How to implement multiple tasks (e.g., PID) in parallel?


I know there must be some questions like this in this forum, and I tried to find for a while but got some what I want. My project is a little urgent that I post this question for a few instant suggestions...

As the topic says, I have several devices, say energy suppliers, and I must adjust their power automatically and independently.

Although the number of devices is eight for the moment, but I prefer not to fix the number, otherwise said, I want to scale or increase the number of device dynamically.

As a first step, I am very stupid to put the in the loop for...

I was wondering if the activation of parallelism can deal with my problem, but soon, I knew that each appellant VI data spaces are mixed upward...

I'm stuck on how to book space for reentrant data...

The last one on my mind is the VI open to the outside at the beginning of the control and take advantage of VI references...

But I have not implemented the method, there may be some other thorny issue on this way...

Is there a way to sovle this kind of problem?

Hi William,.

PID functions support several control loops, just read the Help for functions!

No need for this loop FOR (which is simply wrong here)!

    Hello LabVIEW Masters!

    I have a project which includes control and searching for information on a PROBER. One of the difficulties I have now is how to implement a WAFER card using LabVIEW. According to the requirements of my client, the element of pads varies between 6 k and 23 k.

  • How can I use process explore check PID 1176 60% CPU svchost.exe? Help, please.

    As the title, how can I use process Explorer to check PID 1176 60% CPU svchost.exe? Help, please.

    The task manager has PID 1176-60% CPU, all the time, which I believe is the reason my pc works so slow.

    How to use Exp Pro to know what is actually using 60% of my cpu, via svchost 1176 PID?

    I found the Exp Pro Geek guide - but are struggling to pass for a non geek.

    Using Vista 32 bit.

    Thanks in advance for any answers.

    Process explore uses more resources than svchost, it works automatically using a lot of memory. Anyway, the open task

    Mgr, locate the svchost, on the location of TI/properties/open a file. You will find that it is a service of microsoft.

    The drain is usually in BITS, try to go to run, or cmd, type: services.msc in msc, locate BITS, on it, open,

  • How to implement the process of climbing BPM 11 g?

    Hi Experts,

    Can any help with process step by step how to implement climbing for 3 levels...

    For example, User1 doesn't complete the task at some time say 1 day then this task must be wound to its Director Say User2 and if is not finish it even then it must be the second Director of level for 1 day as well for the third level manager.

    Where as one when user 1 task is up to the manager (User2) then user 1 tasks should be sent to the User2, even if its value from table.

    Please please experts throw some idea on this with an example...

    Kind regards

    Hi Pavan,

    There are couple ways to do this. This is the very detailed description of what you would do if you want to set your climbing inside the process using the timer to limit events.

    1. Add three interactive activities and put them in three roles representing the roles for your users 1, 2 and 3.
    2. Add a "Timer intercept the event" on the edge of your Interactive activity for your user 1. Associate the new timer event with Interactive activity for your user 2. This will create a new event of border and climbing you want for the user 1.
    3. the name of the new event to limit 'Question degenerate'-> in the "Application" tab, define the new event of the timer limit as an event interrupting-> specify the range to be "1 d" (one day).
    4. in the same way, add another event of the timer limit interruption between your interactive for user 2 and 3 activities.

    I could have missed something, but it looks like your table is just a process data object variable that will be made as part of the payload with the work item instance when he travels through the process.

    For human tasks for user 2 and user 3, you must assign the task to the Manager of the previous participant.

    Hope this helps,

    I don't know what you're asking.

    AirPort Extreme is a wireless router.

    A Time Capsule airport is an AirPort Extreme with a built-in hard drive for data storage.

    An iMac is a Mac computer.

    An iMac is not a wireless router, so he is unable to perform the functions of a wireless router.

  • I want to prevent access to the ' topic: support ' page. How to accomplish this task?

    I want to prevent access to the ' topic: support ' page. How to accomplish this task?

    You must create the userContent.css file and possibly the record chrome as well if they do not yet exist.
    Note that the names are case-sensitive.

    • Create the folder chrome (lowercase) in the .default < xxxxxxxx > profile folder if the folder does not exist
    • Use a text editor like Notepad to create a file userContent.css (new) in the folder chrome (file name is case sensitive)
    • Paste the code into the userContent.css file in the Editor window
    • Make sure that you select "All files" and not "text files" when you save the file via "save file as" in the text editor as userContent.css.
      Otherwise, Windows can add a hidden .txt file extension and you end up with one does not not userContent.css.txt file
  • How to stop multiple self-switching to the address bar every time I open a new tab and try typing something anywhere outside the address bar?

    How to stop multiple self-switching to the address bar every time I open a new tab and try typing something anywhere outside the address bar? As something just wants me to use this integrated search when you type something non-Web-address in the address bar and press to enter. And the most ridiculous thing is that happens repeatedly on as every second, as I just got off the address bar and start typing again, but still he passes me in the address bar, then 3, 4 times like that. And the result is that I don't see the address of this page.

    I think that its has something to do with my AVG Antivirus, because it started the same time a Nation AVG started to appear in each new tab I opened (and which is irritating as me, I've read here on and it seems that the only solution is to completely reinstall Firefox, but I don't want to lose all my settings) but when I type something in the address bar and press enter It opens the search results in Google.

    Please try to help me, I love Firefox but I have to switch to Chrome until I fix this.

    Thanks in advance

    First of all, please update Firefox 32. 22 is no longer support is not safe. So, let us know if you still have this problem. Update Firefox to the latest version

  • Someone knows how to change multiple 12.3 items?

    Just moved to a MAC from a PC and I can not understand how to change the type of media from his HOME to FILM or TV SHOW.  I can change a file one at a time, but when I try to change several items, nothing happens.  Is there a way to fix this?

    Do you know how to select multiple items at the same time on a list of items in iTunes?  View the library using the view for a regular list with columns.  For your movie library, it is the view of list of films .

    To select multiple items that are on the list, select the first item, hold down the SHIFT key and select the last item.  The two points that you clicked and all the elements between them are selected at the same time.  Make a selection right click and get information.

    To select multiple items that are not in the list, press the command and Option keys and click on the selected items.  All clicked items remain selected.  To deselect an item, click on an item selected (with the two keys).  Make a selection right click and get information.

    You can use these two methods consecutively.  For example, select the songs listed together, most other distinct songs. Or select the listed together songs and deselect any of them.
