Pause action .vi while a specific sequence is running
I have a test fixture with two sockets. In teststand we have a prerun.vi in the setup tab that preps some reference equipment. What I need to do is pause the execeution of that vi only when a specific sequence in the main sequence is running. Is there a way I can monitor the execution status through teststand? For example socket 1 is running a uut and someone starts a uut in socket 2 while sequenceX is running. I want the prerun.vi to halt execution until SequenceX is done running.
Use the syncronization step types. A notifier step would probably work good.

Continue execute program while a specific sequence only should be executed every second
Hi everyone
How can I make a sequence executing every 1s while continue executing other code in the meanwhile.
e.g.: A ligth should blink with a frequency of 1s. This should be done independently from other code running the same time.
I really was trying it out a plenty of time unsuccessfully. "wait" does not work, "wait until" not either nor does event struct or anything else work out for that... well I thought "simple" issue.
Could anyone give me a hint or even a example code? Please note that in my issue I don't only want to execute only a blinking LED. Lets say I want to receive updates from a board via rs232, but only every 10 seconds. Meanwhile I want to execute other code.
Thanks for help!!
Background inforamtion:
Since 2 month I am programming a GUI with LabView that gives me the ability to control instruments via the rs232 interface. Until now I figured out a lot of LabView by my self but here I got stuck :-/
Solved!

"wait(ms)" or "wait until..." should never be used for application timing, they are used for loop iteration and synchronize loop processes. Use the other timing functions like elapsed timer or tick count....
CLD....
b. Timing functions
1. Use the Wait function to control the loop execution rate and allow the processor to respond to external events and system tasks
2. Use the Wait Until Next ms Multiple function to control the loop execution rate and to synchronize multiple loops
3. Avoid using any of the Wait functions to time a software operation
Well, I was just focusing on the blinky, and didn't figure it to be a time-critical operation (I figured the same thing for the data acq every 10 sec, but this may not fit his requirements). What I do when I just want to make a blinky is to set up a loop which switches the LED between off and on. That way I can change the period, otherwise, I would just use the "blink" property node (1 sec period, IIRC).
But, as you say, in time-critical operations, you do want to use the time functions which do depend on the absolute value of the system clock. In a parallel loop.

Auto pause time machine while other backups run
I backup every hour with time machine
Also every night while in bed backup does multiple backups to other locations
Is there a way to automatically turn off or pause time machine while these other backups take place and then start it when they finish??
I'm using the apple backup application v3.12
I've tried the automator but when I play back the recorded 'watch me do' it never seems to play back quite the same or I get 'the action "watch me do" encountered an error'
Many thanks for your help on thisBasically I am using time machine straight to a 500 gig Time Capsule via Gigabit Ethernet most of the time, sometimes through airport although it is slower, even using 5Ghz on draft n!
Also at night from 2am the following backups run using the backup app
Backup my accounting files to idisk every night only about 100Mb,
Backup my User folder to partition 2 of a 1Tb WD drive connected via USB to my Time Capsule and also to my time capsule every night
Backup my whole hard drive excluding user folder to partition 2 of the 1Tb WD drive on monday early am and to my timecapsule friday am.
Partition 1 is a backup of the time capsule done manually through airport utility
All this means that if a backup drive fails (tc or 1TB wd I've still got all my backup data on the other drive.
Worst case senario I lost both drives and my laptop I would at least have my account's on my I disk.
I think I may get another 1Tb and rotate them taking 1 off site
This may seem ott but I lost my last mac and lost some data due to and old backup drive that was failing. So I don't take chances now!
Thanks for your help on this.
Thanks for you help on this much appriciated -
Error while creating Access Sequence (output)
Hi,
While creating Access sequence (for an output) i.e. Access Sequence - Accesses - Fields (at this point)
I am getting an error (I/O) in the field. The field value is WERKS and not able to go further.
I created a table for output billing and criteria fiels are sales area and plant.
Please guide me in this regard.
Thanks and regards,

I created a condition Table xxx and selected fields (Sales Area, Plant). While creation of access sequences for an (output type) at the Fields level i am able to see all the 4 fields but with the field WERKS it is showing an error.

