niSwitch Configure Scan List

Configures the scan list and scan mode used for scanning.

Refer to Devices to determine if the switch module supports scanning.

The scan list is comprised of a list of channel connections separated by semicolons. For example, the following scan list will scan the first three channels of a multiplexer:

com0->ch0; com0->ch1; com0->ch2;

Refer to Scan Lists for more information on scan list syntax.

To see the status of the scan, call either niSwitch Switch Is Scanning? or niSwitch Wait For Scan Complete. Use niSwitch Configure Scan Trigger and niSwitch Initiate Scan to configure the scan trigger and start scan respectively.

	instrument handle identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize.
	scan list specifies the scan list to use. NI-SWITCH uses this value to set the Scan List property.
	scan mode specifies how the switch module breaks existing connections when scanning. NI-SWITCH uses this value to set the Scan Mode property. Refer to scan modes for more information. The default value is Break Before Make.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	instrument handle out identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize and used for all subsequent NI-SWITCH calls.
	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, it 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 non-zero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
