DAQmx Create Virtual Channel

Creates a virtual channel or set of virtual channels and adds them to a task. The instances of this polymorphic VI correspond to the I/O type of the channel, such as analog input, digital output, or counter output; the measurement or generation to perform, such as temperature measurement, voltage generation, or event counting; and in some cases, the sensor to use, such as a thermocouple or RTD for temperature measurements.

If you use this VI within a loop without specifying a task in, NI-DAQmx creates a new task in each iteration of the loop. Use the DAQmx Clear Task VI within the loop after you are finished with the task to avoid allocating unnecessary memory. Refer to Task Creation and Destruction for more information about when NI-DAQmx creates tasks and when LabVIEW automatically destroys tasks.

The DAQmx Channel properties include additional channel configuration options.

Use the pull-down menu to select an instance of this VI.

	maximum value specifies in units the maximum value you expect to measure.
	minimum value specifies in units the minimum value you expect to measure.
	custom scale name specifies the name of a custom scale for the channel. If you want the channel to use a custom scale, wire the name of the custom scale to this input and set units to From Custom Scale.
	bridge information specifies information about the bridge configuration and measurement. voltage excitation source specifies the source of excitation. External (10167) Use an excitation source other than the built-in excitation source of the device. If you select this value, you must use the voltage excitation value input to specify the amount of excitation. Internal (10200) Use the built-in excitation source of the device. If you select this value, you must use the voltage excitation value input to specify the amount of excitation. None (10230) Supply no excitation to the channel. voltage excitation value specifies in volts the amount of excitation that the sensor requires. Refer to the sensor documentation to determine this value. lead wire resistance is the amount of resistance in ohms in the lead wires. Ideally, this value is the same for all leads. initial bridge voltage specifies in volts the output voltage of the bridge in the unloaded condition. NI-DAQmx subtracts this value from any measurements before applying scaling equations. Perform a voltage measurement on the bridge with no strain applied to determine this value.
	task out is a reference to the task after this VI runs. The task contains any newly created virtual channels. If you did not wire a value to task in, NI-DAQmx automatically creates the task this output refers to.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
