task in
task in is the name of the task that the operation applies.
error in
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
timeout
timeout specifies the amount of time in seconds to wait for samples to become available. If the time elapses, the node returns an error and any samples read before the timeout elapsed. The default timeout is 10 seconds. If you set timeout to -1, the node waits indefinitely.
If you set timeout to 0, the node tries once to read the requested samples and returns an error if it is unable to.
task out
task out is a reference to the task after this node runs.
error out
error out contains error information. This output provides standard error out functionality.
frequency
frequency is the pulse frequency.
duty cycle
duty cycle is the pulse high time divided by the pulse period.
