PID Setpoint profile using Minutes instead of seconds

• Profile of PID setpoint

  Hello guys

  I work on the project using the NI USB 6251 case and labview. I use VI profile for setpoint PID to make setpoint 7 volts at t = 0 and 0 Volt at t = 5, then back to 7V to t = 10 and 0V again at 15, repeatedly (7V every 10 seconds) until I have stop the execution of the VI. any ideas?

  Thank you for your help

  When you set the profile to use, simply "toggle" the "reset" and the function will start the profile, as t = 0. This example shows how you can start by pressing a button:

  C:\Program Files (x 86) \National Instruments\LabVIEW 2015\examples\control\PID\Setpoint profile Simulator.vi

  However, if you really want to restart automatically, wire "full profile?" via a shift register to 'reset '? entry and the profile will be repeated continuously. This another example is exactly that:

  C:\Program Files (x 86) \National Instruments\LabVIEW 2015\examples\control\PID\Setpoint profile with hourly so that lift and Falling.vi

  Furthermore, if you look in this folder:

  C:\Program Files (x 86) \National Instruments\LabVIEW 2015\examples\control\PID

  You will see several example that will be of interest to you to learn how to use LabVIEW and control functions.

  Hope this helps,

• I'm unable to start Firefox. To get the message that it is already running. Cannot find my profile using '% APPDATA%\Mozilla\Firefox\Profiles| '. What should I do

  I'm unable to start Firefox. To get the message that it is already running. Cannot find my profile using '% APPDATA%\Mozilla\Firefox\Profiles| '. Restarting my computer did not help. Because I had this problem I also noticed that all my favorites that I had copied in Windows Internet Explorer also disappeared. I use Firefox as my main search engine and usually do not use Internet Explorer. I am running Windows 7 on my machine.

• How can I make firefox use http instead of https?

  In internet business, it is problematic to use https.
  However firefox by default always to https connections (for example during a google image search in the toolbar search, or when you type an address bar starting with "www"); so always raise an alert page "this connection is untrusted" and make me go the address bar manually and change the 'https' in the 'http'.
  In Google Chrome and Internet Explorer, it is very easy to install the browser to use http instead of https protocol. However, I can't find this option in firefox. Any ideas?

  There are two different parameters involved:

  Address bar Autofill

  If you used HTTPS to a site before, the AutoFill feature to Firefox address bar will prefer the HTTPS address. If you don't mind by selecting from the drop-down instead, or just type the address in full, you can disable AutoFill the address bar. Here's how:

  (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (2) in the filter box, type or paste the AutoFill and make a pause so that the list is filtered

  (3) double-click browser.urlbar.autoFill from true to false.

  Search from the address bar

  About the address bar search, you can change the URL used by the 'key word' service. Please see this thread for links: unable to connect to the proxy because of the automatic https.

  That solve it?

• I can't use a website should I use with Firefox 5.0. So, I need to uninstall and go back to 3.5 or 3.6. Please notify. Also, my control panel blocks from Windows Explorer a PMP. That's why I use Firefox instead. Thanks for any help!

  I thought it would be FAFSA is causing your problem.

  Install Portable Firefox 3.6.x on your hard drive to a Web site. This will not affect any of your current Firefox installation.

• Using DVI instead of VGA on the Port Replicator - Tecra A9

  I have a port replicator toshiba that I use with my laptop Tecra A9, currently I have a vga cable to run the external monitor, but I prefer to use DVI instead, but I can't make it work.

  Is there a setting somewhere that I have to activate? or should it work?

  See you soon

  Ash.

  Hello

  As much as I know there nothing that you must set for the use of the DVI port. The question is how you use it. Using a DVI - VGA adapter?

• What are the parameters? How are Variables differenet? Why we can not use variables to pass data to one sequnece to another? What is the advantage to use parameters instead of Variables?

  Hi all

  I am new to TestStand. Still in the learning process.

  What are the parameters? How are Variables differenet? Why we can not use variables to pass data to one sequnece to another? What is the advantage to use parameters instead of Variables?

  Thanks in advance,

  I'm sorry... I discovered that... its not at all possible to pass data to another sequence using variables... it must be through settings... once again I apologize for the display of such a stupid question

• Why the continuous measurement and Logging in LabVIEW 2012 Project uses strings instead of Enums and orders from the queue?

  Hello!

  I noticed that the continuous measurement and a project in LabVIEW 2012 Logging using chains instead of enums and orders from the queue. I wonder if there is a good reason for it?

