• Complete equipment of simulation using LabView, Multisim, and MAX (easy answer accepted!)

  Hello, all!

  Sorry, I'm new, but I checked around for a definitive answer on this, but I'm not 100% sure.  I learn LabView for a physics of upper-division course.  We use hardware (DAQ - MX) and a mixture of laboratory equipment - mainly stuff such as voltmeters, oscilloscopes and test setup with simple components.  I also work with NIM instrumentation, but that's secondary to my needs here.  So, when I'm away from the school, is it possible to make a complete simulation of my classroom work using LabView, Multisim (for my model) and the measurement and Automation Explorer (for the acquisition of data-MX)?  I know I can create a circuit and drop it in Labview, but I'm not sure on the acquisition of data.  I hope for what is a "seamless" reconstruction of what I do in class.  I can't take a simple 'yes' or ""; as long as I know it's possible, I can find the solution.

  Thanks for the help!

  I wrote 'sim' screws in many situations where I need to work away from the hardware store.  I think that MAX has a few features, but you may be limited in the types of signals, you can simulate.

  For my sim screw, I make a copy of the original VI with ".sim" added file name.  I also change the icon in a characteristic way to identify the version of the sim card on the BD. In this way the two VI have the same connector pane and are interchangeable on the BD structure. disable the diagram can be your friend here. Inside of the VI of sim, I generate the signal in any form I want.  You can also add additional if necessary controls.

• by using labview co-simulation, how to control the PWM market factor in multisim

  I am new to the use of Multisim with LabVIEW using co-simulation. I would like to ask if there is a PWM component in Multisim, which can have its cycle have to be controlled using LabVIEW? I have an algorithm in LabVIEW that returns the duty cycle values between 0 and 1, representing the percentage of duty cycle.

  How can I control the PWM market factor in Multisim using LabVIEW co-simulation?

  Thank you very much

  Hi spectrum,

  In Multisim, find items based on functionality, there are some PWM models in the database.  Take a look at this knowledge base if you don't know how to search for parts:

• 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.

• How to view mdsplus data using labview

  I posted this question in the Council of Labview, but seems that nobody does it so far. I don't know what is the best place to ask this question. So I reposted here.  Thank you very much.

  I am a newbie to Labview. I'm writing a few vi to display and write data to Mdsplus.  I downloaded Mdsplus(labview) can discover Mdsplus functions, like mdsconnect, mdsput, ect, in vi to call a library function. But I have no ideal how to use it. I tried to use the Mdsconnect function to connect to a machine, but it still gives me an error like: Labview: an exception occurred in the external code that is called by a call library function node...  I was looking for help on the internet documents, but could not find anything useful. Could you please help me with this problem?  If you have examples of these vi, or teach me how it, it would be very useful. I'm using Labview 8 (windows). I would appreciate your help!  Looking forward for your reply.

  Oops,

  I attached properly in the previous post.

• This module requires a Lynxmotion AL5A robotic using LabVIEW arm control

  Hello world

  I'm a little confused about what NI LabVIEW toolkits to be used in order for me to program the arm Lynxmotion robotic. Somebody has arms lynxmotion robot programming experience using labview? What should be awared by selecting the correct tool boxes. Do I need to have the tools of design and simulation of control? What about embedded design modules? Please help me.

  Thank you

  Hi DK,.

  The Module digital output NI9474 high-speed Sourcing should be more than enough.

  In fact, we have a demo of work available by using the AL5D and NI CompactRIO. The concept should always be the same property.

• find idle computer time using labview

  Hello...

  My process is based on Labview. It tests the process based on the vision. I don't want ON the continouesly of the machine, I planned to stop the machine when my PC is idle. To do this, I want to know how to identify the time of inactivity system using labview. So that I can stop the machine when the process does not work.

  Thank you.

  Assuming you are using Windows, you must use the Windows GetLastInputInfo API function that will give you the time.

• NEITHER CVS using Labview Linux?

  Hi, I have a CVS here, as well as 1455 development under labview linux machine. I've used MAX to set up this CVS, but it seems that my labview is not MAX, and I can see on the site it seems to be available for Linux. Could someone point me in the right direction to set up/use my CVS using labview linux (I've got installed 8.5).

  You need to write code CVS to turn an image into a table of number using IMAQ ImageToArray.

  Then, use the shared variable or TCP/IP to return data to the host VI.

  However, there are two things to remember:

  1. an image won't be like in real-time, as show on VI target itself.

  2. because the Vision Development Module does not support on Linux, all the processing of the image on Linux must develop in yourself.

• My Clickfree automatic backup drive has stopped working, with my iMac, what is the best replacement to use with Time machine

  My Clickfree automatic backup drive I had for many years stopped working with my iMac, what is the best replacement to use with Time Machine.

  I can't even reformat the drive to try to start over, then think its time I invested in a high today but don't know where start looking so any advise would be a great help.

  Thank you guys

  A lot of users on these forums recommend OWC (www.macsales.com) Mercury Elite Pro series JEP due to their durability, affordability and quality of construction. I have about 6 of them connected to my iMac and have never had a speaker to fail. When a hard drive fails, substitute is a 5-minute process to re - use the box. To help you get started, you can find the line to: https://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB

  You can find them in various ways and with a variety of configurations of connection so you can find the one that best fits your needs.