Infinite loop - "Some actions taken while...offline could not be completed"
I have 4 IMAP accounts (.Mac, Gmail and 2 at SpamArrest). Occasionally, I get in this infuriating state where I keep getting the following error:
"Some actions taken while the account "ClickMarkets-SA" was offline could not be complete online.
Mail has undone actions on some messages so that you can redo the actions while online. Mail has saved other message in mailbox "INBOX.Sent Messages" in "On My Mac" so that you can complete the
actions while online.
Additional information: The connection to the server "mail.spamarrest.com" on port 993 timed out."
The only way I've found to resolve this infinite loop of messages (which subsequently backs up all other mail processing) is to quit mail, then cd to ~/Library/Mail/[email protected]/.OfflineCache and delete everything in there then relaunch mail.
In each cases, I end up with a mailbox folder (Sent or Drafts) in the folder "On My Mac" which has one copy for each attempt at handling the message "online."
I opened up the Connection Doctor and looked at the log details and saw that Mail is opening a socket to spamarrest and starting an APPEND operation on my INBOX.Drafts folder -- I have "store drafts on server" checked. It appears the APPEND operation is hanging and causing a timeout (see transcript below). This happens every 60 seconds. The error that I see after the timeout is:
* BYE [ALERT] Fatal error: INTERNAL ERROR: Keyword hashtable memory corruption.: Input/output error
Who's Fatal error is that?
SpamArrest is trying to tell me the problem is with both of my computers and not their server. (Yes, this is hitting both my MacBook Pro and my iMac). Can anyone shed some more light on this? IMAP should be able to handle multiple computers so I don't see that as a problem. Is my Mail app not following protocol? Is it a filesystem issue (e.g. SpamArrest doesn't like the name of the folder)?
Thanks.

Some actions taken while the account was offline Part 2
Some of us were getting this message with IMAP accounts: "Some actions taken while the account was offline could not be completed." with Leopard. Along with this, an email, usually too large to send, would keep saving itself in the drafts folder. The fix for this was to delete the OfflineCache folder in the IMAP folder. Well, we upgraded to Snow Leopard and now I am having the same thing happen. Except now, I dont get the message and the messages save to Recovered Messages. So I tried the old trick and that folder doesn't exist anymore. What do you guys suggest we do?
Did you solve this? Do you still see it in 10.6.2? I have
had this issue as well and am looking for an answer.

Some actions taken while account was offline in Lion
"Some actions taken while the account ... was offline could not be completed online." I have seen this message mentioned in Leopard and Snow Leopard. I never got it in that. I am getting it since Lion 10.7.4. About accounts that appeared to be online at the time. Moreover, there are messages that were sent, in that they show up in Sent mailbox, and in at least one case today I got a reply back, but here they are in the Recovered mailbox. So were they sent or not? Can I believe my Sent box or not? And what "actions" were "undone ... on some messages"? There is no list of that anywhere that I can see.
Did you solve this? Do you still see it in 10.6.2? I have
had this issue as well and am looking for an answer.

Some actions taken while the account “MobileMe” was offline could not be completed online.
Mail has undone actions on some messages so that you can redo the actions when online. Mail has saved other messages in mailbox “Recovered Messages (MobileMe)” in “On My Mac” so that you can complete the actions when online. -
Pause and restart while loop after defined time
Hello,
What I need is to find a way to run a while loop that is acquiring and analysing a movie, to pause this while loop for a time I specify, and re-run it after that time has passed.
I'm attaching a picture of the relevant parts of my VI. In the case structure of the "true" or "false", the program is checking, online, if the eye (my camera is focusing on the eye) is open above some threshold and for a certain duration of time. When "condition to start" is met, two things happen: one, the case structure changes to "false" and waits for some time; second, the loop of my state machine is triggered. Problem is, because I'm not really pausing my while loop (it's still running even when it's the "false" case), my state machine runs really slowly - for example, I have a part of video acquisition in my state machine, and saving the frames to avi takes forever.
Does anyone have any idea of how I could stop the while loop for x time?
Thanks in advance!

help_pauseWhileLoop.png 112 KBHi,
I'm attaching (hopefully) better pics, if you still can't see let me know and I'll attach the code. About the frame saving and acquistion, I'm already doing that in a separate loop - you can't see my entire code in the pics, but what I have is a state machine that works as a producer loop and then a consumer loop, where video acquisition is happening. Now I'm working on a third loop (the one in the picture), that starts before the others and where I don't even want to save the movies - I just want it to check, online, if the condition is met (e g, the eye is open for a specified time) and if so, start the state machine and stop running, until the state machine has finished running. Then do the same, after waiting a specified time. I know that the problem is that the while loop keeps running after triggering the state machine, because if I remove that part and trigger it manually, the VI runs just fine and really fast. So how can I run, stop and restart the while loop?

Deleting specific sequence numbers
Gurus!
I have a scenario in which , I would like to revoke / delete the disabled java.io.filepermissions on a Specific Oracle9i Schema.
i tried to delete the KEY values from DBA_JAVA_POLICY / USER_JAVA_POLICY
then i came to a point that as these both are Views we cannt delete the data.
So I tried to delete a specific sequence numbers ( 71 to 79) for a GRANTEE# number 31 from the base table that is java$policy$ but still am not able to . the errors SQL command terminated improperly ( somehting like that)
Please help me out with this. as I already upset with this.You are not supposed to mess with the data dictionary, otherwise unexpected results may start to show up.
Granting or revoking privileges must be done with proper commands provided explicilty for that pourpose.

