Creates a timing source that sends ticks to a Timed Loop on rising or falling edges of a digital signal.
NI-DAQmx uses the counter you specify to detect the edges of the digital signal. Use this node to base a timing source on an external digital signal, or on an internal digital signal, not included in the instance of the DAQmx Create Timing Source node.
source specifies the terminal to which you connect the digital signal you want to use for the timing source. A DAQmx terminal constant lists all terminals available on devices installed in the system. You also can specify a source terminal by wiring a string that contains a terminal name.
counter specifies the name of the counter to use for the timing source. The DAQmx physical channel constant lists all physical channels, including counters, for devices installed in the system.
You also can wire a string that contains a name of a counter to this input.
edge specifies on which edges of the digital signal you want to send ticks to the Timed Loop.
Send ticks on falling edges.
Send ticks on rising edges.
error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.
timing source name is the name to assign to the timing source this node creates.
edge count specifies the number of edges of the digital signal that must occur for the timing source to send a tick to the Timed Loop. For example, if you set this value to 3, the timing source sends a tick to the Timed Loop on every third edge of the digital signal.
timing source out is the name of the timing source this node creates. Wire this output to the source input of the Input Node of a Timed Loop.
If you specified a name for the timing source in the timing source name input, this output contains the same name. If you did not specify a name for the timing source, NI-DAQmx creates a name and sets this output to that name.
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
