Hello everyone,

I’m currently working with a **WAGO 750-8112 controller** and would like to **send data to the cloud using the native MQTT protocol**.

Previously, I was using the **WAGOAppCloud library** with the WAGO protocol. However, this approach has some **limitations with the number of cloud tags** that can be used, so I’m exploring a **native MQTT implementation** for more flexibility and scalability.

If anyone has an **example project, configuration guide, or code snippet** showing how to use **native MQTT in CODESYS 3.5** , I’d really appreciate it if you could share or provide some guidance.

Thank You @WagoDamRud for the response. As the above license is not available free of cost, I would like to request an example code demonstrating how to send data to the cloud using the native MQTT protocol.
