• Use creation to read alternating channels and data

  I have a csv file that I am trying to create a use. The help file says that if I specify a line in the form of data, then all subsequent lines must also be given.

  The first line of my file is a header parameter names of test. I would like these are the names of channel for the actual data (parameter values) that follow on the next line.

  Then I have a blank line, then a line with my main data channel names. The following lines are then the main actual data.

  I'm sure I need a VBScript to do this, but am a little to get something that works based on examples that I found on the shelf.

  I want to bring in the header data in the data portal so that I can put some of them together with graphs in my reports.

  I have attached a sample data file. Also, I would generally ignore some of the columns of data (in this case, columns 3 to 10)

  Thanks for your suggestions!

  Hi Greg_Gran-

  I have attached a personalized use which will be structured according to your posted example files and will ignore the third to the tenth data channels.

  To use the use, simply unzip the cover record attached to your hard drive.  Double-click the *.uri file that is included to register for use with your computer.  Once you get the registration successful dialog box, you will be able to load your data files.  Because CSV is a format of generic file with many variations, you may need to push the priority of this particular use for the *. "" "Extension CSV through DIAdem NAVIGATOR" settings "My DataFinder ' configure ' menu File Extensions so that this use is always used instead of the other *. DataPlugins CSV.

  I didn't know if you wanted to ignore the third to the tenth of all columns of data or from time to time, so I built a small hook in the use that will allow you to adjust the 'package' of ignored channels (e.g.: 3-10, 1-5, 21-30).  To change the range of the use know when loading:

  1. Select the NAVIGATOR tiara.
  
  
  2. "" "Select Settings ' Options ' Extensions ' DataPlugins.
  
  
  3. Right-click the use of Greg_Gran_CSV, and then select Edit the Script.
  
  
  4. In line 5 of the use, the variable "Ignore" is defined as a one-dimensional two values (3 and 10) table.  These are the upper and lower values defining the range of the data channels to ignore.  To load all the data, change the value (or both) - 1.
  
  
  5. Save the use.

  As I had only a single file to test with, I can't guarantee that there will be problems with your other files - let me know if you encounter any problems or if you have any other questions.

• Channel of String conversion to the data channel

  I have a problem I tried to accomplish through a. The URI of the file but can seem to make it work good for me.  I have an original data channel are in TEXT format and the data in the channel are the phone number in the format 6667779999 or 4343. Can someone help me with a suggestion of script to convert this. Most of my ATTEMPTS end with a 66.67779e5.  Can be simple but I can just figure it out.

  Thank you J

  Hello J,

  A number such as 66.6778888e5 can be shown as 6667778888 in a DISPLAY box or table or text REPORT or a axis of REPORT graph by using the display correct format string - in this case "d".  Where do you 6667778888 number appears like this in DIAdem, exactly?  If you want to see in a BULLETIN Board, you will need to choose the option button 'Selected channels' first in the configuration dialog box, and only then will you be able to choose a format string to display such as "d" for this column.

• PXI-5122 and PXI-6259 read 2 channels simultaneously

  There is a single PXI-5122 digitizer card and a PXI-6259 DAQ card in our PXI system, we use Labview and TestStand (model Batch) to test the multiplication Board simultaneously, sometimes up to 8 boards are tested. We have some problems, such as the results of the tests is not reliable and sometimes blocking of Labview. Everything works fine when test single board. Thus, we feel that multiply causing this problem of acquisition of string data. It's great, if someone has the same problem and we can share the knowledge. My question is as follows:

  1. If two channels have been configured, read the two channel simultaneous cause blocking of the system or data damaged?

  "lu niScope WDT.vi" is reentrant, we can use two Subvi to call the "niScope Read WDT.vi' access the two channels simultaneously.

  2. If we set up a channel in another channel is reading the data, this situation will cause the search system or corrupt data.

  Concerning

  Samuel

  Hi Samuel,.

  You shouldn't have any difficulty to read several channels on your 5122 or between your 5122 and your 6259. You receive an error message when your test is blocked? What happens when your test is not reliable? Are you incorrect data and if so what is the data vs expected data acquired? You should be able to set both your channels in a single task, which would be using a read niScope WDT.vi to be used by the device. You are working from example or have you developed your own code? What version of the driver NOR Scope and NI-DAQmx driver do you use? You can find the driver version number in the measurement and Automation Explorer under the software section.

  What kind of test are you running? Your PXI chassis is controlled by a computer or by an on-board controller? Evolution of the rate of acquisition has an effect on your program?

• Read specific channels of an existing PDM file

  Dear users of Lab View,

  I would like to ask for help using the PDM read Vi to read specific channels in existing TDMS files.  I know to use the "contents of list TDMS" vi to that group names and channel list, but I don't know how then use this information to read identified specific channels.

  the problem, I'm trying to work around is to read a file of PDM with data from two channels, each with a different amount of data taken at different speeds. I would like to read a block of data from a single channel.  However, this data block contains more elements than the other channel. So, end of file error almost everytime I meet because the read PDM Vi tries to read this block of data for each channel.

