Hi forum,

I have a PLC as MQTT client whose data needs to be sent on (server)cloud.So I am planning of using Adafruit IO -cloud service.
I have seen post of creatingfeeds/topic(url =https://learn.adafruit.com/adafruit-io-basics-feeds ) and how to create dashboards(url =https://learn.adafruit.com/adafruit-io-basics-dashboards).
Here I dont understand how do I connect my MQTT client to adafruit IO.Can anyone share an relevant example or something similar on how to connect your PLC to adafruit
would be helpful.

Hi Kim1810,

While we don't have any specific documentation about using Adafruit IO with a PLC as a MQTT client, I suggest taking a look at the Adafruit IO MQTT API documentation available here: https://io.adafruit.com/api/docs/mqtt.h ... o-mqtt-api


Here I dont understand how do I connect my MQTT client to adafruit IO.

For information about connecting to the MQTT server, check this page: https://io.adafruit.com/api/docs/mqtt.h ... on-details
