Allen-Bradley created the Micro800 Controller series, which is intended for small to medium-sized industrial control applications. A variety of cutting-edge capabilities are available on these controllers to satisfy the needs of contemporary industrial automation. An overview of some of the sophisticated features that Micro800 Controllers typically have is shown below:
1. Embedded Ethernet Port:
An embedded Ethernet port is a feature that many Rockwell Automation Micro800 controllers have, enabling them to communicate with other devices on an industrial network. This provides functionality such as remote monitoring, scripting, and data interchange.
The Micro800 controller can speak with other devices connected to an Ethernet network thanks to the inbuilt Ethernet connection. This involves exchanging data with other PLCs, industrial devices, human-machine interface (HMI) panels, and supervisory systems.
Users can remotely monitor and control the Micro800 controller over a network thanks to its inbuilt Ethernet connector. Applications where there may be limited access to the hardware controller and where remote troubleshooting or modifications are necessary may find this especially helpful.
Programming and configuration chores are facilitated by Ethernet connectivity. Through the Ethernet connection, users can use programming software to adjust the controller's settings, upload and download programs, and make online revisions.
2. Modbus Support:
A popular communication protocol in industrial automation is modbus. Micro800 controllers frequently have Modbus capability, which enables them to exchange data and control with other Modbus-compatible devices.
A group of communication protocols known as Modbus are used to transfer data between electronic equipment. It has Modbus TCP for Ethernet communication and Modbus RTU (Remote Terminal Unit) for serial communication.
Modbus RTU protocol can be used by Micro800 controllers that support Modbus for applications that need serial communication. Usually, RS-232 or RS-485 serial connections are used for this, enabling communication with other Modbus-compatible equipment.
Modbus TCP can be used by Micro800 controllers that have embedded Ethernet ports to communicate via Ethernet networks. This permits communication with a wide range of Modbus TCP-enabled devices, including HMIs, other PLCs, and SCADA systems.
3. Built-in Analog I/O:
There are Micro800controller models with integrated analog inputs and outputs. As a result, extra modules are not required for the controller to process analog signals from sensors and actuators.
Integrated analog I/O Micro800 controllers usually have analog input channels. Analog sensors, transmitters, and other devices that provide continuous voltage or current signals can all have their signals read on these channels. Applications that require the monitoring of variables like temperature, pressure, or flow frequently employ analog inputs.
Micro800 controllers provide analog output channels that enable the creation of analog signals. Devices that accept analog control signals, such as proportional valves, variable frequency drives (VFDs), and other actuators, can be controlled by means of these signals. For applications needing exact process control, analog outputs are essential.

4. Expandable I/O Options:
Generally speaking, expansion modules for digital and analog I/O can be added to micro800controllers. Due to its adaptability, users can tailor the controller to match the unique needs of their particular applications.
The modular nature of Micro800 controllers often enables customers to add I/O modules to expand the system in accordance with the particular needs of their application. Modularity makes it easier to configure and update systems.
By adding digital I/O modules, users can increase a Micro800 controller's digital I/O capacity. Additional input and output points that can be utilized to link actuators, switches, sensors, and other digital devices may be included in these modules.
5. Integrated Motion Control:
Basic motion control features are supported by several Micro800 controllers. Applications requiring precise motion control, such positioning or speed control, can benefit from this.
Motion profiles can be created and carried out thanks to integrated motion control. A motion profile outlines the ideal movement of a motor or actuator over time, including details on acceleration, deceleration, and velocity.
Stepper and servo motors may be supported by Micro800 controllers that have integrated motion control. Stepper motors are typically utilized in open-loop systems when positional accuracy is sufficient, but servo motors are frequently used in applications needing precise control and excellent performance.
6. High-Speed Counter Inputs:
Micro800controllers commonly offer high-speed counter inputs, enabling them to handle applications that need counting and recording high-speed events, such as encoder pulses.
Usually in the form of pulses, high-speed counter inputs are made to handle rapidly changing input signals. They are employed in situations where accurate recording and counting of frequent occurrences is required.
Standard digital input channels are substantially less frequent than the input pulses that high-speed counters can count. In applications like motion control, where quick and precise position or speed tracking is needed, counting speed can be quite important.
7. Web Server Functionality:
With the integrated web server feature of certain Micro800 controllers, users can access diagnostics and controller information through a web browser. This can make monitoring and troubleshooting activities easier.
8. Advanced Programming Languages:
IEC 61131-3 programming languages, which include ladder logic and structured text, are generally supported by micro800controllers. This gives programmers the option to select the language that best fits their needs.
For small to medium-sized industrial applications, Rockwell Automation's Micro800 Controller series provides a range of sophisticated functions. Remember that since my last knowledge update, there may have been improvements and upgrades to the Micro800 series, so for the most up-to-date information, make sure to review the most recent release notes and documentation.
