Connect Single

Creates a path between channel 1 and channel 2. NI-SWITCH calculates and uses the shortest path between the two channels. Refer to Setting Source and Configuration Channels for information about channel usage types.

channel 1 specifies one of the channel names of the desired path. Pass the other channel name as channel 2. Refer to Devices for valid channel names for the switch module.

Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp.

error in 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 ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.

/images/reference/en-XX/help/375472H-01/ci32.gif

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.

Connect Multiple

Creates the connections between channels specified in connection list. Specify connections with two endpoints only or the explicit path between two endpoints. NI-SWITCH calculates and uses the shortest path between the channels. Refer to Setting Source and Configuration Channels for information about channel usage types. In the event of an error, connecting stops at the point in the list where the error occurred.
