Bringing PLC values to OPC UA, MQTT, GraphQL

With just some lines of configuration you can bring PLC values to OPC UA, MQTT and GraphQL. And to a variety of databases for tag logging…

💡 In that example with ModBus, but thanks to #plc4x this should work in the same way also for the other protocols supported by PLC4X.

📺 See the video, ModBus values are brought to OPC UA and MQTT.

💣 In MQTT the topic name is enriched with a UNS ISA95 topic path.

âš¡ On MQTT SparkplugB encoded messages could be used.

😎 100% GUI free and Open Source.

Automation Gateway Video Tutorial

In this tutorial, I will guide you through the essential steps to set up the Automation Gateway, harness the power of YAML extensions in Visual Studio Code for configuration, and connect various devices, including OPC UA, MQTT, and PLC4X devices. I will show how to integrate the values from the devices to the Gateway’s OPC UA server and how to use the MQTT interface to get the values from the devices via a MQTT client. Additionally values from the connected devices will be logged to a Influx database.
