• (I hope) Simple problem with time delay

  Hey people,

  I am a neophyte of labview and I have a program (see table) on the screen I use to Flash one of the three signs a pressure switch is released. There is a detection device of time between the pressure switch (run through a data acquisition) and the flashing of the sign on the screen; However, when I use a nonzero value for the delay, the acquisition of data appears to trigger after a variable duration after the button is released, and THEN the delay occurs. If I don't use any delay, acquiring data reliable triggers immediately after the switch is released (and therefore the sign flashes immediately as well).

  I can't understand why the DAQ does not trigger immediately in all cases, regardless of the value of the elapsed time. The only thing I can think of that could have an impact on is the computer I do turn it through is dated (2 Ghz P4 with 512 MB of RAM), but it's not as if it is a program that is complicated... Please help! Thank you!

  The stacked sequence right click and "replace with flat sequence. The flat sequence right click and 'delete the sequence '.

  You have a race condition between val Trig and local of it. Wire directly to the loop to make sure that it is this happening val trig that you use and not the previous races.

• helps the Timer.delay

  I tried to get more information on the use of this command.

  I get the timer (var someTimer:Timer new timer (1000, 1))

  the timer will delay calling a function for a second, once.

  In other examples I've seen the use of

  someTimer.delay = 150

  The timer has already a delay of 1 second (1000).

  Is - this delay County substitute (1000) with a new delay (150)?

  OR

  He puts a delay (150) before it triggers the timer (in 1000)

  IF its what I'm not clear on why you would want/need of a delay on the clock

  (have a timer on a timer)

  OR

  I'm wrong on both accounts, and I really need help! =]

  Someone can help me to understand better, or have links to a place that would be?

  Thank you

  It is changing the delay to 1000ms to 150ms IF 1000 ms did not occur when the delay is changed.  otherwise, your timer event will trigger its an event and change the delay won't hurt.

• Help with Time Machine

  Although I've owned a mac for years, I started using Time Machine a few months ago only.

  For two weeks, I said that my backup disk was full. Today, I got the message that the backup failed and that yesterday was the most recent upward. a double click on the backup disk, I see the records dating back to November. However, when I get Time machine, I can only highlight yesterday.

  So, a few questions.

  1. the November record is really an existing back-up? Why do I see there, but not in Time Machine?

  2. I have several external hard drives that I use for Time Machine and I am interested in finding someone to help me with the best solution to achieve my goal. That is, to remove the 300 GB of photos I have on my internal hard drive to an external hard drive, while still supporting upward from my internal hard drive and a multimedia hard drive for Time Machine.

  I hope I can say this is not confusing.

  I have an internal 500 GB running 10.11.1 HD because I have pictures of some 300 GB internal hard disk, I only 6.66 GB of available space.

  I have 3 external drives available that I can use for the back upward. 1 TB, I got for Christmas and is not used for anything and 2 500 GB HDs... one of them is currently used for Time Machine. The other has a backup is no longer necessary, so I can be erased.

  In addition to using Time Machine to back up, I also pay a monthly fee for Crash Plan. Even though this was my home folder files, it does not back up the operating system. I can, however, point it to back up an external hard drive.

  Finally, these are my questions. To free up space on my internal hard drive, can I (should) move the photos off my internal HD (I don't use iphoto) and put them on an external HD and then have my internal HD and HD with photos backed up with TM? Would it not be better to transfer my photos on a 500 GB HD and then use the 1 TB (without this partitioning) to back up both the internal and external HDs?

  I hope that what I am asking is logical. Thanks to all those who want to take part of my ramblings and give a meaning to me.

  Respectfully,.

  Cayleen

  What I do with my Mac sounds a bit like what you ask to do with yours. I have:

  -Photos and movies on an external drive (500 GB on a 2 TB disk)

  -The rest of my data on the drive internal (approximately 300 GB on a 1 TB drive

  -The internal and external are saved on a third drive (3 TB) used for Time Machine.

  Everything works very well.

• need a little help with time calculation

  Hello

  I tried to implement oauth2 and youtube api. I can connect and can recover the access_token and other oauth required as expires_in json values.

