Script to output channel status

• Call to a single value to an output channel for A Table need help

  I filled an array that contains all the values in all the channels of my series of data. I am now looking to channel calculations to provide weighted averages and an overall average for the value of the trial. These data will be produced in a new table called 'total table. " This Total table should only have one value per channel.

  The question that I am running is 2 times. When you do the arithmetic channel, mainly channel using "ChnSum" DIAdem amounts does not truncate all data in a new set of data. It retains all values and adds the last block with the sum of all of the channel as a whole. I need or be able to get this last value dynamically (because not all my datasets are the same length) or I need to generate a new string that has only the value of the sum. Is there a way to do this?

  Here is what I try to do but kind of pointless. A screenshot of what looks like the output of the table after treatment of this code is attached.

  "Complete total table with values from calculations above.

  For j = 1 to selectData.MultiSelection.Count

  Counter = counter + 1

  length = ChnPropValGet ("[" & selectData.MultiSelection (j).] ") Index & "] / Cumulative fuel ', 'Length')

  If counter = 2 Then

  [A bunch of calculations of the new output channels channel]

  Call View.Sheets ("total table"). Areas ("field:" & Counter). DisplayObj.Columns.Add (ChnFind ("(" & selectData.MultiSelection (j). ("The index &") > 0 "(, longueur-1))"

  End If

  Any help would be appreciated.

• Peripheral output channels Custom not updated

  Hello

  I'm having a problem where my Custom peripheral output channels is not up-to-date in Veristand.  At first, I thought that perhaps I was not passing simply return all of the channels that I read but I got the Panel of peripheral pront open when it runs so I could see directly the data being transmitted and is all there (see attachments), but once it is written in the FIFO output is not are they displayed in Veristand on indicators of the workspace.

  The only thing I thought is maybe that VeriStand is reading the FIFO faster unit is written result in default values being read.  Ideally Veristand would maintain that the last value read if she meets and empty the FIFO, but since this part of veristand is not available to my knowledge, I have no way to confirm or modify this behavior.

  Anyone who has ever met this problem?  Thank you.

  The problem has been less channels than veristand supposed to write the FIFO output.

  Device to start the custom first for a fraction of a second he wrote number of channels or perhaps even no channels in the FIFO output coming much too fast to notice at the time wherever the front opens upwards so it appeared as if all the right lanes were sent.  Apparently if less than channels are added to the FIFO Veristand is pregnant, she's one of the remaining channels updated.

  Therefore if VS waits 20 channels and on the first round only 10 are written then from there he will send only 10 channels even if I may continue the planned 20.  This could also be the result of the mechanism by which work RT FIFOs.

• Definition by digital input or output channels program

  Which classes/methods in Measurement Studio NIDAQ-mx support let me set programmatically a digital channel for entry or exit? The only methods I met provide lists of channels of i/o configured previously.

  Thank you

  If you are using a device with digital two-way lines, then you have not specifically set a channel as ot of input-output. Use string functions DAQmxCreateDIChan or DAQmxCreateDOChan with the lines that you want to use. The line will be automatically configured as input or output.

  If the device supports the digital two-way, you cannot define an input as string vice versa and the output channel.

• Read analog output channel value internally

  According to this you can read the values of analog output of return without having to physically connect the wires.

  By using the technique described in the example given (DAQmx_Read_Output_Internal_Channels.vi) I'm reading a current area of OCCUPANCY on my compactDAQ cDAQ-9174 with a module of analog output current OR-9265.

  The output channel is created in MAX and my vi can write values to him without problems

  But when I try to create an analog input channel to read the output, an error occurs.

  What I am doing wrong?

  This is not supported by my hardware?

  Or is the example given in the above incorrect link?

  The example is 10 years old. Maybe, it does not work in LV2013.

  

  

  Hi Jocker,

  The link was not attached to your message, but I guess that's it: http://digital.ni.com/public.nsf/allkb/CB86B3B174763C3E86256FFD007A2511 as there the example of vi you mention.

  The error you are getting is due to the use of the channel for analog output and trying to configure the task as a task of entry. You must use _aoX_vs_aognd as the channel of the task rather than on the output channel. This compares to the ground for the analog output values.

  The NI 9265 is not on the list of the C Series modules that have internal channels:

  http://zone.NI.com/reference/en-XX/help/370466W-01/mxdevconsid/9211interchan/#GUID-E13ADE46-5CB8-491...

  So I guess that the module is not able to compare its output to ground. He would appear in the dropdown of the channel names if available.

• How to synchronize 2 digital output channels that have been created with DAQmxCreateCOPulseChanFreq

  Hello

  I use peripheral USB6221.

  I created two digital output, operating on a frequency of 75KHz and duty cycle of 50%. But I need a period of 1 microsecond between the two channels.

  I have craeted the two channel on the same task and guess if I use a delay of 0, the channels will be synchronized, but looking at the scope, the channels are not synchronized. Here's the code I used (I checked also all return codes of coarse and fine).

  Thank you

  Hello Danny,

  If you are looking for more output channels of the Digital pulse trains, you can create 1 task of counter that is used as the clock for digital multi-line data output. For this digital task, you will need to make the clock source line PFI for the output of your task of counter. Once this has been done, you will need to create the digital signal for each line of output and write to the card. The example called write dig Chan - Ext Clk will explain how to set up the digital task so that the task has an external clock (the counter). I hope this information helps you and if you have any other questions, feel free to post.

• What does "Channel status is not valid" message mean and how it can be solved.

