Clear indicator during the while loop

Hello guys,
I trying an application very easy to show a number of iteration ( or count by encoder in second time) and show a partial and a total on two indicator.
I would like to reset the indicator and chart when i press a clear button, but the only clean is the chart, while the indicator reset to zero rapidly ( with reinitialize to default value) but keep a memory of the iteration riched at the moment.
What kind of solution you can suggest me? ) I tried to use shift register, case structure but I can't find a solution
Thanks again for your precious help or suggest..

here there is a VI modified
Thank you Systemcrash, good suggest..
I tried to implementing your example( and suggest ) with my application to acquire a counter ( I using an USB 6009 as prototype) ,but I can't reset the counting.
My idea is obtain a partial count and total count.
So when I desire press a button reset or Clear and restart to zero on partial counter indicator while the total must be the number of count acquired.
Thanks again for your precious help..

How can I reset the value of an indicator in a while loop, from another synchronous while loop?

I am running 2 synchronous while loops, one which is keep track of time, and the other is measuring periods. In the while loop that is measuring periods, I have a boolean indicator displaying whether the signal is on or off. My problem is that when the signal is off, the VI I use to measure the periods is waiting for the next signal, and displays the boolean value from the previous period measurement. While this VI is waiting, I want the indicator to display false and not the value from the last iteration of the loop.
I am using LV 5.1 for MAC.

Two things you can try:
In preface to the first, the most common (perhaps ONLY) use of local variables should be in transferring data between parallel loops. This is a matter of discipline, and creates programs that are easier to understand, take less time and memory, and are just plain cleaner. Having said that, to transfer data between loops, use a local variable.
Second solution: Instead of setting the value to false, just hide the indicator in question by using control references (property nodes for prev. version of LabVIEW). Control references are a great way to control items on a dialog or HMI screen.

To count the number of while loops, do you just have to attach a DBL indicator to the little i box in the while loop of the program?

I have just followed an example in a book to count while loops and was just want to make sure I havent missed something simple. My program is attached

Hi Ssteel,
Just some additional observations/tips on your code...
1. I notice that you have a standard stop button going into a "run if true" stop condition of the while loop. In this cercumstance it is common to have the stop condition set as "stop if true". You can change this by right clicking the stop terminal and enabling the "stop if true" property. Obviously, it somewhat depends on your design preferences.
2. If you have any issues with the application, perhaps you notice that it is taking over your processor resources, you should add some execution timing into the while loop. You will find the timing functions in the block diagrams functions palette (programming > timing). The Wait (or "wait until next ms") functions will provide your application with "down time", which means that the processor can execute other tasks.
3. To elaborate what MikeS81 correctly stated, insert an incriment before the numeric indicator as shown below to get the actual number of cycles (i.e. the count terminal of the "while" and "for" loops are 0 indexed). Also note that I have changed the representation of the count to interger (blue). You do not need floating point precion when displaying the inciment count, at a while loop can only execute a "whole number" of times.
I hope this has been useful to you Ssteel.

How to code a parallel 'for loop' and 'while loop' where the while loop cannot terminate until the for loop has finished?? (queues also present)

I've attached a sample VI that I just cannot figure out how to get working the way that I want. I've labeled the some sections with black-on-yellow text boxes for clarity during the description that follows in the next few sentences. Here's what I want:
1) overall -- i'm intend for this to be a subVI that will do data acquisition and write the data to a file. I want it to use a producer/consumer approach. The producer construct is the 'parallel for loop' that runs an exact number of times depending on user input (which will come from the mainVI that is not included). For now I've wired a 1-D array w/ 2 elements as a test case. During the producer loop, the data is acquired and put into a queue to be delt with in the consumer loop (for now, i just add a random number to the queue).
2) the consumer construct is the 'parallel while loop'. It will dequeue elements and write them to a file. I want this to keep running continuously and parallel until two conditions are met.
      i. the for loop has finished execution
      ii. the queue is empty.
   when the conditions are met, the while loop will exit, close the queue, and the subVI will finish. (and return stuff to mainVI that i can deal with on my own)
Here's the problems.
1) in the "parallel for loop" I have a flat sequence structure.. I haven't had time to incorporate some data dependency into these two sequential sections, but basically, I just care that the "inner while loop" condition is met before the data is collected and queued. I think I can do this on my own, but if you have suggestions, I'm interested.
2) I can easily get the outer for and while loops to run sequentially, but I want them to run in parallel. My reasoning for this is that that I anticipate the two tasks taking very different amounts of time. .. basically, I want the while loop to just keep polling the queue to get everything out of it (or I suppose I could somehow use notifiers - suggestions welcome)... the thing is, this loop will probably run faster than the for loop, so just checking to see that the queue is empty will not work... I need to meet the additional condition that nothing else will be placed in the queue - and this condition is met when the for loop is complete. basically, I just can't figure out how to do this.
3) for now, I've placed a simple stop button in the 'parallel while loop', but I must be missing something fundamental here, because the stop button is totally unresponsive. i.e. - when I press it, it stays depressed, and nothing happens.
suggestions are totally welcome!
thanks,

I'd actually like to add a little more, since I thought about it a bit and I'm still not quite certain I understand the sequence of events...

