Re: 10803, deallocate memory
Thanks fo your answer, but I guess that I need to explain my case more deeply. I use nidaq 7.1. I have suvbi where a buffered continuous data acquisition is done. (ai-config, daq-occurence-config,ai-start and in a loop ai-read). after some time the user can stop acquisition (ai-clear) and start the measurement. the measurement is done in another subvi. again I have ai-config, daq-occurence-config,ai-start and in a loop ai-read for the acquisition. after a data analises the user comes back to the the first window, and so on. this loop is done 30 times. on the 20 loop the ai-read gives NaN, depending how big te buffer of the ai-config has been set.

RE: Info-LabVIEW Digest - 05/14/04
I ran into this as well once at a previous employer (a large telecom equip mfgr), I made this suggestion to the managers: order a server! Servers will usually not be subject to the desktop software licensing requirements, (MS-Office, disk partitioning, case access (installing cards), latest OS, etc...) are offered in rack mount cabinetry, don't come with outrageous video cards, sound cards or modems (nothing to be removed or dealt with re: IRQs) and offer options that might be of value in a test station that needs to run in a 24/7 mfg floor env. like ECC RAM and RAID. If you us MS Windows, IS can create a hardware domain in which you have the ability to install hardware, software, update drivers, etc... without calling IS, yet this hardware domain can be connected to the corporate user domain for access to things like your document space, company intranet, etc. IS probably doesn't even know how to do this, or have dreamt of trying it bat had no application. You've now got IS on your side! One last thing; if you need to send the test station out of house (CM, off-shore), you can still have your own complete network with just a hub and a couple of Ethernet cables. You get the CM to provide a gateway PC (type of use, not brand) to act as a transfer point for YOUR DATA to THEIR network. I was amazed when my test computers were delivered to one CM; they suddenly became the property of the CM's I.S. group, not MINE (read, the --CUSTOMER--). With your own private network, there's no need to wait for your CM network account password to be reset by a monkey with a too many body piercings, colored hair and a Limp Bizkit T who keeps asking you Dude, why haven't you logged in in 4 weeks!

Recently I was required by our IT department to 'upgrade' a couple of networked factory test PCs (still running LV5.1 apps under Windows 95!) to Windows 2000, and since the original PCs were decreed too underpowered, IT gave me a few 'cast-offs', of 400MHz Pentium-II vintage, as replacements. Long story short, at least one of these has turned out to be unreliable for long term use, so now I'm given the nod to buy something akin to the standard-issue current workstation. We've got a corporate purchase agreement with a big computer manufacturer (rhymes with 'hell'), and now I'm told that all such PCs MUST come with a license for MS Office Pro/Exchange/WinServer2003 etc, which adds close to 500USD to the total. The IT line is, 'If it plugs into the network, it must include these licenses'. Plus, W2K is no longer an option, so it comes with WinXPPro, and if you reload the OS, you're unsupported. I'm just curious to hear from some of you folks who work for (or contract for) LMCO, Sperry, Litton, and other medium-to-large corporations, what your experiences are. Are you free to buy your own hardware if it goes on the corporate network, or do you get what's offered? (Usually, I'm more concerned with things like how many open PCI slots the thing has...)

RE: Labview, Linux and databases
First of all, what DBMS are you going to be using? You mentioned MySQL, are you decided on that one? Any serious DBMS will provide some mechanism for communication from a variety of OS platforms. They won't always be the same, but they will be there, and if you architect your software correctly you can hide from the application in general the specifics of how any given instance of LabVIEW is connecting to the database. Second, what kind of data are you going to be storing? If you are going to be working with large datatypes like images or waveforms, you have a much more fundamental problem--ODBC won't work for even Windows. My personal opinion is that ODBC's inherent limitations make it unsuitable for any sort of serious work unless it's your absolute last hope. Third, where is the database itself going to reside? Be aware that database applications are very computationally intensive application--which is perhaps why so many database applications end up using some sort of client-server architecture.

