Create multiple VIs using a for loop

Hi,
I'm still pretty new to LabVIEW, so this question might be easy for you guys here..
I'll simplify what I'm trying to do.
I've got two numeric controllers that act as the rows and columns of a matrix.
I'd like to take those numbers from these two controllers and use them to create a matrix of a certain picture.
Example:
The rows controller is given 3, and the columns controller is given 4.
Using these numbers I would like the end result to show a certain image (let's say, a cube) multiplied on a 3 by 4 matrix.
Let's say the picture is an X, then the end result should be:
XXXX
XXXX
XXXX
I think I should be using a double for loop (one inside the other obviously), and I should also create the "position" property in order to display each picture of the cube in it's right place.
The problem is that I don't know how to CREATE the pictures over and over again, while being able to control each one's position property.
Any help would be GREATLY appreciated!
Solved!

1) By "multiple VIs" I meant that I think that I need to create express VIs on the fly while running the for loop. I might be totally wrong here.
2) Yes, by "numeric controllers" I meant numeric controls in the front panel.
3) The matrix I'm referring too isn't an object nor a VI in LabVIEW but a virtual matrix that is the end result. I used the term "matrix" because the end result is actually a matrix (of rows and columns) of pictures..
I'll try to elaborate and even simplify it more:
Let's say I want to display one picture. That's easy, no problem there.
Now let's say that I'd like to display n pictures on a one dimensional array. Just one row.
What I think I need to do is to read from the numeric control in the front panel the number (n) of pictures, and then create them in a for loop, while using the "position" property to set the distance between each picture (using coordinates).
My original question was just like the above, but for a two dimensional matrix/array. So I guess we can even simplify it even more, by saying it's only one dimensional.
My way of action here might be totally wrong, and there might be an easier way or another way to go about this...
Thanks for the quick answer!!

I'm creating an array using a for loop, how do I get the values outside the loop while it is running? thanks

I'm creating a set of values using a for loop and a shift register inside the loop. I want access to these values outside the loop as they are being created inside. When I connect a wire from the shift register to a display outside, it doesn't work. How do I do this? Thank you.

I tried to create the local variable that was wired to numeric indicator inside the loop. If I try to connect this to the analog output outside the loop, the loop just starts blinking and nothing happens, am I doing something wrong? Thanks again.

How to create parallel tasks using parallel for loops

Hi,
I am setting up a program that communicates with six logic controllers and has to read the system status every 100 ms. We are using OPC datasockets for this, and they appear a little slow.
I have created a uniform comm. method for all controllers, and now I find myself programming this method six times to communicate with each system. I am wondering if this could be done more elegant using the parallel for loop, in which case I would program an exchange once and then have six workers running simultaneously. Since a picture is more clear that a thousand words, what I am asking is this:
Is it possible to replace something like
by
and have this for loop running these tasks in parallel (on different cores / in different threads)?
I have configured the loop to create 8 instances at compile, so I would have 2 instances surplus available at runtime if I find I need an additional system.
The benefits of the method show in the second picture to me are:
* takes less space
* modifications have to be made only once
* less blocks, wires and stuff makes it more clear what's going on.
* flexibility in the actual number of tasks running (8 instances available at runtime)
* if more tasks are required, I need only to update the maximum number of instances and recompile, i.e. no cutting and pasting required.
Unfortunately, I don't have those system available yet, so there's no way to test this. Yet, I would like to know if the above works as I expect - unfortunately the labview help is not completely clear to me on this.
Best regards,
Frans

Dear mfletcher,
First of all: thanks for confirming that my intuition was right in this case.
As for your question on the help: below is a copy/paste from the help on the 'configure parallelism dialog box'
Number of generated parallel loop instances—Determines the number of For Loop instances LabVIEW generates at compile time. The Number of generated parallel loop instances should equal the number of logical processors on which you expect the VI to execute. If you plan to distribute the VI to multiple computers, Number of generated parallel loop instances should equal the maximum number of logical processors you expect any of those computers to ever contain. Use the parallel instances terminal on the For Loop to specify how many of the generated instances to use at run time. If you wire a larger number to the parallel instances terminal than you specify in this dialog box, LabVIEW only executes as many loop instances as you specify here.The reason for me doubting if what I programmed would work the way I intended lies in the fact that the help only mentions processors here, which would be interpreted as actual cores. Thus on a dual core machine, the number should be 2.
I think it would be helpful to mention something about threads here, because in some case one would like to have more parallel threads than there are cores in a system.
In mu case I would like to create six threads, which on my dual core processor would be spread over only two cores. Then these six threads run in parallel.I know that in case of heavy math that would not help, but since I am doing communications, which have timeouts and such, and that probably runs smoother in six parallel tasks even though I only have two cores.
Hope this helps in improving the help of the for loop.

