Boolean switch rendering time.

Hi all

I have LabView of issue of a signal of my USB-6501. The output signal triggers a relay and turns a solenoid switch.

Currently, I have a Boolean value, implemented as a button where to click to activate the signal, then click on to turn it off. In turn the valve opens and then closes.

I am extremely inexperienced with Labview and was able to find enough to implement, but it is difficult for me to convert what others similar, but different set ups, have made the forum search.

What I have a problem with now change this code in order to have clicking on the Boolean output affects the signal for a while (let's 500ms) and then turned off automatically (without having to set). Basically a pulse. I feel that this would imply the loop any set with a timer, but I'm not sure how to start setting this up.

I have attached my LabView code for you to see. I would appreciate help. Thanks in advance.

I recommend using a Structure of the event.  On the change of Boolean value, you set or reset the output.  Using a registry to offset, you can also set the timeout for the structure of the event.  Then in the timeout, use a Value property (signs) of the Boolean to force a change in value to the Boolean false.  This will result in event of change of Boolean trigger and consequently cause your output turns off.

  • Control relay with Boolean switch using DAQ assistant 9481 - problems

    Sorry for what may be a stupid question but I'm stuck in quicksand.

    I use a relay module 9481 and have two external relays connected lines 0 and 1.

    When I create a digital output 0 line by line, I can run the test inside the express and activate the relay and turn off without problem.

    The generated block DAQ expressed expects a Boolean input of 1 d. (See attached photo).

    I want to connect a Boolean switch relay line disk 0. You can connect live not because the switch is Boolean and the input is Boolean 1 d - I'm a conversation in the pict.

    All plumbing lines display results, the relay never active.

    Any bunch would be greatly appreciated! Thank you

    Mr._Mechanical,

    Welcome to the Forums of switch OR this forum is generally intended for products OR-SWITCH [such as the NI PXI-25xx & NI SCXI-11xx], I think I know the answer to your question.

    I think the reason why it's a failure is the conversion you make generates a table of 16 Boolean [as the 'boolean to (0,1)' function creates a data I16 type] with your data more false data points 15.

    When you try to control the relay, he sees 16 datapoints are you Commander to a single port [channel] and so error out.

    My suggestion would be to use normal DAQmx digital output screw [with, he set up as ' Digital > single channel > single sample > Boolean (1 line) "] rather than the DAQ assistant.

    If you use the daq assistant, simply by using the function 'Building the table' will transform your simple Boolean data point in a Boolean array containing a single element.

    While the DAQ assistant is very easy to use, I recommend that you use the DAQ assistant, because this reduces the features and increases the execution time.

  • How to switch rendering engines?

    I have an application based on the web that is specific to my company. When I run the analysis I have to switch to get it, the renderers to display correctly. Before I did the update today, I used to right click on the tab and choose "Switch rendering engines", then run it. But now that the option is gone when you right-click. I hunted around everywhere to find it, but can not, please let me know as soon as POSSIBLE how to access this feature. Must be able to run to make it work.

  • How do switch you between 2 numeric values using a Boolean switch?

    Hello

    I'm a newbie to labview, so it is perhaps easy to answer.

    I would like to perform a calculation which, according to the test unit, will require a different numeric value to use in the Calc.

    I tried to use a Boolean switch to choose which constant must be used during runtime mode as well for example or 0.01 or 0.02 will be selected. The idea is to labview so insert the constant selected in the calculation and spit out the answer.

    There is only one output on the Boolean toggle switch and not of entry so that I can't work out how to do it. If there were 2 inputs and 1 output it would do the job.

    Thank you

  • How to detect the correct sequence of Boolean switches pushed

    Hello

    My program is all what I want too. However, I need to have the Boolean switches (digital inputs when wired to the equipment) be detected in the right sequence. There are 16 switches on a Board of material. The test subject is displayed 3 colors before hand and the sequence of buttons to push when prompted on the screen with one of the colors, each color pertains to a specific sequence of 4 switches pushed on 16 as quickly as possible. The sequence of buttons remains always the same according to the three colors red, yellow, blue.

    In the program, which is 99% working properly I tried to use a sequence of plate. It will give me a real if I hit the switches correctly - but will also give a real if I hit them back etc... I thought that a flat sequence is read from left to right?

    Then I messed around by using a structured event - the array of switches, pushed index and compare it to a table of values control. I understand how it works, but the correct code is elusive.

