• Create a table in a loop 'for' (reset the number of loops)

  Hello

  I try to incorporate a signal of acceleration from an analog input CRIO to get speed and then further integrate to get the moving of a vibration system.

  I understand that to achieve integration, a table must be fed in. My problem is that I could not buffer the signal in a buffer block, as I couldn't find buffer blocks. so I decided to create my data table by using a loop "for". The nests of the loop 'for' inside a timed loop. The problem that I'm stuck on is how to reset the loop 'for' in order to fill the buffer with each iteration of the outer loop timed.

  I enclose the code if that helps. Note that I use labview in 2013.

  If anyone who has encountered a similar problem before can help me, I would be gratefull.

  You can use a shift register initialized as inputs to your curls, to build your table of one. However, you realize, don't you, that the execution of your program as written loops as soon as the computer can spit out responses, then the output array may contain several points that took place before the entry has updated? Assuming that your thing cRIO (I've not worked with these) has integrated into its routine acquisition of calendar data, I suggest you put that inside the loop to get a data point by reading.

  And do you really want your graph to distance for update only every thousand points (points of acceleration million) speed?

• Table row with loop for each group to set the variable.

  HI: There is probably a simple answer for this, but I don't the have not found...
  
  I have a single row table to move through a group to set a variable containing a sum running. I'm not display the amount in the table but when I saw the report, I see that the table is expanding (add lines) for each loop.
  
  The only line table has 3 columns.
  
  1st column
  <? for-each: AC_GROUP? >
  
  2nd column
  <? xdoxslt:set_variable ($_XDOCTX, 'xAmtVar', xdoxslt:get_variable($_XDOCTX,'xAmtVar') + CURRENT_AMOUNT)? >
  
  3rd column
  <? end foreach? >
  
  Can I use <? for each group? > or something else. My requirement is to set the value of the variable with the total running, but because the loop is adding lines for each value he travels (though not displayed), it's also affecting other areas of the presentation of the page.
  
  Hope it makes sense. Thanks in advance.

  You can do it many ways.

  No need to loop
  You can create a variable and specify the amount of the sum directly to that.

  or

  loop through, then add as you do.

  give any space or enter characters in a word between them, just put it in a single form field will be

  But as I said, I'd definitely go with the first option.

• Update a table in a loop with a table, not a single value

  Hey everybody,

  I'm new to the Forum, but I do LabVIEW for almost a year now.  I work to make my code much more simple, but I encountered a problem that I can't seem to overcome.

  Say I want to graph a numeric control.  I'm updating the digital control to 5 and 5 graphic updates.  Whenever my loop is executed, the 5 is reloti.  Easy to see that the updates fast loop, my FP will have too much processing time.  How to pass control to an array and only draw table each, for example, 10 iterations of the While loop?  I thought using the 'i' in the While loop and a structure case (use is equal to? 10 as the true to update case).  That doesn't really seem to be the answer... Any help is appreciated.

  Hi, Mr. Bass,.

  Thank you for your post and welcome to the forums of NOR.

  If you want to update every 10 iterations, for example, you can use "Quotient and remainder" LabVIEW function found in the palette of the digital - divide the number of iteration by 10 and check the rest, if it is equal to zero then you're on the 10th, 20th, 30th, etc the iteration. You can then use a case structure and write your chart in the case of true, with the condition is true, if the remainder is zero.

  Let me know how you go with this method.

  Thank you

  Hello

  As you discovered, you cannot use SELECT DISTINCT and sequence. NEXTVAL in the same query.

  You can SELECT DISTINCT in a subquery, like this:

  CREATE TABLE     student
  AS
  WITH     distinct_ids     AS
  (
       SELECT DISTINCT     student_id     AS id
       FROM     students_table

  SELECT     st_seq.NEXTVAL     AS st_id

• How to build a table inside a loop

  Hello world

  I have a fundamental question on labview. I would like to create a table in a loop 'for' in this way:

  inside the loop, if a condition named 'A' is true, then I add a new value to the first column of the table.  Otherwise, I have create a new column and start adding values in this column when the condition 'A' is checked, etc.

  I put an example of a VI when the 'A' condition is "improving the loop + 1 is not divisible by 5" and the values in the tables are to increase the loop + 1. The loop stops when the increment = 25.

  In this example, I have a single column with the values [1 2 3 4 6 7 8 9 11 12 13 14 16 17 18 19 21 22 23 24]

  while I wish I had a table of 5 columns:

  1 6 11 16 21

  2 7 12 17 22

  3 8 13 18 23

  4 9 14 19 24

  Note that this is just an example. More generally, the table may contain columns of different lengths.

  Thanks for your response

• Sorting table 2D with header?

  I'm not trying to apply anything in particular. I'm just wondering what would be the best aproach to solve this problem, if I asked.

  If I have a table 2D of strings with columns that contain text, others that contain numbers or timestamps, and the first line is the header, how I would go about how to sort on a particular column? The results did not come from a query of database so not "order by".

  I thought to use ActiveX calls to Excel. Another possibility is to use a temporary table of SQLite. How would you do that?

  SteveChandler wrote:

  In LabVIEW, of course!

  Here's what I'd do:

  (1) remove the header line, leaving a table 2D-data channels

  (2) extract the desired sort column.  In a loop for, browse the table 1 d resulting from chains.  Convert each string the appropriate representation and together with the number of iterations, so the output is an array of a cluster of two elements.

  (3) using 1-d matrix sort to sort the array of clusters.