Frans

Having trouble sizing multiple graphs using a For Loop in Excel.

I am creating multiple graphs in Excel using LabVIEW but I can only set the size for the first graph. The others are ignored. I am using the Excel Insert Graph Vi. I can change the position of al 4 graphs and i can change the size of the first graph created but not the others. Simply create and save a blank Excel workbook and use it when it prompts for the file. Here is my my code. Will someone please let me know what is going on. Thanks.

Excel Graph Test.vi ‏88 KB

If anyone is still following this thread, I have discovered a solution to the problem of resizing multiple graphs in Excel with the Report Generation Toolkit. The problem seems to occur because subsequent graphs that are added to the report are configured to "Lock Aspect Ratio", which means you cannot assign a width and height to the graph that would violate its initial width/height proportions. I was able to get around this behavior by defining the object's position and dimensions after creating the object, as opposed to defining them at the same time the object was created. This problem will be fixed in a future release of the Report Generation Toolkit. For now, you can fix the problem yourself by modifying vi.lib\addons\_office\excel.llb\Excel Insert Graph.vi. Here is a screenshot of the affected area of code as it is currently implemented:
And here is a screenshot of what the code looks like after my modifications that fix the problem:
By assigning the dimensions after turning off the "Lock Aspect Ratio" feature, we see that all the subsequent graphs are sized correctly.
Please let me know if you have any questions on this fix.

Creating multiple mailboxes using Powershell for users who already exist in AD

Hi there,
Wondering if anyone can help, I am wanting to use Powershell to run a command which references a CSV file to create a mailbox for a user who already exists in AD.
It needs to reference the username, to ensure the correct user has a mailbox created (as mentioned they exist already in the domain), place them on a specific database (e.g DB1) and assign them an email address as well as possibly an alias email address
too.
Can anyone provide me the headings of the CSV file which would be needed as well as the powershell command to run. It would be great too if I could also set the quota sizes for the user at the same time of creating the mailbox, but if not possible or complicated
I can run a script afterwards to do this. I would only want to warn them when their mailbox is 1.5GB in size and stop them sending when it reaches 2GB.
Thanks

So create a csv file with the following headers and data
UserID, Alias
UserID should be the user SamAccountName, and the Alias is the Mailbox Alias that you want to set. Supposing that the csv file is named users.csv and located under C:\ , open the Exchange Management Console and run:
$users = Import-Csv c:\users.csv
Foreach ($user in $users) {
Enable-Mailbox -Identity $user.UserID -alias $user.alias -database 'DB1'
Set-Mailbox -Identity $user.UserID -IssueWarningQuota 1.5gb -ProhibitSendQuota 2gb

Creating multiple profiles, using unified profile types, to store multiple values for same properties

Hi All:
I am trying to create multiple profiles, using unified profile types, to
store multiple values for same properties. Here my intention of using
'unified profile types' is to create multiple profiles (to store multiple
values for a property). All the properties are stored in the same database
maintained by Personalization server. Also, I am trying to use the same
'USER' ejb as profile class/home/pk/jndi.
The scenerio is,
define unified profile types (Business, Vacation) using Personalization
admin tools, using com.beasys.commerce.axiom.contact.User,
com.beasys.commerce.axiom.contact.UserHome,
com.beasys.commerce.axiom.contact.UserPk,
com.beasys.commerce.axiom.contact.User for Profile Class, Home, Pk class,
JNDI name respectively.
Define Property set 'HotelCommerce' with property
HotelProp as single, restricted, text (valid values Single, Double)
Now you can use the attached jsp files to login as a user and try to set the
property value for HotelProp for each profile. As per my understanding, I
was expecting that I can set different values for the property 'HotelProp'
for each profiles. But unexpectedly, all the profiles get the same value.
Question. is it the correct behavior? if yes, how can I achieve this
functionality?
if not, do you see any problem in my scripts?
your answer asap is appreciated. we need to make decision on using
Personalization server v/s developing our own Personalization server!!!:)
thanks,
-rajesh
PS: I have tried 'Unified Profile Example' type too, but that did not work.

