Hi 4D,

two notes:

-you only provide a buffer of 6 elements, when the doc is talking about 8 elements (don't forget those 2 reserved fields!)

-you provide a buffer of U8 elements, when the doc is talking about "Integer" - please check what "Integer" is referring to!

I cant C+. I dont now, is the ReadData.vi true or false.

I have a 8 Integer.In the Busser are the LSB and the MSB Date.

Channel 1 is 0.

In the original software ist in the ReadDate the channel 1 a data (8 oder other).

Hi 4D,

could you please rephrase your question? I don't understand what you're trying to say...

(Use your native language additionally, I suspect you're a German?)

That's OK, since that's not C++ - it's Pascal. In addition to having the correct array size, and the correct integer type, did you configure the Call Library Function Node to use "stdcall" conventions?
