Okay, so my goal is to connect some DIOs with the cloud over the MQTT protocol. So if you have any ideas for this. Which PLC can give me this option? I am looking for a less expensive solution between 100$ to 200$.

Some of my friends told me it is available in Micro820. But I didn't get any success.

 

I’ve used PLCs to connect to Azure and AWS with MQTT before, and the Micro820 worked pretty well for me. Setting up the MQTT client and getting the broker settings right took a bit of time, but once I had the security certificates in place, it connected smoothly.

 

You’ll need to configure the MQTT client on the Micro820 and set up the right broker settings to connect to Azure or AWS IoT. Just make sure your security certificates and keys are properly configured to establish the connection.
If you're looking to sharpen your skills in integrating cloud technologies with PLCs, you might want to look into Microsoft Applied Skills. Basically, they offer practical courses that focus on real-world applications, which could be helpful when dealing with cloud and IoT setups like this.

 

To use MQTT with the Micro820, you would need to integrate it with an additional MQTT gateway or use an edge device like Node-RED running on a Raspberry Pi or an industrial PC to handle MQTT communication.

 

Automation Direct Click+ can do this.
