• my channel DAQmx property node missing RTD?

  RTD may be available in the menu shown? I do not have a RTD hung right now; could be the problem? However, I don't have a thermistor or thermocouple and these options appear. I'm putting A, B, C, and R0 by program.

  

  Hi Greg,.

  By default, DAQmx filter properties that are not supported on the devices installed. So if your device does not support the RTD channels, then this is quite normal.

  However, one of your previous discussions spoke the USB-6009 case, so I tried with it. The 6009 supports channel RTD but the property for the 6009 filtering info missing properties of RTD, which is a bug. I dropped the CAR #295521 on this subject.

  The workaround is to set the property filtering node to "Show all attributes": lack of properties in the property DAQmx nodes

• Crash of LabVIEW with nodes of Boolean property

  I work with a set of Boolean buttons and when I call a node property for the button and try to set the class for the reference entry in a script of NI845X I2C or configuring LabVIEW 8.0 give me a tile of error indicating that:

  LabVIEW .exe has incountered a problem and needs to close.  We are sorry for the inconvenience.  I joined the main array with Boolean properties that I'm changing the class on.

  The main Boolean buttons are in a cluster and loop until one of the buttons is true.  While the index rose so I can retrieve the text of the button to bring the state machine.

  Jeff,

  If you can open the VI and go to the block diagram and one property buttons and right click on it.  Go down to "select class", NI845X, and then choose between the two choices of NI845x I2C.  Then once you have selected one of the two classes down the cursor down to the property select box below the error in and out and out property and config in.  Once my LabVIEW aura error within 5 seconds and then close after I click on the 'OK' button in the slab of the error.

  Try this and see if you get the same results.

  What you do makes no sense at all!

  Why you try to change the property node of a Boolean control to a class of N845x?  We do not have this installed class, so we will not be able to reproduce your problem.

  You don't have any kind of reference wire connected in these property nodes.  If you did not have a wire of the correct class reference, then perhaps LabVIEW would know what you tried to do and would not crash on you.

  If you dropped an empty property node in the palette of control of the selected Application class, it always crashed on you?

  What happens if you have disconnected the chain wire coming out the property text node, then tried to change the class, it would break.

• What channel DAQmx property corresponds to "name" entry "DAQmx create Channel.vi?

  Hello people,

  I am changing a program, I have inherited so that it uses DAQmx virtual tasks rather than have the task and the channels created by programming of in the code.

  In the existing code, the entry 'name' on the 'DAQmx create Channel.vi' is wired with a value.  When you use a virtual task DAQmx, I do not use the 'DAQmx create Channel.vi', but I still want to set the values of the "name" in the code with the help of a property DAQmx node.  However, I can't find a property called "name".  Such a property exists with a different name?

  Best regards

• LabVIEW 2015 Init_Open_Close.vi equivalent?

  Can someone help me determine what to do to update an old program LabVIEW 15? Currently, the program uses Init_Open_Close.vi as a couple who are no longer available and must be updated. I do not know what new function to use to replace the or what other measures should be taken. I have attached some photos of my current program.

  I am also having a problem with a 32-bit 'file dialog box Wrapper.dll' and must use a 64-bit version, but do not know how to create/change that either.

  Look in the llb in the zip folder. It can work for you.

  See you soon,.

• LabVIEW 2012 Activation issue.

  Hello world

  A couple of months, I buy a DAQ which came with LabVIEW software Student 2012. A few days ago I was about to install on a PC, but I realize that the series tag was torn (perhaps as you unpack the things I buy this year there). I have not opened the package that contains the DVD (or CD) of LabVIEW, just in case where I'm not supposed to to do, because I don't know if the same serial number will be inside.

  The serial number with "S/N" feature and then I see almost 8 characters (the 8th is almost visible), but I think the series should have 9 characters.

  Can someone tell me what I need to do?

  Thanks to anyone who can give a comment about it.

  Yours faithfully,

  Diego.

