Restarting a elapsed time function in a for loop
Hello,
I am having an issue while using an elasped time function inside of a while loop (I wire the Time has elapsed? boolean to the stop function of the while loop), that is consequently inside of a for loop. The elapsed time function works correctly on its own in a while loop, but when added to a for loop will not reset for each iteration of the for loop. I can post an example if it is needed, but has anyone run into this problem before? I have tried wiring all the reset boolean's but I cannot get the timer to reset untill the for loop has finished.
Any suggestions on how to achieve this another way are welcome.
Thanks,
Andrew
I found the issue, I was using 2 timers inside of the for loop on the assumption that they are completely independant of one another....they are not. if time has elapsed on one timer then it uses that time to start off the next timer, kind of a wierd behaviour but I guess I am not really using the timer in a normal manner.

How to use elapsed time function with state machine in Lab VIEW
Hello
I've been trying to use state machine with elapsed time function in order to sequentially start and stop my code. The arrangement is to start the code for 1 minute then stop for 5 minutes. I've attached the code, the problem is when I place the elapsed time function out of the while loop it doesn't work, on the other hand when I place it inside the loop it does work but it doesn't give the true signal to move to the next state.
Could you please have a look to my code and help me to solve this issue.
Regards
Rajab

Thanks apok for your help
even with pressing start it keeps running on wait case
could you please explain the code for me, the use of Boolean crossing, increment , and equal functions
Best Regards

OK..I modded the example to stop after 2 cycles. Also recommend taking the free online LabVIEW tutorials.
run vi. case statement goes to "initialize", shift registers are initialized to their constants. goto "wait"
"start"= false, stay in current state. If true, transition to "1 min" case
reset elapsed timer with True from shift register(counter starts at zero)."time has elapsed"=false, stay in current state(1 min). If true, goto "5min" case
reset elapsed timer with True from shift register of previous case(counter starts at zero)."time has elapsed"=false, stay in current state(5 min). If true, goto "1min" case. Also, bool crossing is looking for "true-false" from "5 min" compare function to add cycle count.
Once cycle count reaches 2, stop while loop....

Bonjour,
Je vous expliques en quelques lignes mon problème.
Je possède un compactRIO 9024, qui fera des mesure de résistance avec une carte NI 9219.
Je dois alimenter la bobine d'un relais (branchéé sur un contact), et démarrer un compteur à ce moment
Ensuite, le compactRIO devra mesurer la valeur de la résistance du contact du relais et stopper le compteur lorsque ce contact sera fermé (résistance nule ou proche de 0)
Ce test doit permettre de calculer le temps que le relais met entre le moment où sa bobine est alimenté ou le moment où le contact est réellement fermé.
J'ai pensé à utiliser la fonction Elapsed Timer function, mais je n'arrive pas à la faire fonctionner.
Quelqu'un aurait il un exemple ou une autre méthode?
MerciBonjour,
Je me suis amusé à vous faire une FGV timer qui renvoie des milliseconde (avec LV2010 et 2009 au cas ou):
Que vous pouvez mettre sur votre partie RT, en gros cet FGV à 4 etat:
Init pour reinitialiser le timer.
Start pour lancer le timer
Stop pour stoper le timer
Get pour avoir la valeur du timer.
J'espere que cela vous rendra service.
Cordialement.

Help with quit function and elapsed time function.
I have this annoying assignment game here and I am almost finished with it. I got two problems, the first is that the quit function partly works it quits from the game but it is giving me a "Guess is to high" message. I've tried so many things but nothing seems to work.
The other problem is that the elapsed time " *(long f = System.currentTimeMillis()/1000;)* " starts to count before you actually write something for example if you run the program without writing something for 5 minutes, the highscore list will show your time you finished the game + these 5 minutes.
If somebody could give me a hint or could explain to me how I could fix these problems I would be very thankful.

Hi Again want to confirm with you Oracle gurus ...
Does following plsql code really takes time in mins

-> TableB has some thing which i wnat to append in text_data column..
-> Trying to minimize elapse time..

Check Scan for NI435X and elapsed time doesn't run in loop
Dear all Labview Experts
i have 2 questions
(1) i written program with Check Scan for NI435X (input to no of scan to NI 435X read ) and one with only NI435X read( to read in voltage) with constant input to no of scan,
the data i obtained is attached in 2 doucments; With Check Scan and without check scan ( the left column is temperature read in ( a formula is used to convert volt to temperature, right column is time)
strangely the program with check scan shows values in negative ==> Voltage read in is 0, strange, why is this so??? and why is there a diff?? Hope u understand my question
(2) For elapsed time, i want to find the total elapsed time for the whole program as well as individual cases, there is no "running" elapsed time or individual running time,
what happen is that when the each case end, the time will jump (e.g. from 0 at start, it will change to 5.35 at end of case) , is there any where to make the time run, i need it because some case required
c
ondition such as case will move to next after 5 seconds, but if above case happen, the vi will only stop if i put >= 5 rather than just place = 5
hope u understand,
does it help if i placed the condition as another loop , will it mean the same things
Attach are vi and some doucments, however as my vi contains PID tool kit as will as ni435x ni DC power which cannot be opened if you do
not have these kits.......however mayb u can help to look at the portion of timing as this is the main problem i faced now.........
Hope it is not too confusing for you to understand me...........
i can only attach max 3, the next post i will attach 2 vis...........

