task in
task in is the name of the task that the operation applies.
source
source specifies the physical channels to use for pattern matching. The order of the physical channels determines the order of the pattern. If a port is included, the order of the physical channels within the port is in ascending order.
pattern
pattern specifies the digital pattern that must be met for the trigger to occur.
error in
error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.
trigger when
trigger when specifies the condition under which the trigger occurs.
| Name | Description |
|---|---|
| Pattern Does Not Match |
Trigger when the physical channels do not match the specified pattern. |
| Pattern Matches |
Trigger when the physical channels match the specified pattern. |
task out
task out is a reference to the task after this node runs.
error out
error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.
Where This Node Can Run:
Desktop OS: Windows
FPGA: LabVIEW NXG does not support FPGA devices
Web Server: Not supported in VIs that run in a web application
