Description
Product Name: 2711P-RN20 Allen Bradley Programmable controller
Product details:
Allen-Bradley offers a broad portfolio of PLCs, categorized into families designed for various application sizes and complexities. The primary modern families fall under the Logix platform, which shares a common control engine and development environment (Studio 5000 Logix Designer).
1. Product Details and Specifications (Product Families)
| Product Family | Target Application | Key Specifications/Characteristics |
| ControlLogix | Large-scale, high-performance, and process control applications. Mission-critical systems. | – Modular: Chassis-based, allowing high I/O density and module selection. – Performance: Highest processing speed and memory capacity. – Redundancy: Supports redundant controllers, power supplies, and communication for high availability. – Networking: Extensive support for EtherNet/IP, ControlNet, DeviceNet. – I/O: Capable of managing thousands of distributed I/O points. |
| CompactLogix | Mid-range, stand-alone machine, and small-to-mid-sized system control. | – Integrated: Often rackless, with the controller integrated with a power supply and I/O. – Scalability: Flexible I/O options via local expansion modules and distributed I/O. – Motion: Built-in motion control capabilities. – Networking: Strong support for EtherNet/IP. – I/O: Supports a significant number of local and distributed I/O modules (e.g., up to 30 local modules depending on the model). |
| MicroLogix/Micro800 | Small, low-cost applications, stand-alone machines, and simple process control. | – Compact: All-in-one ‘brick’ style (Micro800 is the modern successor). – Cost-Effective: Entry-level pricing. – Programming: Often uses Connected Components Workbench (CCW) software, which is simpler and free for basic models. – I/O: Limited, but expandable with plug-in or expansion modules. – Connectivity: Basic models often include built-in Ethernet and serial ports. |
Note: Specific technical parameters like CPU speed, memory size (e.g., 5MB, 10MB, etc.), and I/O capacity vary widely within each family and are model-dependent.
2. Product Advantages (Key Strengths)
- Reliability and Durability: Allen-Bradley PLCs are known for their robust design, making them suitable for harsh industrial environments, including extreme temperatures, vibration, and electrical noise. They are designed for a long operational lifespan.
- Scalability: The Logix platform is highly scalable, allowing users to move between ControlLogix and CompactLogix with minimal re-training and code migration due to the common control engine and programming software.
- Integrated Architecture: Rockwell Automation’s focus on a unified platform (Integrated Architecture) allows seamless integration with other Allen-Bradley products like Human-Machine Interfaces (HMIs), drives, and motion control systems.
- Programming Ease: Supports standard PLC programming languages (IEC 61131-3) including Ladder Logic, Structured Text, Function Block Diagram, and Sequential Function Chart, primarily using the powerful Studio 5000 Logix Designer software.
- Strong Support and Ecosystem: Backed by Rockwell Automation, a global leader, with extensive documentation, training, and a worldwide network of distributors and system integrators.
- EtherNet/IP: Strong proponent and developer of the EtherNet/IP industrial protocol, facilitating high-speed, standard Ethernet communications across the plant floor.
3. Considerations and Caveats (Important Notes)
- Cost: Allen-Bradley PLCs, especially the high-end ControlLogix systems, often have a higher initial hardware and software cost compared to some competitors.
- Proprietary Software: While they use standard languages, the primary, full-featured development software (Studio 5000 Logix Designer) is proprietary and requires licensing.
- Complexity: For very small, simple, and low-budget applications, the full Logix platform might be an overkill in terms of features and learning curve. The Micro800 series is designed to address this.
- Migration: While Rockwell supports a migration path from older, obsolete platforms (like PLC-5 and SLC 500), upgrading legacy systems can require significant planning and capital investment.
4. Product Applications
Allen-Bradley PLCs are utilized across nearly every industry for automation and control. Common applications include:
- Automotive: Assembly line control, robot integration, painting processes.
- Food & Beverage: Batching, mixing, packaging, filling, and continuous process control.
- Oil & Gas: Pipeline monitoring, pump and compressor station control, wellhead automation.
- Pharmaceuticals: Validation, recipe management, precise process control in cleanroom environments.
- Manufacturing: High-speed material handling, machine control, packaging systems, CNC integration.
- Water/Wastewater: Pump control, filtration processes, telemetry and remote monitoring (SCADA systems).
- Energy: Power generation (boiler control, turbine control) and distribution systems.