Picture of check scan and without.rtf 15 KB

Attached are 3 VIs
1.the first vi is the one with the check scan
2. the next two vi the only diff is the placement of the where i put the elapsed time and time of each case.........(without check scan)--the first
one is within the big loop, the other outside big loop -- the purpose i did this is because when i run the vi with the timing in the big loop, the timing does not run continuously but "skip". for e.g. Denature time: from 0 . it jump to 5.15s without showing the running.............
i will attached another 2 vi s in my next attachment

Functions in a For Loop defining objects from an Array. . .Why Won't This Work?!
I'm trying to put these functions into a Loop to conserve
space. Why won't this work?
.Yeah, sly one is right. You can not have the "i" inside the
onRollOver function, what you have to do is: As the movieClip class
is dynamic you can create a property of the movieClip which stores
the value if the "i". And then, inside the onRollOver function, you
have to make reference to that property.
for (i=0; i<2; i++) {
this.regArray
.iterator = i;
this.regArray.onRollOver = function () {
showRegion(regArray[this.iterator]);
this.regArray
.onRollOut = function () {
hideRegion(regArray[this.iterator]); -
How can i reset elapsed time VI
I am using the elapsed time express VI along with an "in range" comparison VI as the exit control for a torque test. If the voltage signal from the torque transducer is within the specified range for the target time, the loop exits. If the voltage signal is out of range, the elapsed time resets to zero.
My problem arises when i exit the loop prematurely due to excessive torque. Like if torque reaches the transducer limit, I want to exit the loop to prevent damage. When i exit the loop like this, the elapsed time VI continues counting even though the loop has been stopped. The next time the program enters the state, it exits immediately (because torque is initially zero, and the timer has passed the set time). After that iteration the program behaves as i expect it to, because the VI has reinitialized I assume. I have been stuck on this problem for several days, and I'm going to start breaking company computers if i can't fix it.
So my question(s)... is there a way to reset the elapsed time VI upon entering the while loop? is there a way to reset the VI from the 'torque limit' state immediately following the exit? I also use a 'resume test' button so the user can restart the test after checking the unit,hardware,etc. can i wire something to that button press to restart the elapsed time VI?
My 7.1 vi is attached, the elapsed time problem being in the 'exercise' state. immediately following an 'exercise' torque limit, it goes to the 'torque limit' state, which i thought could be used to reinitialize the elapsed time somehow.
Thanks,
Evan

DB6483 Test.vi 2932 KBI have a similar problem ,
I use a elapsed tiem function ,with a target of 1s time.
i want to caluclate mean of samples in this 1 second
but what i see i get 8-9 mean values in 1 second
i also wired my i of while loop to auto reset with case structure,but even then i see so many average sample values in a second
to be more precise i want data like this:
when my DAQ board gives some 1000 samples per second. i need mean of these 1000 samples,but not all 1000 sanmples.
for this i included a elapsed time vi with taget of 1s. (didnt forget to reset after 1s).
but what i see is it gives values like this
12:12:01 d1 d2 d3
12:12:01 d1 d2 d3
but i expect like
12:12:01 d1 d2 d3
12:12:02 d1:d2:d3
did i go any where wrong in my Vi.
how can get out of it! -
hi....
first of all ..sorry if the subject title didn't match with my problem. I have no idea what is the suitable title should i put there.
anyway my question is..how should i do to set every one hour i can run a subvi?for example i have a subvi that use to send a msg to the gsm card to delete all the read msg inside the simcard. so means that I want to delete all the messages every one hour. if i have delete the msg i will stop the subvi and wait for next hour to delete the message.
anyone can help?..pls..hope that's all clear..
thanks..Or you could use the Elapsed Time function wired to a case statement with you subVI inside that.

Multiple indicator from elapsed time
Hello all,
I need help in simplifying my block diagram. In my semII)timing.vi, i include multiple LED indicators that would light up on specific time. I've also included a time display to indicate the elapsed time. I've also included and On/Off light tht would turn red when the test time(6mins) has ended.
But recenlty, i came across the Elapsed Time function as seen in the sem11)elapsed time.vi. I'm trying to incorporate that function, but it only allows one set timed.
Could anyone suggest how i could include multiple controls, so multiple LEDs can light up at different times (at every mins)
regards,
beplusso.

semII) Timing.vi 45 KB
semII) elapsed time.vi 38 KBHere's something that should at least give you the general idea. I don't know what version of LabVIEW you have, but these are in 8.2.
I put the comparisons for your LED indicators into one vi, and the code that calculates the (m) and (cm) into another. In a simple program like this, they are not really necessary, but if your code were to grow (which it easily can) it might make things cleaner later on.
Finally, you should always use labels for all of your controls and indicators. You can simply hide them if you don't want to see them on the front panel (right-click on the front panel item and select Visible Items - Label), and it makes wiring and debugging much easier.
Good luck!

