25- IoT Masterclass, Part3: Programming a Siemens PLC to Publish/Subscribe to MQTT Topics

In the this new vide (part 3 of IoT Masterclass) we delve into using a Siemens PLC (featuring the 1200 CPU) to publish/subscribe to an MQTT broker on our Raspberry Pi5 test server. This comprehensive guide is tailored to supercharge your IIoT journey with Siemens PLCs!

🔍 Discover key insights on:

Downloading essential MQTT library.
Integrating the library into your TIA Portal project.
Mastering the function block and conducting foolproof tests.
Applying the function block to publish analog input values to the MQTT broker.
Storing PLC analog values in our InfluxDB database and visualizing historical data on the Grafana dashboard!

Stay tuned for Part 4, where we'll elevate our IIoT project by adding a Siemens HMI panel to enrich our MQTT broker data.