So i read a bit more about the 'dequeue element' function, and as I understand it, since there is no timeout wired to the dequeue element function, it will wait forever, thus the race condition I suggested above can never happen!
Yes, you got it!
As I've thought about it a bit more, there's a few things that surprise me... first, the reason the 'dequeue element while loop' errors is not because there's nothing in the queue, it's becaues the queue has been released and it's trying to access that released queue... However the problem I have is this --- Even though there's no timeout wired to the dequeue element, I still would think that the while loop that contains it would continue to run at whatever pace it wanted -- and as i said before.. most of the time, it would find that there is nothing to dequeue, but once in a while, something is there. however, it seems that this loop only runs when something has been enqueued. the reason I say this is illustrated in the next code sample MODv2 that's attached below. I've added a stop button to the "queue size while loop" so the program runs until that is pressed. I've also added a simple conditional in the "dequeue while loop" that generates a random number if it a button is pressed... but this button is totally non-responsive... which means to me that the "dequeue while loop" isn't actually continuously running, but only when an element is added to the queue. this still seems almost like the 'dequeue while loop" waits for a notifier from the queue telling it to run. can you explain this to me? because it is different from what I expect to be happening.

How to get the loop sequence time (i) out of the while loop in the sub-vi to the main vi?

I tried to search for the answer but no much luck. My situation is that I used a sub-vi containing a while loop in my main vi. Now I need to see the while loop sequence number (i) from that sub-vi in my main vi. In the sub-vi I have the indicator to show this loop sequence flawlessly, but that's inside the loop itself. If I use this indicator as a terminal in the sub-vi, I can only see the last sequence number in the main vi after the loop finished its execution.
Is there a way to accomplish this? Thanks.

Hi nobody,
well easiest (but error prone) way is to use globals to move data from subvi to main vi. You can also give the reference of the main vi indicator to the subvi to write to a "value" property node. You can also use queues, and there are other techniques too

What happens to the while loop iteration counter if it runs unchecked?

I want to use the iteration counter to initialise a value on the first loop of a while statement. ie i = 0, x = 100. Fine. The application I am building will be left to run for weeks or months on end without stopping (hopefully :¬)). What happens to the iteration counter in this situation? Does it reset to 0 or what? I don't want it reinitialising any values while the loop is running other than when it starts.
I set up a while loop to try to figure out what happens and the iteration counter stops at 2147483648 which is 2^31 - 1.
Any help would be appreciated,
Thanks,
Niel.

It might be something you already looked at, but perhaps it's an option to perform the initialization outside (before) the while loop. That way it will be initialized correctly only once, no matter what the iteration counter does.
Of course if you need the counter for other purposes than initialization you might have the same problem...
Note that a lot of the timer functions also overflow after a certain time (I believe 24 or 48 days?) so be careful running very long loops (but you already knew that probably).

Can we place Analog in Read(AI-READ) Vi inside the while loop for high sample rate like 22ks/s?

I am using E-series Card for data acquisition.My requirement is to sample the channel, and check the 10 samples for certain condition.both at a time.What should be done can we place the AI-READ vi inside for or while loop for this purpose?

Hello,
Yes, you can include the AI Read.vi inside the while loop, you would just need to specify the number of scans to read for every iteration of the loop. Then, after AI Read.vi has read the data, you can do what ever kind of manipulation of the data you would like, before the next iteration of the loop. The one thing to watch out for is what ever manipulation of the data you do, be sure that it doesn't take to long whereas the buffer holding the data starts to back up. That can be checked by looking at the scan backlog output of the AI Read.vi, which will tell you how many scans have been acquired but haven't been read into your program.
Hope this helps!

Using a DAQ value in a location outside of the While Loop it is placed in

I am writing a program that records the speed of a car and then is supposed repeat the action through the use of an actuator. I was able to write the program to the point where I am saving the data into a .txt file and will be able to read it back out. My problem is that I need to use a dbl value that I am calculating from the output of a DAQ Assistant block that is contained inside a while loop in another part of the program to compare current speed vs. recorded speed then output an action. Everytime I try to draw a connection outside of the while loop, the actual value is not read outside of the loop. I cannot put the other part of the program into the while loop because the while loop only performs every .1 to 1 second and I need the output to the actuator to be a continous string delievered to the serial port. I also cannot create another DAQ Assistant block that reads the same port outside of the while loop. I have thought about using a jumper to another input on the input card, but I would prefer not to use the extra space.
So generally speaking, I'm wondering if there is a way to read a value obtained from a DAQ Assistant block outside of the while loop it is contained in.
Thanks to anyone that can help!!!
Travis

Cheers,
I am not 100% sure what your problem is but how about writing the red value into the local variable and reading it outside of the loop? Or enqueue the value into the queue and dequeue it in the other loop (Producer/Consumer Structure (Data))?

