• 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

  Try to watch this VI I wrote, it takes a 1 d array and puts it into a 2D array based on a threshold. I think it's a pretty good example on how to insert a table of works. I hope it helps

• 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 in the loop for

  Hello and thanks for reading.

  I have a program c ++ that I use for the list of available CCD cameras on computers in a local network. For this I built a VI, lets call it List.VI, I have provide a string containing the name of the computer. The back is a list of the cameras available on the specified computer.

  Now, I want to use this VI to analyze multiple computers and store back in an array where each element represents the return of a computer. I don't know how many computers I use the size of return is specified by the number of elements in the input array. The VI I am providing is not functional on other computers, but it will give you an idea of what I meant.

  I joined my List.VI in a loop, and it generates 3 messages back (in my example code). My problem is the function replace table subset. It requires a table control text (which I call fake table) in which I am suppose to replace something that works very well for a single loop. But when the iteration of the loop and the second return of List.VI is placed in the second element of the dummy array, but the first element is lost. I need to find a way to either stack the items back or somehow update the items already returned in the dummy array before filling the other. And I can't do it with all the functions available. There are all other functions of program designs that can help me?

  Advice would be much appreciated.

  Best regards

  / Mikael

  Here you have some misconceptions. Why so complicated? All you need is a FOR loop autoindexing.

  

  (In the most general case, you build your table in a registry to offset, but not here. You can't replace an element that does not exist)

• Excerpt from my table using the loop For

  Hello

  I have this loop to create a 2D array. The result is on the table below. I want that this 2D table should be fully completed and compiled, then it will be sent out of the loop.

  I don't want to extract the value of table 2D is a loop. This is the problem that I am facing.

  My ultimate goal is to extract the individual number of the final table of the 2D table line and be an entry for other functions.

  Please help me. Thank you

• 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.

• Creating tables in a nested for loop

  Hi all.

  I was stuck in this problem for quite a while now and I still don't know how to continue. Some outside the entrance would be greatly appreciated!

  I'm doing the following:

  -Take an array of numbers, to check if they are within a certain range (e.g. between 2 and 4)

  -Build two new arrays: one with all the numbers that are inside the beach and the other with the rest.

  An additional condition is that the amount and value of the range conditions will change (for example, it could be between 2 and 4 only / 2, 4 AND 6 and 7 according to the entry)

  To treat this, I created two nested for loops - one that goes on a table that contains conditions of the beach and inside that actually go and check if the values are in the range. I think I did that part successfully, but the next part is confusing to me - how to actually create the tables separated within two loops for?

  My apologies if I did not explain it well. Another method to support this problem is I want to translate following LabVIEW:

  Ranges of table / / [1 5 7 10] exodus-> This means we want to divide numbers based on those who are in (1,2) and (4.5) against those who are not

  Table of values / / [2 3 6 11 3]

  EndOperationDelegate table / / array of values within the range
  Table outValues / / Array of values out of range

  for m = 1:size (ranges)

  for n = 1:size (values)
  If (THE NUMBER IS on the INSIDE of EACH RANGE)
  EndOperationDelegate = [EndOperationDelegate NEWNUMBER]
  on the other
  outValues = [outValues NEWNUMBER]
  end

  end
  end

  Sounds easy enough, but it gets so chaotic with Labview that I don't know what to do. I have attached a reference image - insertion in the array function is not in fact add to the table, it creates a new table. How can I save that for when the nested for the ends of the loop?

  I have seen a few examples with shift registers which lie in a loop and I couldn't successfully that transfers in my block diagram.

  Any help/direction would be greatly appreciated.

  Hello!

  See the following example to understand how you can create a table in the loop For

  

  In your case, you also can uce conditional terminal to create a table only when then located nearby. It makes the code much cleaner that the structures of the case

  Hope this helps, if not, let me know if I can help you!

• Automatic indexation 2D array in the loop For - what is happening?

  I found many sources dealing 1 d tables in a loop For or a While loop, using automatic indexing, but nothing on the tables of higher order.

  I work with a program that feeds a 2D array in a loop (see table).  From what I see, it looks like this the results of automatic indexing in a 1 d, the first column of table 2-D table.

  This is the expected behavior, and it would hold true for arrays of higher order, table 3D for example?

  Is it possible to refer to the second column rather than the first?