  Whenever I have upload documents, "ms security essentials" using any Explorer of the material are downloaded. But when I try to install it, its was not and I get a message "channel status is not valid". What this means and how it might be solved.

  Dear Sandeep, thanks for taking the trouble. However, it was too complicated for me. I chose an easy option. I went and restored the system to a much older date. That solved my problem.

• First CC 2015 - 'no audio output channel valid for found a reading. Please check audio hardware preferences. »

  I just updated from CC 2014v2 until 2015.

  When I open any project or create a new and import any media type - I get a yellow warning at the bottom of the display window showing 'no audio output channel valid for found a reading. Please check audio hardware preferences. "When you press Play, no sound plays and the read head does not move.

  Here is my audio hardware preferences - Realtek is my only option. Everything was going well in 2014 CC this afternoon and I have CS6 installed, which opens and reads the clips and audio without problems while listing the Realtek as the output device.

  

  HP Z820 - Windows 7 64 bit - 128 GB of ram. Adobe apps and system to this day.

  I could solve this problem by removing all plug-in in the directory "C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore", which fixed the problem, then replacing them in batches until the returned error.  In this case, it was an outdated version of an addon Bluefish444.

• "The device has changed and no output channel is present. Open Audio hardware preferences? »

  Hello

  I installed an infusion of SSD and fresh install of Windows 7 64-bit, including the installation of Adobe CC with premiere pro and other related applications. My audio works fine, I have a portable speaker connected to the back of the audio 'line in the green plug' at the back of my office, have not had any problems with her.

  However when opening Adobe PP for the first time I get the message "the device has changed and no output channel is present. You want to open the Audio hardware preferences. At the opening of the entry default preference reads "no devices available (does not). I was unable to change the value by default using the box entrance, but was able to change the default output. I changed the default output to ' speakers (device 2-high definition audio) and after that I got an error that read "sorry a serious error has occurred which caused Adobe PP stopped." We will try to save your work)".

  Is anyone able to help with this, I don't know how to set up the audio setting is all new to me. Also do not know why this has happened given my audio works fine in any other program that I use on my pc. Any help from an expert on this forum would be greatly appreciated. Cheers, Joel.

  

  My first guess is to check and possibly update the audio driver.

• Several simultaneous analog output channels

  I use DAQmx-NOR-USB.

  I want to simultaneously generate two analog output signals, i.e. change the two outputs at the same time.

  Simple example:

  

  

  What is happening is that instead of two outputs simultaneous modification, there is 1mS delay:

  

  I want to generate premium output, using two channels, but the delayed response is not acceptable.

  Any suggestions?

  Hi Seth B,.

  Yes, it works!

  A note: to make visible this property, I had to turn on "display all the attributes" in the menu "Select filter" (right click on the node property).

  Thank you.

• How can I change the configuration for the output channels analog on a PXI-6704?

  I can't seem to understand how to access the configuration of the channels to the outputs analog (channel 33 and 35) for PXI-6704.

  This piece of test equipment is out of tolerance and must be calibrated.

  I have followed the procedure of calibration http://www.ni.com/pdf/manuals/374081b.pdf, but am getting hung up on step 8, where it is said to repeat steps 4-7 when changing the _cal_ao_current_offset. I can't figure out how to open this channel because it is not listed as a physical channel for step 5.

  I'm using Labview 7.1

  Thank you

  Hello! What you need to do is to add 'Internal channels' to your list of channels, so you can choose the _cal_ao_current_offset or _cal_ao_voltage_offset.  This is done through the drop-down list channel right click and select "I/o name of screening...". ».  There will be a check box that says 'Internal channels' and will provide you with all available internal channels to enter your vi Create Channel.  I have attached some photos illustrating how to do. See you soon!

• Bit 4 scripts to get the status of Power Supply

  Hi all

  Uses script xml ILO via cpqlocfg.exe and hponcfg.exe tools to retrieve state information to a server running the ILO 4.

  If I use the web interface, I can get information on the blocks of power and their status of redundancy as shown below - but I can't seem to get this information by using the scripting system. No one knows how to do?

  Thank you

  DAZ

  

  I found it!  In case anyone is wondering, a lot of information on the server is available by querying with the ILO "GET_EMBEDDED_HEALTH" xml tag

  This refers, buried way down in the results, information on power supply (section POWER_SUPPLIES).

  Although he does not seem to ask some information about power supplies, it works!

• Script to output data storages VMs

  Hi all

  I'm new to these forums and PowerCLI.  I'm doing something that I thought would be simple, but I failed miserably.

  I want to create a script that will take a specified list of specific and output of each data store data stores and the virtual machines that are on it.

  The output from the example:

  VM data store

  --------------         ----------------

  Datastore1 VM1

  Datastore1 VM2

  VM3 Datastore2

  Datastore2 VM4

  Example of script I've tried to create:

  $Result = @)

  $Datastores = get-Datastore < Datastore1 >, < Datastore2 >

  foreach ($Datastore to $Datastores)

  {
  $Result += get-datastore $Datastore | Get - VM | Select @{N = "Datastore"; E = {$datastore. Name}},@{N="VM '; E = {$VM. Name}}
  }

  $Result

  It's just one of the many examples of scripts that I've tried and failed with.  Any help is VERY appreciated.  Thanks in advance!

  One way to do that is like that

  foreach($ds in Get-Datastore -Name datastore1,datastore2){  Get-VM -Datastore $ds |  Select Name,@{N="Datastore";E={$ds.Name}}}
