• How to add a record button on the front panel to save waveform data

  Hi, I'm new kind of LabVIEW and I worked on a code for an agilent oscilloscope communicate via GPIB and so far it works well on the collection of these two analog channels one by one, "Not UNLIMITED" but it does the trick (vpp, Vrms, frequency, etc.).  I've added the feature to add data to a .csv file waveform (problem: opens a dialog box until the user gathers all the data.) Solution: I want the user to save the. File CSV whenever he wants to use later on the front panel). I've added another feature to get a snapshot of the curve waveform (problem: opens a dialog box.) Solution: I want the user to save the JPEG file, whenever he wants to take a snapshot ("take snapshot" button on the front panel)).  I work with the agilent hp54645d driver. I have attached my code, if someone can tell me please how do I do this (maybe cabling and structures are solutions do not know). Thank you in advance.

  I would recommend adding a case structure just around the two record VI and a button to check the condition of the structure of each case. If you want a button to control both save functions you can put the two record functions in the same structure of business controlled by a single button. You are right in saying that the loop will cause your code runs until the stop button is pressed or until the stop condition is met. If you are wanting the while loop to stop once the recorded information you can use the button that you use to control structures case to also stop the while loop. I hope this information helps.

• A button on the front panel reset

  I use a record button on the front panel, in the mode "change when you press on. I have run the VI, then press the record button. After having intercepted the VI, the button lights. How do the button return automatically to the OFF state during execution of the VI next time?

  Set the property to "False" node, it will reset.

• Is there a way to put a button on the front panel only when clicked gives a pop-up dialog box with more information on it?

  Hello world

  The simulations that I create are very simple themselves but are intended to use in the classroom to help students learn more about the proven theory.  I hope to be able to place a 'help' or 'other info' button on the front panel that rises wants more info on theory, they can click on it and a pop up appears with background information on it.  It should also have a second button to close it and return to the main façade.  Can anyone lead me in the right direction?

  Thank you!

  Use a structure of the event on the main vi when the button is clicked, launches a "help" void / vi. On the inside of the Sub vi (with the set properties to load the front when it is called, of course), use another structure of the event to wait until then click on the button of the Subvi, you can return to the main VI. Do you need assistance on using the structures of the event?

• Scan of the computer does not work in silent mode of the button on the front panel.

  The machine is the Photosmart all-in-1 6280 on a network of small size and using the HP Solution Center. Basically everthing works fine, but when I use the button on the front panel to scan a document, it seems necessary to walk to the computer to answer a question about whether I want to scan another document until I could walk to the printer/scanner and press the button to scan the following document. Surely, there must be a way to do the scan run in quiet mode so that I don't have to keep clicking OK on the computer every time? I have already disabled the overview of digitization and the prompt for advanced options.

  Oops, forget all that; now I found the setting 'interrogate analyses' which stood on another branch of the installation menus. That solved my problem

• pause button on the front panel

  Hello.

  I try to run synchronous, continuous analog conversion of 2 cards of PXI-6259, and capture the State of the several digital at the same time.  I managed to get everything is configured and working properly, however I have a problem if the user presses the button "pause" on the front panel.

  From what I can tell, acquisitions of data will continue to run in the background (I'm using a task DAQmx and stop was never called).  For my analog inputs, this is not a problem.  However, the digital inputs always generate a ' 200010 - on-board memory overflow error. Due to the limitations of system and/or the bandwidth of the bus, the driver could not read data the device enough fast to follow the flow of the unit. »

  Is it possible to register for an event of user interface that is generated when the user presses the button "pause", so that I can stop the acquisitoin of data before the error occurs?

  Thanks in advance,

  I thought to add my own button "pause" / control, but my users have become accustomed to hitting the pause on the front panel button, and it will be difficult to get them to change.  I guess that the error would remind them :-)

  Well, that's easy to fix - change the appearance of window properties if the toolbar is not visible, while the code runs, and there will be a pause button for your users to click.

  Many of our applications have a function somewhat like this.  My colleague implementation in a very simple way: he put the graphical indicator within a box structure.  Connect a Boolean control "pause" to the structure of the case, and that's it.  Data acquisition runs constantly but will only update the chart when the pause button is false.  This approach might work for you?

