 The [**open62541** library](https://github.com/open62541/open62541) is an open-source implementation of the **OPC UA** standard. It is lightweight, efficient and written in C, making it ideal for embedded systems like the Opta. The library provides a flexible framework to create **OPC UA** servers and clients, ensuring compatibility with the standard while maintaining high performance.
