Hi Youssef. Yes you can do it with new Unified Comfor Panels. If you use an Ololder HMI which doesn't support Edge apps, you can imolement the data interaction in your PLC and show them on your HMI. Our previous video (Part 3 of IoT masterclass) shows how to connect a PLC to a MQTT broker.
@@blociot yes, I did that, but if I publish from the PLC then the subscribe topic is overwritten directly and the topic is shown by publichen in subscribe

this is exactly what i was looking for.
@@vigigamehacker123 glad you found it useful 🙏
Can you try reading and writing the PLC's variables using MQTT and visualizing them in Node Red Dashboard ? Thank you

But how can I subscribe or Publish to more then one Topic? As a Dashboard i want to visualize the Variables on the Node-red Dashboard
@@YoussefBachiri you just need to copy and paste the set of nodes that I showed to subscribe to the example tag.
