Control valve that opens and closes linearly using DSC

I have to create a control valve that opens and closes linearly.I want to view its variation in percentage wise in the graphical form which uses DSC module.

Hi Gerardjoe,
I'm not sure that I completely understand what you're trying to do. In the DSC modules, the valves (2D and 3D) are simply boolean indicators.
One thing you could do, to see some sort of a percentage change, would be to have an indicator such as a vertical fill slide. Here, you would put a number between 0-100.
Then, you could have a comparison, such that if this value was over, say, 60, then the boolean value would be true and the valve would turn on. Else, the value would be false and the valve would stay false.
I hope that this answers your question; if I did not understand correctly, please do respond and clarify.

  • How do I control a servo-valve to open and close with Dasylab?

    I am currently using a servo-valve to run an endurance test and would like to control it to open a close  at a set frequency rate and set pressure rate (6000psi). Is there a controller that I can use to do that?  I am using Dasylab with a NI Daq board and I get the pressure and flow readings from the analog to digital signals correctly but to actually control a servo which is powered with and external power supply to provide 25VDC.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

    It would be unwise to use DASYLAb to close a loop on a servovalve.
    The best way to do that would be to buy a analog PID controller board, MOOG and Parker sells those, and use an anaqlog output from the NI card to controll it.
    We did many tests using this way.
    There are also other option like servo-controllers that could perform many tasks, like FG, conditioning, limits, and profiles and then use DASYLAb for Data acquisition.
    The price for this solution would be of course higher.

  • I AM MAD THAT I CANT OPEN AND CLOSE iTUNES USING COMMAND-1

    people used to be able to press command+1 and open the iTunes window or close it and now you can't
    keyboard shortcuts still says you can
    this is inconsistent and annoying becsuae I love keyboard shortcuts and I like being able to close my window and open in often without using my mouse

    Well Yoni,

    Go to System Preferences -> Keyboard and Mouse -> Keyboard Shortcuts
    scroll down to Aplication Keybpard Shortcuts and click on it once to Select it.

    Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels.  Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer.  I have a pretty simple system with only a few plug-ins, which are usually not in operation.  I have 12GB of RAM in my Windows 7 PC.  I could illustrate these problems with screen shots if you would tell me how to submit screen shots.  Otherwise I will try to describe the problems in words.
    The problem is clearly cumulative, growing worse as usage time passes.  Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond.   In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces  (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
    To experiment I created a new catalog of 1100 images.  After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size  images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
    I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data.  (I have a screen shot to show this.)  CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
    Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong.  I could also send screen shots of this data.
    At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR.  This is not normal.  I hope you can find the cause, and then the solution.  If you would like to see my screen shots, tell me how to submit them.

  • Open and close posting period authorization control TCODE: S_ALR_87003642

    HI All,
    Is there any chance to control the user to open and close another company code posting period variant in TCODE: S_ALR_87003642.
    In our system we are using the same client for different countries. So user can able to change the other country company code posting periods.
    We would like to control either on the country (or) organizational unit(company code) (or) posting period variant so that user can only open/close  their country / company code posting periods.
    Our present authorization role for open and close posting period contain the auth.Obj. : S_TABU_DIS.
    Please share your knowledge if you come across this problem..
    Thanks in advance..

    Hey Sandhya,
    Congratz, this can be done using linbe item authorization with the object S_TABU_LIN.
    Field ORG_CRIT - Value 02
    Field ORG_FIeld1 - Value ZT001B
    We have successfully done it in our client.
    You need to contact your BASIS consultant for this.
    Thanks,

  • Is there a remote app that will let me open and close programs on my iMac

    Hi There,
    I know that I can use the Apple Inc "Remote App" to control my iTunes on my iMac - and I really like it for when I am not right at my computer, but I have to have iTunes open on my iMac before I can use it which is a bit of a pain to have to think "Am I going to use iTunes today?" or to run off to my office at the other end of my house when I decide I want music through my speakers and so my question is thus.
    Is there a remote app that I can download for iPhone or even iPad lets you open and close programs on your iMac when you are not actually sitting at it. So say I want to open iTunes on my iMac i would do the following
    1: Open the remote app on my device (either iPhone or iPad)
    2: See a representation of iMac screen on that device (cut down for iPhone)
    3: Chose the program I want (iTunes in this case) and it will open on my iMac allowing me to begin using the program remotely on my remote device.
    I am not talking about remote desktop or anything here (I don't want to do complicated things on it) just be able to open programs like iTunes so I can have the music play through my home speaker system without having to have all of my programs already running on my mac incase I decide to use them

  • Trackpad is presenting a bug to open and close windows, mission control, and to move/roll the application (App) up and down.

