What is simple VI and general VI

[GSR]

I see an MCQ, there are two VIs

one is add 2 number together

one is DAQ vi inside a while loop

which one is simple VI

both of them are simple and general<-- that is what I think

This is terminology on design patterns from NI:

Simple VI - block diagram is usually a component/function - typically a subVI

General VI - block diagram contains parts e.g. initialise routine >> main (loop) >> shutdown routine.

Therefore use the above terminology IMHO:

"add 2 numbers" = simple VI

"DAQ vi inside a while loop" = general VI

What is "nested formula node" structure mean?

I see this in the CLAD sample exam, which ask formula node accept which of the following operation

Nested structures refers to placing a NI structure inside a NI structure. An example would be placing a case structure inside a case structure or loop inside a loop. You can not place a formula node inside a formula node, so if the question was which one of the below is not valid "nested formula nodes" would be the answer.
