OPC UA with C#, NodeJS, MongoDB and MQTT

In this project, we built a program on .NET so that, as an OPC-UA Client, we can connect to a desired OPC server and search, select and monitor continuously the data and tags we need. Then, by connecting to an MQTT broker, this data can be sent in the JSON format to another server programmed with NodeJS. This server stores data with MongoDB database queries. For implementation and testing, we created a hypothetical project in TIA-WinCC RT Advanced and used its OPC Server to provide different tags.
