XNET Read (State » Time » Current) (G Dataflow)

Last Modified: February 22, 2017

Reads the current interface timestamp using an XNET session.


session in

The session to read. This session is selected from the LabVIEW project or returned from XNET Create Session.


error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error


session out

An output that is the same as session in, provided for use with subsequent nodes.


time current

An output that returns the current interface timestamp as a LabVIEW absolute time. If the interface is not started when XNET Read (State Time Current) is called, time current returns an invalid time (0).


error out

Error information. The node produces this output according to standard error behavior.


You can use XNET Read (State Time Current) with any XNET session mode. Because the time is associated with the interface, it can apply to multiple sessions.

XNET Read (State Time Current) returns time as a LabVIEW absolute timestamp data type. The timestamp represents absolute time that the interface timebase source drives. You use the timebase source to timestamp frames the interface receives. For a CAN interface, you use the timebase source to schedule cyclic frame transmit.

The interface timebase source is not necessarily connected to the LabVIEW CPU clock, so this timestamp can drift relative to the LabVIEW time used for internally sourced timed loops and LabVIEW Get Date/Time in Seconds.

For more information about the interface timebase source, refer to XNET Connect Terminals.
