AIChannelCollection.CreateChargeChannel Method (String, String, AITerminalConfiguration, Double, Double, AIChargeUnits)
Creates an AIChannel to measure acceleration using a charge-based sensor. This method adds one or more physical channels to the AIChannelCollection.

Namespace:  NationalInstruments.DAQmx
Assembly:  NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302

Syntax

public AIChannel CreateChargeChannel(
	string physicalChannelName,
	string nameToAssignChannel,
	AITerminalConfiguration terminalConfiguration,
	double minimumValue,
	double maximumValue,
	AIChargeUnits units
)
Public Function CreateChargeChannel ( 
	physicalChannelName As String,
	nameToAssignChannel As String,
	terminalConfiguration As AITerminalConfiguration,
	minimumValue As Double,
	maximumValue As Double,
	units As AIChargeUnits
) As AIChannel

Parameters

physicalChannelName
Type: SystemString
The names of the physical channels to use to create virtual channels. You can specify a list or range of physical channels.
nameToAssignChannel
Type: SystemString
The name(s) to assign to the created virtual channel(s). If you do not specify a name, NI-DAQmx uses the physical channel name as the virtual channel name. If you specify your own names for nameToAssignToChannel, you must use the names when you refer to these channels in other NI-DAQmx methods.
terminalConfiguration
Type: NationalInstruments.DAQmxAITerminalConfiguration
The input TerminalConfigurationTypes for the channel.
minimumValue
Type: SystemDouble
The minimum value, in units, that you expect to measure.
maximumValue
Type: SystemDouble
The maximum value, in units, that you expect to measure.
units
Type: NationalInstruments.DAQmxAIChargeUnits
The units to use to return acceleration measurements from the channel.

Return Value

Type: AIChannel
The newly created AIChannel.

Exceptions

ExceptionCondition
DaqExceptionThe NI-DAQmx driver returned an error.

Remarks

This method creates a local virtual channel for every physical channel name you specify. If you create multiple local virtual channels with one call to this method, you can specify a comma-delimited list of names for nameToAssignChannel. If you provide fewer local virtual channel names in nameToAssignChannel than you create, NI-DAQmx automatically assigns names to the local virtual channels.

If you do not provide a value for nameToAssignChannel, NI-DAQmx uses the physicalChannelName as the local virtual channel name. If you use nameToAssignChannel to create a name for the local virtual channel, you must use this name in other properties and methods.

The NI-DAQmx driver does not determine if the requested settings are possible until the task is verified. CreateAccelerometerChannel(String, String, AITerminalConfiguration, Double, Double, Double, AIAccelerometerSensitivityUnits, AIExcitationSource, Double, AIAccelerationUnits) does not throw an exception for parameter values that are not compatible with your hardware or other settings in your task. To determine if all of the settings for a Task are valid, you must verify the task by starting the task, either with Start or by reading from or writing to the task, or by calling Control(TaskAction) with Verify.