• Button of the front panel & remote control questions Qosmio F30-140

  Hello to all users of the Forum and to whom, who prefer Toshiba to a daily activity of s.

  I am owner of laptop Qosmio F30-140 for 7 months. I can say that I m happy with my laptop. But about 2 weeks back, I had some problems, which I can't resolve up to our days.

  I use Windows Defender to protect my PC from alert elements, applications of which I erased by this program once. There after I ve discovered that s keyboard buttons in the library and the remote responds does not and does not control panel. I had tests to recover by Qosmio player recovery CD, but unfortunately all attempts have failed.

  Please help me solve this problem, because I am deprived of my remote control, in which I so need.

  As for you and best regards.

  Hello

  Looks like you have just messed the whole OS.
  Use and relocation of the recovery CD Qosmio Player will not allow Toshiba cotroll buttons and remote control.

  In you case reinstalling the driver would be desirable; Start with Manager common Module, controls, remote control.

  If it does not help the use of CD recovery Toshiba does wonders! ;)

  But note; Don t forget to back up your data because the recovery CD formats the HARD drive!

• Best way to share/update buttons on the front panel

  Hi y ' All!

  I am a beginner in LabVIEW (2 years experience: 1.5 academic year and a team of the FRC and professionnellement.5 of mentoring as a new graduate in a startup).

  We develop an application using LabVIEW which is intended to be user-friendly touch screen and we have so many front-facing button with which we are dealing. In order to make the code more readable in force and easily scalabe, I will like to know if there is an effective way to process orders from the front.

  To illustrate, let's say I have this UI:

  

  

  The real way we propagte these controls is to create a cluster of the reference of all controls (it's where I wish we had LabVIEW 2012-_-) once unbundle that we need in the appropriate section of the code (means it's a large number of sons everywhere...)

  

  So are there better ways to achieve the same goal?

  Thank you!

  I'm talking about a Controller of GUI in this thread. This can give you an idea.

• N6350 Scanner will not scan button on the front panel

  I have configured the HP scanning software and added a shortcut. It will scan from the HP Scanner Software, but no analysis NOT of the scanner. The name of the user's the shortcut there. When I hit the button, is said "Please wait" and the Green LED flashes. But it does not scan.

  Solved. Do you have an another clean install and it worked...

• Create new vi by clicking a button on the front panel

  Hello. I'm quite new with Labview.

  I have to use an if statement to activate a button (I don't know if it is possible or not in LabVIEW) then when the button is enabled for the user must click on the button (allows the button say NEXT) to close that vi and open an another vi to a specific address. I have need to record anything the previous VI that I just need to close and open a new one.

  Does anyone know how to activate a button to get the right answer to an if statement first and also how to close and open the new vi by clicking this button.

  Thank you very much.

  I think that the seal will help you much further.  I have documented if necessary.  If you have any other questions, feel free to ask.

• Front panel locked, but not due to the structure of the event

  Hi it LV community.

  I did a staemachine program that executes an oscilloscope (screenshot of a provided below... the State of the problem). I ran my program yesterday and it worked very well. Then, like a model, a dialog box opens and I just clicked on it in a hurry. now my front hangs as soon as I move the above-mentioned State "the Oscilloscope settings.

  As indicated, I have go a repeat loop that collects successive impulses of my oscilloscope and displays on the front panel (it works fine). In parallel, I have a structure of the event that makes the tail for the real-time feedback of changes to parameters that I placed on the façade (exodus of state change).

  Here's the problem: as soon as I State 'Oscilloscope Settings' using a Boolean button on the front panel for get me there, the front hangs... No event triggered by this point, and even if it did, I already deselected the "Lock panel until the end of the matter for this event" checkbox in the case where the structure menu.

  So WHY is my front lock now? Thoughts anyone?

  Read the detailed help for event structures.

  He urged that a single event structure serve in a VI. There are moments where more can be used effectively, but caution and a thorough understanding of the structure are needed.

  The problem is that you have several structures of the event in the various cases of the state machine and they are set to respond to the same events.

