How to access the Custom Data type variable given in Expression edit control To and From LabVIEW

[Loka Prakash]

Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa

Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the

VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),

Channel1: Number and

Channel2: Number

I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.

I would like to know how to get the values of this custom data type to LabVIEW?

Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2

how do i need to set this cluster to the Custom Data type variable in TestStand?

Thanks and Regards

Hi,

TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.

 LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.

 

Hope this helps

Hi,

Thanks for the information..

I actually wanted to know ,

how to access the TestStand custom data type variable given in Expression Edit control (f(x)) on the LabVIEW Front panel

instead of unbundling the container value and using TS_GetProertyValue.vis individually for all the componenets of that custom data type.
