XNET Future Time Trigger
Provides the future timestamp for an exported Time Trigger.
Inputs/Outputs
session in
The session to read.
when
when provides the future timestamp at which the exported Time Trigger terminal will transition from low to high.
timescale
timescale specifies the timescale that is used with the Time Trigger.
The default value is Local Time (0).
| Local Time | 0 | This is the local timescale of the XNET hardware (such as the PXI backplane clock). |
| Network Time | 1 | This is the network timescale (time sync protocol such as IEEE Std 802.11AS). |
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
session out
An output that is the same as session in, provided for use with subsequent nodes.
error out
Error information.
The node produces this output according to standard error behavior.
Description
When you use the XNET Connect Terminals with source terminal of TimeTrigger (i.e., exported), the destination terminal is set low. This XNET Future Time Trigger VI provides a future timestamp for the exported Time Trigger to generate a pulse (low to high followed by high to low).
If you provide a when timestamp that cannot be generated (e.g., in the past, or too soon in the future for XNET to handle), this VI returns an error.
If you invoke the XNET Future Time Trigger VI while a previous invocation of the XNET Future Time Trigger VI is pending, an error is returned; future timestamps are not queued.
An invocation of XNET Future Time Trigger VI is canceled if you disconnect the exported Time Trigger (for example, by using XNET Disconnect Terminals or XNET Close, or by stopping execution of your top-level VI).