How do I store 4 hours of data and get it out of the "while loop" into a spreadsheet file for documenting purposes? "See additional Text for additonal info"

What a have is a VI that uses the following SUbvi's, starts with FP OpenVI, then FP Create TagVI, into a "While Loop" which contains a FP ReadVI outputting data into a Index ArrayVI outputting to a Display (DBL). This shows the output of a FP-AI-100 monitoring a 9v battery. I have to monitor this battery for a 4 hour period my problem is storing the 4 hours of data and getting it out of the "while loop" into a "Write to Spreadsheet File VI" all I seem to accomplish is just one data sample which I get into a spreed ship file with no problem. I just can't get 4 hours worth. By the way this is my first VI and I'm self

How come my local variable is not updating it's value with respect to what's happening in the while loop?

Hello,
I am trying to extract data out of a while loop as my declarations update with respect to the iteration number. I have attempted to use both local variables and shift registers, but with no luck.
I have also done the following example: http://www.ni.com/white-paper/7585/en and it works like a charm.
I attached the PNG file with local variable declaration circled in red. Will attach a VI in the next respnose.
Thanks

OK, looking at the code...
Can you explain what it is supposed to do? What's the purpose of the value property node read which only seems to update an indicator.
The inner while loop should proably be a FOR loop, because the number of iterations is known before the loop starts.
Your use of formula nodes seems overly complicated.

How can i get the while loop to enter a different loop beside the first one

I can't seem to figure out how to change the value to enter into one of the other while statements in the script. I am new to this and can't seem to find anything how to enter in the information to be able to go to different while statements and then run
what is located in that statement.
The script is supposed to let me choose between TC, MonsterLock, and Cyc and then jump to the while statement that is associated with one of them and then run what ever is located in that block. All i am getting is a infinite loop and it never sees the other
while loops. I have 3 set up the go along with the first statement but no matter what i type in for them it always looks at the first while statement and stays there.
Can someone please help me with having it do what i stated earlier.

OK, so you've got a reasonable input loop early on:
write-host "This script sets up DATABASE Staging"
$ProductionDistro = Read-Host -Prompt "Which production do you `enter code here`want to run?(TC/MonsterLock/Cyc)"
While($ProductionDistro -notmatch "^(TC|MonsterLock|Cyc)$"){
write-host "You have entered an error" -ForegroundColor Red
write-host "You must type TC or MonsterLock or Cyc"
write-host "you typed $ProductionDistro"
write-host "This script sets up DATABASE Staging"
$ProductionDistro = Read-Host -Prompt "Which production do you `enter code here`want to run?(TC/MonsterLock/Cyc)"
I've only added two things to that code: a ^ and $ at the beginning and end of your regex pattern. As originally written, it would have successfully matched any string containing TC, MonsterLock or Cyc (such as "bogusTCwhatever", etc).
Now, instead of a bunch of extra While loops based on $ProductionDistro, what you need is some conditionals (either a Switch statement, or some If/ElseIf). For example:
switch ($ProductionDistro)
'TC'
# Do TC Stuff
break
'MonsterLock'
# Do MonsterLock Stuff
break
'Cyc'
# Do Cyc stuff
break

How can I opearate indicator outside while loop?

I do small program, I have many while loops and I want to connect wire (in my application) from each loop to AND gate then to another while loop, but how can I operate these wires to agree with the change of my application inside while loops.
If not clear :
In another words, suppose I want to operate indicator ouside the while loop. How can I operate indicator outside while loop, so when my application become TRUE (inside while loop) the indicator will be ON (outside while loop) and when my application become FALSE(inside while loop) the indicator will be OFF (outside while loop).
Help me if you have any idea please..........................

Hi Rammo,
For the wire to carry the boolean condition from the while loop to an 'and' gate outside, the while loop must stop running
If you want the while loop to keep on running and still pass a boolean value to a destination outside the while loop, use any one of these: property nodes, global or local variables.
i am still not clear as to what you intend to say by this sentence
" I want the wire that comes out from the while loop will become TRUE if it in my application is TRUE inside while loop and the opposite is true. Because I want to connect the wire that comes out from while loop to AND gate than to another application"
plz tell me if the first part of this mail of mine answers your doubt or do you need more information?
regards
Dev
