Importing keyence LS9501 DLL fails or just won't work

[B_Hackert]

I'm trying to get my Keyence LS9501 laser measurement unit working in Labview.

Keyence only offers a .dll file for 32Bit and 64Bit, see

https://www.keyence.com/download/download/confirmation/?dlAssetId=AS_58192&dlSeriesId=&dlModelId=&dl...

so I manipulated the header file according to

https://www.ni.com/docs/en-US/bundle/labview/page/calling-external-apis.html

and imported the dll by tools/import/shared library, working fine for the 32Bit version, the 64Bit version offers no function to convert, strange...

So I went on with the 32Bit version, although running on 64Bit Windows 10. I can open the Ethernet connection and get measurement values, but what is most important for me are the set and get settings function, which don't work.

I get error code 1097, Call Library Function Node in LS9_IF.lvlib:LS9IF Get Setting.vi->LS9501.vi and get no value for the settings I want to read in.

The VI created by the wrapper indicates the red informations as a string instead of bytes, also the control for writing the settings is a string instead of bytes.

In the header file of the dll, the control / indicator is defined as BYTE* , can i modify this in any way so the VI will accept byte or at least will indicate the output right, because all I get in the indicator is "".

Hi @B_Hackert,

I know that it is not a direct answer to your question, but after a very brief research I found information about Communications Library from Keyence.

Did you see this forum discussion?
