DAQmx Switch Connect

DAQmx - Data Acquisition VIs and Functions

DAQmx Switch Connect

Makes immediate connections between switch channels. The DAQmx Switch Connect VI attempts to find the shortest available path between the channels. If a path is not available, this VI returns an error. The instances of this polymorphic VI make a single connection between two switch channels or make connections between multiple switch channels.

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

Single 

Makes a connection between switch channel 1 and switch channel 2.

civrn.gif 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.
civrn.gif 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.
cerrcodeclst.gif 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.
cbool.gif 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.
ci32.gif 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.
cstr.gif 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.
cbool.gif 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.
ierrcodeclst.gif 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.
ibool.gif status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
ii32.gif 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.
istr.gif 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 

Makes the connections you specify in connection list. You can specify the two endpoints only or the explicit path between the two endpoints. This VI can make connections on multiple devices, but each individual connection must reside on a single device. In the event of an error, connecting stops at the point in the list where the error occurred. If you set wait for settling to TRUE, this VI waits only after making all connections. If you want to wait for settling between connections, use this VI multiple times to make connections separately.

cstr.gif connection list uses a special syntax to list the connections to make between switch channels.
