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.