Can Remote Panels be accomplished with the Labview Runtime engine alone?
Hello, I have made several applications within LV 6.1. And made them all available via the web. To use the applications i made an .exe and the supporting installer and the programs still work fine. The question i want to ask, Is it possible to publish the VI using only the .exe? So is having the runtime engine enough to publish the data? Perhaps by making the webpage on another computer and them placing it over. I would guess not. The webserver and its tools to manage the whole thing are probably not available, buth i want to be sure. Thanks anyway, Andries Wim student

Re: Can Remote Panels be accomplished with the Labview Runtime engine alone?
Yes it can! The trick is all hidden in your LabVIEW.ini file. All of the configuration seetings that you configure using the web publishing tools in the development environment end up being saved to your LabVIEW.ini file. If you copy this file into the folder where your exe is located AND name it as My app.ini (where My app.exe is the name of your exe), LV will serve the configured pages. If memory serves me correctly, you also have to make sure the web functions are included in the exe when you do your build. Ben
Re: smooth a single looping step for a biped robot
Hi Tristan, I need a vi to take a waveform, typicaly 200 scans over 1.5 secs, and provide a smoothing/weighting action to join the start and end of the wave. Waves will be played as a loop and provide continuous walking for a biped robot. That is why it is important to smooth/join the start/end. I also need to minimise the effect of the vi on the wave and would like the function to affect as few start/end samples as possible. I have tried looking through some of the filtering vi's but dont have any electronic filtering experience. The vi should not introduce and high frequency bumps at the joining point as the windowed data will be experiemented on using other functions like polynomial, fourier etc. I imagine the solution will split the wave data into 3 different sections: 1, 1st 10 scans of adjusted data. 2, roughly 180 scans of untouched data. 3, last 10 scans of adjusted data. Please let me know if you require more info. Regards Chris

RE: Corporate PC purchases for factory test, your experiences please
All, Thanks for the many replies. Just to summarize and respond: 1. I didn't mean to give the impression that I'm anti-d'Hell. Pretty much every test station I've had responsibility for in the past 5+ years here was built around one of their desktop or small tower configurations. With few exceptions, they've proven to be a reliable choice. 2. I wasn't looking to change the form factor or scope of this existing setup. I just wanted to replace a small tower workstation with a newer one. I've often looked at rackmount/passive backplane/industrial PC setups but they've never (in hindsight) been justifiable for our apps. 3. Being attached to the same corporate net used by every other PC and server in the facility is pretty fundamental to the way we do business. 4. Our 'IT department' consists of two long-term, hard-working regular guys here at our location, and a small army of people at our HQ location and other sites. My argument was with a policy, not with a person. The only thing that seems to have changed about the situation since other, earlier purchases for test equipment use is the level of charges on the invoice for software licensing which I argue is unnecessary, but others tell me is required for corporate liability's sake. While I framed the issue in terms of being a good steward of the company's money, the greater perspective is that it's just a cost of doing business. The PO went up the chain unmodified from the original quote. As I described, that's about 900 USD for a basic PC with XPpro (no monitor), and about 480 USD for additional licenses. If this is the price of feeling good about doing business with MS, well, OK...