    I have attached a picture of program I did but it lacks the proper sequence. (Flat sequence)

    I have included the code for the structured event that I messed with. Don't laugh - I was just making experiences - I've never used a structured sequence before configuration.

    Hope someone can help me.

    Hi Ned,.

    Your producer-consumer model is actually very close to work.  In the original version of screenshot, it seems you are trying to use the structure of sequence to capture the order, but in reality you will capture only the AND logical of all the 4 buttons with no information about the order in which they were pressed.  The structure of sequence does not by itself is waiting for an event to happen inside the frame, it which means that all 4 frames read as fast as the processor moves to their reading - which will be very fast.

    I've made a few changes to your VI and renamed him Rev 1.  See if it makes a little more sense with the notes I made on the front panel.  I also did a different version with a loop simple and some added functionality (-Ko), just in case Your ' e interested in another way to look at it.

  • I used even to make the Blurays for a long time, with success, with no problems. Today, on my current project (.iso file estimated size ~ 19 GB) MENUS rendering time is reported as 31 + Hrs. Is this OK, or is there a problem?

    My system: 2013 Mac Pro: Core, 64 GB of Ram, two GPU of D700 12 / 3GB. I was creating an ISO image file using ENCORE 6. I am currently using the latest ADOBE CC system.

    The menu on which rendering takes a while has three normal buttons linking to 3 first videos produced. The menu has a long file AUDIO (about 90 minutes) as an attachment.

    After letting the rendering process to continue for 4 hours, on the audit of the progress window, progress bars seemed not to be ahead. I waited 2 + hours of overtime and checked again. Progress bars have been in the same place (no deposit). Activity monitor showed that still was still running. At this point, I cancelled the task. Then, I wanted to just MAKE THE MENUS. It is currently running for the 95 + last minutes. Details 'Render' reported ~29.5+ hours as TIME REMAINING. The number of processed IMAGES currently shows ~ 27000 + showing as 169065 in total. The meter for executives of the ongoing transformation to increment of the above stated figure of snapshot of 27000.

    I think that maybe I should let it continue to operate at the end (i.e. 30 hours of rendering time, if all goes well). Is - this sound NORMAL?

    Any advice will be appreciated.

    Never tried such an audio file for a long time. Are you sure that there is no video movement in this menu?

    What format is the audio file?

  • How to speed up rendering time on ADOBE premiere pro cc?

    I go to adode first pro to adobe first pro CC and now render time got more slowly, since a render time of 30 min (adobe PR) 2: rendering time (Adobe PR CC) what to do?

    You have ALSO improved last month, to Win10. Which could contribute to the issue of speed too.

    To speed up the rendering, get a faster processor with more cores and more clock speed, get more memory (up to 32 GB), change the AMD video card for a videocard of nVidia GTX 9xx and only use SSDS.

  • Rendering time 12 times faster or slower depending on GPU accelerated effects?

    Hello world!

    I use first Pro CC on a new powerful enough Windows system (a young i7 cpu, 64 GB of ram, double cards GTX 760) and just test its rendering performance.

    I have a 20 minute video with 6-7 video effects applied (on its whole length), only for testing purposes. All these effects are GPU accelerated, chosen from the built-in PP. I also enabled the GPU acceleration for the EMT (Mercury playback engine) in the project settings and the render bar in the upper part of the chronology is completely yellow (not red), so that everything seems nice and good to go. I then export it and it's pretty fast, rendering time is about 12 times faster than when I export in Disabling the GPU acceleration in the project settings (by selecting the 'Software MPE' option only). So everything looks good so far.

    Now, when I add to clip an single effect which is NOT a GPU accelerated (from built-in PP ones) I noticed that the bar made totally blushed and time of export (always with active MEPS GPU) is now the same as if I exported with the option "software MPE only! (approximately 12 times slower than before!).

    Is this "normal" guys? or am I missing something here? I mean, one effect 'enough' to slow down the entire accelerated by GPU export process? (and essentially "cancellation" of all the benefits of GPU acceleration speed)?

    If anyone can help? Thanks in advance!

    I'd say it's normal.  Indeed, with the addition of this effect, I could even expect to take more than software mode without this effect, you add in the calculation process.

  • AE CS4, plugin Keylight, rendering time and specification of the machine

    I do a show which takes 15-20 minutes.  We use a wall of chroma chroma (green) and various images and graphics in the background.  It's a show of several camera.