  Good luck!

• How can I know if an external drive has been used for Time Machine and what computer it came with too?

  How can I know if an external drive has been used for Time Machine and what computer it came with too?

  I have several laptops and iMacs. I spent the relocation of the year and only used the MacBook Pro.

  Now I'm trying to figure out which drive goes with which computer

  I connected just a disk seagate 1.5 t and the first thing he did was to ask if I wanted to use it as a Time Machine drive.

  (1) if it is the TM disk accompanying this computer don't would not it have just started upward automatically?

  (2) what happens if I would have said yes?

  (3) I don't even know if it's been activated for TM. Is there a way to tell? It may hold just for iMovie files and other programs associated with a computer from my past.

  All readers of backup Time Machine contains a folder named: Backups.backupdb. If you open this folder, you'll find another folder with the name of the computer that has been saved. If several computers have been saved on the same disk, you will have several folders.

• GUID or not for use with time machine

  I am about to format a new external hard drive to save the backups and other things. On the road I can use for Time Machine, but not now. I wonder whether or not to use setting GUID in the form for the reader, because it will allow me to make a disc bootable option. Is there a reason NOT to use the GUID + OS X extended journaled on any drive that you reformat? (I ask because it is an option. A few posts on this site I get the idea that unless I want a windows or linux on readable disk, which I did not, GUID is the way to go. I don't know if I chose actually on another X - HD I got recently and am using for backups TM. I don't know, because I tried to make a bootable partition / clone and was not able to boot from this partition.)

  Secondly, I think to partition the hard drive into two GB 1 pieces in case I want to use 1 semester for backups online TM subsequently and so keep those separated from other files. Is it advisable or not? (One of the advantages are the possibility to delete backups TM: you just reformat the partition where they live.)

  I could use the GUID for a partition and not on the other or just for the two (it seems that the GUID is the recommended way to get Mac products). *

  Thanks in advance.

  * Assume that you use a GUID. Is there a problem with the help of a hard drive without formatting?

  Since you're using ONLY this disc with your Mac, then GUID partition map and HFS + filesystem (OS X Extended (journaled)) to a volume of Time Machine

  * Assume that you use a GUID. Is there a problem with the help of a hard drive without formatting?

  Why do bad for yourself.

  It is very good.  In addition to El Capitan OS X will be ONE partition a disk GUID, it's another reason for the use of the GUID.

  NOTE: If you want to put other files on this disk, will you of have saved them in another location.  And all THE data that you care, or would have cost a lot of time to recreate should be use 3-2-1. backup policy.

  3 copies (the original is the 1st copy)

  utility for 2 different devices to backup with 2 different so that a bug in one does not affect the other, and a faulty device does not affect the other.

  1 copy off site, so that you always have your data even after a natural disaster or theft

  And put the data and backup on the same disk is a "No No", as the loss of the aircraft loses the original and the backup at the same time.

• Screenshot of Tektronix MSO4104B using LabVIEW

  I am trying to acquire a screenshot of an oscilloscope Tektronix MSO4104B using LabVIEW. I am currently able to collect data from the device and have a waveform displayed on my front of VI. However, for various reasons, our preference is to capture the actual screen shot of the scope.

  I have reviewed the reference for programmers for this camera and have done countless searches on Google for an answer, but have not been able to find a solution. It seems that a few people were able to reach on OTHER Tek scopes by sending a hard copy through the port of communication (GPIB, USB, Ethernet, etc.), but according to the reference of programmers for this particular device, it seems that he will send a paper copy of an installed printer, rather than simply as a stream of data to the port which can be read using VISA controls.

  The other solution I've seen is to record the screen turned to a flash drive, and then copy the file via the port to the PC. However, none of these solutions seems to be available on this device... it's one of the more advanced scopes makes Tek... I can't believe it's so hard! Help, please!

  
  

• waveform, with an average of results using labview to O-scope

  Hello fellow engineers! I'm a first-yeargraduatestudent in CHEE at the University of Houston. Basically, I know nothing about labview. I am trying to program an application that looks like this - I collect a waveform of the signal of O-scope. This waveform does not change its characteristic shape. I need to find the wave form average of waveforms of N (100 for example). Thus, the slight changes (or noise) in the feature of form during the period mustbeaveraged out and I need to have a resultant waveform that represents the average waveform over a period. So, basically, I'm collecting the wave several times (for example 100) on a single period. The O-scope that I use now is Tektronix TDS 2024 B. It communicates with the computer via USB. The version of labview is 8.5. For now, I am able to communicate with the computer using our o-scope through labview. I already downloaded the driver of instruments of your Web site. It turns out that the program can give me only the average result I can get directly from o-scope manually. I need to have more say on average (100) using labview. I wrote a program that relies on the instrument driver that is downloaded on your website (for loop part is average, the waveform). The program that I modified and an instrument driver are attached. The program cannot be fully open, if the driver is not put in the right place in the labview (under lib inst.) When I run the program, the average waveform does not appear on the front panal and signal waveform file is not saved correctly. Is there someone can find where I did wrong and it develop for me? Because I barely know Labview, it will be even better if you can add an image or program that you have changed. I'm waiting for your creative ideas.
   
  With the best regards,.
