• For loop runs with the value of N unwired

  In this case will be a loop run connected to the loop N worthless? I have seen a few examples of the loop for run without a certain number of times set to be ran wired or for example a size of table or something like that.

  PauldePaor wrote:

  Here's a program I am and as you can see the image that the program runs without the loop N being wired. The program will run without problem

  As everyone else has said, you don't have to plug something on N.  If you wire up a table for loop for input "auto-index", the loop for will run automatically the smaller table size.

  Perhaps an example will help:

  

  This makes a loop on my table size (in this case, long of 5 elements).  On the edge of the loop for which resembles [] brackets, indicates that it is auto-indexé.  The loop should go through each item one at a time (1, then 2, then 3, then 4, then 5).

• trouble with inner for loop in my procedure values

  Inside of the loop will retrieve values of v_qty for each iteration of the loop outside when he runs the only select the following:
  
  Select nvl (i.total_quantity, i.actual_quantity) in the v_qty of sales_info;
  
  and therefore loses the previously calculated values of v_qty and rem_qty
  in the previous iteration of the loop outside whereas I want inside the loop iterate on it previously calculated the values of v_qty and rem_qty but can not think of a work around.

• How to ensure that the value of a control (for example double) initializes the last value when the VI has been closed?

  I use a cluster as a control. I would like to double in this control to automoatically values to fill their last values set when the VI is opened or accessed for the first time. It would be great if someone could point out for me. Thanks in advance!

  In my opinion, the configuration files are the easiest method and the best.  Simply save your last values to the file when your code ends.  At the beginning of your code, to read the file and fill in the controls with the values read.  With the configuration files, the section name can be the name of the cluster, and key names can be control names.

  I know OpenG has some pretty nice to do, but I prefer to use the native functions OR when I can.  When porting to a new system, there is no need to copy any additional screws library (OpenG library).  The native DV come with Labview.

  Hi, Seb,

  Yesterday, knowing very little about your needs, I said it sounded as if utl_file was the best way to get the desired results.
  Today, a little more about what you want, I can say without a doubt that this utl_file is the best way to get the desired results. You're actually disable features (such as headers and column of packaging) that could be helpful to use the COIL. Use utl_file and save a lot of time for you now, and for those who must maintain the code in the future.

  If you want to help with the approach of SQL to SQL, after a test case complete (including CREATE TABLE and INSERT statements to recreate some of the data. Simplify the problem as much as possible, so that you still get the same error, with a minimum of code.
  It would be useful to post a copy of your script generated dynamicaly, weekly_all_clients.sql, which causes the error.

  Do one of your values includes the ampersand, '& '? If so, change the character that marks the substitution variables for something that does not appear in the values of the arguments. Example of RPF

  SET  DEFINE  ~
  

  To include spaces in a value, quote the variable when it is used after the = sign in a statement to DEFINE, as you already:

  DEFINE     this_x_id     = '%1'
  

  and also when you call the script. In other words, you should do something like this:

  SELECT DISTINCT
       '@weekly_one_alf'
       , '''' || fallennr          || ''''
       , '''' || alf_login          || ''''
       , '''' || int_fallennummer     || ''''
       , '''' || schaedling          || ''''
  FROM     (SELECT ...
  

  in your main script, weekly.sql.
  You can use either single - or double - quotes. Most people use quotation marks, because they fear that the confusion in the code.
  Whatever you use, the value can contain either.

• for loop in formula node does not

  Hello

  I; m trying to use for loop in the node of the formula, but it is does not work. I want the output (y1) product value in certain range (a and d, and of course one is smaller than d). I ' do not use primitive labview since a and d are keep changing (both are variable). I tried to put "return 0;" after the y1 equation but the error popup.

  The issue of the loop works not because it gives the last value (I average would be ""). It does not begin with an (initial) value.

  Please help me how to solve this problem...

  Pls ignore other variables not used in the equation. Thank you!! A lot

  Your code works.

  

  But why you use loop?
  You get the last value, so you can get it in a single step with x correct;

  Also why you say that can not use primitives?
  If you use wire instead of terminals or local variable States values constant.

  Y1, y1_2, y1 3 is the same values calculated differently.