  Hey there;

  No worries, most of the LabVIEW Student Edition drives have serial number printed on them

  Where can I find the serial number to activate my NI Student Edition Softare?

  Hope this helps!

  Greetings

• How to find where - activation - Set Item Property

  In the form of the
  We have four block of data.
  Leven - Traigger - once - new - form - Instance - form contains:
  
  SET_ITEM_PROPERTY ('CONTROL.update_name', ACTIVE, PROPERTY_FALSE);
  
  
  
  But to some siginals it is activating and user can update the name.
  
  Now I want to know where is the code is written on the WBF (which activates the values)
  
  
  Thank you

  Hi AppsLearner,

  Please learn how to identify your version of shapes in each post.

  1. open FMB in the form builder
  2. go in find and replace PL/SQL... Location depends on your version. Under tools or Edit

• If Google is encrypted on Firefox, what about Yahoo? And that, said the do not active channel followed just the opposite. Help, please!

  If Google is encrypted, what about Yahoo? In addition, said do not select do not follow because it activates the contrary - at least with Google - all comments?
  Thank you.

  The setting of 'Do not Track' is a feature of private life, the effectiveness of which depends on the destination site. If you choose to have Firefox send one request of 'Do not track', it is up to the site to honor this request. Some, some will not.

  I don't know what Google does in response to the TSD, but if you are connected to your Google account when searching, so of course what you do are already linked to your account...

  About Yahoo, search Yahoo via a secure connection? You might install or create a custom search plugin that uses the HTTPS protocol rather HTTP if your search bar and address bar searches are automatically encrypted. I would like to know if that's what you had in mind.

• 'Length' of reading TDMS channel property

  Hello

  I wonder if someone could point me the right direction please. I could not seem to be reading "Length" property of TDMS channels using vi «PDM get properties» I read it easily. In the worst case I might eventually write a 'Channel Length' property at the time of closing vi after dividing the total duration of sampling frequency and its reading back! I hope that there is a very good way to do this?

  It would be useful to see your code. He did to wire a digital constant to the type of input data? When left unwired it looks like a string, and since it is a numeric value it returns nothing.

  Also, make sure you have the name of appropriate property for the file EXAMPLE.tdms (example of file supplied with Diadem) in Diadem property Name length is displayed but when using TDMS get properties, you can see that the name of this property is actually NIChannelLength.

• Activating/Deactivating IEPE power switch for voltage 9234

  I use this material: NI USB9162 or cDAQ9172 with the NI 9234 module. I want to be able to select weather to use regular accelerometers or IEPE accelerometers with the 9234. I built a LabVIEW Vi where I want to be able to configure the channel of the accelerometer as a voltage channel and input sensitivity data later. Here are my experiences:

  1. If I use "Voltage Custom with excitation" I get the message "no device supported found. What happens in MAX 'task to create', labview DAQassistant or 'DAQmx create a channel' + 'personalized with excitation voltage.
  2. If I use 'DAQmx create channel' (with or without excitation) and define the source of excitation and value as a property I still have the same problem
  3. If I do as well as in 1, but with the acceleration I don't have no problem Iex source parameter and value. But this isn't what I want.
  4. If I use "IEPE the enable" inside the MAX test panels I have no problem using the IEPE accelerometer and get the tension
  Can someone help me understand how I could activate an IEPE accelerometer as a voltage source?

  The problem is that you are using HAVE. Excit.DCorAC. This isn't the right to property.  AI. Excit.DCorAC must be set to DC for the 9234, by default.

  If you want to configure channel matching, you must use I. Mating.  You can get this in analog input-> General Properties-> entry Setup-> coupling

  If you want to configure each channel separately, use Active Channel in the node of your property to select a channel.  All the properties that you configure in this node is not available for the specified channel.

