DAQmx Switch Disconnect

Immediately terminates switch connections you created by using the DAQmx Switch Connect VI. This VI returns an error if you attempt to terminate a connection that does not exist. The instances of this polymorphic VI terminate a single connection or multiple connections.

Using this VI on topologies with multiplexers or form C relays does not necessarily imply an electrical disconnect because disconnecting channels in these topologies might connect another channel as a side effect. The DAQmx Switch Disconnect VI frees such channels for use in other connections.

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

Place on the block diagram.

Find on the Functions palette.

Single 

Terminates a connection you specify with the endpoints switch channel 1 and switch channel 2.

	switch channel 1 is the first channel in the connection. A DAQmx switch name constant lists all switch channels available on devices installed in the system.
	switch channel 2 is the second channel in the connection. A DAQmx switch name constant lists all switch channels available on devices installed in the system.
	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. If an error occurs while this VI or function runs, the VI or function 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 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.
	wait for settling specifies whether this VI waits for the switches to settle before returning. If wait for settling is FALSE, the VI returns immediately after the operation. Use the Settling Time property to control the settling time.
	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.

Multiple 

Terminates the connections you specify in disconnection list. This VI can terminate connections on multiple devices. In the event of an error, the VI stops at the point in the list where the error occurred. If you set wait for settling to TRUE, this VI waits only after terminating all connections. If you want to wait for settling between disconnections, use this VI multiple times to terminate connections separately.

	disconnection list uses a special syntax to specify the list of switch connections to terminate.
	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.