  What I'm trying to do is drive if my access token is valid or not before making another call to their api - youtube gives a value - expires_in that normally contains 3600, which I suppose is seconds. I'm trying to add this time now using clock_gettime(), but I don't get correct values for my calculation - nowTime + expiresInt.

  Anyone can point out the problem with my code please? It could be a bad way to do it, but I thought that I spent a few hours on this subject before asking for help.

  Thank you.

  token = c.value("access_token").toString().toStdString();
      refreshtoken = c.value("refresh_token").toString().toStdString();
      saveValueFor("access_token", QString::fromStdString(token));
      string expires = c.value("expires_in").toString().toStdString();
      saveValueFor("refresh_token", QString::fromStdString(refreshtoken));
      struct timespec* start;
      clock_gettime(CLOCK_REALTIME, start);
      int nowTime = start->tv_sec;
      std::stringstream str(expires);
      int expiresInt;
      str >> expiresInt;
      nowTime += expiresInt;
      stringstream nowTimeString;//create a stringstream
      nowTimeString << nowTime;//add number to the stream
  

  Now you install milliseconds and seconds.

  ) ;

  Some examples of data for my paintings is as below.
  

  INSERT INTO user_info VALUES( 'u1', to_date('9/17/2009 20:00','MM/DD/YYYY mi:ss'), -2 );

  You can do this by adding a clause of "HAVING" as shown below. However, with your test defined data it returns ZERO rows because for all users of the MAX (DATEPOST) IS LESS than MAX (LOGIN_DATE)

  SELECT     USER_ID
  FROM
  (
       SELECT     USER_ID
       ,     DENSE_RANK() OVER (ORDER BY POST_LOGIN_DIFF) RNK
       FROM
       (
            SELECT     USER_INFO.USER_ID
            ,     MAX(DATEPOST) - MAX(LOGIN_DATE) AS POST_LOGIN_DIFF
            FROM     USER_INFO
            JOIN     POST_TABLE     ON POST_TABLE.USER_ID = USER_INFO.USER_ID
            GROUP BY USER_INFO.USER_ID
            HAVING      MAX(DATEPOST) > MAX(LOGIN_DATE)

• Need help with timer

  So I want to create a timer that displays an image after 6 seconds. Here is an example of my code:

  var timer1:Timer;
              //start handleTimerTick function after 1 second
              timer1 = new Timer(1000);
  
              timer1.addEventListener(TimerEvent.TIMER,handleTimerTick);
              timer1.start();
  
          private function handleTimerTick():void
          {
              this.addChild(icon);
          }
  

  but the right icon wouldn't show. Any help? Or are there better ways to do this?

  I don't know if it's a typo or not, but the function should be:

  handleTimerTick(e:TimerEvent):void
  

  aside from that, nothing seems to be wrong. looks like your icon code?

• New to Ae, need help with time remapping (tutorial anywhere?)

  I am very very big thing back to Ae (CS4) and I was with Premiere Pro CS4 to edit a video, but I need to speed up, but as many of you may know, when you use time remapping in Pr, the sound isn't sync.  However when you do it in Ae, it does.  Then...

  What I'm trying to do is to let the clip I am going for a bit of editing time, then gradually increase the speed to 250% of the original over six seconds, stay 250% for some time, and then gradually in the course of about six seconds to 100% of the original speed.

  I'm kind of having trouble finding how to use Ae well.  There are a lot of easy to understand tutorials out there for Pr, but I can't really find any good for Ae.

  You use the time remapping effect. In fact, when you enable TR, you will notice that the duration of the layer is not limited to the original boundaries more. You can extend beyond the layer's original point.

  So, what you want to do is to keep the TR keyframe at the point layer zero to a value of zero. Set a keyframe second point 06:00 of the layer, with a value of about 14:00 (if possible, because maybe the original clip has no more of any material). You did it like that because if you show 14 seconds of video in a six-second segment, the playback speed is about 250 percent speed. You can do better than 'roughly', but this would require using the speed graph...