  How can I specify the channel for the PDM read VI?  I tried to create a constant and fix them on the node "channel name" on the PDM read VI, but it gave an error.  I guess I don't know how to format.

  is attached the VI I'm trying to implement

  A sample file is too large to attach.

  Thanks for the tips

  I think that the problem may be that you close the TDMS of origin reference in each iteration of the loop, try to move outside as shown in the snippet.

  Note that I don't really went through the logic for the rest of your code.

• Function to count the total number of data channels

  I know that I had stumbled on a tiara function that returns the number of data in all of my data channels.  I can't seem to find the thread where I had seen it.  I'm looking to replace a script a long time user with this simple function in my future coding.

  Thank you!

  Hi CrshTstr,

  I actually still use GlobUsedChn for that.  In more recent versions of DIAdem, you can use commads as GroupChnCount() or Data.Root.ChannelGroups (1). Channels.Count to return the number of channels in a particular group.  But regardless of which group the channels are in the GlobUsedChn variable always returns the total number of channels currently on the data portal.

• Reading data SCXI-1600

  Hi Experts,

  I'm new to this interface SCXI. Kindly help me in the framework

  I'm developing an application that will be using the SCXI-1125 and SCXI-1600 controller module. In the application, I want to allow the user to configure the different tasks in the front panel.

  What are the necessary controls in the front panel to allow the user to configure the task

  How to read the data of the SCXI-1600,

  How to differentiate the eight channel data from 1125 SCXI thro SCXI-1600

  Thanks in advance

  True, you can't simulate the SCXI-1600. This means that you will not be able to run your code without the hardware. For simulation purposes, you can, however, use another device that would work in the same way for the SCXI-1600 in terms of triggering, resolution and the frequency of sampling.

  In regard to programming, would use it DAQmx as I'd mentioned. There is no specific examples for the SCXI-1600, but you really do not need them. The SCXI-1600 is basically a data acquisition module, which is located in a SCXI format with a USB connection. Your software is concerned, you will use DAQmx to read data from it. Then, take a look at DAQmx examples as data on data acquisition devices.

  Your task will define how many channels you will read. Since you are reading a mixture of measures (temperature, pressure and tension may be simple), you will need to decide whether to create separate tasks for each of these measures that are configured to be specific to this type of measure, or to create a task that reads simply all channels not adjusted values (i.e. raw tensions) and then put you in the scale of values in your code. If you open the example Finder and navigate through the input and output hardware tree-> DAQmx-> Analog measures you will see different categories for types of measure. Many of them have graphics.

  If you have not already done so, you can start here: http://zone.ni.com/devzone/cda/tut/p/id/3116

• Equium A200-1V0: DVD-RAM UJ-850 s does not read data discs

  My laptop seems to have decided to stop reading data disks.
  However, there is no problem with the audio CD, but when I insert a data disc such as the software considers the disk is empty and try to format the drive.
  I searched internet day for solutions and tried without success to the following:

• "Could not read data" when you try to print from Android

  Hello. I have a printer HP Officejet 6700 Premium, which is connected via ePrint/HP connected to my Google account so that I can print from my Google devices (Cloud Print). While this works very well when printing from my laptop (29 Chrome on Ubuntu 13.04), it does not when printing my Nexus 10 (Android 4.3) or my Galaxy Nexus (CyanogenMod 10.1.3). I tried printing both outside and inside the network on which the printer is on, but whenever I get "could not read data" in the Cloud Print dialog box. It seems that Cloud Print knows that the printer exists, since it is on the list, but it cannot communicate with the printer. Any way to solve this problem? He's good enough additional features only on my previous printer, who died of old age.

  It seems to me that the question is in fact Cloud Print related. Here is the support page: https://support.google.com/cloudprint/?rd=1

  Remember that Google Cloud Print is still in beta phase. Good luck tomslominski.

• HP Pavilion X 2: HP Pavilion XP cannot read data from USB DVDs

  We bought a HP 10-ND200ND (HP pavilion X 2) in the Mediamarkt and tried to install Microsoft Office from a DVD via a DVD USB Samsung player.  This was not possible. According to Support Mediamarkt this product is a Tablet and so cannot read data DVD´s. Only General to play music. To buy a laptop computer for this application. The operating system is Windows 10 (32 bit). Is that correct. Please advice.

  Hi Banhien, the cause is known. I have seen other comments on the HP forum and concluded that the reader needs more power than is available through the USB connector of. I added a hub that can provide power to its connectors USB, HP X 2, by car and the problem has been resolved! It was noted that the mini USB is also more powerful and with the type of adapter USB USB C it might also work, but I did not test this, because I do not have such an adapter. It's odd that such a mini can provide more power. It is surprising that the HP Pavilion X 2 does not have a powerful USB. But the problem is solved. Thanks for your response! Best regards, wiely
