• How to pass data to the tables according to the value of the first 4 digits of 7 strings of numbers

  I want to sort incoming data, in several bays based only on the first 4 digits of each string.

  For example, a hexadecimal string may be 41322033333533 which is A1 3353.

  A1 is a sensor. particularly, and I want to send all data from the A1 to a table. I have 8 sensors data and want to send the data to separate the bays of sensor. My sensor names are A1, A2, A3, T1, T2, T3, W1

  I will use a structure of the matter, for loop and a comparison of '=' for the data. However, I want to only compare the first 4 digits of the string and I can't find an operator for this. Any advice on how to proceed would be appreciated.

• Reports on the string data when it crashes more than digital data

  It is an interesting situation for me. My apologies to simplify the introduction to the problem.
  
  It's easy when I met data from the table, a table, you have your descriptive data (Look up table)... Name of the product, the Transaction name,..., etc and you have a related table with the digital data in it (Table of facts),..., sales, cost, margin,... etc.
  
  Of course when the table with digital data in it breaks down further than the table with descriptive data. The solution is simple. Simply summarize you the data grouping in the descriptive table of digital data.
  
  ... Ok. Sorry about all this. Now, here's my problem...
  
  I have a situation where my table (get) descriptive data breaks down further than digital data in my table of facts. I know there is no way to summarize the data of type string, but I need a way to report the values in my eyes to the top of the table on the same line as the digital data cell associated with TWO or MORE look for rows in the table.
  
  I bet that this is not the first time that it has produced in the history of the RDBMS, so I think there must be a methodology out there somewhere to handle this situation.
  
  I think the final result will be something like; concatenate the descriptive data in the description cell that will be reported next to the digital data on the same line. I just need to know what the official solution, when it exists. There must be. Or at least a clever work around...
  
  Does anyone know what it is or how to handle this? Even more, is there a formal name for this kind of situation?
  
  Thanks in advance!
  

• Is there an easy way to get a Date/time string seconds?

  I have 2 strings of the format depending on whether I would like to convert in seconds (since 1900). I need this value to set the t0 in a field.

  Date: ' 30/06/2014 '.

  "Time: '16:06 ' 08."

  Is there a CVI function that will do this conversion for me? If not, is there an easy way to do it?

  Thank you!

  This code should do what you want:

  
  
  
  static time_t  calt;
  
  struct Shared  tm tm;
  
  public static char    msg [64];
  
  public static int     AA, mm, DD, hh, mn ss;
  
  strcpy (msg, ' 2014/06/30 16:06:08 ');
  Extract the date/time string component
  
  Scan (msg, "%d [x] %d [x] %d [x] %d [x] [x] %d %d", & mm, dd, and yy, & hh, & mn, &ss);)
  Transfer to a struct tm components
  
  TM.tm_hour = hh;
  
  TM.tm_min  = mn;
  
  TM.tm_sec  = ss;
  
  TM.tm_year = yy - 1900;

• DAQ USB 6363 - generate digital data series through the single DIO line

  Hello

  I'm new with Labview, currently, I bought NI DAQ USB 6363 for generating control signals and signals analog accquire. I would like to send digital data series through one of the digital IOs with throughput of 30 kbps. Please see the attachment for the data frame. Could someone comment the feasibility of this? Y at - it codes for the example that I can refer to? Most of the examples I've looked at so far deals to generate several line instead of 1 single line. How can I achieve this?

  Thank you

  Diem

  Hey diem.

  After looking on your code, I understand what you were trying to do. Here's how I'd do. Usually we do not write code to clients, but you peaked my curiosity of! I hope this helps. Good luck!

• Maximize the continuous digital data recording rate

  I'm trying to record digital data clocked outside large amounts quickly.  The data is only for post-processing.  What is the best way to get data from the port on the hard drive at the fastest possible pace?

  I connect using a PCIe 6537 B.  I log on 4, ports of 8 bits to 40,92 Mhz, so a rate of ~ 160MBytes per second.  I have two designs I've tried so far (a producer-consumer architecture and a DAQ.mx configure logging design).  Both models work if I connect only on two ports (effectively halfing the necessary flow) but fail to the width of 32 bits.

  My producer consumer architecture fails after about 30 seconds of recording successful message

  Error - 200613: Acquisition was stopped to avoid a crushing of the input buffer.

  My other DAQ.mx configures logging design fails quickly (~ 1 sec) with

  200361 error: Overflow memory on-board

  .