Right click on your existing Y-scale and select duplicate scale. This will give you another Y-scale to plot your data against. You can then use the plot legend to right click and associate your data with the new scale on a plot by plot basis. You can add as many legends as you need. You can also switch sides for a scale if you choose. Ben
Keithley 2400 Trigger 2000
Hi, I have tried for a couple of days to let a Keithley 2400 source current and measure voltage and at the same time trigger a DMM2000 on which a current will be measured. This is for use in a LIV characterization. I=92m using Labview but prefer to write directly to the bus instead of using the Labview drivers, which I find a bit complicated to use. First I configure the 2400 with the following commands *RST; TRAC:CLE; SOUR:FUNC:MODE CURR; SOUR:SWE:SPAC LIN; SOUR:CURR:STAR 0; SOUR:CURR:STOP 0.1; SOUR:CURR:STEP 0.0001; TRIG:COUN 100; SOUR:CURR:MODE SWE; SENS:FUNC VOLT; FORM:ELEM CURR,VOLT; TRIG:SOUR TLINK; TRIG:INP SOUR; TRIG:OUTP SENS; Then I write the following to the DMM 2000 to initialize *RST; TRAC:CLE; SENS:FUNC CURR; TRIG:SOUR EXT; TRIG:COUN 100; Now the two instruments should trigger each other. I then write to the 2400 to turn on and initiate the sweep. OUTP ON; INIT; And finally an INIT is sent to the DMM2000 to initiate this instrument This starts the measurement ONLY if the instruments have been turned on just before the program is executed. If I run the full program again it doesn=92t start. What is wrong? If I run the program from the initialization of the 2000 it works well. But if the intialization of the 2400 is included it just wont start the sweep. Any suggestions? Regards Francis

You didn't mention why you wanted to store the instrument state data to a data file. Depending on your need, an NI-Spy log might suffice.

The actual commands you send to the instrument will also be logged.
Re: What's the best way to deal with having different units plotted on the same graph?
One way I handled that is to normalize my several Y axis data, and plot them in % (percent) (scale 0 to 100) so If one column data is voltage, another is current, temperature, etc, I divide each column by its predetermined or assumed maximum, and this will be the hundred percent point. Then I use a single scale with multiple plots. It worked fine with many customers Just my input to that

Programmatically Creating Clusters
I have an file format that lets me store nearly arbitrary (though not nested) clusters in tabular (and binary) form... each column is an element from the cluster, and each row is a complete cluster... so the whole table is basically a cluster array. There is header information in this file that completely describes the layout of the binary table, and this header information is derived from the 'type string' information provided for each labview data type. So, by reading this header information, I can completely describe the type of the cluster represented by the binary table. Now, I know I have some runtime limitations, but my question is aimed at the editing environment. Is there a way to build a cluster using the VI server? I imagine the executing VI creating a new VI and then performing operations on it that can only be done in edit mode (like define a cluster). The idea being that if someone gave me on of these files, I could use this tool to build the cluster and then in a second pass, use that cluster to read the file. I suppose this question is not far removed from the past conversations about VI scripting, but at least this is only a subset of that whole idea. Anyone know if this is possible?

Interpretation of TypeDesc Property in Front Panel Control Reference.
Hello I am doing a little research on references to front Panel Items. If you get an array of references to the controls (and Indicators) on the front panel you can get their label text out rather easily. The value however is held as a variant and can be extracted if you know the type. Preliminary testing indicates that the Type Desc property is an array of 16 bit integers. The second column seems related to the type of the control. 16417 is boolean 16394 is numeric double 16387 is numeric i32 16434 is Path 15432 is a string. I do not like compiler archaeology.

RE: Labview, Linux and databases
While ADO and ODBC are both Microsoft standards, ODBC is a de facto standard across most platforms. ODBC is a low level engine for accessing DB.