  

• For loop creates 1 d data table

  Hello, I am building the circuit below, and I'm running into a lot of problems with the loop, creating a table 1 d of data from certain types of data such as the ERROR OUT and the VISA NAME of RESOURCE. I understand why it does this, but I only need the last value in the table (the value of the last iteration of the loop for). This is true for me for the error, resource name of visa, and I was thinking of using the Boolean value that indicates when the for loop.

  Is there a simple way to extract the last value in the table 1-D so that it is correct to pass along trails, VISA and ERROR type?

  You actually create a block diagram, not a circuit.  A circuit is an electrical system including devices and wires.

  If you right-click on the tunnel and choose disable indexing, then you get the value of the last iteration rather than a 1 d table.

• While the loop Tunnel help

  I have a variable inside a while loop, that I want to access outside the loop, that is, in my VI, I have two indicators, one inside the loop and the other outside the loop.  The variable is incremented on each iteration.  However, I am not able to see this iteration of the loop.  I see that the last value of the variable.  Is there anyway for me to access the variable inside the loop as it is running.  In regards to my VI, is it possible for my indicator "inside" correspond to the indicator 'outside '?  Any help with this will be appreciated.  Thank you.

  Kind regards

  David

  Yes.  You must use a local variable of the 'Inside' indicator that writes to the indicator 'outside '.

  There are other ways to do so, such as pass the data via a queue or a notifier.

  The concepts of tunnels, flow of data, and that data is not available to that structure, it is finished, is all notions of LabVIEW.

• Aliases for columns in explicit for LOOP sliders

  Hi friends

  In the below block (forloop) I don't get countsal values, but when I run the query, it gives the County. By this (COUNTSAL) the below if condition fails .i don't know why it is failing.

  But when I use it with a simple loop gives a correct result.

  FOR LOOP:

  SCR CL;

  SET SERVEROUTPUT ON;

  DECLARE

  CURSOR C1 IS EMPNO, ENAME, COUNT (SAL) SELECT COUNTSAL OF THE GROUP EMP BY EMPNO, ENAME;

  SHEIKYERBOUTI C1% ROWTYPE;

  BEGIN

  TO IND IN C1

  WHEN the OUTPUT C1% NOTFOUND;

  DBMS_OUTPUT. PUT_LINE (IND. EMPNO);

  DBMS_OUTPUT. PUT_LINE('SALCOUNT:'||) SHEIKYERBOUTI. COUNTSAL);

  IF SHEIKYERBOUTI. COUNTSAL > 0 THEN

  DBMS_OUTPUT. PUT_LINE ('NAME' |) SHEIKYERBOUTI. ENAME);

  END IF;

  END LOOP;

  END;

  simple loop; (get a correct output)

  SCR CL;

  SET SERVEROUTPUT ON;

  DECLARE

  CURSOR C1

  IS

  SELECT EMPNO, ENAME, COUNT (SAL) COUNTSAL OF THE GROUP EMP BY EMPNO, ENAME;

  SHEIKYERBOUTI C1% ROWTYPE;

  BEGIN

  OPEN C1;

  LOOP

  FETCH C1 INTO SHEIKYERBOUTI.

  WHEN EXIT C1% NOTFOUND;

  IF SHEIKYERBOUTI. COUNTSAL > 0 THEN

  DBMS_OUTPUT. PUT_LINE('NAMES:'||) SHEIKYERBOUTI. ENAME);

  END IF;

  END LOOP;

  END;

  Please suggest me.

  Your code is the missilg LOOP keyword. Also, loop for CURSOR automatically closes after extraction of all lines - no OUTPUT WHEN you have to. But the key is to loop to extract CURSOR loop lines said variable registration - a following KEYWORD, IND in your case:

  DECLARE

  CURSOR C1 IS EMPNO, ENAME, COUNT (SAL) SELECT COUNTSAL OF THE GROUP EMP BY EMPNO, ENAME;

  BEGIN

  TO IND IN C1 LOOP

  DBMS_OUTPUT. PUT_LINE (IND. EMPNO);

  DBMS_OUTPUT. PUT_LINE('SALCOUNT:'||) UNRELIABLE COUNTSAL);

  IF COUNTSAL > 0 THEN.

