PWS4000 and Signal Express

Hi,
I recently get a PWS4305 power supply, I installed SignalExpress as recommended.
I just want to generate a signal and control the PWS with labview.
So I selected 'add step' ->'tektronix'->'generate a signal' -> 'tektronik power supply'.
Here, a display shows two line, one for the voltage, another one for the current.
I can find my PWS in the VISA Ressource. But how can I generate a signal ?
Thank you

egfrgr,
I believe you may need to download and install the following SignalExpress step before using your PWS4305:
LabVIEW SignalExpress Step for PWS4000 V2.0.0
Please read through the release notes for installation and usage instructions, copied here for reference.
Steps for using the Steps:
1. Run the setup.exe provided as part of Step Installer.
2. Open the LabVIEW SignalExpress Tektronix Edition software.
3. Click "Add Step" in the LabVIEW SignalExpress Tektronix Edition main menu and select Tektronix-> Generate Signals -> select your instrument series.
4. The Step appears in the Project View of Signal Express and is ready to be used.
5. Connect the instrument to your PC.
Note: You can check the connection to your Instrument using the Measurement & Automation Explorer or the TekVISA OpenChoice Instrument Manager.
6. Next, select the device in the LabVIEW SignalExpress step by selecting the "VISA Resource" tab and selecting the device in the "VISA Resource Name" drop down list. At this point, the interface is ready for use.

  • Report generation toolkit and signal express user step : problem of closing reference in "Stop" event

    Hi all,
    I'm trying to make a package of Vis to easily make Excel reports with Signal Express. I'm working on LabVIEW 8.2.1.
    I'm using the report generation toolkit, so I build a .llb from my project which contains all the hierarchy of my steps, but also the hierarchy of dynamic VIs called.
    I have made some steps, like "Open Workbook", "Write Data", etc.
    My steps run well, excepts one step : "Close Workbook".
    If my "Close Workbook" step is firing on "Run" Signal Express event, I have no error, so my reference is properly closed.
    But if my "Close Workbook" step is firing on "Stop" Signal Express event, I have an error "1", from "Generate Report Objectrepository.vi".
    I feel that I'm trying to use a reference which has been killed in the "Stop" step...
    I would like to know what exactly do Signal Express on "Stop" event and why my close function does'nt run well.
    Thanks,
    Callahan

    Hi Callahan,
    SignalExpress (SE for short) does the following on the Stop event:
    1. Takes the list of parameters that SE found on your VI's connector pane, and sets the values that the user set from the "Run LabVIEW VI" configuration page, if any.
    2. Then tells the VI that SE is running the Stop event by setting the Enum found on your VI's front panel. This in turn should produce some boolean values telling your VI to execute the Stop case.
    3. The VI is then run, with those values and states.
    4. SE checks to see if any errors where returned.
    5. Since this is the Stop event, SE releases the reference to the VI which it possesses.
    Questions for you would be, is the reference to your Workbook linked to a control on your connector pane, or held in a uninitialized Shift Register. If it's held in a Shift Register, SE would not be aware of it, and would not be able to affect that reference.
    Hope that helps. Feel free to post your LLB if it doesn't.

  • NI VISA and Signal Express - Error -1073807202

    So I did a search on this very common error that I'm also having, see error1.jpg. So one of the responses was to try and make an installer which I'm trying to do, see error2.jpg. I hope that is the right thing to check to fix the error (nobody said in the previous posts that I read). Then it asks me to find Signal Express. So I get out my DVD of Labview 8.5.0 and point it to the location (J: drive), see error3.jpg. But then Labview tells me that it is an invalid location. I mean WTF? I'm getting really annoyed by now and do another search of the forums. I find a post that says to look in MAX to see where Signal Express is located. So I do that and then put that location into the installer builder dialog box. Guess what it tells me, see error 4.jpg. So now what do I do????
    Solved!