Ballbar Communication (SAGA) - Progressing :)
Thanks again for severals answers to my previous question. My problem was that, when I was using the Basic_Serial_Write_and_Read VI to communicate with the ballbar (serial port), I was getting an error about accessing the port. Then, with the answers I got, I ensured that MAX and Hyperterminal were closed and tried again. And I'm back to my first error about timeout. In MAX, I'm able to read data from the ballbar. When I send *IDN?\n I receive A12345 (its name), when I send *S?\n I get the anticipated data from the ballbar. But, when I try to do exactly the same in Labview, I get timeout error (or access error if MAX isn't closed). So I'm still trying to figure out why I get this time error. I've checked all the properties (baud rate, bytes to read, ..) and even if I make the same procedure as in MAX, I get this error. I'm a bit confused about why there's a difference between MAX procedure and Labview, so if someone has an idea, I'd appreciate it a lot. Thanks again for helping me solving my problem.
Re: DAQ counter output
Hi Thorsten24, which developement enviroment do you use? LabVIEW, LabWindows/CVI or Measurement Studio? Which version? Generally the assistant locks your system for only one DAQ-application. If you want to do something else meanwhile (e.g. parallel pulsetrain generation and analog input) you have to program it by yourself using DAQmx without the assistant. You can use the EXAMPLE FINDER to search suited examples for your needs. Take a look in the following folders: DAQmx/counter/generate pulse DAQmx/synchronization/multi-function Norbert B. NI Germany

Luca has a great suggestion. I took a quick look at the user manual for the 8648 series and it appears that you should have no problem using this driver with the 8648D. You may have to set ID Query to False in the Initialize VI.

RE: Interpretation of TypeDesc Property in Front Panel Control Reference.
Yes, the OpenG solution using the ClassID property is nice however you can also use the ClassName property. This will give you a plain english word describing the class. You can then feed this into a case structure as a string. It will only take a few minutes to figure out the class labels. If you are curious and want to dig deeper into Type Descriptors.

Re: VIServer and TCP
Does anyone know if I can use the same port number for my VIServer and a separate TCP connection (established via listen function)?? In general, no. The port number is the mechanism for the operating system to decide what software will handle a specific packet of incoming TCP/IP traffic. In other words, its the sorting mechanism. To avoid confusion, you should use a different port number.
Re: extfunc.cpp
There is no telling. I suspect you got this from a message in LabVIEW. I recommend chosing to send the error message to NI with the automated submissions. Chances are the error is random an there is nothing they will be able to do. Occassionally the errors are systematic with LabVIEW and they will have a resolution.
Re: Ballbar Communication (SAGA) - Progressing :)
In your string control where you enter the command, do you have \ Codes Display turned on? This is set by right clicking on the control. If you don't, you are not sending the control character but the strings \ and n. You could also set the VISA serial port properties to automatically send a termination character with each write or do a append string with your command and use the line feed constant on the string palette.

RE: ActiveX server in Labview
Title: RE: ActiveX server in Labview Unfortunately that's what I was expecting but I thought I would ask. For all it's strengths, the biggest weakness I've encountered in Labview seems to be with it's interface to other applications (on Windows). I'm sure this is partly due to it's platform independent nature since DLLs and ActiveX interfaces don't exist on non Windows machines. It's too bad because we could do some really cool things if they were better supported. I've also, in the past, had the need to register a callback function in a DLL (non activeX) but the concept of passing a pointer to a LV function doesn't exist. Wrapper DLLs, created using other compilers, are often needed to solve these issues. This tends to undermine the use of LV in the first place. I think we should include these enhancements in our LabVIEW wish list (hope you are listening Mr McKaskle). Perhaps NI developers can somehow tie activex into the event structure so a programmer can define events that correspond to activeX methods. Both the event and method would be created by the programmer. Also, allow for pointer to function capabilities for DLL callbacks. Anyway, thanks Michael A and Rolf K for your responses.

It is a Windows thing--but then ODBC is too. The point is that all you need is some sort of support for the selected OS. If necessary you can hide the differences in I/O between platforms in low-level VIs.

