Regarding the integration of Qt App to WincCC OA

Pradeep Kumar

As u said u have tried WinnCC OA, can u please tell me having a query.

We need to provide a lib and rename it to .ewo extension,
In Qt do we need to create as Qt plugin or Qt shared library?.

As far as I know its a shared library. DLL.

I used a much older version (5) and it was just normal DLLS that could be used by the siemens runtime.
You just created a normal DLL in VIsual Studio and linked with the siemens ODK.
I guess it still the same but i have not seen TigerPortal or what the new stuff is called.

Hi

k do we need to compile through Visual Studio or Qt Creator?.
And when we get .dll we have to rename to .ewo For Ex: MyApp.ewo

Thanks,

Hi.
I think only visual studio is supported. ( the compiler)
And make sure is the right version.
If it wants 2013, then 2015 wont work.

Also Qt Creator is an editor.
And it can use the visual studio - compiler.

so you must use visual studio compiler.
either in Creator or the visual Studio editor.

But you should just ask them. siemens is very expensive and
closed. But they have good support.

K thanks for the reply.

We need to use Qt IDE with Visual studio compiler, for development and implementation.
And As WinCC OA says we need to use Visual Studio 2013 and Qt 5.5.0 version.

Thanks,

Yes, i think mingw is not supported at all.
Also if ODK says VS2013- SP2. Then nothing else will work. So also check service pack level.
( in my little siemens experience)

What is this?

Hi
For the visual compiler.
There comes big updates called Service Packs (SP)
So if docs says
VS 2013 - sp2
it means vs 2013 and big patches sp1 +sp2 also installed.

Sometimes, this is critical.

Pradeep Kumar

The doc says

Visual C++ / Visual Studio 2013 (VC12) Compiler Version 18.00.30501 for x64

is required.