    Are you getting error 1 when running an application on a deployment computer?
    Yes, the error happens when I install the application (using the installer I built) on both the inhouse deployment computer and the computer of a customer I sent the application to.
    I checked the deployment computer and the RunTime Engine is installed, but I see no referance to VISA. Surely you're not suggesting that I ask my customer (and any other customer who requires the application) to go to ni.com/support to download the 28.5 MB file (if my memory is correct) for the VISA drivers just to talk to a com port. So I need to fix my installer.
    So I have a couple of questions.
    Has this distribution problem been fixed in LabView 8.6.1? I have a copy just never installed it as I saw no real need to upgrade since my system so far has been working.
    Did I check the right box, NI-VISA Runtime, (for Signal Express) to get the installer to include the VISA drivers?
    I would like to get the next version right as I'm sure my customer has a reduced opinion of me for sending him a program that doesn't work.

  • Problems activating signal express 2.0 in labview

    Hello,
    I have purchased a copy of LabVIEW Base Edition 8.2.1 and Signal Express 2.0.  I receive the following error when I create a LabVIEW VI containing a Signal Express VI (in this case a Signal Express Create Signal VI):
    NI_MAPro.lvib:
    This library is invalidly licensed for this computer.  Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
    NI_Gmath.lvib:
    This library is invalidly licensed for this computer.  Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
    NI_AALPro.lvib:
    This library is invalidly licensed for this computer.  Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
    I have activated both the LabVIEW application and the Signal Express application and they both work fine indepedently.

    Some SignalExpress 2.0 Express VIs require functionality that is only available in LabVIEW Full or Pro.  Therefore, if you have LabVIEW Base and drop the Create Signal Express VI, your VI will be broken.  (If you convert the Create Signal Express VI to a subVI, you could find the VIs in question).

  • Signal Express not activated with Labview Full Development System Volume License

    I'm using a volume license manager to generate license for disconnected machines.  I just upgraded to Labview 2009.  The license files work for labview but are not working for signal express.  I have the Labview full development system which included signal express in the past.  Both labview and signal express work fine on my computer that also has the volume licensing manager software installed.   This computer is connected to the license server.  I need to get signal express activated on my disconnected machines. 

    LabVIEW Full Development licenses still include Signal Express. Are you saying that whenever you are connected to the server you can run Signal Express just fine, but whenever you create a disconnected license Signal Express is not able to launch? Can you verify that you are, in fact, checking a license out from the server whenever you are connected to the network?
    If you still have trouble I would recommend calling NI support so we could get more informatioin (such as your license file, contract ID, etc).

  • Signal Express Program Freezes After Driver Install

    Hello,
    I recently installed NI-XNET 1.4 on my machine and a few days later I went to run a signal express program that never had operational issue until after the driver install?
    What could of happened to this program to cause this failure?
    I have other SE programs that load effectively after the driver update but this particular one does not. 
    Any suggestions would be appreciated. 
    Tim

    Hi smoothdurban!  Thanks for posting!
    I'd like to get a little more information from you to see if I can get your signal express programs back up and running.  First, have you changed anything in any of those programs since you were last able to run run them?  Also, have you changed any hardware in your computer recently? XNET and Signal Express exist basically independently of one another, which leads me to believe that the installation of XNET was not the issue.  However, one step to take to verify that nothing was altered in Signal Express during the XNET install would be to repair the Signal Express installation.
    On a Windows machine, you'll want to go to your control panel under your start menu, then navigate to either "Add or Remove Programs" or "Programs and Features" depending on what version of Windows you are running.  You'll next want to navigate to National Instruments Software, then double-click.  Navigate through the list to find NI LabVIEW SignalExpress, then click the repiar icon in the window.  You will need the installation file you used previously to do this.
    If this doesn't work, please let us know!

  • Labview Signal Express and Matlab

    Hello,
    I am using Labview Signal Express to acquire and log data from an injection moulding machine (with NI USB-6218).
    The logs contain more than 65000 samples so my boss told me to treat the data with Matlab.
    Can anyone tell me how to do that? (I think that I have to export these data in a text file before but how???)
    Thank you very much for your help
    Regards.
    Helene

    Hi there, I’m currently studying mechatronics in Sligo institute of Technology in Ireland and we have to do a SCADA project using LabVIEW to control an injection moulding process. I work in the Water and waste water treatment area so I’ve no experience of Injection Moulding. I found your address on the web and was wondering would you have any screen shots of what an injection moulding SCADA interface would look like or a schematic/P&ID  of an injection moulding process. Any help would be greatly appreciated. Regards Richard Crowe

  • Zooming x and y axis in signal express Data view

    Dear All,
    How can I zoom in both and y axis in signal express data view?
    sincerely,

    You can zoom either axis by changing the min and max labels to the value you want.  Click on the label and you can edit the label.  To zoom the X Axis you can also select the zoom button next to the axis.

