How to configure S7-1200/S7-1500 as an MQTT Client with TIA Portal

Check out this video that tells you how to do it!

Check our video on how to set up a Mosquitto broker:

You can find the library and an example project here:

Hello. Congrats for the video. But can you show how to configure everything when using TLS ? like port 8884. I am interested in how to configure certificates in tia portal so the client will work on a plc with the highest security level possible. Thanks

Hi AutomationStation,

I have succesfully setup Mosquitto broker. Now I have this IoT Device(thermal temperature scanner) that when I setup it ask me two things:
1.) Url (I put here the ip address of the mosquitto broker and port).
2.) Company Id (Im not sure what to enter here. Should I enter here the service name of the Mosquitto broker which is mosquitto?)

Im not sure about the no. 2. I still cannot connect the device to mosquitto broker.

I hope you can enlighten me . Thanks a lot for this tutorial.

This video was helpful. Have you worked to send series of data written in a DB(I have sensor values, and other field devices values in the Data blocks) through MQTT instead of just sending messages??

Dear thanks for your video, can you make a video how to send and receive data from s7 1500 plc to aws iot cloud.
Thanks in advance

Good night, all right? Can you make the MQTT block available for download on any platform other than SIEMENS? because now they no longer provide only the block without configurations, it already comes with some. I'm doing TCC and needed it without any configuration, like yours.

Hi, thanks for your video, I am getting status ID error 3, once i enable MQTT data, tcp and mqtt established remains zero, what must be the reason

[nguyenquocthinhtruong]

I see you have HomeAssistant in your Network, can you make a Video, how to use a Siemens PLC together with HomeAssistant?

[demismeetsful]

Hi,
Thanks for the video!
It looks like the lmqtt library for V16 is no longer on the Siemens website. The only options I have is to download the documentation or the example project. Do you know where I can download the library?

[sibaissa]

Hi, thank you for the good videos.
can I publish from the same laptop that I used as a broker? or should the broker and publisher be on separate devices??

[Theredhawk]

I am facing this issue. Can you help me?

The interface of data type LMQTT_Client has been changed.