• Adding channel CJCS virtual/physical to existing task

  Hello

  I have a NI 9211 TC modules that I use to acquire temperatures through LabVIEW 2013 SP1, I have an existing task created in MAX.  I want to follow the CJC temperature sensor as well.  After looking at several positions, I discovered how to assign the physical channel hidden in a virtual channel in LabVIEW and then view the CJC value.  BTW...  Where there is under good which shows how to do this for the cDAQ series... find the 'AI Temp sensor built' is not clear (look under "analog EntrΘe, more").  But that part works now.

  -->, I want to add this channel CJC to my existing job, but I get an error.  See CJC1.vi

  Or, as an alternative, I would like to acquire the CJC temperature and acquire temperatures 8 other channels and then combine them somehow for display, recording, etc.

  Note: I want to keep the data in the format of the waveform, so they work as part of a broad data acquisition program that I have.  And I want to continue to use the existing task as it contains the calibrations (via the wizard of Calibration MAX).

  Here is the error that occurs when I run CJC2.vi with the active disabled code block.  (sometimes not is displayed after you press the Stop button)

  Error-200072 occurred at .vi:7050002 DAQmx Create Channel (I-temperature-built-in sensor)

  Possible reasons:

  Duplicate the layers in the list of physical channels are not supported by this unit.

  Channel name: _cDAQ3Mod1/_cjtemp
  Dual channel: cDAQ3Mod1/_cjtemp
  Physical channel: _cjtemp
  Feature: cDAQ3Mod1

  Name of the task: task of DAQ3

  Now, how to combine the two?

  Thanks for the help,

  Knowledge base seems to be a little confused right now because it only shows the node property for channel playback of strength. It's the correct property to read from a channel of CYC while you use it, but we must also set the CJC channel as an active channel first. The following snippet is the right way to do this in the context of this thread.

  Please note that you must use the built-in CJC source for that to be applicable.

  

• 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.

  

• Time real ADC/DAC for SMPS by using Labview and USB

  Hi all

  I asked the Sales Department of this same question, so here's a two-pronged approach:

  I am reserching a control algorithm for power switching, and so far, its performance simulations seem to be good.  Now, the goal is to implement the circuit from the experimental data.

  I've seen several NI USB DAQ boxes that seem to have the performance, I'm looking for (for example, the box USB-6211 a sampling rate and resolution I need).

  The control algorithm uses the following mathematical functions: add/sub/mult/div/exhibitor and derivative/integral.

  My question is this: is "strong enough" Labview take four-channel data 250Ksps, crunches the numbers in an equation and spits out the answer to an analogue on the channel, while time REAL?  I'm looking for a rate of analog output of ~ 100 kHz.

  Thank you for any suggestions you have!

  -Rick

  Hey,.

  So if you were trying just to perform an input or output, then the box USB-6211 would certainly be able to treat it as the machine clock could manage the inputs/outputs, no software. However, what you are wanting to do, basically a feedback system, he will have to avoid (at least to a USB device) because you need to be able to specify Active which is the output. So, for this reason alone and the fact that you want out of 100 kHz, this device and the USB devices in general will be not an option any what software you use, LabVIEW or otherwise. On another note, you want to make sounds more like live update, not in real time, which is more on the jitter. Bottom line, for these kinds of requirements, you might need to move to an FPGA card, something like the NI PCIe-7841R would work. It's more expensive, but for your needs, FPGA will be the only option and it comes down to the latency of the bus, but also the response time of software. With FPGA, as shown in the first scheme of the following document, you basically close your software through hardware loop.

• Unknown channel or feature name repeated

  Hello

  I want to connect NI SMU-5451(waveform generator) and NI-SMU-7966R(Flex RIO) with peer-to-peer technology. I took an example of NOR-FGEN, which works perfectly, but when I use it in my project there is a mistake takes place - the "unknown channel or feature name repeated" What should I do to fix this?

  Hello

  I saw this post in another place, and there was a proposal to reorganize the properties in your node as well as "Active Channel" is the first.  As mentioned on this post, property nodes run top down and you may need to specify the channel before enabling the peer to peer.  Did you get a chance to try this yet?  You still see the same error?