  N ° it auto-index through a line at a time table.  You will get a 1 d table which consists of all of the columns that make up each row in each iteration.

  This is the expected behavior, and it would hold true for arrays of higher order, table 3D for example?

  Yes.  Automatic indexing on a 3D Board will give you a table on each iteration of each page 2D.

  Is it possible to refer to the second column rather than the first?  This question applies once you understand the first response.

• Build a table 1 d of sequential data for analysis

  I have an executable that needs to cycle at least 10 times and then check to see if the last three load average values lower than 5%. If so, I can cancel the executable, but otherwise I have to keep cycling until this is true. As it is now my executable is not fully implemented for this last requirement because I'm stumbling over how to build my data table. I tried a few methods different but all keep changing one value with one another, and I'm not sure how to implement some of the loop I saw here in similar cases. I have now so I can build a table once my iterative loop is finished, but I wish it were on the fly and re-enter the cyling process if necessary.

  I would greatly appreciate any help someone who is actually competent could provide. I have attached the code (version 8.5).

  Let's try this one.

  In the table of construction (with the concantinate mode on...) new data are added to the table first, not the last.

  The table is based and as it builds, the first (latest additions) three elements are averaged and then checked against a constraint of difference you set on the top of the screen.

  Sorry for the first code... I have yet to understand all these things of table.

  It works as expected.

• loop for doesn't loop in table built from worksheet

  I'm probably doing sonthing but really stupid...

  first I build and table of data in a worksheet (RefLookup)

  the spreadsheet contains 3 rows above the row is my label (getting by)

  the second row it my face value

  the third row is my minimum value.

  REF is my live stream of data to be searched.

  then, I put this in a loop for loop through the table until she finds that go the Ref data in the lie...

  Then I just stop the loop and the index of output value.

  This index value is the opportunity to review worksheet data and return the label for this index.

  from what I can understand the code should... work. but it does not go past the first itteration of the loop for

  any ideas?

  Please and thank you

  John

  You must set the comma separator, otherwise you get all the data. (read spreadsheet)

  You do this too complicated. Here is the equivalent code. I don't know that it can be much more simplified!

  You don't need the outside while loop. find once is enough.

  

  You probably want to add a "select" after the loop that selects NaN instead of the last value if nothing is found, based on the Boolean value.

• Creating a table of automatic indexing of loop for

  Hello and greetings from a newbie to LabView,

  In my program, I want to write several orders via VISA and read them in order. I created a table of command and auto-indexé to a loop for.

  I want to receive a table of responses, in the order they were read of course. However, I'm not sure what is the best way to do it.

  I'm sure that the solution is simple but have been unable to find one. I have attached the vi for reference. (VISA vi reading is part of the LabView unit driver), which works, but looks like a unmodular approach and inelegant.

  Thank you!

  Simple, you can auto-index the output!

  

• clear the table of loop for

  Hello world

  I have a question about the erasure of history to the table. It sounds simple, but I'm really confused...

  As the example attached below, I've built a table within a while loop and a loop. After totally run the program once, when I run it a second time, it seems that the table has a memory of the last time, that is the size of table does not start from 0, and appears the old number from last time, even through its initialization of the for loop.

  How can I make it go empty each time when I restart the table?

  Need your help. Thank you very much. : )

  You must also have a shift in the loop FOR. This will keep the data for the duration of the program, but it clear at the beginning of the next run.

  

• 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

• loop for and while loop with empty table entry

  Hello

  I have a question with loop and loop.

  When a constant empty array (zero element) is connected to the loop For with "allowing the index", there are no interactions performed in loop For. But, if the loop is replaced by any loop, no problem.

  LabVIEW 2010

  Hello

  It is ok. I have no problem at all.

  For the 'loop' For when you connect the table thanks to indexing, the number of iterations is set to the size of the array. The iteration number assigned to N (in your case 10) is ignored.

  For the 'While' loop the number of iteration is defined by the Boolean Condition and the size of the array is ignored.

• Conversion of data in a table by using a For loop

  I'm trying to transpose data in a table using a loop from the size of the array, and then decrease until 0. Can someone help please if you have an example?

  This looks like a school exercise.

  Determine how to calculate the index in the input array and how to calculate the index in the output array. Use the Index and tunnel exit autoindxing table or Index table, and then replace the subset of the table.
