cluster to IO session conversion...not possible?

[david_jenkinson]

We want convert IMAQdx IOsession cluster data to an IOsession type in labview, because the IMAQdx IOsession cluster data itself is actually stored in teststand. We having trouble taking the elements of the IOsession and converting them back to the IOsession type that labview can understand and use with the new IMAQdx vision tools. I have attached an example vi which gives the error we are seeing. Yes we have posted a similar thread on the teststand forum, but this seems to be a problem with labview not being able to convert to an IMAQdx IOsession data type, so we are posting this here also. Is it possible to convert the elements of an IMAQdx IOsession (string, unsigned 32-bit int) to an IOsession data type?

BTW, we realize you can pass the iosession data directly to/from teststand by means of the specify module, but we need to access the IOsession data by sequence context because we are passing the data to a subpanel, which only has sequence context being passed in.

david_jenkinson,

    I may be confused as to what you are asking.  The session datatypes are used to keep track of a session with a certain instrument.  The IMAQdx IOsession data clusters will always only work with IMAQdx IOsessions.  When you say convert to an IOsession type in LabVIEW what do you mean?  There are many IOsession types in LabVIEW depending on what you're communicating with, including the IMAQdx IOsession type.

    Perhaps a description of your program would help and the kinds of information you're passing between LabVIEW and TestStand.  Thank you.