This is not the purpose of the UUP. The UUP is used to allow existing
database schemas to be aggregated with the existing Weblogic Personalization
Server database schema to provide a single, customized user profile with which
to maintain the user properties (
http://e-docs.bea.com/wlcs/p13n/users.htm#1068901 )
If you want to have properties that change value based on some "profile" or
classification of a user, then you should use classifier rules to change the
user from "OnVacation" to "AtWork" or "AtHome". You can use these classifier
rules to select content for the user or conditionally execute logic (

Creating an array in a 'for' loop (resetting loop count)

Hi,
I am trying to integrate an acceleration signal coming from a CRIO analogue input to obtain the speed and then further integrate to get the displacement of a vibration system.
I understand that in order to perform the integration, an array has to be fed in. My problem is that I could not buffer the signal in a buffer block as I couldn't find any buffer blocks. so I decided to create my an array of data using a 'for' loop. The 'for' loop nests inside a timed loop. The problem that I got stuck at is how to reset the 'for' loop in order to refill the buffer again at every iteration of the outer timed loop.
I have attached the code if that helps. Note that I am using labview 2013.
I would be gratefull if someone who had encountered a similar issue before can help me.

Dear Altenbach,
Many thanks for your reply.
I need to make it clear that I have not had enough hands-on with labview, I have only used it for sometime in the past and now I have to in order to perform some active damping on a 50Hz running machine. I must stress the fact that what i find more intuitive to do in a different programming language (matlab or C) is not as straightforward in labview. so please bear with me if my code has basic mistakes .
All what i am trying to do is obtain the speed and position from an acclerometer signal. unfortunately i dont have a position sensor so i have to measure acceleration then perform time integrations in order to obtain the speed and position respectively. I am using a compact Rio (later in FPGA mode) to take physical measurements of acceleration from the vibratory machine and where i managed to do this bit successfully. when it came to performing the integration, i had to create an array inside my timed loop since i couldn't find a buffer block. I implemented a 'for' loop inside a timed loop in order to build the array. however i got stuck at resetting the count of the 'for' loop in order to refill the array with new values at every new iteration of the outer timed loop. unfortunately, even a sensible answer has been suggested before, i dont seem to have been capable of doing it yet. I really spent all my day trying to figure a way out but not achieved it yet, nevertheless I have learnt many many things by playing around.
I would be gratefull if you could comment on a possible way of doing what i am trying to do.
Kind Regards

Using a For Loop Index for Array Element Number?

Hi. Thanks in advance for the help. I can't seem to find what I want to do here using the search function... probably because I don't know how to frame the question appropriately. Ignore the title to this post cause it's probably wrong vocabulary for what I want to do.
Here's the situation:
I have a 2D array where the first column is the X data and each subsequent column is Y data (call it Y1...Yn). The n-value varies from run to run (some runs have 4 columns of data, some have 20), but that is easily gathered when reading the data file. I need to perform a number of operations on each set of data, the least of which is smoothing the data and graphing it, so I'm limiting my discussion to these 2 operations.
What I want is a for loop structure where the indexing of the loop tracks the Y1...Yn columns, grabs each column for the iteration, performs the relevant analysis, and spits out the result, but in a stackable manner. Thus the title; I want to use the for loop's index to mark the array element for building a new array.
See the image attached. A 2D array of 9 columns (X, Y1...Y8) is analyzed such that each data set, (X, Y1), (X, Y2)...(X, Y8) is bundled, graphed, run through a B-spline Fit, of which is also graphed. I need to replace this with something that looks like the for loop structure shown.
I just don't know how to get those two data bundles [(X, Yi) and it's smoothed pair] out of the for loop in a stacked set from every iteration of the for loop.
Again the title, I think I want to build a new array where i use the index of the for loop to control the entries of the new array. But I can't see how to do that.
Any help would be appreciated.

