• Get the Max values and average of the different cycles in the single channel

  Hello

  I'm trying to get the Max values and average of the single channel that has different cycles it contains. I tried to use commands such as Chnclasspeak3 and chnpeakfind, but they were not useful for me. What I need is the Max values and average of the different cycles numbers saved in the data channel.

  Exampld if the string contains 5 numbers of repetitive cycles, then we must find the maximum values and the average of these 5 cycles in the single channel. Attached reference data. This is the .raw file and I have the plugin for it to use in diadem 11.1.

  Kind regards

  Hello, Ignatius,.

  Sorry, it took some time to provide a replacement based on the script for the function. Please take a look at the attached script. I changed the script to use my function if the tiara-version is less than 12. My script function is not as fast and more stable than the implementation of tiara, but for now, it does the job

• flatten channel adds the length of the string

  Hi all

  I flatten a cluster chain help to flatten to string.vi. The cluster contains strings and arrays. The flattened string contains the length of the string that is appended to the string.

  So if I have a cluster with only 1 string and a value = "LabVIEW". the flattened string would be "0007LabVIEW". Flatten channel vi has a Boolean entry "add string or array of size? even if I set the Boolean value false, it always adds the length of the string. Is this a bug?

  I think that if you read the detailed help to flatten it to string function you will see this is not a bug.  That boolean applies only to top-level data, once put you something in a cluster or array, the Paris are open.

• Detecting by programming error of channel type (so-called task invalid when I transmit channel in the reference entry)

  Hi all

  I am having some problems of data collection with a VI that I put together using LabVIEW 2010 and DAQmx 9.5. My DAQ hardware is an SMU-6341 in a chassis SMU-1071. I have a single VI which runs through all the tasks and controls that are channels in each task. Channels are then moved into a knot of channel property to check the type of channel. It allows me to adjust program which DAQmx read that I use to read data from the buffer.

  I get error code-200428 stating that the task I'm passing in the channel property node is not valid. It then gives me the CHANNEL name that the task is not valid. Am I assuming I can switch from channel at the entrance to a property DAQmx node reference? I know that the task and the channel of the task are configured correctly because I can see the voltage on the digital output terminal.

  Any help with this would be greatly appreciated.

  Best regards

  Ryan

  Types of channel properties are weird.

  You must connect the task in the upper left entry of the channel property node, not the channel.

  Then choose the 'Active channel' property and add another property to the node which is chanType.  Son of your channel in the first and get the chantype of the second property.

  

• I have a DAQ Assistant configured to read several channels at the same time. When I have a graphical indicator of wire to the output, I see all my signals mixed together. How I divided them into separate signals?

  I have a DAQ Assistant configured to read 2 channels at the same time. When I have a graphical indicator of wire to the output, I see 2 signals mixed together. How I divided them into separate signals?

  When I wire any type of indicator, it is show that a release of a single channel.

  I want 2 indicators showing 2 different signals as expected from 2 channels configured. How to do this?

  I tried to use split signal but it end by showing that 1 out of 1 signal two indicators.

  Thanks in advance.

  Yes you are right. I tried, but I don't have the result.

  I just find the path. When we launch the split signal, we should expand it (split signal icon) by top, not the bottom. It took me a while to understand this.

  Thank you

• Try to uninstall build Munki 3.1, does not work and leaves several entries in the registry

  When I try to remove build Munki 3.1 a few days ago. However, direct the directory uninstallation fails generally as the Build Munki 3.1 leaves several entries in the registry of the computer. How should I do?

  * original title - how should I do? *

  Hi jacob,

  If the standard uninstall process is not working (as seems to be the case), then try to use the free Revo: http://www.revouninstaller.com/revo_uninstaller_free_download.html that often works when the usual process does a complete job.  I know for a fact that in advanced mode, there's a special process which deals expressly with clean up the leftovers of the program register.  Personally, I use Revo to uninstall everything that I want to uninstall (more with AV products special removal tools) because almost all normal uninstall process leaves something behind (I had to remove the remains on almost each uninstall I made using Revo) and this will keep my own system.

  If you have already uninstalled to the point that it does not appear as an option in Revo, then reinstall again and then uninstall with Revo in advanced mode and this time and that should do the trick.

  I hope this helps.

  Good luck!

• play several stereo channels on a single mono channel tia sal22

  Hello all

  I have a vi that creates multiple stereo audio signals
  in labview 8.6.1 and I would play all stereo channels on a single Mono channel
  is this possible?  I tried setting all the device ID's for the same thing, but a lot of clicks and POPs has occurred.  Basically, I'm playing and mix all the signals on a single mono channel at the same time.

  Please note that I would have each created signal played on
  the mono channel at the same time.

  Just add the berries if they have the same length. Use the standard add function (as in 2 + 2 = 4). The tables are then added to each index is added

• Several links in the single column

  Hello

  I have a requirement to display several links in the single column.

  Example:

  Select emp_name emp #, total_days days, col3, col4 from table

  Here, I need to display a link beside the example of days

  If day > 100 then display "101 CH" where 101 days value and CH is the URL link which will open a popup page. I can't have another column for the link that we have already several columns. So I need a way to display the link with the value next to him. How can I achieve this?

  try to put it in the source of the region

  Select emp_name, emp #,.

  -case when days > 100 then days | " http://Google.com" target = "_blank" > popup' another to_char (days) end total_days, "

  col3, col4 from table;

  This should display "101 popup" when the days more than 100, no popup link on days<= 100="" e,g="" "99"="">

  and the value of the column total_days to the "Reporting Standard column" to allow html tags.