    Totally out of the blue, my trackpad is presenting a "bug". Every time that I try to open and close my mission control, or in the moments that I move / roll up and downs the Applications Screen, my Mac freezes for less than a second.
    It never suffered any damage (NEVER!)! I am feeling very frustrated because I have no idea about what could cause such problem.
    My MacBook Air is running OS X 10.9.5.
    Any help will be very welcome!

    Well, it all really depends on the custom program and how it was written. Does it have an ActiveX interface? If it does, than that's the easiest way to go. If you put an automation refnum on the fron panel, you can right click and it and choose Select ActiveX Class>Browse. The browser will list all of the ActiveX type libraries that are registered on your system. If you can find one that refers to your custom program, then you should be able to use it's methods and properties to control. If it does not have an ActiveX interface, then things get much more difficult.

    When the phone is locked, you can pull up on the camera icon in the lower right of the screen to access the camera. If you have Control Center enabled in the lock screen, you can also access the camera that way. 

  • IE open and close immediately. Can't fix using many methods.

    A user reports that can't use IE 8 suddenly.
    His PC is Windows 7 Pro sp1 and using Internet Explorer 8.
    Don't know what he did before and he ever tried restore to previous point but no help.
    I've tried the following.
    1. http://support.microsoft.com/kb/967896
       Reset Internet Explorer to its default settings or
       Uninstall and then reinstall Internet Explorer through Turning on/ off windows features.
    2. Use other user like Administrator to open IE. But result is same
    3. Upgrade to IE 11. Still open and close immediately only.
       Repeat step 1 but still not solve.
    4. Downloaded IE 11 and installed manually but it stated that IE 11 was installed. (Had turned off IE to uninstall it through Turning on/ off windows features)
    Asked him to use Chrome but some websites need IE. So he must use IE too.
    Please advise that how to fix it.
    Hope not need to re-install OS.
    Many thnaks.

    1. Are there any traces in Event logs?
    2. Try to delete history in IE
    3. Try to disable add-ons.
    4. If nothing helps, analyze your system with Process Monitor and Process Explorer. Check which programs starts with Autoruns (all programs are from Sysinternals)

    I recently migrated my MacBook from 10.5.8 to 10.6.8, using the Snow Leopard CD I purchased from Apple. Since then I have noticed a strange ozone smell coming from the MacBook in the area where the hinges are to open and close the unit. I was told by Apple that it probably is not serious and is coming from the fans in the MacBook. It is true that the smell/odor is more intense when the fans are working. Apple said I should take the MacBook to an Apple Store to have the hardware checked out. Everything seems to be working correctly. I am backing up automatically wirelessly to a Time Capsule, which I had not done until recently, although I had purchased the Time Capsule in 2009. I have not noticed this odor before. Does anyone suspect something more serious that may be going on?

    You may be smelling it because with the new OS the processor is having to work harder causing it to get hotter then it would with the other OS.  I can't say there is nothing wrong, but what could be happening is just that, it's getting hotter so the fan is spinning faster and moving more air so you are getting more of the smell then you would before.  I would still continue to back it up, and take it to the Apple Store at a Genius Bar and have them look at it to make sure.  Was the computer ever in a smoky environment??

  • Photoshop 12 trial version will open and Close before I can use it

    How can I fix this problem when I open Photoshop Elements 12 it opens and closes immediately?

    Ralph Hoover
    You have posted in the wrong Adobe Forum. If you have Photoshop Elements 12, you should be posting in the Adobe Photoshop Elements Forum, not the Adobe Premiere Elements Forum (video editing).
    http://forums.adobe.com/community/photoshop_elements
    Either repost your question or wait for a moderator to see your thread and place it in the appropriate forum.
    Some questions to think about...
    a. How are you opening the program? From the desktop icon? If so, how far do you get....do you get the Welcome Screen and does it stay open? Is it only when you hit Welcome Screen Organizer or Editor Tab that everything closes/disappears?
    b. What computer operating system are you running your Photoshop Elements 10 on? What do your computer resources look like? Is your Photoshop Elements 12 issue "it never worked before" or "it worked before but not now"?
    Lots more questions. But lots more details needed.