  I could be set it up incorrectly.  As I said, it works with 16-bit data width.  I don't know if the increase in the width of the data directly is the problem or if the increased flow to fail.

  I use this on a 3 GB ram windows xp using labview in 2012.  I have attached the vi of my two attempts and a picture of the DAQ.mx set the logging design.

  Well, I'd suggest the integrated PDM recording method would probably be you give best results, assuming that it works at all.  This record type opens a DMA channel of the material on the hard drive so it should not produce copies of useless data, which would probably be a producer consumer loop.

  I never tried logging TDMS without reading the data, a Read DAQmx should be used in the loop?  Your file contains TDMS data?

  The challenge of your hard drive?  It is a flat disk of laptop?  I recommend you test on a SSD, if possible, just to see.

  There are also properties to open up to a size of memory buffer.

  Start with one of the logging TDMS basic examples delivered with LabVIEW and work your way up from there.

• How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?

  I want to integrate the ANSI C sample program ReadDigPort - ExtClk.c in my own big package.

  I want to use the internal clock of the BNC NI USB-6259 (.. 80 kHz 120 kHz).

  In the document:
  High speed M: Series Multifunction DAQ for USB - 16-bit, up to 1.25 MECH built-in BNC connectivity. / s,.
  is written:
  Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
  The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

  How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?
  With what other subsystem on the device can generate a source of the clock? How?

  It is possible to set a clock on an internal counter (for example ' Dev1/ctr0"):
  Creates channels to generate digital impulses that define the freq and dutyCycle and adds the channel of the task that you specify with taskHandle.
  DAQmxCreateCOPulseChanFreq (taskHandle, "Dev1/ctr0" units, clockName, idleState,
  initialDelay, freq, the duty cycle); works

  But it is not possible to drive this internal clock to a terminal (for example "/ PFI0/Dev1"):
  DAQmxErrChk (DAQmxCreateCOPulseChanFreq (taskHandle, "/ PFI0/Dev1", clockName, units, idleState, '))
  initialDelay, freq, the duty cycle); does not work: error DAQmx: measurements: type I/O of the physical channel does not match the type of I/O required for the virtual channel you create. Name of the physical channel: PFI0. Name of the virtual channel: clock

  The sample clock source can be derived from an external terminal (for example "/ PFI0/Dev1"):
  Sets the source of the sample clock, the sample clock rate and the number of samples to acquire or generate.
  DAQmxCfgSampClkTiming (taskHandle, "/ PFI0/Dev1", maximumExpectedSamplingRate, DAQmx_Val_Rising, ")
  DAQmx_Val_ContSamps, bufferSize); works. Acquire or generate samples until you stop the task

  But it is not possible to derive the internal counter of the clock (for example ' Dev1/ctr0"):
  DAQmxCfgSampClkTiming (taskHandle, "Dev1/ctr0", maximumExpectedSamplingRate, DAQmx_Val_Rising,
  DAQmx_Val_ContSamps, bufferSize); does not work. Error: Acquire or generate samples until you stop the task: make sure that the name of the terminal is valid for the specified device. See Measurement & Automation explore valid names of terminals. Property: Property of DAQmx_SampClk_Src: DAQmx_SampClk_ActiveEdgeSource device: Terminal Source Dev1: Dev1/ctr0

  Hi datafriend,

  using what it says is correct:

  Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
  The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

  This means that if you do not use an external signal as clock you can use the sample clock to HAVE it on board or at the output of the internal counter.

  There are also 2 ANSI C examples in this regard:

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/4485

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/4488

  So in both cases you have to use a fictitious task you need only for the generation of the internal clock (HAVE or CTR)

• accuracy of digital data from LabVIEW

  Hello!

  I have a question about the accuracy of data, Labview, is perhaps a silly question, but it drives me crazy.

  If I use a digital constant and I put for example 1 (I mean 1E-6), it looks like 1E-6 but I found that it is not really 1E-6, actually if I raise the precision and I use 17 digits, 1E-6-9, 9999999999999996E-7.

  Could someone explain to me what is happening for digital data?

  Thank you

  It is one of the most frequently asked questions ever.

  The trick is in how computers represent floating point value. I remember a lot of right answers already given in the forum, but I am not able to find the most comprehensive and clearest.

  For example, one of the answers is here.

• How can I determine what digital data was issued last with the regeneration?