Hello H.R. Dunham, and welcome to the forum!
It seems that you may be looking for Auto-Indexing, a basic feature of loops in LabVIEW. You'll need to transpose your array before wiring it into the for loop, as elements are auto-indexed by row before column, but at that point you should be able to operate on each column and output an array of n cluster elements corresponding to your input columns. Auto-indexing tunnels look like brackets to indicate each element will be indexed automatically- this should be the default when wiring an array into a for loop or when wiring anything out of a for loop.
As for how to build your pairs, I suggest removing the X column and creating a "starter" cluster containing your X data and placeholder Y data before entering your "Y" processing loop. Use the bundle by name function in the for loop to insert your processed column data into the cluster and auto-index the cluster output. Flow would be something like this:
1) Gather data
2) Split X and Y using standard array operations
3) Create "template" cluster with shared X data
4) Pass template cluster and Y-column array into an auto-indexed for loop.
5) Insert processed Y data into cluster inside loop.
6) Auto-index cluster data out of loop.
This tutorial is probably also a good place to get started:

First time i am trying and database created in noarchive log. Though i was not able to successfully backup & recover, i got clarity on the concepts. (I am learning on my own- so need a do a lot of research to clarify doubts).
Coming to the point. Since two database i can open two em consoles and do operations at same time. But in command mode when i try i am facing issues. At one point of time i am not able to fine which database is running and how to enable or disable the other.
I logged in and execute shutdown immediate. It shutdown one database. I switched the oracle_sid and tried to shutdown second, but it did not happen. Then i did it from EM.
Then i tried to restart the server.. I executed the following commands.
C:\Documents and Settings\MaverickBull>set oracle_sid=ora10g
C:\Documents and Settings\MaverickBull>sqlplus sys as sysdba/oracle123@ora10g

ERROR:
ORA-12560: TNS:protocol adapter error
I am getting this error+
I tried from EM & successfully opened.*
Current Status shutdown
Operation startup database in open mode
Initialization Parameter default
Are you sure you want to perform this operation?
When i checked my TNS its showing both in same port.!!. My TNS looks like this.
ORA10GRC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = renji)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10grc)
ORA10G =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = renji)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10g)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
Please Help How can i manage both database from the cli. I mean switch between database, shutdown,startup both the database etc. Also at one point of time, how can i check which database i am working with.(say for example, i forget which ORACLE_SID i set)
Thanks

One more clarification..
The TNS Shows
ORA10GRC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = renji)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10grc)
ORA10G =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = renji)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10g)
Both are listening on the same port..
From the EM Screen
Status Open
Host renji
Port *1521*
SID ora10g
Oracle Home D:\oracle\product\10.2.0\ora10g
Status Open
Host renji
Port *1521*
SID ora10grc
Oracle Home D:\oracle\product\10.2.0\ora10g
Is this possible. Two db listening on the same port at the same time??.. I opened both simultaneously in multiple tabs. saying port 1521.
Thanks

Using a For loop to call one array element at a time

I have been working on a VI that reads a GPS unit, parses the data, outputs what I need, compares the actual GPS location to the desired location, determines a desired heading and moves on from there. My question pertains to the number of desired locations I can input right now. I need to be able to input a predtermined number of locations (not just the one that I can input right now). I was told that it is possible to use a For Loop with an array and have the first set of Lat and Long values run through the VI and when everything is complete that the next set of values will be chosen. Does this mean that I need to put the entire VI inside a For Loop and have the array update as soon as the VI has completed its first mission? I understand the concept of how this work from other programming languages but I'm not sure how to implement the solution in LabVIEW. Any help would be appreciated.

Here is a portion of the VI. I need two separate arrays, one for Latitude and one for Longitude, of the same size.
I don't see any arrays in your code. Do you want to generate arrays form individual data points or do you want to process arrays, one element at a time? Both can take advantage of autoindexing. Here's a simple picture.
Your VI contains a weird mix of DBL and EXT precision. Most likely all you need is DBL. Keep your representations consistent!

Transposing data in an array using a For Loop

I am trying to transpose some data in an array using a for loop starting from the size of the array then decrement down to 0. Can someone please help if you have an example?
Solved!
Go to Solution.

