• LV-functions modeling restrictions?

  Hello

  I use LabVIEW 2011 to create a model (.lvmodel) for Veristand 2011.

  It works if I import a VI with only simple digital functions.

  When I try to import a complex more a compilation process is abandoned.

  Can what LV-functions I use in a model?

  I am trying currently to use (with shift registers) while loops, queues, events, cases-structures, sequences, - number of cycles, numeric, Boolean and comparison of functions.

  There are some variable clusters, DBL, I64 and U8.

  I will study the possibility of using the Control Design and Simulation Module for a new design, but it would be very useful to know what went wrong.

  Greetings

  Frank

  Thanks for the clarification. I think I see what's happening.

  Models should be designed to run and end immediately. It should not be a loop in the VI which is repeated over time. VeriStand itself is responsibel for the planning of the model by which invokes several times every moment of the control loop (or some decimation of it). The general idea is that models will be simply a calculation based on the inputs and parameters and then publish the output data.

  So, it seems that your model would simply be code background loop that does the calculations, but without the loop itself, since VeriStand serves as a loop. You can still have a loop in your model to take advantage of shift uninitialized registers to save state data between runs, but the loop must always have a real connected to a Terminal to stop.

• Digital validation

  I'm trying to make sure that the value of a text field is numeric when the page is sent. Apex does not seem to have a digital validation. And oracle does not appear to be an ISNUMERIC function or similar.
  
  What is the best way to create a validation to verify that something is digital? Should I use the Regex or create a custom function?

  Hello

  Create a validation of levels item, select 'String comparison' and you will find this Summit has a digital function.

  Hope this helps

  See you soon

• Extended keyboard US

  Hello

  I have reformat my iMac 27 "and re - install EL captain from scratch.

  I use a USB keyboard expand.

  Because I re - install the El Captain keys from 0 to 9 on the numeric keypad does not work anymore.

  I have try the keyboard on another Mac and they work.

  I think that there is a 'feature' somewhere to turn off these 10 keys, or to replace their digital function to navigate functions or something like that.

  But I do not know how to disable them.

  The checkbox "preferences/keyboard/keypad of the system" use all F1, F2, etc. keys as standard function keys... is not checked.

  The other keys in keypad work.

  I would appreciate your help

  Concerning

  Ben

  Ooooops,

  I forgot to tell you that the extended US keyboard is not available more-> select extended ABC.

  I try with the digital French and it does not work as well.

• premium variable length emulator

  Using the first emulator "solve the digital function", I noticed that my veriable names were being cut after 4 characters. Is it possible to see all the name of the variable? Or am I limited to only 4 characters?

  Thank you

  

  The size of the return of the name is limited at present. The variable works very well, cut it to 4.

• "Remove and rewire" feature/bug?

  I'm a little surprised by the result next to "Remove & Rewire" shortcut (Ctrl-R Ctrl-space).

  Start with this:

  

  Now select one of the ' I32' features and try the trick ' Ctrl-R Ctrl-space '. Here's what I get for the top:

  

  and for the bottom:

  

  Interestingly, if I use a "DBL", or an "increase" or virtually any monofilaire digital function, things work as expected...

  The behavior with constants is expected... If Ctrl-R is used, it will remove constants wired to the deleted object, if they are not wired to anything else. I have not yet received any complaints about this feature... people seem to want constant go away as well as the selected object when you use the shortcut Ctrl-R.

  The removal of the ball does not pass through the barbed wire because, as the code is written currently, inputs and outputs must be * exactly * characters in order for the passage must be connected.  Y ' All I want to make an exception for a digital unary and transmitting of described video wire service even if the types are not exactly?  I can see this being useful... If you use Ctrl-R in this case, it's because you expect the direct wire to preserve, right?

• multiplication of matrices

  HI, I would ask how to perform muptiplication matrix 10 x 10 with table (do not use linear algebra)...
  AxB = C (A, B, C all 10 x 10). How can I do this?  Many thanks for any help

  If you remember your secondary algebra, then it should be a very easy process to treat two 2D arrays of (I was going to say 'floats', but they could be integers) numbers as if they were a matrix and simply to perform the operation.  Have loops to auto-index through the two tables and relevant table of the functions (big hint - such that transpose) make it easy to do this in a very compact way.  Of course, if you've ever learned about matrices and how to manipulate them, it will be more complicated...

  Just thinking, you should be able to do it with two nested for loops, a matrix function and two digital functions.  For extra credit, you can add a Boolean test (followed by a Case statement that gives an Error Message If the test fails) to ensure that the two tables have a compatible size.

• Synthetesis of frequencies with filtered signals (Convolution)

  Hello

  I am a new user of DIAdem and I analysis of the signal.

  To deal with my purchases, I use several tools alreaydy implement in DIAdem. But I want to do a convolution of the signal number to make a spectrum of synthesis.

