Description
Product Name: 1321-3RA55-B Allen Bradley Controller module
Product details:
Allen-Bradley offers three primary, modern controller families in the Logix platform, designed to cover applications from small, simple machines to large, complex, and mission-critical systems:
| Product Series | Target Application Size | Key Characteristics | Programming Software |
| Micro800 Series | Entry-level / Small Machines | Compact, low-cost, fixed and plug-in I/O modules, excellent for standalone machines. | Connected Components Workbench (CCW) |
| CompactLogix™ Series | Small to Mid-Sized Applications | Integrated motion, safety options, high-performance for complex machines and small process control. Supports a moderate number of I/O. | Studio 5000 Logix Designer |
| ControlLogix® Series | Large-Scale / Plant-Wide Systems | Modular, high-performance, robust redundancy options, massive I/O capacity, best for mission-critical and complex process control. | Studio 5000 Logix Designer |
(Note: Older series like MicroLogix and SLC 500 are considered legacy, but are still in use in many installations.)
2. General Product Parameters (Specifications)
Specific parameters vary widely by the model within each series, but common specifications include:
- I/O Capacity: Ranging from a few dozen points (Micro800) to thousands of distributed I/O points (ControlLogix).
- Memory: Typically ranging from a few KB to over 50 MB (ControlLogix) for user programs and data.
- Processor Speed (Performance): Measured in execution speed for program logic, with ControlLogix offering the highest throughput for demanding applications.
- Communication Protocols: Extensive support for industrial protocols, primarily EtherNet/IP, as well as ControlNet, DeviceNet, and serial communication options.
- Programming Languages: Supports IEC 61131-3 standard languages: Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), and Sequential Function Chart (SFC).
- Integrated Safety: Many CompactLogix and ControlLogix controllers offer Integrated Safety (Safety PLCs) for compliance with safety standards.
3. Product Advantages (Key Benefits)
| Advantage | Description |
| Reliability & Durability | Built to withstand harsh industrial environments, including high temperature, vibration, and electrical noise. Minimizes unexpected downtime. |
| Scalability & Modularity | The Logix platform allows users to scale from small to very large systems using the same core programming environment (Studio 5000), reducing engineering and training costs. |
| Seamless Integration | Excellent integration with other Rockwell Automation products (HMI, Drives, Safety, Software), leveraging the Logix and FactoryTalk architectures for a unified control system. |
| Integrated Motion Control | High-performance controllers (CompactLogix/ControlLogix) allow motion control (servo/stepper) to be seamlessly integrated within the standard control program. |
| Common Development Environment | The use of Studio 5000 for both mid-range and high-end PLCs simplifies programming, troubleshooting, and maintenance for technicians. |
4. Important Considerations (Notes/Precautions)
- Software Licensing: Rockwell Automation’s advanced software (Studio 5000 Logix Designer) requires purchasing a license, which can be a significant upfront cost.
- Platform Selection: Choosing the correct controller family (Micro800, CompactLogix, ControlLogix) based on current and future I/O count, processing speed, and required features (like motion or redundancy) is critical to avoid under- or over-specification.
- Legacy vs. Modernization: Older series (SLC 500, PLC-5) are often obsolete and require modernization to a modern Logix platform to ensure long-term support and access to new features.
- Networking: Proper design of the EtherNet/IP network is crucial for system performance, especially in large-scale applications with integrated drives and safety.
5. Product Applications (Use Cases)
Allen-Bradley PLCs are utilized across nearly all industrial sectors:
- Manufacturing & Assembly: Controlling high-speed assembly lines, robotic cells, packaging, and material handling systems.
- Process Industries: Managing batching systems, continuous process control (e.g., mixing, chemical reactions), and temperature/flow regulation in Oil & Gas, Chemical, and Pharmaceutical plants.
- Water & Wastewater: Controlling pumping stations, filtration processes, and chemical dosing systems.
- Energy: Monitoring and control of power generation (turbines, generators) and distribution systems.
- Automotive: Body shop, paint shop, and final assembly automation, often with high-speed synchronization and safety requirements.
- Food & Beverage: Control of filling, bottling, and clean-in-place (CIP) processes, meeting stringent hygiene requirements.
