An overview of Micro800 PLCs in brief

A line of programmable logic controllers (PLCs) called the Micro800 series was created by Rockwell Automation. These PLCs are from the Allen-Bradley brand, a division of Rockwell Automation, and are intended for small to mid-sized applications. Due to its small size, low cost, and simplicity of use, the Micro800 series is well-suited for a wide range of commercial and industrial automation applications.

The following are some of the main attributes of Micro800 PLCs:

1.Compact Design:

Due to its physical compactness, Allen Bradley Micro820 PLC Systems are appropriate for spaces-constrained applications or those where a smaller form factor is crucial.

Space Efficiency: Micro800 PLCs are made to take up as little room as possible in control panels or other places where they are positioned. This is especially helpful in situations when there is a limited amount of space and a smaller footprint is essential.

Panel Mounting: The small size makes it simple to integrate into cabinets and control panels. This is advantageous in situations where there is limited room for housing control equipment, like in control enclosures or compact machinery.

DIN Rail Mounting: DIN rail installation is a common design feature for Micro800 PLCs. Industrial control equipment is typically mounted on DIN rails, and Micro800 PLCs are ideally suited for this kind of installation due to their small size. It facilitates effective control component organization and makes mounting easier.


These PLCs are an affordable option for minor automation projects since they are frequently more affordable than larger, more sophisticated PLC systems.

  • Affordable Entry Point: It’s well known that Micro800 PLCs offer an affordable way to get started with programmable logic controllers. When compared to larger and more intricate PLC systems, the initial expenditure needed to deploy a Micro800-based control system is frequently less.
  • Economical Hardware: Micro800 PLCs’ hardware is made to be as affordable as possible without sacrificing the capability required for smaller automation projects. Micro800 PLCs are appealing for applications where financial limitations are a factor because of their affordability.
  • Compact Design and Integration: Micro800 PLCs’ small size helps save costs in addition to enhancing their adaptability. The integrated I/O options decrease the need for extra external components, and the smaller form factor frequently results in lower material costs.

3.Integrated I/O:

Integrated input/output (I/O) choices are a common feature of Micro800 PLCs, which makes setup easier and eliminates the need for extra hardware.

  • Built-In I/O Modules: Integrated I/O modules, which allow some input and output points to be directly integrated into the PLC hardware, are a common feature of Micro800 PLCs. This can involve speciality I/O types as well as digital and analog inputs and outputs.
  • Space Efficiency: There is less need for external I/O modules or racks when I/O is integrated directly into the PLC. This makes the design more compact and frees up room in cabinets or control panels.
  • Simplified Wiring: The complexity of wiring is decreased with integrated I/O. The PLC and external I/O modules don’t require as much wiring because some of the I/O points are built right within the PLC. This makes the installation procedure easier and results in a control system that is cleaner and more structured.

4.Embedded Communication Ports:

Human-machine interfaces (HMIs), sensors, and other automation equipment can be easily connected to other devices thanks to the inbuilt communication connections included in many Micro800 series devices.

  • Direct Connectivity: One or more embedded communication interfaces, such as Ethernet or serial (RS-232/RS-485) ports, are commonly included with Micro800 PLCs. Direct communication between a variety of devices, such as sensors, other PLCs, human-machine interfaces (HMIs), and other industrial equipment, is made possible by these ports.
  • Ethernet Communication: Micro800 PLCs frequently have Ethernet connections, which enable industrial Ethernet protocol communication. This is necessary to enable data exchange with other PLCs, enterprise-level systems, supervisory control and data acquisition (SCADA) systems, and broader industrial networks.
  • Serial Communication: There are choices for connecting to equipment or legacy devices that employ serial communication protocols using serial ports, such as RS-232 and RS-485. When integrating outdated equipment into a more recent control system, this can be helpful.

5.Programming Software:

For Micro800 PLCs, Rockwell Automation offers programming software known as Connected Components Workbench (CCW). A user-friendly environment is provided by CCW for PLC programming, configuration, and monitoring.

  • User-Friendly Interface: Because of its user-friendly interface, both novice and seasoned programmers can easily utilize CCW. Users can build, modify, and oversee their PLC programs using the workspace that the software offers.
  • Integrated Development Environment (IDE): Micro800 PLC programming, setup, and troubleshooting tools and features are provided by CCW, which functions as an integrated development environment. A variety of editors and wizards for different programming tasks are included.
  • Online and Offline Programming: Micro800 PLCs can be programmed offline as well as online. Online programming enables real-time adjustments by allowing users to modify the PLC program while it is operating. On the other hand, users can create and test programs using offline programming without having to connect to the PLC itself.


Modular extension options are available on certain Micro800 series models, enabling customers to increase the PLC’s capacity by adding more I/O or communication modules as needed.

  • Application Flexibility: Micro800 PLCs can be used for many different purposes, such as basic control jobs, process control in the food and beverage, automotive, and manufacturing industries, and machine automation.
  • Support for Industry Standards: Common industrial communication protocols are supported by Micro800 PLCs, making it easier to integrate them with other systems and devices in an industrial automation context.

In conclusion

The Micro800 series is a great option for applications ranging from basic control duties to machine automation in industries like manufacturing, automotive, and more because it combines simplicity, cost, and versatility. For individuals stepping into the world of industrial automation, Micro800 PLCs offer an affordable entry point that strikes a balance between functionality and cost-effectiveness.