George, Yes this is possible, check out this thread on LAVA: http://forums.lavausergroup.org/index.php?showtopic=307 It has an example of dynamic generation of refnum (but it can be cluster). Note: The target VI (where you generate the cluster) has to be idle (not running). PJM"George Gatling (Contractor)" [EMAIL PROTECTED] wrote: I have an file format that lets me store nearly arbitrary (though not nested) clusters in tabular (and binary) form... each column is an element from the cluster, and each row is a complete cluster... so the whole table is basically a cluster array. There is header information in this file that completely describes the layout of the binary table, and this header information is derived from the 'type string' information provided for each labview data type. So, by reading this header information, I can completely describe the type of the cluster represented by the binary table.Now, I know I have some runtime limitations, but my question is aimed at the editing environment. Is there a way to build a cluster using the VI server? I imagine the executing VI creating a new VI and then performing operations on it that can only be done in edit mode (like define a cluster). The idea being that if someone gave me on of these files, I could use this tool to build the cluster and then in a second pass, use that cluster to read the file.I suppose this question is not far removed from the past conversations about VI scripting, but at least this is only a subset of that whole idea.

Re: VISA Write Timeout
In a similar way, if your instrument doesn't recognize the serial Break, you might try toggling the RTS and DTR lines. That's one of the main things VISA does when you close and reopen the port, and many older devices will see those 2 lines as a way of indicating that the connection is alive - assuming you're not using hardware flow control.

Re: smooth a single looping step for a biped robot
Just butting in here with a fairly simple idea that doesn't get into any filtering theory. Basically, you would just do a weighted average of the data points near the cycle boundary, and let the weighting factor ramp from 0 to 100% over the set of smoothed points. For example: suppose bn/b is the number of points in the cycle so that (ideally) data(0) = data(n) = data(2n)... let smoothed(0) = 0.50*raw(0) + 0.50*raw(n) smoothed(1) = 0.55*raw(1) + 0.45*raw(n-1) smoothed(2) = 0.60*raw(2) + 0.40*raw(n-2) ... or generally, for -10 = j = +10 smoothed(j) = (0.50+0.05*j)*raw(j) + (0.50-0.05*j)*raw(n-j) smoothed(n-j) = (0.50+0.05*j)*raw(n-j) + (0.50-0.05*j)*raw(j) Do you think something like this would produce sufficiently smooth blending?
system exec question
I'm really looking for an unzip VI, but since I'm running an ancient (5.0.1) version of labview, I'm guessing that the SystemExec vi is the way to go (Open G unzipper seems to require a more modern version of LabView). So now to my question... Is there a way, in the 5.0.1 version of SystemExec, to capture the output of the command other than making a redirection part of the command? Is it syncronous or asynchronous? Thanks! Bruce -- +---+---+ Bruce Bowler| Sex is the worst reason to marry or divorce. - Dr. 1.207.633.9600 | Albert Ellis [EMAIL PROTECTED] | +---+---+
Re: Odd behavior in Build Text Express VI in 7.1
Ed, We re-worked the Build Text VI for 7.1 to address some issues which is why it behaves different. What you are seeing is that you are trying to configure a non defined variable. When you type in the variable name, the VI applies the default settings to that variable, until you change them. So on the first variable this causes the settings you had set to be lost. However once the variable is defined the settings should follow that variable. I have made a report of this so that it can be looked into. Evan National Instruments

RE: Dealing with large file
Depending upon the format you are saving the data, like for example *.csv format, you can determine the number of lines in your file and then either save that section in a separate CSV file and tell XL to open that one in the first spreadsheet, you can keep doing this for every quantity(65500) of rows. But this is just a suggestion and depends upon the data types you are using. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, May 17, 2004 12:46 PM To: [EMAIL PROTECTED] Subject: Dealing with large file Can any one help me please?

get cluster
I have gotten a main VI that will pull in several sub-VI's to do some testing. I want the main VI to not just pull in the cluster information that the sub-VI has, but also what kind of information. For example, in one of my sub-VI's, I have a cluster which contains age, height, weight, and size. I want my main VI to automatically create the same cluster after open the sub-VI. In another word, the main VI will make an exact copy of the cluster in the sub-VI and put this cluster in its front panel. Do you know how to do this? Thanks.
Re: Can a labview executable program be converted back?
No. What you're asking for is the equivalent of editing Word, Excel, or any other executable. In theory, you can use a disassembler to view and modify the exe but you had better be extremely proficient in assembly code and the details of the LabVIEW compiler. With some older versions of LabVIEW, there was the option to create an executable without removing the diagram. On the off chance that you might have one of these, change the exe extension to llb and see if you can open anything.

