Device I/O Name
Within , the term device refers to your NI hardware product, such as a PXI module or PCI card, and the Device I/O name exposes these devices. Each device contains one or more interfaces (ports) to communicate on a network.
User Interface
The Device I/O name is not intended for use on VI front panels or as a diagram constant. This I/O name class is returned as the value of the following properties:
- XNET System property Devices
- XNET Interface property Device
The value these properties return is used as a refnum only.
String Use
determines the XNET Device I/O name string syntax internally. This syntax may change in future versions, so string display or formation is not recommended.
Refnum Use
You can use the Device I/O name refnum as a device node. The XNET Device property node provides information such as the serial number and list of interfaces contained within the device.
LabVIEW closes the device automatically. This occurs when the last top-level VI using the device goes idle (aborted or stops executing).
