Communication with VWR balance using LabVIEW and VISA

[Michael.Koppelgaard]

Im trying to connect to VWR balance using visa. Its works just fine in C# but when I try to convert the code to LabVIEW its does not work

The c# setup is:

port= new SerialPort("COM4",9600, Parity.Odd,8);
port.DtrEnable = true;
port.RtsEnable = true;
port.Handshake = Handshake.XOnXOff;

in LabVIEW :

Any suggestions?

Please explain what exactly "does not work"…

I'm noget getting any data from the VISA READ buffer

Any error on the error cluster?

Do you get something if the lenght if 1 instead of 100?

[Michael.Koppelgaard]

No error on the error-cluster. And I can’t explain why but now it works😊

Also show the C# code that actually sends the command, and enable the "Display Style" glyph on the string constant in LabVIEW if you really have to post an image/snippet, or post the VI instead, preferably backsaved to LabVIEW 2018 or similar.