  Change the href attribute and formatting to meet your requirement

• [Flex entry for the c# string array type: string]

  Quick question, what would be the type of entry for Flex if the data on the web service type c# asp.net is an array of strings, string [], it seems to automatically detect as an ArrayCollection, but collection which isn't fair, so I suppose that table, but I would still like to confirm this.

  It was in fact collection arraycollection:------.
  the answer is:

   

  var _compEmp:ArrayCollection = new collection ArrayCollection (new Array ("Shaine Fisher"));

• Several channels with the launch of unique digital dashboard

  I have a simple vi where the two analog channels is read in and stored simultaneously in a file of lvm and plotted on a graph of a waveform. I need a numerical advantage to post trigger data for both channels.

  I can get this vi to work with one analog channel and the onset of digital edge very well.

  When I remove the digital edge trigger, I can get the vi to work with two analog channels. The two signals of ground on a waveform graph and record nicely in the file of lvm.

  The question is how do I set up the digital triggering (see table).  The program never enters the while loop. Where I'm going wrong?

  Chassis: cDAQ-9172

  Analog card: NI 9205 (Source PFI0 the shutter button)

• The use of DAQmxWriteDigitalScalarU32 for write channels share the same ports?

  Hello

  I have a USB-6509 and NOR-DAQmx installed 15.5.1. Using the ANSI c api.

  Is it possible to create several independent channels that use different lines of the same port?

  DAQmxCreateTask("",&th1)

  DAQmxCreateDOChan(th1,"Dev1/line0:4","",DAQmx_Val_ChanForAllLines)

  DAQmxStartTask (th1)

  DAQmxCreateTask("",&th2)

  DAQmxCreateDOChan(th2,"Dev1/line5:9","",DAQmx_Val_ChanForAllLines)

  DAQmxStartTask (th2)

  ....

  and repeat for the following strings:

  Dev1 / line0:4
  Dev1 / line5:9
  Dev1 / line10:14
  Dev1 / line15:19
  Dev1 / line24:28
  Dev1 / line29:33

  So I can use DAQmxWriteDigitalScalarU32 to write to each task independently?

  for example:

  DAQmxWriteDigitalScalarU32 (th1, 1, 10, 0 x 1, NULL)

  DAQmxWriteDigitalScalarU32 (th2, 1, 10, 0 x 2, NULL)

  DAQmxWriteDigitalScalarU32 (th3, 1, 10, 0 x 3, NULL)

  ...

  DAQmxWriteDigitalScalarU32 (th6, 1, 10, 0 x 6, NULL)

  These tasks will interfere with each other because they use the same port, but are assigned different lines?

  If this isn't the case, I bits to the data, if the task/channel does not start at the Px.0 line?

  Thank you!

  Yes, as long as you use the same line on different channels, they must not interfere with each other for this reason, you can create a channel by line if you wish

  The reference to using the DAQmxWriteDigitalScalarU32 function:
  "A sample of the integer unsigned 32-bit unique, wrote to a task that contains a single digital output channel. "Use this format for devices with up to 32 lines per port.

  http://zone.NI.com/reference/en-XX/help/370471AC-01/daqmxcfunc/daqmxwritedigitalscalaru32/

  So yes, the DAQmxWriteDigitalScalarU32 can write on each task independently

• DASYLab sends only a single string using RS232

  I can send one channel when the program began.

  After that the port is left open but Dasylab does not send the following string.

  I used a comportmonitor to see what is happening. DASYLab closes and reopens then the port for the shipment of the first string.

  The series of Dasylab output is configured as follows:

  -No entry of order

  -A single command

  -Output format: [a] \r

  What could be the reason?

• Addition of several global virtual channels

  Hello

  I had a very simple function written in CVI which adds several global virtual channel

  DAQmxErrChk (DAQmxAddGlobalChansToTask(g_TaskHandle, linesName)); //linesName consists 2 global virtual channels seperated by ",". E.g. "Power, Com" where Power = port1/line0 & Com = port1/line2
  

  There is also AddGlobalFunction in MEasurement Studio, but it allows adding of single channel only:

  Task localTask = new Task();
  localTask.AddGlobalChannel(linesName); //Get Expetion here = -200486, Specified Channel not in the task. When I give a single channel name..it works
  DigitalSingleChannelWriter doWriter = new DigitalSingleChannelWriter(localTask.Stream);
  doWriter.WriteSingleSampleMultiLine(true, states); //atates is the array of type bool which consists of value for each channel
  

  It is not possible to add multiple Global channels to a task?

  We have recently acquired license Measurement Studio and try to port/compilation/write our old libraries (written in CVI) inside.

  Is there a help line that compares the CVI C functions with the respective functions of DAQmx .NET?

  Thanks in advance!

  Ciao

  Hello

  It seems you are right. The method definition specifies that it only adds a channel:

  public NationalInstruments.DAQmx.Channel AddGlobalChannel(string channelName)
      Member of NationalInstruments.DAQmx.Task
  
  Summary:
  Adds a preconfigured, global channel to the task.
  
  Parameters:
  channelName: The name of the global channel to add to the task.
  
  Returns:
  The global Channel.
  
  Exceptions:
  NationalInstruments.DAQmx.DaqException: The NI-DAQmx driver returned an error.
  

  This could be explained by the fact that the function returnes the proper object of channel associated with the global virtual channel you created.

  I tried to check the reading code 2 Global virtual channel using the DAQ Assistant in Measurment Studio but I wasn't able to get a large part of it (the generated code creates two consecutive calls to the method "CreateVoltageChannel".

  What happens if you call AddGlobalChannel twice?

  Task localTask = new Task();
  localTask.AddGlobalChannel("Power");
  localTask.AddGlobalChannel("Com");
  

  I don't have the time to try this so far, but my understanding of the help file, I guess it could work.

  Best regards
