CLAD LabVIEW Programming Fundamentals 3

Question 1

What is the default behavior of Auto-Indexing on a For Loop output tunnel?

Accepted Answer

Auto-Indexing is enabled by default, accumulating values into an array

Answer

For Loop output tunnels have auto-indexing enabled by default, collecting each iteration's value into an array.

Question 2

Which function correctly initializes a 1D array of 10 zeros in LabVIEW?

Accepted Answer

Initialize Array with element=0 and dimension size=10

Answer

Initialize Array creates an n-dimensional array filled with a specified element value; wiring 0 and 10 creates a 1D array of ten zeros.

Question 3

What color is a string wire in LabVIEW's block diagram?

Accepted Answer

Pink (magenta)

Answer

String data types are represented by pink (magenta) wires on the LabVIEW block diagram.

Question 4

Which terminal type on a SubVI connector pane indicates that an input is required?

Accepted Answer

A terminal that causes the VI to be broken if left unwired

Answer

Required inputs are set in the connector pane editor; leaving them unwired breaks the calling VI, signaling that the input is mandatory.

Question 5

What is the function of the 'Wait Until Next ms Multiple' function compared to 'Wait (ms)'?

Accepted Answer

It synchronizes loop timing to a multiple of the system clock, reducing timing drift over many iterations

Answer

'Wait Until Next ms Multiple' aligns delays to a multiple of the clock tick, preventing accumulated timing drift in loops compared to 'Wait (ms)'.
