How to read a response from io-link device

[jklp]

Hello,

I use inet.fp fonction "INET_IWebBrowser2Navigate" with an URL like "http://192.168.1.213/devicetag/applicationtag/getdata"

to get a json response on a io-link device.

It work but a download windows appear and I must manualy download the file "getdata.json" where I found the good informations inside.

But I want the receive these informations in a string because my application work on a automatic machine.

I try to use many inet callback but every time the callbackdata pointer is NULL.

Is anybody have the same problem or more the solution ?

Thanks in advance.