  Is there a way to determine the last digital data output if you are running a quick revival and regeneration?  Right now I use a digital channel not used by the channel with the same clock that I use for other data capture. It works very well and I know that the data I receive are correct, but there is something wrong with burning a channel for that. The data I am regenerating changes several times during the trial for counting samples to determine where I was in the buffer would make my code more complex and the chances of a mistake to increase.

  I have a mixture of material that I use for a cDAQ-9172, a box of series M and a PXI-1033 USB.

  Hello Tom,

  There is absolutely something wrong with having to use one of your channels to monitor what you're out, however, it's the best we can right now.  The problem is, when you set a buffer until the release, the access card to this memory stream location it will regulate.  It's speed leaving and overall card design.  There is no way back on the material for do what you are looking for and no software to interact directly with the location of the buffer.

• date/time string

  Hello

  I would like to retrieve information about the last use (date and time) of a user, but I don't know how.

  In my program, the user enters the name of the person they are looking for. The person sought may be used multiple times in a day, or even in the software of the year Labtech or Adam. I would like to retrieve the date and time of the last use of the program for the person.

  I try with the "format date / Time string" but it returns me the same date of my tests.

  Do you have an example

  Thank you

• date/time string tabs

  Hello!

  I have a problem with the date/time string format VI. I would like to define the date and time with a tab to see the date and time in different columns so when I opened the data written in excellent... but I can´t! I ve tried with \t in the bar code backslash... (% d/%b\t%H:%M:%S%2u), also with concatenate strings with a constant of the tab in the middle... (as illustrated in attached piece) but the extent of my file the tab written as \09 (14/May\0911:00:20.25) s. The strange thing is that when I use \s (space code) it works fine... Why does only not with the tabs?

  Thank you very much for your answers!

  Hi Mia,.

  as I have LV8 + at the moment I can't dig deep - can someone else check this Express VI (stay away from them )

  You can use simple 'write in the text file' calls instead, just use 'picture to a worksheet string' on your data. That's what I'd do... (Express screws are nice start using LabView or quickly write code running - but they hide all the interesting stuff and won't provide any flexibility for special needs!) And they always need conversion into "dynamic data", which also hides the user's information. Did I mention I don't like screws Express?)

• What is Western Digital Data LifeGuard Diagnostics?

  Friends-

  I noted in my start/programs, a new piece of software has been added to the list, and I needed to install it. It is called Western Digital Data LifeGuard Diagnostics. I don't know where it comes from, so I guess it's an auto-update from Ms. The problem is that when I Googled it and it raised online on Microsoft.com, all references were too opaque for me to grasp what, exactly, does it.

  Its own pages of support, he said that "it is a version of Windows Data LifeGuard Diagnostics. It will test the internal and external WD drives. In additional, it can provide you with the model and series of WD drives attached to the system. "Huh? Why would I want or need this information?

  I am wary of what he is and does (quite thin on explanation there), but there seems to be so many things about it that I am comfortable, considering that it is not a scam/spam. The problem is, where he comes and what benefit can it give me? Sorry if I am too a novice on this, but I have never heard of him.

  Any information would be welcome. Thank you.

  Hello MDBoy,

  From an internet search, Western Digital Data LifeGuard Diagnostics is a program that performs hard drive diagnostics.

  The utility can make identification of the drive, diagnostics and repairs on a Western Digital FireWire, USB or EIDE drive. In addition, it can provide you the series and model of the player numbers.

  In addition, there is a feature called write zeros: this option can be used to clear the operating systems and file systems.

  So if you do not install this software, I would say you uninstall and remove this diagnostic software. You can go into Control Panel, click programs and features. Western Digital Data LifeGuard Diagnostics must be there. There is a column it installed on. This will give you the date, that the software has been installed, then it can give you a clue.

  Thank you

• How can I search for files in a range of digital data

  Is there a way to specify a range of digital data in Windows 7 search for example File1 through deposer10 included

  Thank you

  So you're saying that file names could be, for example, hotdog4.txt for hotdog15.txt?  Well, you can look for in an orderly series, numerically and alphabetically, with two periods between the first and the last item, as in name:hotdog4.txt... hotdog15.txt

  Interestingly, Windows by default notice when the names correspond to a digital frame and so will sort hotdog4 to hotdog10 and so on, despite 4 being a number greater than 1 Prime figure 10.  I found a reference to this topic (but do not disable anything probably, just for the pleasure of reading):
