Instrument I/O VIs and Functions
Use the TestStand Instrument I/O VIs and functions to share instrument sessions among VIs and other code modules.
The VIs and functions on this palette return general LabVIEW error codes .
| Palette Object | Description |
|---|---|
| Refnum to Session | Returns the underlying viSession handle from a LabVIEW IVI or VISA refnum. You can use the viSession handle in an environment other than LabVIEW. |
| Session Manager - Get Instrument Session | Returns an ActiveX session object that represents the connection to the instrument driver or I/O resource for the logical name Session Name . Instrument session objects are named ActiveX objects that enable software modules to easily share instrument driver instances or instrument connection handles. If a session object already exists for the logical name, the VI returns a reference to it. Otherwise, the VI creates and returns a new session object. |
| Session to Refnum | Converts a viSession handle from an environment other than LabVIEW into a LabVIEW IVI or VISA refnum. |
