How to get data from an 'Electronics unit' to LabVIEW with ActiveX ?

[JeanCastre]

Hi,

I have to make an automatisation of a surface tension measure. I'll explain better after this list of what I have to make this work :

-LabVIEW

-A Kibron G2 (measures the surface tension)

-An 'Electronics unit' (bring together the data from the different sensors/motors)

-The software 'DeltaGraphX 3.56' which is sold with the Kibron G2

the Kibron G2

the Electronics unit

Right now I'm able to get the tension corresponding to the surface tension only in the DeltaGraphX software like below.

So I would like these data to appear in indicators in my LabVIEW VI.

I need to bring this data into LabVIEW with the help of ActiveX but I'm only getting errors in the indicators like '-7' or '-9' as below.

I do not have any indication on what -9 or -7 or 0 could mean...

Don't hesitate to ask questions if I wans't clear enough.

Thanks,

Loïc

I would use their software to make sure that your set-up is functioning properly before doing anything with LabVIEW + ActiveX.

A few thoughts. We don’t have the hardware, not even the software or the Programmers Reference manual to that software. Without these things it’s even less than guessing what you need to do. The only people who really can help you here is the technical support from Kibron. You contacted them, right?

The -9 or -7 return value from the GetData method is an error value. What it means should be documented in the Programmers Reference manual. You got that manual? If not that’s the first thing you should ask Kibron about.

Most likely before you can run the GetData method you probably have to run at least one other method such as Initialize, OpenDevice or similar once.

Hi, thanks for your answer. I actually tested two versions of their sofftware, it works properly, I can read data on the two versions but the problem is I don't have the proper activeX to get these data into LabVIEW.