  DBMS_OUTPUT. PUT_LINE ('NAME' |) UNRELIABLE ENAME);

  END IF;

  END LOOP;

  END;

• For loop within a while loop

  I have for loop within a while loop... admission to the for loop N comes from the VI selection... the while loop I a condition essentially statement it stops just after to finish all the iteration in loop...

  Entrance to the N loop is bascially driven by a local variable... that's the problem Iam having:

  When I press the Start button to run the program... regardless of the output of the select VI is gives the N of the for loop, then the loop starts and then ends in place... and when the output of the select statement takes a different value (the N of the loop for) loop not work until I restart the program again... What can I do so that the for loop runs again for another value of N, the RUN program button is enabled.

  1. clean your diagram.  Style guides suggest keep the pattern of a single screen.  With a little effort, I was able to get your DB less than 1600 x 1000 pixels.

  2 then I can see (some) it happens all at once. This thing does nothing?

  3. local variables can lead to race conditions.  Output in Angle position may be a race condition, although is probably not what you wanted to do.  What does the wired local time at the moment present terminal meter? (Ooops! Two controls with the same name - which can be quite confusing as well!)  If you need or want two components of façade having the same text, use the legends.  Make the labels is different so the comic is more readable.

  4. having more than one Dequeue function on the same queue will lead to unpredictable results.  When an item is removed, it is removed from the queue and is not accessible to any other Dequeue function.  In parallel loops, you have no way of guessing which Dequeue will seize any particular element.

  5 use Boolean reverse instead of Select with wired False to true and true cable at the entrance to false entry. Better, just make the case of forgery in the structure of the case within the for loop the real deal. No required reversal.

  6. I was not looking for to determine the logic of the code within the structure of this case. It seems I could have posted a much simpler way to do this several weeks ago.

  7. use multiply from the Digital Palette rather than a node form multiply by 4 or 1.8. Uses less space BD and is much easier to read.

  8. as has been suggested, learn how to work the machine architecture and the State of producer/consumer.  They can make your life much easier.  Do not try to convert immediately to these models.   It's too much bite to at some point.  Learn how they work first.  Make a few simple examples.  Then rewrite this program in this format.  Probably faster than fixing what you have now.

• FOR loop does not update the local Variable

  I am newer to labview, and I can't wrap the head around why not a habit of local variable to update in the code if it updates on the dashboard. Anything im missing?

  Assume that you are talking about the local variable of the 'State of the cell. The terminal updates every 500ms in the small top loop, the local variable indicates simply that the indicator and thus updates also.

  The problem is "dataflow" and you need to familiarize yourself with the concept!

  Once the while loop starts, the local variable is reading and inside the loop begins. Most likely, the local variable is read before it is updated in the small loop, so most likely returns the value of a fade on the first iteration of the while loop. Now the small loop continues to go twice per second for about five seconds. Only after the loop FOR (and everything else inside the while loop) completed, the while loop will go to the next iteration, date on which the local variable is read once more, this time with the last value of the last for loop iteration of the previous iteration of the while loop.

  In summary, the local variable updates very well, it's just that the code does not read the new value around most of the time.

  Your VI is full also potential competition conditions caused by the over-use of the local variable. You need to respect the proper execution order by eliminating local variables.

  So what is the solution? Hard to say without knowing what the VI is supposed to do. Most likely, you will need to remove the inside OF the loop and use it outside while loop for everything.

• jump on a for loop

  Hi guys,.

  I have the impression that this is a stupid problem and know the solution if probably obvious, but I can't seem to find it

  I have a loop with several inputs and outputs in a Subvi.  When the Subvi is run all entries are read, the loop is skipped, and the outputs are sent.  Does anyone have any idea why the for loop is ignored?  Everything seems to be wired corretly?...

  The vi is attached.

  Thank you!

  I can't open your code due to my having LabVIEW 2009, but here's one thing to check: do you have automatic indexing on at all?  Perhaps, he does not run the expected amount of time due to a table being wired like 'auto-index' to your loop for?

  Another thing to check is try to place an indicator on the output of the variables 'N' and 'i' of the loop (letters of blue boxes that appear automatically).  That should tell you the "N" land of shadow of time it will perform an iteration and the value of the current 'i' reiteration.

  When you use the execution to highlight, you see it execute the code inside the loop?  If so, how many times?  And how did you expect?
