In industrial automation, programmable logic controllers, or PLCs, are often utilized. The Micro800 series of PLCs from Allen-Bradley is designed for small to medium-sized applications. Micro800 PLCs may be integrated with SCADA (Supervisory Control and Data collecting) systems to provide centralized monitoring, control, and data collecting. The general procedures below can be used to link Micro800 PLCs with SCADA systems:


1. Choose a SCADA Software:


  • Select a SCADA application that is compatible with Rockwell Automation Micro800 PLCs. Popular options include Wonderware InTouch, Ignition, and Inductive Automation. Verify that the SCADA software you choose is compatible with the communication protocols used by PLCs in the Micro800 series.
  • A range of SCADA and HMI (Human Machine Interface) solutions are offered by Wonderware.
  • In addition to functions like historical data tracking, alarms, and reporting, it supports a number of communication protocols.
  • Wonderware is well-known in the industry for its broad use and user-friendly interface.
  • One of the industrial automation software suites from Rockwell Automation is Factory Talk View.
  • It works well with Micro800 PLCs and other Allen-Bradley controllers.
  • It has capabilities including trending, alerting, and graphic displays.


2. Communication Protocols


EtherNet/IP, DF1, Modbus, and other communication protocols are often supported by Micro800 PLCs. Verify the communication protocol that the selected SCADA software and the Micro800 PLCs support. For Allen-Bradley equipment, the typical protocol is etherNet/IP.


  • A well-liked open-source communication protocol for industrial automation is called Modbus.
  • An expansion of the Modbus protocol, Modbus TCP/IP runs via Ethernet.
  • Allen-Bradley created the proprietary serial communication protocol known as DF1 to facilitate communication between PLCs and other devices.
  • Although it's frequently used for serial connection, Ethernet-based protocols are generally preferred by newer systems for quicker and more reliable communication.


3.Set Up Communication in Micro800:


On the Micro800 PLC, configure the communication settings. Configuring the IP address, subnet mask, communication protocol, and other pertinent settings may fall under this category. Usually, the Micro800 series programming software is used for this.


  • Find the "Controller Organizer" in the project tree, then click on the Micro800 PLC that has to be configured.
  • Select the "Communication" tab or a comparable area in the properties window to adjust communication settings.
  • Select the communication protocol supported by your SCADA system. EtherNet/IP and Modbus are popular options, based on your needs.
  • Indicate the required information, including the IP address, subnet mask, gateway, and any other pertinent characteristics.

4.Define Tags and Variables


In the Micro800 PLC, define the variables or tags that you wish to control or monitor. The information that will be shared between the PLC and the SCADA system is represented by these tags.

  • Input Tags: Represent inputs from sensors or external devices.
  • Output Tags: Represent outputs to actuators or other devices.
  • Internal Tags: used for control logic, temporary values, or internal storage.
  • Counter Tags: Represent counters used for counting events.


5.Configure SCADA System


To connect to the Micro800 PLC, set up the communication parameters in the SCADA program. This include defining the IP address, communication protocol, PLC type, and other pertinent information.


  • Open the SCADA application and start a fresh project. Indicate the project's parameters, including its name, location, and any other pertinent information.
  • Based on the capabilities of the PLC, select the proper communication protocol (e.g., EtherNet/IP, Modbus).
  • Indicate the IP address of the PLC along with further communication details.
  • Include graphical components for the process, such as meters, pumps, valves, tanks, and other parts.
  • In order to see data in real time, link the graphical elements to the defined tags.


6.Create Graphics and Screens


Create the SCADA software's graphical user interface to see the data from the Micro800 PLC. Based on the specified tags and variables, create displays, trends, and alerts.


Developing a thorough and intuitive interface that displays the current state of the machinery, procedures, and variables is the aim. Tanks, valves, pumps, meters, and other components are graphically shown; frequently, dynamic animations are used to show changes in condition or value. The connected Micro800 PLC's tags and variables are coupled to these graphical components, creating a smooth relationship between the digital interface and the physical operations.


7.Security Considerations


Put security measures in place to safeguard the Micro800 PLC and SCADA system's connectivity. This might entail applying user authentication, utilizing secure communication methods, and configuring firewalls.


Micro800 PLCs and SCADA systems work together to provide a comprehensive industrial automation solution by enabling real-time data processing, control, and monitoring. Compatibility, communication protocols, security, and scale must all be carefully considered to ensure a successful integration process.
