Is there a Function Block in Somachine to create a basic HTTP API Post request to a specify URL?
Something like https://www.abc.com//DataApi/NewReading?data=DSTRT|25062019112205|00001|DEND
The processor is question is a M251SESE connected to the internet with LTE router.
Thank you

Hi,
I have not tried to do anything like this - HTTP implementation on a PLC, that is a bit away from where I am a bit more comfortable, but have you had a look at this library,
https://www.schneider-electric.com/en/download/document/EIO0000002803/
and that Example guide:

Perhaps it would be enough to get a TCP connection to get it going in a more simple way...
Besides httpS is a show stopper. Not there yet.
You could consider the MQTT perhaps (soon over TLS, in M262):

Who knows - maybe someone will suggest better idea...
Good luck!

Thank you Kamen
I haven't seem some of the reference material. In the end, what I did was to use a 3rd party Linux based solution running Node Red to read the values from the PLC (Modbus) and handle the http request in Node Red.
MQTT was not an option in this case as the API (with the http Post implementation) was provided by the client. It seem the M262 will open a lot of doors for us in the future - fingers crossed.

I'm sorry, I have a problem, I'm a student and I'm trying to connect M262 PLC to Aveva Insight using only Machine Expert capabilities and I don't understand a little bit if it can be done not via MQTT but via HTTP, if anyone knows can you give me some advice how to do it or a recommendation. Thank you in advance.
