Send a Command through MQTT

[rick-pit]

Hi, im configuring MQTT plugin and i can receive data succesfully. My next step is be able to turn ON-OFF something connected thought MQTT subscribe to a specific topic in this case “/output/508”.

I upload pictures of my current configuration:

https://ibb.co/cMZtbb
https://ibb.co/jgCeGb
https://ibb.co/mXi89w
https://ibb.co/bs889w
https://ibb.co/nLd89w
https://ibb.co/jcdVNG
https://ibb.co/cwBjhG

With this i dont have any output in the configured Publish Topic after execute command (i asume this is the expected behaviour, if is not that help me to understand with information about configure a command) The only info i receive through the output channel of the switch (dynamic picture with ON/OFF images) are the same value received through the input channel (i can display the right image after receive value on the input channel). Maybe i missunderstood something but i cant find information about it to make validations of my settings.

Please help me.

Hi,
Thank you for the description.
I’d like to ask you for 1 extra screenshot:
When you send a command there should be a appropriate line in the communication line log: https://ibb.co/mXi89w
Could you scroll the log to the moment of the command and make a screenshot of this page?
You can also find the log files at C:\SCADA\ScadaComm\Log

I recommend to increase timeouts of the device to make communication slower while testing.

Now I’ve opened the source of the MQTT driver and realized that the author hasn’t implemented sending commands.
I created an issue https://github.com/bersim/OpenKPs/issues/6

[rick-pit]

Oh, that explain a lot. Thanks Mikhail

[Mikhail]

The author has implemented commands. See the GitHub issue for details.

[rick-pit]

i see it. thanks for your support too

[rick-pit]

Im using binary and standart acommand and they seems great. But i dont see any output from execute. Im assuming i should receive a const or something similar, maybe its not the way it works (i didnt use others communication line yet), can you help me?

[Mikhail]

I think, it better to ask the author by creating an issue on GitHub.

[rick-pit]

you are right i will

i just want to confirm a expected behaviour in other communication lanes. thanks
