The Micro800 series is a family of programmable logic controllers (PLCs) developed by Rockwell Automation. These PLCs are designed for small to mid-sized applications and are part of the Allen-Bradley brand, which is a subsidiary of Rockwell Automation. The Micro800 series is known for its compact size, affordability, and ease of use, making it suitable for a variety of industrial and commercial automation tasks.
Key features and characteristics of Micro800 PLCs include:
Allen Bradley Micro820 PLC Systems are physically compact, making them suitable for applications with limited space or where a smaller form factor is essential.
- Space Efficiency: Micro800 PLCs are designed to occupy minimal space in control panels or wherever they are installed. This is particularly advantageous in applications where space is limited, and a smaller footprint is crucial.
- Panel Mounting: The compact size allows for easy integration into control panels and cabinets. This is beneficial for applications where the available space for housing control equipment is constrained, such as in small machinery or control enclosures.
- DIN Rail Mounting: Many Micro800 PLCs are designed for DIN rail mounting. DIN rail is a standard mounting rail for industrial control equipment, and the compact design of Micro800 PLCs makes them well-suited for this type of installation. It simplifies the mounting process and helps in organizing control components efficiently.
These PLCs are often more budget-friendly compared to larger and more complex PLC systems, making them a cost-effective solution for smaller automation projects.
- Affordable Entry Point: Micro800 PLCs are known for providing a cost-effective entry point into the world of programmable logic controllers. The initial investment required to implement a Micro800-based control system is often lower compared to larger and more complex PLC systems.
- Economical Hardware: The hardware components of Micro800 PLCs are designed to be cost-effective while still offering the necessary functionality for smaller automation projects. This affordability makes Micro800 PLCs attractive for applications where budget constraints are a consideration.
- Compact Design and Integration: The compact design of Micro800 PLCs not only contributes to their versatility but also helps in cost savings. The smaller form factor often leads to reduced material costs, and the integrated I/O options minimize the need for additional external components.
Micro800 PLCs typically come with integrated I/O (Input/Output) options, simplifying the setup process and reducing the need for additional hardware components.
- Built-In I/O Modules: Micro800 PLCs often come with integrated I/O modules, meaning that some of the input and output points are directly incorporated into the PLC hardware. This can include digital and analog inputs and outputs, and sometimes even specialty I/O types.
- Space Efficiency: The integration of I/O directly into the PLC reduces the need for external I/O modules or racks. This contributes to a more compact design and helps save space in control panels or cabinets.
- Simplified Wiring: With integrated I/O, the wiring complexity is reduced. Since certain I/O points are part of the PLC itself, there is less need for extensive wiring between external I/O modules and the PLC. This not only simplifies the installation process but also contributes to a cleaner and more organized control system.
Embedded Communication Ports:
he Micro800 series often includes embedded communication ports, allowing for easy connectivity with other devices such as human-machine interfaces (HMIs), sensors, and other automation equipment.
- Direct Connectivity: Micro800 PLCs typically come with one or more embedded communication ports, such as serial ports (RS-232/RS-485) or Ethernet ports. These ports enable direct communication with various devices, including human-machine interfaces (HMIs), other PLCs, sensors, and other industrial equipment.
- Ethernet Communication: Ethernet ports are common in Micro800 PLCs, facilitating communication over industrial Ethernet protocols. This is essential for connecting the PLC to a larger industrial network, enabling data exchange with other PLCs, supervisory control and data acquisition (SCADA) systems, and enterprise-level systems.
- Serial Communication: Serial ports, such as RS-232 and RS-485, provide options for connecting to legacy devices or equipment that use serial communication protocols. This can be useful in scenarios where older equipment needs to be integrated into a modern control system.
Rockwell Automation provides programming software called Connected Components Workbench (CCW) for Micro800 PLCs. CCW offers a user-friendly environment for programming, configuring, and monitoring the PLCs
- User-Friendly Interface: CCW is designed with a user-friendly interface that makes it accessible to both beginners and experienced programmers. The software provides a workspace where users can create, edit, and manage their PLC programs.
- Integrated Development Environment (IDE): CCW serves as an integrated development environment, offering tools and features for programming, configuration, and troubleshooting Micro800 PLCs. It includes a range of editors and wizards for various programming tasks.
- Online and Offline Programming: Users can program Micro800 PLCs both online and offline. Online programming allows users to make changes to the PLC program while it is running, facilitating real-time adjustments. Offline programming, on the other hand, enables users to develop and test programs without being connected to the actual PLC.
Some models within the Micro800 series offer modular expansion options, allowing users to expand the capabilities of the PLC by adding additional I/O modules or communication modules as needed.
Micro800 PLCs are suitable for a range of applications, including simple control tasks, machine automation, and process control in industries such as manufacturing, automotive, and food and beverage.
Support for Industry Standards:
Micro800 PLCs support common industrial communication protocols, facilitating integration with other devices and systems within an industrial automation environment.
The Micro800 series combines simplicity, affordability, and flexibility, making it a compelling choice for applications ranging from simple control tasks to machine automation in industries such as manufacturing, automotive, and more. As a solution that balances cost-effectiveness with functionality, Micro800 PLCs provide an accessible entry point for those entering the realm of industrial automation.
