1. Can we reference any dll and call api in ST?
2.Can we debug ST anywhere or just by monitor& watch the output result?
3.Can you plz provide more information about service sequence
4.Can you talk about any difference between 4DIAC and CodeSys?
Thank you very much!

It's my hornor to get reply from you, Mr. Zoitl, i read your book before,very excellent
1.You mean, that i should export the new function block to c++file, import the dll and compile it with forte source code ? That cost too much time and seems a little bit complex. Can we just do this just in 4Diac IDE more efficently?
In codesys, can just reference dll and call api directly in ST language.
2. i didn't see any document or help about debugging ST, such as breakpoint, step over and so on.
3. you mean now service doesn't make sense till now?
4. There are a supported PLC list of device here :https://www.eclipse.org/4diac/en_rte.php
would you plz tell me why some devices are supported and others(siemens, Mitsubishi,omror) are not?

Mr. Zoitl, i'm so glad you give me a so quick response.
I read the news of the student will do some work with Lua totally support, dynamic compling is good, no more exporting *.cpp files and long time compling forte is also good, but i don't think lua will solve the most important things,
such as some global virable, device, object declare and using, dll importing/reference. debugging integrated source code easily, compling that without whole forte sourcecode(that cost long time),
function block is the key point for resuse, but if it is hard to produce and debug, then mean what? That is from my point of view :)

Hi,
thanks for your feedback. Feedback like yours help us to target our future development. However I have to point out that we will definitely not provide global variables. IEC 61499 does not allow global variables and that is good so.
Cheers,
Alois