  When the button Set Oscilloscope, the structures of the event in the purchase Menu and home screen States receive the event. The two lock the screen, but only one of these cases may work. It can transfer control to the State of the Oscilloscope settings, but the other event responding to this same event structure maintains the locked Panel.

  The solution is not not to release any of the event. The default value is usually the best setting. The best solution is to spend on an architecture of producer/consumer (events). Who uses two parallel loops. The producer has the one and the only structure of the event and passes orders to consumer loop through a queue.

  Probalby want as the mechanical action on the buttons to lock when you press. Put kiosks inside the respective case of event changed value and local variables becomes unnecessary.

• Watlow DP front panel

  Hello

  Can anyone help. I am currently doing a project for College. Basically, my plan is to use labview to control a temp of DP watlow controller to turn on a heater off the coast. I want only basic as set functions of preforms and read the temperature and possibly graph temperature. I will also put in place a regular thermostat and relay to switch on and switch off the device and use it again the PDD to monitor and graph of this temperature. My project is basically to graphically display the benefits of PID regulation.

  Now, here's my problem. I'm pretty much a perfect beginner when it comes of labview and programming. I downloaded Labview instrument for the DP controller drivers, but I have no idea how to use. I got the connection from my laptop to the watlow via internet but I have no idea on how to get on the cat of my watlow labview. When I opened the drivers of instruments is just a load of Subvi and I don't know what to wire to the place where, or what to use to get a simple button on the front panel by increasing or decreasing the set temperature.

  Any help would be appreciated to massivly

  Thank you

  Hi, Declan,

  Yes, they are the right drivers. I assume you are using LabView 8.0 or later version. Just to help you get started, here is the link which explains the fundamental band of instrument drivers.

  Internally, the VI in an instrument is organized into six categories.

  (1) ' initialize VI"establishes the communication with the instrument and is the first driver of the instrument calls VI

  (2) "set screws" are software routines that configure the instrument to perform specific operations. After calling these VI instrument is ready to take the step.

  (3) ' command screw action/Status' the instrument to perform an action or to get the current status of the instrument or pending operations

  4 "data" screws from the instrument of transfer or date

  (5) "utility" VI run various auxiliary operations, such as reset and self-test

  (6) ' close' close VI ends the connection of the instrument software. It's the last pilot instrument called VI.

  There is a help function (?) the top tablet of your block diagram window, if you click on that and put your cursor on the VI it tells you the function and what it takes to be connected in VI. This should be enough to get you started.

  There are also a few examples to the finder OR example-> entry material / output-> instrumentation drivers-> labview plug-and-play (if you can't find them please install the instruments from hereaggilent) who should give you an idea of how works driver programming and instruments. This should be enough to get you started. I'll try to find you some examples that are related to your project.

  Also if you are in the United Kingdom and needs help with learning LabView programming you can call 01635 523545, and they can organize courses for you.

  Best regards

  Hello Truman,

  Try to reset the DVD Home Theater system and see if it helps.
  In order to reset,
  Unplug the power cord of unity HTS of the socket for a minute.
  Plug it directly to a power outlet and switch on the device.

  If the front panel display does not always illuminate upwards, perform a cold reset, which returns the system parameters, such as the speaker settings and preset stations, factory settings.
  To reset the cold,
  Press the POWER button on the front panel of the unit to turn it on.
  After this, press the button STOP, EJECT and POWER on the system at the same time.
  If the front panel displays works, then, "COLD RESET" will appear on it.

  If the problem is still not resolved, it may be necessary to return the unit for service. Use the following link for a repair facility for your HTS

• Wait for activity on front panel

  Hello

  I have a while loop with a counter (shift register), in which Im can choose how many times its going to count. This loop is used to allow a data in a economy another loop via a local variable to activate it on the VI "write to messurement.

  Now, I wish that my loop counter to count the selected number and then stop, until I press some activate button on the front panel.

  My idea is to use the "wait for activity of façade" in the loop of the meter, to "stop" the loop when the number cunted is reached and then continue, if a key is pressed.

  But I can't really understand how to operate :-(