  In fact, I want to filter several frequencies on a signal and put them in a same spectrum, think a convolution of each of the signals.

  How can I do that with DIAdem?

  Best regards

  Pascal GRAIGNIC

  Hi Pascal,.

  I'm no expert in acoustic analysis, but it seems to me that you could simply add together the resulting chains of each single frequency filter digital function of the results of the ANALYSES.  The result of the calculation of digital filter in tiara is a curve of time series that contains only the frequency components with a size proportional to the contribution of the relative amplitude of frequency of such component (s) to the curve of time series (complete) original.  There is a function of multichannel totaling in the palette of the ANALYSIS of "basic mathematics".

• How to record entries and exits in file

  Salvation or

  I have the program with comments and a few outputs

  I try to record the entry and exit to the Office of the word or excel as this files

  Read and write file spreadsheet screw should do what you want.

  I have not taken the time to try to decipher what your program does, but I think you could replace all those knots of feedback and build tables by an integer data type and the rotation of the digital function > pallet of data manipulation.  You still have a node of or rfeedback to UPDATE for each of the four signals.

  You duplicated code: divided by 65535, multiply by 2, and minus 1 followed by a > comparison.  That make a Subvi and place 4 instances on your drawing.

  These simple changes will make understandable schema, reduce its size to the size of a postcard, and facilitate subsequent changes.

• The PCI-6052e does support I2C or SPI communication?

  Currently, I am trying to build a data acquisition system to test, among other things, SPI and I2C devices verification of characteristics and surveys of behaviour without advertisement above the different temperatures.  The DAQ card that I use is the PCI-6052e as well as the SCB-68.  It has 8 ports DIO, but can someone tell me if it will support SPI or I2C?  Another post in the forum indicated that it will not support 16-bit SPI, but for my application only 8 bit is necessary.  I am not opposed to research in other materials DAQ, such as the USB-8451, but would like to see if the 6052e can do the job first.  If she can't, then my next question would be; Can the 6052e and USB-8451 operate in parallel which allows me to use both analog and digital functionality?  Thank you

• Channels by 9174 and 9178 chassis

  I'm trying to figure out the most cost-effective means for the conduct of the digital output channels as much as possible by using one of the cDAQ chassis.

  The former chassis cDAQ (NOR cDAQ-9172) contained a specification of 64 digital i/o channels per chassis.  I can't find a similar specification to the cDAQ NI 9174 and cDAQ-9178 OR.  Are limited to 64 outputs both digital as well, or is limited to half 9174?  I can drive 64 lines of digital output with two modules (NI 9476), so the numberslots in the chassis is nowhere nearly as important to me as the number of channels.

  Thank you

  Matt

  Hi Matt,

  I think I found the source that lists DIO 64 as a max on the cDAQ-9172: the technical details related to off the Web page.  This is incorrect.  All the CompactDAQ chassis can support the maximum number of possible digital channels based on their number of slots; 32 channel modules is 256 channels for the 9172 and 9178 and 128 channels for the 9174.  You can use 2 modules NI 9476 to control 64 lines to any CompactDAQ chassis.

  Please keep in mind that you cannot use timed by the hardware or the characteristics of counter/timer thanks to a module NI 9476.  For more information about support for the digital functions on each frame, please consult the document "User Guide and specifications" for each frame, which is larger than the data sheet.

  I apologize for the mistake of documentation that you have found, and I spent this long to fix.

  Kind regards

• LabVIEW classification number

  Hi I'm looking for a quick way to labview order the numbers by class according to specified intervals. The comparison of the number of tools using just take me to a huge vi, which is difficult to manage.

  In the range & Coerce, as digital functions more is polymorphic, which means that its inpus will accept arrays and scalars.  When entries are output arrays are arrays.  If the arrays are of different lengths, the shorter table determines the length of the tables out.

  Then browse the table of Boolean (drug?) to find the class.

• How to extract data from waveform

  I have prepared a VI for acquisition and analysis. I have data from NI 9203 manuplate (power source). I have to use a lot of channels and more than 1 sample of a channel so Daqmx read vi out of waveform module and it is not a choice for table 1 d. How can I this form to scale data and display 2 diffferent scale given in a graphic waveform?

  The DAQmx Read returns an array of waveforms.  Each waveform is t0, dt, Y components and optional attributes.  See the palette of waveform for tools to extract the components and build waveforms.

  To make your scaling that you do these things:

  1. Select the waveform you want to scale by using the Index table or index of waveform Array.vi.

  2. download the component Y of the selected waveform.

  3. resize it if Y' = m * Y = b, where is the original painting and the Y' is the matrix to scale.  You can use the standard digital functions for * and + because they work for arrays and scalars.

  4 build a new waveform using Y'.