  Kind regards

  Anguel

  First, string vs enum debate is probably the version of LabVIEW vim vs emacs. There are good arguments on both sides, and I doubt that there is always a "winner".

  A brief summary of our reasoning for the current state of the project examples:

  1. We used enums for the state machine because it is self-contained. A state machine will never tell himself to enter a State, he does not know. Knowing (as the programmer) all possible States with the help of an enum allows you to enlist the compiler in order to help us avoid mistakes to change the time (because you can't quite out an enum and LabVIEW can be said if you are not covering all cases to a structure of the case, etc..).

     Enums provide greater protection and rigidity by ensuring all withdrew at the time of publishing. This is often the 'default' recommendation that we do.

  2. We used strings for messages in queue manager because the producer of message and the message handler could be independent processes that are reused or traded. Channels avoid the need for the compiler to be able to connect the orders and push this responsibility to the programmer. This allows you to develop some sub-components independently as long as you agree to a series of channel commands that you can manage - you need not to share a file 'messages.ctl' or 'states.ctl '. It is conceivable a loop of message management a message it does not, how you can decide to either silently ignore it or will trigger an error (as we do in the model). The strings make it also easier if you want to swap the queues of LabVIEW outside by a TCP implementation for network vacilitate or intra-Processuse communication where the other end may or may not be written in LabVIEW.

     Channels to provide more flexibility (that is, you can add new commands to an existing via plugins system, you can pass parameters as part of the string, etc.) at the expense of pushing her potential errors at run time and to put more responsibility on the programmer.

  3. The actor's gifts frame a 3rd option - using classes such as messages. For me, it combines many of the advantages of these two enumerations (strictly typed, change errors) and strings (flexible and scalable), but with the disadvantage of being somewhat less transparent (you understand OO, be comfortable to navigate through a multitude of screws, legacy of understanding, etc.).

  I don't know there are other reasons, others to the breast OR had or seen as we validated models and examples of projects in-house, but here are my reasons. We know that we can not design for each situation there - our goal is to get useful models against new users to make them aware of what well thought LabVIEW programs are similar to experienced users know their applications better and I hope they do not hesitate to change what we provide or create their own designs, when they feel it's necessary. (On a side note, please share what you come up with - a community of experts sharing models would be really useful to us all LabVIEW users).

  Best regards

• How can I send five simple characters (P, H, O, T, O) using ComWrt, instead of sending a single string?

  The manual of instrument mentioned that "for switch mode remote"P","H""O""T","O"are sent as single characters and not as a single string". How can I send simple characters using the Serial Port, rather than send a single string?

  I have no CVI installed on this pc, and in the past, I used VISA instead of the ComWrt. If you know how to write a string, then I don't see where is your problem. You write only 5 channels instead of one--each with a single character.

  You can post to the ICB card if you have problems with C.

• Why and how 'create a profile using the e-mail icon?

  When I try to send a screenshot of a web page, and after that I'm going to "email recipient" a small screen appears and tells me that "no profiles have been created.  To create a profile use the mail Control Panel icon.  What this means and how can I do?  I use outlook express and can not send another email, just not screenshots of web pages.  UPS used to before.  I recently "upgraded" in IE8.  Thank you!

  Check in Internet Options as your default mail Outlook Express Manager

• Can I remove internet explore and use chrome instead?

  Can I remove internet explore and use chrome instead? That is, crashes, to stop, resarts and slows my computor. I installed Google Chrome and have had no more problems. It opens and closes when I want it and going to the Web pages as I type in without hesitation. I like windows 7, I only have a problem with Internet Explore. It also caused changes in my modem. I need to uninstall the software and reinstall to get it working again. IO would open that is and get a message that says "no internet access - check your settings, I thought it was a virus at some point. As soon as I started using Chrome, everything worked again. That is also caused problems with my printer and home network. I don't mind that is being stored in a file, I don't want to work and make changes to my computer I'm not an it expert by any means. I restored my pc to an earlier time and new conditions of factory several times in the past year (I bought the HP pc new in December 2010).

  It is not really a way to remove Internet Explorer.  I have not heard of the type of problems, you had with IE, but if you prefer Chrome and who works for you, all you need to do is to make Chrome the default browser.  I use Firefox and make it my default browser.  Once you make Chrome default you just leave Internet Explorer installed but it won't get used.  Following comes the site help Chrome and tells how to do it by default: http://support.google.com/chrome/bin/answer.py?hl=en&answer=95417
