Configures channels for dynamic acquisition (if instrument handle is an acquisition session) or dynamic generation (if instrument handle is a generation session).

Note A channel cannot simultaneously be assigned to static generation and dynamic generation.

instrument handle identifies your instrument session. instrument handle is obtained from the niHSDIO Init Acquisition Session VI, the niHSDIO Init Generation Session VI, or the niHSDIO Init Ext Cal VI.

channel list specifies which channels are reserved for dynamic operation.

Examples of valid syntax for this control are 0:31 or 0-15,16-31 or 0-30,31. The order of these channels specifies the order when using the waveform data type instances of the niHSDIO Read Waveform and niHSDIO Write Named Waveform VIs.

Leave channel list blank to specify all channels. Use none to unassign all channels.

error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source identifies where 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.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI.

error out contains error information. This output provides standard error out functionality.

	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.
