Standard Connections
Certain connections are common to the majority of VIs. These “standard connections”
include:
Acquisition Number
Device Name
Error In and Out
Standard Connections
Acquisition Number : This connection exists as an input and output on nearly all VIs. It
is used to keep all the parts of an individual acquisition grouped together. Multiple
acquisitions are, in general, only used when you have multiple main devices running at
different acquisition rates triggered to scan at the same time. See Howto #11 for an
example of multiple acquisitions.
Device Name : This connection is used to tie different sections of a device to its
functions. There are certain VIs that have the Device Name and Device Name Out
connections available, although they are not utilized within the VI itself. The purpose of
these ‘pass through’ connections is to make wiring easier and keep the VI diagram clean
looking.
Error In and Out : Error In and Out connections are utilized to keep certain code from
executing, or to force the execution of code under certain circumstances. To avoid hard
failures and un-initialized configuration problems, it is highly recommended that the
Error In and Error Out ALWAYS be connected between applicable VIs.