  (4) browse the sorted table.  Unbundle the meter element, take this rank on the original 2D array and add it to a new table.

  (5) Insert the header row in the sorted table.

• Table of path error 1430 in the loop for

  Hello!

  I have a problem with the 1430 error: path is empty or relative, which seems impossible. The thing is that I have a battery of indicators of path connected to the loop for (check the .jpg and there is no problem with writing to a file by using the paths of an array with the first and last index.) Others are not saved because of the error... to be honest, that all data paths are absolute. Record in the file of the idicator path is the work of a Subvi (merge data vi) but it is in a for loop because I need to make it available to multiple files. There is no error that occur with the work of Subvi to a path. The question is: what labview makes with the paths saved in a table between the loops? I have just run out of ideas so if someone had some time, I would really appreciate for all the tips and ideas.

  Hello again,

  If someone was interested in the happy ending: the solution is: 2 loops for. I think there must be something with the way that labview sends data between iterations. In any case - don't know how much exactly but works

• Import of CSV with loop value FOR

  Good afternoon

  I'm new to LabView and trying to write a VI that will eventually run a set of calculations on a set of data with millions of data points. I want the VI to count the number of data imported points of the. As they are written to a CSV file array. The number of points eventually will help me determine the behavior of the end of my calculations, it is not optional.

  I have trouble getting the file to read each successive line. The value 'for the iterations of the loop"feeds into the 'start reading Offset' «Worksheet File.vi reading» My intention was that this would result in a new line being read in the table with each iteration of the loop. What I get is the first value read over and over again in the first row of the table. Any ideas?

  Thanks for your time and help,

  Wes

• Save control table .cfg with knots of property.

  Hello!

  I have a façade with many (and I mean a lot!) boolean tables in tabs, and I want the ability to save the values selected by the user in a .cfg file, which will be used to make the same selection again without the trouble of clicking on buttons. The only controls that I want to save the value are Boolean tables 1 d of length 7 or 11, and these occur only on some pages tab. others have been setup so that their iteration a false criterion is satisfied and no code is running.

  I managed to get references to each control within each tab, and using a "more specific class' function to reduce it to only the controls in table. However, when this runs, pops up an error of "convert variant data" and use of a probe shows me the reference being called by my property at the time of the error node is to an INDICATOR array, rather than control. I thought that the node of 'controls on the page' and subsequently the control table class specifier would mean that references to other types of table would not make the real case where coming the backup configuration file.

  The indicator in question is a painting of a cluster of two strings and an array of strings, if that makes any sense / has no relevance, and the error occurs on the iteration 1 of the outer loop and the loop iteration 21 internal, corresponding to the control reference 22nd in the second tab.

  I hope that I have the problem clearly.

  There is a property called control? (or indicator?) This will help you sort out them.  I don't remember the exact name of the property, but that should get you close enough to find.

• Synchronize with looping background

  Hello

  I'm doing 2d side view car animation.i have a background loop composition. Sometimes my car has to overcome obstacles on the road.and I cannot do a real synchronization between the compositions of the loop road and objects on the road.i cannot put objetcs open-ended know.how looping you can provide sync them together?

  the second question is have background looping and looping the wheels if I want to stop the animation I use the case expression, but when I want to start that maintain the rolling of composition, but it starts in the first image. How can I fix?

  Try this. Add a null value to the model and name it something like Null 1 speed. Add this expression to the position property of the null value:

  y = value [1];

  v = comp ("BackG.ai Comp 1").layer("BackG.ai").effect ("Offset") ("Center To Shift") .velocityAtTime (.1);

  s = (time - inPoint) * v 2;

  x = value [0] + s;

  [x [0], y]

  This is what makes the expression. Line a grab the current value of Y for the value null. Line 2 picks up speed of the offset in the model of the background. More on that later. Line 3 begins to count the time to the point of in the layer draw and then the time is multiplied by the speed of the offset in pixels per second. Because it is a shift of speed and not a speed of position, multiply this number by 2... Line 4 adds the value of "s" of line 3 to the value of position X of the null value. Finally, you declare the table for position that uses the calculated value for X based on the speed of the offset and the current value of y.

  Now you parent one of the obstacle of the layers to null, set the point in to the barrier layer and the null value at the point in the script where you want the barrier to appear and then down the timeline until it empties into the truck. Then divide you the layer (Ctrl/Cmnd + shift + d) and remove the first folio of parenting. You can then animate position and rotation to simulate the collision.

  Duplicate the value null and join the procedure with your other obstacles.

  One more comment on your computer. I noticed that the speed of your wheels did not match the speed of the background. It is also very easy to fix because you know the speed in pixels per second and if you multiply the diameter of the wheel by PI, you can calculate the circumference of the wheel. Simple math makes the wheels turn at the right speed. The expression in images keys and loopOut() courses can be replaced by this expression:

  v = comp ("BackG.ai Comp 1").layer("BackG.ai").effect ("Offset") ("Center To Shift") .velocityAtTime (.1);

  s = duration * v [0];

  c = Math.PI * width;

  s * c

  You should be able to figure thins out. Here is your comp with changes made to the layer of barrel. Take advantage of...

  On the router, right-click on its icon in the workflow and create a page definition. Then in the file def, add an iterator based on the same view of the table object in the first page, then add a value attribute that is mapped to the managerId in the iterator of the View object. Finally in the router, you can write EL expressions along the lines of #{bindings. ManagerId.inputValue = 200} or #{bindings. ManagerId.inputValue! = 200}.