  • I PXI 1010 with Digital Osci, RIO cards. Any simple projects to illustrate PXI with Signal Express and/or using Digital Osc.?

    I have PXI 1010 with card for Digital Osc. Also have ELVIS. Any suggestions on oa simple project to illustrate applications of PXI - using Dig OSc and/or ELVIS. Any suggestions to illustrate PXI with Signal Express exercises. This is for undergraduates in EE Engg.

    Hi, yes, that does help, thank you for your reply.  Signal express does make it easy to work with multiple devices, as I am, though something seems to be amiss with the timing between cards.  For example, setting Signal Express to do nothing more than log data at 100 pts/sec on all channels on all three cards (PCI-6289), and using the software trigger in Signal Express to start the digitization process, and the stop button, to stop data logging, certainly seems to be a very convenient solution.  However, the longer I record (an hour seems to be enough time), the more likely that a signal recorded on all three cards, will not synch, point to point, (comparing signals recorded on channel 0 on all three cards, which I believe should be captured simultaneously through out the recording process, for example) and data recording does not stop simultaneously on all three cards.  I can handle the data logging not stopping simultaneously, but my source signal apparently not being recorded synchronously is a whole other problem, and the impetus for my question.  Thanks for the tip about NI-SCOPE, I was going to start working with that on a different project.
    I am using the most recent versions of SignalExpress, NIDAQmx drivers, etc., on a PC running 64-bit windows 7.
    regards,
    Brian

  • I have Airport Extreme as the base unit and an Express unit in a room separated by a brick wall to improve signal. Express shows a green light indicating signal but my iPad does not perform well. How can I improve other than hardwire ethernet connection?

    I have Airport Extreme as the base unit and an Express unit in a room separated by a brick wall to improve signal. Express shows a green light indicating signal but my iPad does not perform well. How can I improve other than hardwire ethernet connection?

    Other suggestions, and more info about the nature of the problem, may be in this Apple tech note.
    http://support.apple.com/kb/HT1365
    For example, you might find that the brick wall is not the only problem. There may be other devices pumping out enough wireless interference to be making things even worse.
    I agree with Bob Timmons that Ethernet is best and most reliable. And that powerline (which I use) is easier and potentially faster than wireless...but only if your power lines do not have electrical devices plugged in which produce electrical noise on the line. Powerline will be slower than Gigabit Ethernet.
    Ethernet cable is the only way to ensure that the signal goes directly there in a shielded way for a clear fast signal. Wireless and powerline are much slower because of all the other things the signal has to fight past to get to the other device.

  • What are the main differences between Signal Express and Labview?

    National Instruments provides a matrix so one can quickly compare the
    various versions of Labview but no comparison of Signal Express with
    Labview. Hence how does Signal Express compare with Labview? What
    are some of the things one can do with Labview one can't do with
    Signal Express?

    Howard,
    You clearly don't know what you are talking about. There is no "graphical version" of LabVIEW, there is just LabVIEW. Click on the article "Is LabVIEW a general purpose programming language?" written by the Jeff K. for some easy reading from a few years ago. It is all still true (except that object oriented features and recursion have been added in recent versions).
    One of the main points at this years NI-week was the discussion of how processor development is switching more and more to multicore designs  to improve performance because a simple boost in clock frequency is becoming more difficult. Linear, text based code is not well suited to take advantage of multticore design, while the dataflow based LabVIEW programming language automatically scales well to multiple processor cores, without any need to rewrite older code. I would say that only LabVIEW is futureproof in this respect. LabVIEW programmers are not wimps that are simply too stupid to write text based code. LabVIEW is not a toy language for people that don't want to learn a "real" programming language.
    LabVIEW is arguably the best programming language in terms of getting things done! I've never felt limited with LabVIEW and my programs often don't even have anything to do with data acquisition or instrument control. The difference between text based code vs. LabVIEW is like "DOS vs. Windows", "Radio vs. HD television". "Trilobyte vs. Homo sapiens" (sorry Putnam ). Text based code is monochrome, archaic and outdated and its linearity imposes unecessary constraints on the programmer that can only be (partially) overcome by wasting even more time throwing even more code at it.
    Sure, a seasoned text based programmer will initially have problems adapting to LabVIEW, just because you would need to adapt to and embrace the power of dataflow and not try to make a literal translation of the text code to LabVIEW, retaining old habits. If you get stuck, come back and ask here in the forum.
    You were looking for object oriented features and failed. All you need to do is a quick site search. All the information is out there. Just because you cannot find it in the first five sentences of the glossy brochure does not mean it does not exist. Maybe you want to read one of the application notes such as:
    LabVIEW Object-Oriented Programming: The Decisions Behind the Design
    In general, you should avoid judgement until you have all information. Your opinions seem quite biased and superficial and not really based on hard facts.
    Initially you asked about the difference between signal express and LabVIEW.

