DO WHILE LOOP

[FlorianJ]

Hello community,

I have a question about a DO WHILE loop. I use the While loop frequently, but now I'm in need of a DO WHILe loop. I want it to run once, then wait for a user input that decides whether to run it again or procede. I'm running a meassurement that ocassionally fails, so I want the opertunity to rerun it bevore I move on to the next step.

I'm sure there is a simple solution, I just don't see it.

Thank you in advance,

Florian

Based on your requirements, I suggest you to use a state machine. You will find plenty of information on this on this forum, the ni web page. You also have a template with your LV installation.

Hi Florian,

attached you´ll find two screenshots/VI snippets of examples, currently I don´t have access to a LV 7.1 installation, but these two are very simple  to reprogram.

1. Acquire the data and thenWiat for the user input. On "Measure again?" you run the loop a second time, on Measurement ok, you leave the outer loop and give your data to wherever you need it.

2.

The smarter way, if you have to wait for a USER reaction, is to use a Event structure for acquiring and stopping the main loop.

Hope that helps.

Florian,

The "while loop" that comes with LabVIEW actually is a "do while loop" since it will defenetly execute atleast once.

Or to say that the "while loop" are actually "do while loops" in LabVIEW.

What you need is some thing like a state machine or events like others mentioned
