Now you have your local OPC UA server running!īefore we move to the next step, we still need to gather some information. If you click on the details of these data items, you should see how some data is changing continuously. To start the OPC server, click Tools -> Launch OPC Quick Client. You should see the sample OPC application loaded in your KepServerEx system. Start KEPServerEX Configuration from the Windows Start menu, and click File -> Open to open the OPC Painting Demo.opf file you just downloaded. Then, you can import the sample OPC file, named “ OPC Painting Demo.opf” provided in our sample code from our github repo.

We used the demo version for this tutorial on Windows. In this tutorial, we will show you how to setup a local OPC UA server on your Windows PC to run this tutorial.įirst, you need to download the KEPServerEX.

Configure Node-RED to send data to FRED.

Setup and config an OPC UA server on your Windows PC.

You can do this by installing in “Add or Remove nodes” menu.

You need to install the “dashboard” node on your FRED instance.

You might also want to go through this tutorial about STS-MQTT first. You can refer to the Node-RED installation documentation for more information.

Node-RED installed and running on a Windows PC.

Download and install KEPServerEX and QuickOPC on your Windows.

Access to an OPC UA server, or able to set up a server on a Windows OS.

To follow this tutorial you must have the following: OPC UA extends the highly successful OPC communication protocol, enabling data acquisition and information modeling and communication between the plant floor and the enterprise reliably and securely. It is widely used in industrial automation applications. The OPC Unified Architecture is a secure, open, reliable mechanism for transferring information between servers and clients. You will not be able to log in until you validate your account. Īfter registering, make sure to activate your account via your email. Demo accounts are free and can be used for these tutorials and any other experiments you may have with Node-RED.

If you don’t already have an account on FRED (Cloud Node-RED) set one up now. You can find the sample code for this tutorial here. This tutorial will be focusing on how to send data from a local OPC UA server to FRED using node-red-contrib-opcua, the STS-MQTT platform, and how we can further process the data using FRED. FRED is a Cloud-hosted Node-RED platform that can be used to provide an easy and reliable solution to process and monitor data from your OPC UA server.

It is a sophisticated, scalable and flexible mechanism for establishing secure connections between clients and servers. OPC Unified Architecture (OPC UA) is a popular machine-to-machine communication protocol in industrial automation.