    No thanks, there has to be a better way to get an answer to my

    If you would answer the first question quoted above, we could certainly help you with the decision. Isn't that the main purpose of this thread?

  • How do I get channel names written into a logged ascii file in Signal Express

    Hi there,
    This maybe a rookie question but I am a relative rookie to this software, and I hope it has an easy fix!
    Background:
    Take a load of analogue inputs from a DAQ device into Signal Express, first thing that hits me is that unlike labVIEW you cannot right click in the channel configuration window and change the name from say... Dev2_ai0 to Air Pressure? I feel that if this was possible then I would overcome my problem? anyway I can't so onwards...
    I goto the DAQmx Acquire window on the top left and can right click and rename the channel, which is great... however this does not translate to the logged data as I get the ai0 channel names across the top of the columns and not the names that I have put in.
    Is there anyway of getting data like the attached snippet?
    Many thanks for your help in advance.

    Channel names.gif ‏4 KB

    Hi Dan,
    Thanks for the reply, that has certainly fixed my issue as I wasn't expanding the channel and selecting the channel that I had renamed.
    One last thing though:
    I now not only get the individual channel name but the prefix for the DAQmx Aquire, for instance I get the Input of Braketest and then the channels under the input data.
    It looks a bit like this....
    Braketest - Front Pres
    Braketest - Rear Pres
    Braketest - FR Temp
    Braketest - FL Temp
    etc etc...
    Now all of the channel names at the top of the columns have this long name. Can this be rectified? can I remove the "Braketest" bit?
    By the way I am saving it as an ASCII so that I can read it in excel.
    Many thanks, Neil.

  • Using Signal Express VI for DAQmx, timing & file size issues

    I am using a Signal Express VI with my DAQmx. Long story short, my DAQmx VI's don't work in LV 8.6 (possibly IT installation error). I have a few issues (I'm a beginner so be easy).
    First, I'm confused on how to get the timing correct. I am trying to read a 100 samples (2 channels) average them and repeat this at 30Hz and record this data.
    Second, everytime I open the Signal Express VI (in my block diagram) and change sampling for example, click OK, then save my VI before running my program. I noticed the file on disk increased in size by the megabytes! All I changed were the sampling settings.
    I appreciate any input, thanks in advance!

    To your first concern, it sounds like DAQmx was installed before LabVIEW.  Just reinstall DAQmx and it will work fine in LabVIEW.
    For you second concern.  To get 100 Samples at 30 Hz, you will need to change your channel setup in signal express.  You will need Continuous Aquisition, with 100 Samples to Read at 3000 Hz.  Then you code should work as expected.

    Hi Ewan,
    Uninstalling and reinstalling in the right order would ensure that everything was properly associated. However, I don't think that should be necessary yet in your situation. Please go to Control Panel > Programs and Features > National Instruments Software to see the full list of National Instruments software you have installed. From here you should be able to select any individual installation from the list and select "Repair". Instead of just seeing that something is already installed and exiting, this should go through the installation and check for corruption. As well, this should add the correct associations if they were currently missed due to the order of installation. 
    Please try running a repair of SignalExpress 2013 and restarting your computer, then check to see if the functions palette in LabVIEW is fully populated.
    Thanks!
