (like HMIs or SCADA), and self-diagnostics.
Architecture: Reliance processor modules often utilized a modular, rack-based architecture, allowing them to be installed in a chassis alongside power supply modules, I/O modules, and communication modules. Some advanced systems supported multi-processing, enabling multiple processor modules to share tasks within the same rack for increased performance or redundancy.
Program and Data Storage: These modules featured non-volatile memory to retain the application program and data even during power loss. This ensured that the control system could resume operation without reprogramming after a power interruption.

Product Parameters

Specific parameters would vary based on the particular model and series (e.g., AutoMate 15, AutoMate 40, AutoMax 7010). However, common parameters include:

Processor Type: The specific microprocessor used (e.g., Motorola 68000 for some AutoMate 40X modules).
Memory Size: Capacity for program logic and data, often specified in K x 16 (e.g., 8K x 16, expandable to 104K x 16 for AutoMate 40X).
Execution Speed: How fast the processor can scan and execute the control program, typically measured in milliseconds per K-ladder (ms/K). Faster speeds enable more complex control and quicker response times.
I/O Addressing Capability: The maximum number of digital and analog I/O points the processor can manage (e.g., up to 1024 digital I/O for some AutoMate 40X models).
Communication Ports: Built-in serial ports (e.g., RS-232, RS-485) for programming, HMI connection, or network integration. Some higher-end AutoMax processors included built-in DCS-Net and Allen-Bradley Remote I/O ports.
Power Consumption: The electrical power required for the module's operation.
Operating Temperature: The ambient temperature range within which the module is designed to operate reliably (typical industrial ranges).
Firmware/Operating System: The version of the operating system that governs the processor's functions, often loadable for future enhancements.

Product Advantages

Robustness and Reliability: Reliance processor modules were engineered for the demanding conditions of industrial environments, ensuring consistent and dependable operation, which is critical for minimizing downtime in automated processes.
Distributed Control System (DCS) Capabilities: The AutoMax series, in particular, offered features that allowed for distributed control, enabling control functions to be spread across multiple processors and racks, enhancing system resilience and scalability.
Multi-language Programming: Support for multiple programming languages like ladder logic, BASIC, and control block programs provided flexibility for developers to choose the most effective language for different parts of an application.
Multi-processing and Multi-tasking: Advanced features like multi-processing (adding processor power within the same rack) and multi-tasking (breaking software into logical parts with assigned priorities) simplified development and improved system performance.
Network Capabilities: Integrated networking features (e.g., DCS-Net, remote I/O) facilitated easy data sharing between different control units and allowed I/O to be placed close to equipment, reducing wiring costs.
Built-in Diagnostics: On-board status LEDs and comprehensive diagnostics aided in rapid troubleshooting, contributing to higher system availability.

Important Considerations

Obsolescence: As legacy products, Reliance processor modules are often difficult to find new. Support, spare parts, and specialized expertise may be limited, necessitating a strategy for maintenance or migration to modern control platforms.
Programming Environment: Older programming software and hardware interfaces might be required, which can be challenging to set up on modern computing systems.
Compatibility: Ensure the processor module is compatible with existing I/O modules, power supplies, and communication networks within the current automation system.
Documentation: Access to original manuals and documentation is crucial for understanding specific parameters, installation procedures, and troubleshooting.
Cybersecurity: For older systems connected to networks, it's vital to assess and mitigate cybersecurity risks, as these systems may lack modern security features.

Product Applications

Reliance processor modules were deployed across a vast array of industrial applications, forming the core of automation systems:

Automated Manufacturing: Controlling assembly lines, discrete manufacturing processes, material handling systems, and robotic cells.
Process Control: Regulating continuous processes in industries such as chemicals, oil and gas, food and beverage, and pharmaceuticals, including temperature, pressure, and flow control.
Machine Control: Providing logic and control for complex machinery like packaging equipment, printing presses, and specialized production machines.
Motion Control: Integrated within or alongside drive systems to provide precise control over motor speed, torque, and position for applications requiring synchronized motion.
Power Generation and Utilities: Used in older power plants for auxiliary control systems, turbine control, and balance-of-plant automation.
Water and Wastewater Management: Controlling pumps, valves, and treatment processes in municipal and industrial water facilities.