I feel as if reverse 1D array may help
Edit: misunderstood what your second post meant.

Weird problem with loading data from an XML using a for loop

Hi,
I have a strange problem. I have encountered this thing many a times but still don't know the proper workaround for it.
I am trying to load swf file, a video file or an image. They can be present on a local system or on a remote server also. All the entries corresponding to the files to be loaded is made in an XML file. I traverse through the nodes of the XML using a for loop. On the complete event of loader info, example:.
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
I fill a container with the loaded data.
My problem is when I am using for loop it doesn't works properly but if i use a statement like this:
someFunc()
     if(i<arr.length())
     ... do something...
     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
private function onComplete(e:Event):void
... do something...
i++;
All files are loaded properly.
I think this can be because the for loop processes pretty fast but the content takes time to load, which ultimately leads to some wierd results.
Please let me know how can this thing be done correctly by using a for loop also.

You don't want to use a for loop to load several items. The way you almost appear to have it is the proper approach... load a file and use the completion of its loading to trigger loading the next file.

Creating a PO Using BAPI For Multiple PLants Or Multiple Line Items

Hi All
    Can you please suggest me how to create a Purchase Order Using BAPI_PO_Create1 for Multiple Plants Or for Multiple Line items. The Requirement is like the PO is for single material for single vendor but for mulple stores i.e plants
NOte: Suggest me the Creation of PO for MUltiple Line items or for multiple plants Using BAPI . Hope you people will give me the needful.
Regards
Shivakumar Bandari

Hi,
Here is the sample code to do that...
*---> po header data
wa_poheader-vendor    = your vendor..
wa_poheader-doc_type = Your doc type..check with Functional contact....
wa_poheader-purch_org = Purchasing Org..
wa_poheader-pur_group = Purchasing Group
*---> po header data (change toolbar)
wa_poheaderx-vendor    = 'X'.
wa_poheaderx-doc_type = 'X'.
wa_poheaderx-purch_org = 'X'.
wa_poheaderx-pur_group = 'X'.
*---> poitem data
data: item like ekpo-ebelp.
item = '0010'.
loop at t_parts.
it_poitem-po_item = '00010'.
IT_POITEM-PLANT    = Plant..
IT_POITEM-STGE_LOC = Sloc...
*---> poitemx (item data change toolbar)
it_poitemx-po_item = '0010'.
it_poitemx-po_itemx = 'X'.
IT_POITEMX-PLANT    = 'X'.
IT_POITEMX-STGE_LOC = 'X'.
*---> add record's to internal table
APPEND: it_poitem,
         it_poitemx.
endloop.
*call bapi_po_create1
CLEAR v_ebeln.
CALL FUNCTION 'BAPI_PO_CREATE1'
    EXPORTING
      poheader         = wa_poheader
      poheaderx        = wa_poheaderx
    IMPORTING
      exppurchaseorder = v_ebeln
    TABLES
      return           = it_return
      poitem           = it_poitem
      poitemx          = it_poitemx.
*---> check the return table for error message
READ TABLE it_return WITH KEY type = 'E'.
IF sy-subrc NE 0.
    CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
      EXPORTING
        wait = 'X'.
endif.

I have used a 'for loop' to create an array of output data, however I want the each of the data sets from the array to be placed into a 1-D array. How do I concatenate the output of the for loop into a 1-D array?

I am using this to create a data set that will be passed as an anolog output therefore it needs to have the correct array dimensions to go into the analog write vi.

I'm updating my request... I've figured out how to do this by copying an example that uses a simple FOR loop (as seen in the attached current version of my VI). My question now becomes this: Is there a way to save the Y values corresponding to those X values into two more arrays? That is, just for argument's sake, let's say I took the first 100 elements from the X array, and found them to be positive. Then I would like to take the first 100 elements of the Y array and put them into a 'Y Values for X > 0' array. ...And likewise with the negative X values, they should have a separate array of corresponding 'Y values for X < 0' array.
I can see that I should somehow save the indices of the positive X values from the large arrray wh
en I sort them out, and use those indices to pick out the elements from the main Y array with the same indices.
I just can't seem to set up the code necessary to do this. ...Can anyone help, please?