    The chroma chroma Keylight for AE plugin is amazing. The finished file looked very good, but it really took a lot of time to render.  More than 25 minutes for a test of a minute sequence.  If I had to make it 15-20 minutes, it could take all day.  Is this normal for these long there rendered moments on clips matched with this plugin?

    My machine is an older machine.  Win XP SP3, HP/compaq dc7600, Duo core, both 3.4 GHz, 3 GB of RAM.  If I had to update this machine, which would be optimal for the shortest rendering time?

    I found a quantity of decent info on how to use the plugin, but not big thing on recommended card machine or times normal.  Where can I find more information on the card of what machine are needed to take full advantage of tools and plugins of EI?

    Thank you

    MMH, Yes, it's still ambiguous to advise on the matter. For your business a Core2Duo should be just fine. Just make sure it is later a (8600 E currently). I wouldn't bother with a Core2Quad in your situation - if there is no hope of improvement, what be soon, it's a bit pointless to invest in a more expensive processor and motherboard. Given the fast-paced development cycles, you buy a computer for the next 2 or 3 years and already in a few months to not consider any worthy material updates. At best, so I'd go for a new AMD Phenom II X 4 because it's much cheaper while offering better performance (current quads of intel are a little behind). Yet, would be exaggerated, especially if we consider that "crunchy" all can be more important for you, to get fast feedback while you work more predictable rendering times. The performance by heart is less about quad systems, they burn only if you use the hearts of all time, that your proposed combination would not. AE and many plug-ins don't are not especially optimized in terms of multithreading and if you use the option to make several images at the same time would compensate, is another matter. Definitely get these 8 GB of RAM and Vista 64 Business or Ultimate, so you can max on the memory of EI usage and are on the right side, when future versions are going to 64-bit. For the graphics card, settle on a GeForce normal 275 / 285, not a multi-GPU as 295 card. With regard to the suggestions of the brand - Dell and HP are trustworthy, but not the cheapest. I could recommend other brands are specific to the Germany / Europe, so he can't help you. also, if you know a good computer guy, think about him having to build a custom machine. This will shave a little money here and there, because you can order the individual components of those who sell at the lowest price. I went like that with my Core7i and was thus able to save almost 500 Euros compared to these sellers of stock...

  • Total rendering time is reduced by cutting of items?

    Know that I can run experiments to answer this question, but also know that a number of people here have already responded to this.  Scanned the FAQ and done research, but never found an answer to this specific question.   I think it is safe to say that stability can be achieved by dividing a long clip, for example one an hour.  But it is total time reduced rendering?

    Take a 1 h project as our example: If you return the full 1 hour it will take X amount of time. If divide you it in half and make no other changes, your time will be X / 2 for each. X / 2 x 2 is always equal to X, or so close as to not make any real difference. You'll spend more time opening upward both halves and hit Render, that you want to save. Now, as the rendering time is dependent on CPU, there could be a slight advantage (more efficient use of a CPU) to do it in segments. As my QuadCore never maxes, I doubt I could tell the difference except with a stopwatch - clock on the wall is probably not specific enough. If I'm on my dual Quad machine, I'm not even sure that a mechanical stopwatch show. If you have a slower processor, things could be different enough, as County, but still not it.

    It looks like to use pure vs RAM virtual memory in Windows, on a fast machine. Yes, there is a difference in speed, but a human being would be hard-pressed to really make a difference. Enter the virtual memory on a slow machine with very slow I/o and then you will really see the difference.

    Overall workability likely to improve with the project split. There you will probably see a speed difference and also power change crashes more comfortably with less of a concern to the wire. Rendering time, however, will not be enough difference for a SIP of coffee, once you add the pieces to be rendered.

  • Boolean switch that are timed

    I need to order a heating appliance to be switched on for 60 seconds and then be off for 120 seconds, and then the operation be repeated for a number of cycles. My main loop works continuously with a delay of 50 milliseconds, and needs a Boolean signal from switch continuously, so there is no possibility to place a hold or time out function in this loop. When I try to call a Subvi, which has a delay, the output of my main loop would be delayed. Anyone would be able to recommend me in the right direction.

    Do it like that. It initializes the value False, after time, happening to True, and so on.

    This could use some cleaning with nodes Select, but it does the job. The result is False for 120, then True for 60 seconds, rinse and repeat.
