Hello
I would like to API request by 1518F-4PN/DP PLC  via internet.
On the PLC NTP and DNS is set!

Use LHTTP_GET 2.1.4
hwID=0

With http pages work.Get back the html code to response block of char. So the internet connection is done.

First of all tried with a simple web page 'icanhazdadjoke.com' https://icanhazdadjoke.com/api
url input - 'icanhazdadjoke.com'  respons code:308, status:8403 statenumber:4
url input - 'www.icanhazdadjoke.com'  respons code:301, status:8403 statenumber:4
url input - 'https://icanhazdadjoke.com'  8601 - subfunction status 80E1,80E2,80E4  stateNumber3(T_CON)
Response data is empty all the time.

I tried change TLS input parameters many different way with many certificate but it isnt affect the response.
Server is required TLS V1.3. Does anyone know this block is supports TLS V1.3. And if it yes, how should it set up correctly the functionblock?

I didn't find any documentation which TLS version is supported by the library or the cpu (fw 3.0.3)?

I tried this simple GET request with postman program. And it is work well and easy.
Does anyone idea how it should working?

Split from LHTTP, https web request.

Hello,
Not yet! :( If I find a solution I promise I'll make a YT video. :D

The error codes 80E1, 80E2 and 80E4 all indicate that there is a problem with the TLS encryption. Either you're referencing the wrong certificates or they are missing on the PLC altogether. Can you share a screenshot of the PLC's certificate manager and your parameters at "tls"?

As far as I know SIMATIC controllers only support TLS v1.2 but most webserver accept that.
