List of supported communication protocols :
https://www.codesys.com/products/codesys-communication.html

You need to choose/ decide which one you want.

note : "Qt Creator" is an IDE. You shoud say "Qt"

@LeLev I did not find Qt in list of supported communication. Is it possible to communicate PLC through TCP protocol in Qt ?

Of course, since Qt is not a communication protocol. It's an application development framework (mostly based in C++) comprising several modules.

In addition to TCP/IP as mentioned previously, from the list of communication methods for that PLC device, Qt also supports OPC UA

Qt also supports OPC UA

+ modbus TCP/RTU.

@Pablo-J-Rogina is this OPC UA in open source version ? or it is in only commercial version ? do i need to install C++SDK ?