How to load programmatically from CVI the specific sequence file in TestStand 3.1
I am trying to implement TestStand from Windows/CVI 3.1. I need to insert a specific sequence file in TestStand, with all other sequences unloaded. I used TSUI_ApplicationMgrCloseAllSequenceFiles() and TSUI_ApplicationMgrOpenSequenceFile(), but after Username/Password prompt, the TestStand loaded all the old sequences. How to eliminate this?
Hello,
I created a function that calls those two methods. When I made a simple CVI button and in a callback for it, I call my function, it does successfully close all open sequencefiles and then load the one I specified; however, it does not work when I call the function just before the call to RunUserInterface! I am very surprised by this and will be bringing it up with our R&D department. There is a simple work-around. Instead of closing all open sequencefiles at the beginning of the OI, close them at the end instead. I have modified the full-featured OI for you and tagged in the code where I made changes. This should do exactly what you want (you may want to change the code around to make it a little cleaner...I left more in code in than I needed for instructive purposes). Please let me know if you have any questions about this. Take care!

S.Venkata AppajiAppaji,
My guess is the file is corrupt. But first, let's make sure you have SP2 installed. It appears from the version number above that you do not. You can download SP2 at: http://support.microsoft.com/kb/2687457. I also recommend you install the June 2013 cumulative
update. You can get that at: http://support2.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2817385&kbln=en-us.
If after installing the updates you still cannot open the file, go to the MVP website at, http://project.mvps.org/faqs.htm and take a look at FAQ 43. Use method 4.
Hope this helps.

New Login while Sequence is running
Hello,
i´m running a Labview-Operator-Interface which is executing a teststand-sequence.
This sequence is running parallel an executes from time to time a new seqeunce in "a new execution".
On the operator-interface are serveral functions which i want to make only executable for some users.
The problem ist, that after the parallel-sequence is running i have no more acces to the Login-Button ( it becomes greyed out).
So my question is: How can i execute a login with User/Password while a seqeunce is running?I am using TS 3.5 and LV 8.2.1.
When i execute the default (untouched, unchanged) Operator-Interface from NI located in
C:\Programme\National Instruments\TestStand 3.5\OperatorInterfaces\NI\Simple\LabVIEW\Testexec.exe
then i have the problem also.
What i do:
- Run this Operator-Interface exe-file
- Click on "Open Sequence File" and select the sequence what i posted before.
- Click on "Test UUT"
- The Sequence begins to run and displays the first popup
But now the Login/Logout-Button is greyed and disabled.
This is what my problem is also in my customized UI.
What you say is, that your Login-Button is still normal and clickable with TS 4.0 ?
Attached a screenshot of the UI and the first-popup + the greyed Login-Button

How can I run a SubVi in background when a sequence is running in the main VI
What I want to do is this
When I push a button on the main VI, a SubVI (#1) must run and take data.
At the same time, a sequence, in which there are other subVIs must run.
My problem is that the subVI #1 does not run when I push the button. The sequence is running well. How can I run both the sequence and the subVI at the simultaneously?
Solved!
Go to Solution.Hey Hugo,
Sounds like you'll just want to do some parallel loops. I'll attach a screenshot of a VI that has a sequence where the counter goes up to 3, then restarts, each time it reads the iteration count from the subVI above. (The subVI is just a while loop with the iteration count attached to the global)
Each iteration of the sequence shows an increased count from the subVI via a global variable.
Is this what you are looking for?
Keep in mind that I just threw this together to show functionality, its got a lot of rough edges to it.

Why the execution time increases with a while loop, but not with "Run continuously" ?
Hi all,
I have a serious time problem that I don't know how to solve because I don't know exactly where it comes from.
I command two RF switches via a DAQ card (NI USB-6008). Only one position at the same time can be selected on each switch. Basically, the VI created for this functionnality (by a co-worker) resets all the DAQ outputs, and then activates the desired ones. It has three inputs, two simp0le string controls, and an array of cluster, which contains the list of all the outputs and some informations to know what is connected (specific to my application).
I use this VI in a complex application, and I get some problems with the execution time, which increased each time I callled the VI, so I made a test VI (TimeTesting.vi) to figure out where the problem came from. In this special VI I record the execution time in a csv file to analyse then with excel.
After several tests, I found that if I run this test VI with the while loop, the execution time increases at each cycle, but if I remove the while loop and use the "Run continuously" funtionnality, the execution time remains the same. In my top level application I have while loops and events, and so the execution time increases too.
Could someone explain me why the execution time increases, and how can I avoid that? I attached my test VI and the necessary subVIs, as well as a picture of a graph which shows the execution time with a while loop and with the "run continuously".
Thanks a lot for your help!

Thank you very much for your help! I added the "Clear task" vi and now it works properly.
If you are still using the RUn Continuously you should stop. That is meant strictly for debugging. In fact, I can't even tell you the last time I ever used it. If you want your code to repeat you should use loops and control the behavior of the code.
