MQTT doesn't require ladder for it to function.
Are you looking for any specific example(s)?
MQTT will be turning on outputs Y0 - Y8 1 Topic per output
@Linuxdept (Customer) Put together example (see attached) of Click using MQTT publish and subscribe to HiveMQ broker.
Note: Specific instructions are in the header and rung comments.
MQTT_Example_C1C2_to_Y1Y2
I am not up to speed on MQTT, so....
In your example you state
"This example both Publishes and Subscribes to the two topics:
CLICK/Data1
CLICK/Data2"
Could another CLICK be the target? Meaning could one CLICK be the actual project and another CLICK be the target, instead of the http: site?
Hi kewakl,
The MQTT network would require a broker. Then all of the clicks could publish and subscribe.
This post may help explain better.

Thanks Garry. That answers my question.
I will have to read/watch your MQTT post content.
I was wanting to keep my hardware away from the internet.
mosquitto.org has some broker downloads.

Kewakl, only if your pub/sub from a online broker would you be on the internet , otherwise use a raspberry PI on your Local network as the Broker.
A windows-based broker called Mosquitto can also be used without the internet.

The above is a post showing the installation of this broker with the BRX.

Yeah, as I mentioned above, I will have to delve into your post's contents.
I do not have the time right now.