Hi,
I am doing this motion sensor project. i have gotten it to work like when it senses a motion it will light up the boolean led. so now i am suppose to add a some sort of timer which some has recommended me elapsed time, i tried figuring out but i dont know how to wire it to my program. My task is to set a timer, so that when 10 mins has passed and no motion is detected it will trigger a logic 1 ( Digital Input ) to another program. But right now im focusing on this program as i need to integrate both. So how do i wire it to make it like how i had described. And lastly i need a reset button so that after it input a logic 1 ( which will trigger a alarm - another program ) it can be reset and countdown 10 mins again. ThankyouFirst, you should continue in your original thread.
Next, take the LabVIEW tutorials.

Then, read the help file for the Elapsed Time function.
Finally, set up a simple VI where you can experiment with how that function works.

Direct Path Read waits are not showing in Elapsed time
Hi,
I'm having a question regarding interpretation of a SQL trace file. I'm on Oracle 11.2.0.1 HP/UX 64 bit.
Following is only the overall result of the trace (it is quite big).
My question is about the Direct Path Read waits which are totallizing 268s of wait but are not showing in the fetch elapsed time (49.58s) and are not showing anywhere in the trace except in the overall result.
I do not understand why it is not part of the Elapsed time...
For info, the trace is for the specific session that was performing all the required queries to display an online report. The database is accessed by the Java application using Hybernate.
The trace was obtained by the following SQL:
exec sys.dbms_monitor.serv_mod_act_trace_enable(service_name=>'SYS$USERS',waits=>true,binds=>true);Then I query the sessions to find the one created by the application.

Closing this thread even if it's not answered...Sorry, I don't have time to test this myself now, but you shouldn't mark this thread as answered if it is not, because other people might find it and think they find an answer if they have a similar question.
I suggest you try the following to narrow down things:
1. Open the RAW trace file and check the cursor numbers of the "direct path reads" - check if you can find any references for those cursor numbers manually. The cursor numbers are those numbers behind the WAIT #<xx>, and you can check if you find any other entry unequal to WAIT #<xx> with the same #<xx>, for example EXEC #<xx> or FETCH #<xx>
A short primer on how to interpret the raw trace file can also be found in MOS document 39817.1
2. Run the RAW trace file through alternative free trace file analyzers like SQLDeveloper (yes it can process raw trace files), OraSRP or Christian Antognini's TVD$XTAT. If you have My Oracle Support access you can also try Oracle's own extended Trace Analyzer (TRCA / TRCANLZR). See MOS Note 224270.1
Check if these tools tell you more about your specific wait event and oddities with the trace file in general.

Randolf

How to define function within for loop pls help?????
Hi this is the problem i have a class, and within that class there is an actionPerformed function, in this class i also create an instance of another class, this other class also contains an actionPerformed function, which wis executed if a jButton has been pressed, when I try to place this actionPerfromed function within a for loop of a function i get an error saying illegal start of experssion, and that the class should be defined abstract as it does not define actionPerformed, when i take it out of the for loop it compliles fine, i need the function to be placed within the for loop because it needs to know the variable of the for loop, is there anyway around this? Thanks, below is the code:
public class DisplayTransitions extends JFrame implements ActionListener
public void add()
for(int i = 0; i < char2.size(); i ++)
mPanel.add(tim[i] = new JButton("Time"));
tim.addActionListener(this);
public void actionPerformed(ActionEvent ae)
if (ae.getSource() == tim[i])
timeIncr();This is your for loop using an anonymous inner class for the listener:
for (int i = 0; i < char2.size(); i++) {
mPanel.add(tim[i] = new JButton("Time"));
tim.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if (ae.getSource() == tim[i]) {
timeIncr();
Learn more about anonymous inner classes from a good Java book or the Java tutorial (try http://java.sun.com/docs/books/tutorial/java/javaOO/QandE/nested-answers.html). -
Date Utility - calc age, elapsed time...
I need to calculate elapsed time between 2 dates, for example calc age based on DOB and Today. There must be a utility out there somewhere (free!). I'm sure I'm not the first one with this requirement.
try this
import java.util.*;
public class DateSub {
public static void main(String [] args) {
Calendar cal = Calendar.getInstance();
cal.set (1970,0,1);
long age = cal.getTime().getTime();
age = System.currentTimeMillis() - age;
System.out.println ("age = " + age + " milliseconds" );
age /= 1000;
System.out.println ("age = " + age + " seconds" );
age /= (3600*24);
System.out.println ("age = " + age + " days" );
long years = age/(365);
long days = age % 365;
System.out.println ("age = " + years + " years " + days + " days");
}