import entire cluster at run-time
Hey all, We're trying to create a user interface that runs another stand-alone sub-vi. My vision is to grab some sort of input cluster from the sub-vi, display it in the user interface VI, and choose options from it. Right now, we're able to grab the data from that sub-vi's input cluster via a Reference, but the input data is not important. We just want the form of the input cluster to appear in the user interface VI. By just copying the input cluster directly to the user interface VI, this process is pretty easy. The catch is when the sub-VI changes, the user interface VI must be changed manually. Any suggestions? Thnx, allen
Re: import entire cluster at run-time
Hi, If you strictly type def your cluster (customize controlStrictly type defsave), the user interface will reflect any changes you make to the cluster. Actually, any places in your code where you use that cluster will reflect the changes (as long as you are using the strictly type def cluster).

Re: Why does my computer, running Windows 2000 and LabVIEW 6.0.2...
Although I'm not sure what specifically is causing the problem, I can surmise that you're experiencing a 'feature' in Windows 2000/XP. By default in these OS's, if there is a major system crash the computer will automatically reboot. You can change this by right clicking My Computer-properties-advanced-start up and recovery and uncheck the 'Automatically Reboot' box. Now when your system crashes you will likely see a classic Blue Screen of Death.
Re: Saving data in remote panel
The following is an excerpt from the Labview 7.0 User Manual, page 18-15 (chapter on remote panel limitations): Additionally, some VIs might not work exactly the same way from a remote computer as they do when run locally. ActiveX controls embedded on a front panel do not display on a remote client because they draw and operate almost completely independent of LabVIEW. If a VI presents the standard file dialog box, the controller receives an error because you cannot browse a file system remotely. Also, the browse button of a path control is disabled in remote panels. So I think it is the file dialog box and not the saving of the file which causes the problem in your case. In fact, I successfully use in one of my programs a 'Save to file' procedure, but the filename and directory are generated automatically and no dialog is used. A solution in your case could be to read the file/directory info programmatically in the VI and present it to the (remote) user within a labview (and not OS) dialog box. Admittedly, a quite complex solution... If anybody else knows a simpler solution, I am also interested int it... -Franz

Re: Error kernel.cpp line 144 on exiting an EXE
Hello Mike! I have searched our internal databases here, and we do not have any documentation relating to the kernel.cpp error line 144. When you get the TCP read errors, do you get error codes associated with those errors, or do your applications just freeze? Also, does this just happen when you are in the run-time (EXE) environment? As of LabVIEW 7.0, there is an error report that is generated when LabVIEW experiences a *.cpp crash, and there are no reports of this line number in our databases, so it is possible that whatever problem exists in your application has been investigated and fixed in the later versions of LabVIEW. If you have any more information I would be happy to look into it! Regards, Colin C. Applications Engineering National Instruments
Re: How to group spectral peaks into families? K-Means doesn't do a good job.
Hi, I'm not familiar with k-Means but I have some tips that you could use: The Sound and vibration toolset and the Signal processing toolset offer a Zoom FFT tool that you can use to extract more detailed information on frequency range with the same number of points. It uses a donw-conversion algorithm to step down the data and the perform an FFT. a better prescition on the peaks can help you classif better into families. I'm may be completely showing my ignorance of you application here, but you could create an array of the peaks and perform a histogram where your main peaks could determine the center of each bin in the histogram. Another idea would be to do some averaging over your FFT data to create a smoother curve with peaks where the families would be. Just my 2 cents! Juan Carlos N.I. FYI: LabVIEW's Order Analysis Toolset has tools for order tracking and machine monitoring.
