Retaining the last value without a while loop

Hello

I'm using LabVIEW 2013. My VI is attached. I'll send in a 'Curr. Random random numbers TestPlan Row"time. I'm eager to keep his last number, whenever this VI is not called and then reset the value to its new value whenever the VI is called again and a new number has been sent. Also attached is a screenshot at the VI.

Please note that I can't use a WHILE loop, so it must keep its value in a different way...

Thanks in advance for any help!

Maybe a feedback node?

Read help on registers at offset. Take some tutorials.

Shift registers take a value at the end of the iteration of a loop and return it at the beginning of the next iteration of the loop.

Insert row into table 2D retaining the previous values

Amendment of data entered in a 2D array and also displayed a table. When the time rolls 3 columns of data are held and then created line. Problem is the line moves downwards, but the previous data is not stored. I tried using shift register, but that only auto markings lines table to fill as the iteration of the loop. Looks like a basic really simple problem but going round in circles on this one there...

In this case, the function 'Replace table subset' is what is needed to replace the last values in line with the current values of the user interface.

display the last value

Hi all

I have a questions. It is that I create a Subvi to my table and it can display the last value in the upper part. Below attached snapshots of my programming. I use a number random and STOP for control of you guys let see the whole process of what I want.

but when I change "constant true/false" and using a digital command. and I put it in my program. It won't list down the values and it will not display the most recent value at the top. What is the problem? I was stuck on this problem for a while.

and another question was how to keep the size of the list is constant? for example, I onli wants to view 30readings on my table. as the program continued to run, the oldest value will be overwritten. because if kept under my table more, means memory increase my programming and registration of cause late development. I do not want to happen. So is it possible to maintain the display of fixed table values?

Hi Isabelle,.

I think that the problem causes initialization of a register shift to void / vi. If you initialize a shift register, each time sub vi is called, he will replace value in the registry to offset with initialized value. Uninitialize a registry change to resolve a problem. I've attached a screenshot of my sub vi for your reference.

Close the last tab without closing the application firefox

Greetings!

1.i would like to close the last tab without closing the application. The behavior I expect is the application to open a new empty tab when I close the last tab currently I can't close the last tab which already has some open site in it.

2. when I open a new tab, I have to enter a Web site address. I expect the app to just open a new empty tab and let him to enter an address or not for me.

Thank you for your support. I love firefox for Android.

It is being developed and will be changed to allow the closure of the last tab in Firefox 18 or 19.

Read the last value of a large file of PDM

Hello everyone!

I hope someone can help out me with this one.

I try to put in place a program that can read the last value of one of the large channels of different TDMS files but I just can´t find a way to do it.

I would appreciate help for my little problem.

Thank you very much in advance for your support.

Kasim.

Hello

You can use the following playback TDMS Set Position feature included in the PDM API. This function receives a parameter called "(0:start)", which can be set to 1 to go to end of the file. In this way, you can read the last value written to the PDM file.

I hope this helps!

How can I update the values out of while loop

The LabView waveform chart updates every 0.1 sec.

When a user clicks on a button, I want to LabVIEW to wait 5 sec and beep for 5 sec.

Meanwhile, it should be to update permanently the wavefrorm graph.

When I have the structure case inside the while loop, it interferes with the updates of the waveform graph.

When I structure case outside the while loop, the structure of the case is never executed.

What can I do?

I thought about it using the example of design of producer/consumer model.

http://decibel.NI.com/content/docs/doc-5404

It allows a variable that is updated in a while loop to update outside the while loop while the loop is running.

Static analog output without a while loop?

Hi all

Would like to know if it is possible to set up a card outputs analog instrument (with DAQmx I presume) to have a static/continuous output, without needing to use a while loop. I what would want to return a single value rather than a table or a waveform. It would be similar to option for digital IO cards to have static strings instead of strings of waveform. In the examples I've seen, he always seems to be a time loop is necessary, even if the channel is configured for a single sample, but I think it would be cleaner and easier to control dynamically without the loop (particularly if I run several screws in parallel). My particular application is to configure inputs and outputs analog, then runs different tests with other maps of the instrument. Please notify. Thank you.

GSinMN

No, you don't need a loop. A writing DAQmx for 1Sample game, it's all you need. Please include am image of the pattern block one of these examples. My guess is that the example is simply a way to accept changes in production without having to re-run the whole VI.

How do the last 4 paintings of a loop output For?

Hi people,

I'm almost at the end of my home. I really hope that someone could help me please.
Any input would be welcome. VI attached.