  For the real variable speed to set the first keyframe (that at 0:00) to perform a "easy ease on", so the speed ramps up gradually (what means "mitigation" for any property). Setting speed to 100% can be reached at justwith degree sense, but to familiarize themselves with the speed graph will make much more accurate. I say common sense, because if you have a keyframe of a code value of time from 14:00 to 06:00, then a possible way to get back to 100% is to show four seconds of material in the four seconds left (in condition, once again, that your source material has something to 18:00). As you can see, TR needs abundant "handles" (IE, additional documents in the source layer) to work at its 'best.

• Motor control with time delay

  
  

  Hello!

  Note that you must put in logic before you run the forloop, since the trip from 0 mm and 0 mm resolution is not a good thing to run.

• PID control with big delay in the process variable

  Hello

  My goal is to control the temperature via a valve and heat exchanger. I proceeded variable (temperature) measured from a hose. This temperature should be raised a few degrees with a heat exchanger. So basically I need to order a valve that allows the water to flow through the heat exchanger to raise the temperature to the desired level.

  My original plan was to use a base PID regulation to operate the dispenser. However, it is about 0.5 to 1 minute of delay time in the temperature probe after I opened the valve, which increases the temperature. This leads to a situation where the PID regulation valve fully open during this period (trying to get the temperature rise). Then once the temperature begins to rise it fires quite quickly. PID begins turning the tap off almost immediately, but because of the time delay in the sensor, the temperature exceeds seriously. This led to severe oscillation and at worst unstable processes. I tried to adjust the PID control to "predict" the timer to close the valve in advance to minimize the excess, but failed.

  I would appreciate if anyone has any ideas how to make this type of control with Labview PID functions. I also wonder if there is a better type of control procedure for this scenario as a PID control?

  -Lars

  This is a very common situation in the heating control, and generally PID can be adjusted to make it work. How do you do the tuning? If you do it by trial and errors, you have little chance to succeed. For a slow process with time delay, I like to use the method Cohen Coons, or similar open Ziegler-Nichols-loop method. The idea is that you temporarily remove or disable the PID. Set the valve in a fixed position and wait for the temperature to stabilize. Then, change the setting of the valve and record temperature at regular intervals data until the temperature is stable again to a new value. Use these data to get the initial values of PID using the equations provided by the tuning method you choose.

• Display in real time with a delayed recording LV6.1

  Hi, I need help with LabView 6.1

  I have a hardware module FieldPoint where I read 8 channels for thermocouple. I want to display the value of the thermocouples in real time (or as close as I can manage) all saving the values in a CSV file at discrete time intervals (every 10 seconds). I am able to display the values in real-time, but the recorder real-time records, produce a lot too much data. I'm able to delay the recording interval, but in bulk then display in real time!

  The following example shows a method I've tried. The delay time in the loop of logging seems to delay the entire program. I also tried to use the loop of the logging of a sequence (using a simple delay of 'Wait') structure and a structure of matter (with a counter and only do the loop of logging real when the counter gets to 1). I tried to configure synchronous display without success.

  I'm having no luck and wonder if someone could point me in the right direction?

  Ah, the benefits of time.

  I think that I managed to create a solution for me using a different tact. Instead of using individual meters of delay, I used a "trigger time" approach as demonstrated in this thread;

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=286988&query.ID=6280650#M286988

  Currently, it is limited because it will allow only a delay of 59 seconds between the readings, but this should be relatively easy to solve. The solution works continuously update the display with a slight delay to help cope aging computers, and then the button "Log Data" is selected writing worksheet function is called second pushed together as selected. Quite a simple and elegant solution I think.

  Hi jomabe,

  Thanks for posting of answers.microsoft.com with respect to this application.

  According to the information provided, it can be either parameter must be changed or the option of power setting could be revised in order to help you with this problem.

  For a change of setting screen saver, click on empty place on the desktop and select PERSONALIZE / screen saver - check if the waiting period is set for a time relevant to your operation or if it needs to be revised.  In addition, if the Logon Screen summary view is checked, it will ask login during the resumption of the activation of the screen saver.

  Another area that may be the result of what is living could be in the power Plan options.  To check if the power management options contribute to the problem, follow these steps to customize a diet plan to check whether components that can be going to sleep can be adjusted to your needs.

  How to customize a diet plan

  To customize a diet plan, follow these steps:

  1. Click Start
