I want to communicate in PDMM controller via HTTP. Actually I can read from them in C++ but I can't write any value to the variable of PDMM controller in C++. Furthermore I am able to write and read via http with the language of C# by using example codes in KAS IDE software online help , in this there isn't any problem.
The code that I used for reading variables is added with the name of "include.pdf". In this document, I use C++ language, Libcurl library and jsoncpp( as KAS IDE software online help's recommendation).