Explanation of VI:
I initialize an array.
The random number generator simulates my entry camera.
According to which iteration it is, the data are added in one of the four tables of output.
"x - y * floor(x/y) ' gives a value of remainder of 0, 1, 2 or 3.
'Case Selector' just add 1 to "x - y * floor(x/y) ' for case 1, 2, 3, or 4.
Pictures 1, 5, 9 etc. are added to table 1 (case 1).
Photos 2, 6, 10 etc. are added to table 2 (case 2).
3, 7, 11 etc. are added to table 3 (case 3).
Shots of 4, 8, 12 etc. are added to table 4 (4 cases).
Average output displays the average value or total divided by the number of photos stored in this table ("Set (IQ + 1)'").

My problems are:

(1) I would like to output only the last 4 sets of data from different average output files, 1, 2, 3, and 4 to 4 (i.e. under .csv what is displayed on the screen in indicators "average output was 1, 2, 3 and 4 at the end of all iterations.)
Where should I put my file save the diagram disabled so that it does?

Put outside the main loop with automatic indexing on gives me a file with all previous data. (This is not feasible under my number of shots should number in thousands)

Put outside the main loop with automatic indexing for off gives me only the last data series. (I need the output for 4 tables, not only the last run)

Inside of the main loop to put (as shown) gives me the same number of files as the number of iterations. (Once again not possible due to the large number of files that will be generated and slow down the camera capture)

In order to capture fast camera, I wish that these 4 files output only once the entire image capture are over.

2) would preferably name the file once and for the program to add "(1)', ' (2)', ' (3)' and '(4)' file name tables"output on average"but appropriate file path controls are an another big headache for me.»»»

3) PS is the initialization of an array enough not to use the memory manager? Or should I initialize 4 Bay?

I am using Labview 2010.

Thank you very much
Charlene

Hi Laura,

I assume that you want to store the 4 x 4 table of average production for the last 4 iterations (correct me if I'm wrong). If so, I've set up the example as shown below:

So, basically, what I did is I created a comparison group to check if the iteration is the iteration total last 4, you have defined. I have included a number to each of the business structures to set in which case it belongs to. The comparator will pass a Boolean result to the structure of the housing that contains the algorithm for writing a file. Since you mentioned that you want to create a file for each of the case, I created as a way to build to create the customized for each case file name. You will notice that there is a concanate string.vi that allows me to customize the name of the file. Since the common file must be exit average, I take the digital constant from the structure of the deal and convert it to a string and concanate to make it in e.g. output average 1. Please note that you need to put a basic path such as in my case, I want to save in the folder named ' New folder (3) "to my office.

The writing on the case folder occurs only if the condition is true (that is, the last 4 iterations of the loop for)

Once done, I created the header and write it in this text file and followed by data from spreadsheet on the next line.

I enclose the code for your reference. I would like to know if this is what you wanted.

Thank you

Return a cell offset from the last value that is true

I'm working on a document where I keep track of the amount of times my pieces band a certain song (this part, I figured out), but I also want to show what we played for the last time, we play a lot of songs the performance greater than 1. I have now a formula as shown below (sheet 1), but this does not automatically refresh when I insert a new playlist (on sheet 2), which is what I want. So, basically, I want to return the date that corresponds to the last time that a certain song is played, will be updated automatically during the extension of the list (on the sheet 2).

I tried a lot of things, but I can't find a way to achieve this.

Some relevant translations:

-Sheet 1: 'Reply music' = last played

-Sheet 2: "Optredens (bezetting)' = (irrelevant) performance--> all in one table, with cells unformatted (all white, without borders, sheet 2) to divide the performance and make it visually more attractive.

I hope that someone of you can help me!

Thanks in advance

It looks like all your playlists are in a table in sheet 2. Ok. It also seems that they are in ascending date order. It's also good.

A way to do it is with the LOOKUP function. Search for the title of the song and have it return the corresponding date of the C column. Search the LOOKUP function in a column from the bottom to the top he will return to the most recent date, the lowest one in the table. The direction she is looking doesn't seem to be documented officially, but I must have read somewhere, maybe in Excel.

A simple formula looks a little like this (but with your name in the table 'table' No 2):

= LOOKUP (C2, Table 2::B, Table 2::C)

Note that the SEARCH will return a 'tight match' if the title of the song is not found in your playlist on any date. It can return a date to a different song. If you think that this can happen, wrap it in an if STATEMENT to check when the game in the D column number is 0.

= IF (D2 = 0, ' ", list of CHOICES (C2, Table 2::B, table 2::C))))

Note: Unlike the RESEARCH, VLOOKUP and MATCH of research from top to bottom.

Take the last value of the timer

Hello

Looking for a help store the timer values.

Set the backround: will be used to gather data for tests on mechanical switch lifecycle sump pumps.

Needs to: number of cycles (lit-shut down-lit), Count time stuck we or off (authorized in time is the estimated time to fill/drain sump), see the amount of time stuck on or off.

I got all of these features to work, but my problem is that when I save to spreadsheet each incriment stuck time power is saved. This could lead to a large number of unnecessary data points. Instead, I want only the last zero no value of the glued power saved timer.

Any help is greatly appreciated.
