Simple trigger and alarm Question

Thanks in advance for your help.

My situation:

I have the measurement computing USB DAQ with Labview 8.6 1208FS (ULx using). Am I voltage to a load cell measurement and the need to put in place a range of alarm

  • Load cell by smallload and ramps then begins up to about 15 lbs
  • I would like a continuous display of the data on the chart
  • I need to know if the load went down 15.1 14.9 or overwhelmed below (via two separate front led remains lit if the charge was never out of reach)

My understanding is that I need some kind of trigger to make the alarm go off like the ramps of load cell up to past 14.9 lbs.

Phil,

Given that in a single iteration is reading your data acquisition (read data) an array of values or a waveform, all arithmatic operation will be done on all these values and thus the output of a table or values. In your case you are looking for the trigger condition so I've been chnge the data in table 1 d (easier to treat) and look at the max value and then compare with the threshold so the value out would be an element and not the table of elements.

Thank you odessy27,

I want to be constantly looking at my input voltage and switch to a mode 'on', he spent the trigger threshold.

  • Always begin near 0v and ramp up about 7v comments
  • Once it exceeds a certain trigger level, say 6.95v, I want mainly to 'start' of the program
  • At this point, the VI needed permanently watch entry and turns on an LED if the voltage is less than 6.9v or superior 7.1v.

The conditions you mentioned can be achieved with the help of another structure within the existing case. Try it and let me know if you find it difficult to implement.

    Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.

    You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.

  • Satellite L750 charging and the question of the random stop

    Hi all

    Recently I had problems with my laptop Satellite load.

    The laptop is running Win7 64 bit and is a Satellite L750 PSK2YA - 0LN028

    Now the problem is not that his load not but that he chooses to charge and no fees when he wants to. With the laptop plugged into current alternative to a real charger Toshiba (3.96 tested A 19.48V) the laptop charge for a minute or so normally with the animated icon (moving) in the set by saying "plugged in, load. Then all of a sudden the animation stops in the status bar, but it still says "plugged in, charging" 2 lights on the front of the laptop flashes orange simultaniusly (power and battery NOT AC led) and the computer will decide to drain itself of the battery, then stop without warning (with connected AC).

    This will happen under simple highload AND webbrowsing. My dough said Toshiba PC health integrated program is 'good' and that CPU Temp is not more 70% and the fan works as it should. When I remove and reconnect the AC adapter it will stop blinking and start to load for a minute and then start all over again.

    I tried to remove and reinstall the battery Module controller via Device Manager and Reset BIOS by disconnecting all power and hold for 30 seconds, these two methods do not fix my problem.

    The computer still works on AC if the battery is removed and the only devices I plugged in a USB mouse that is NOT plugged into the slot of the USB3.

    Any help would be greatly appreciated or if someone knows what that flashing lights twin mean on a table of errors, or something (because I can't find the online error codes). It's my first laptop and I bought this one thinking that I could do most of my stuff a desk would be, but it's just been a nightmare...

    Thanks in advance, if you need more info let me know.

    I recommend you test another, a good pile of work.
    Not quite sure if he s really make a battery but in all cases of problems of load, the battery should be checked as well as another adapter.

  • How to trigger and outputs analog and digital Outout tasks begins on a counter to start?

    Hello

    I'm trying to synchronize the start of a task outputs analog, a task of digital output and a task of counter. I want to start the counter to serve the master trigger and analog and digital tasks to synchronize his departure.

    I guess I need something like:

    analogOutputTask.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger ("?", DigitalEdgeStartTriggerEdge.Rising);

    digitalOutputTask.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger ("?", DigitalEdgeStartTriggerEdge.Rising);

    analogOutputTask.Start (); Slave 1

    digitalOutputTask.Start (); slave 2

    () counterTask.Start; n / / master

    Where? is a string specifying a command source for the beginning of the task of the meter. However, I can't find what this string. Any suggestions?

    Thank you!

  • WinXPsysytem: The upgrade and have questions

    Have a dell e521 that I train and some questions.  Have already updated to 3 GB of memory on x 86 operating system.  Bios version active what 1.1.6 4/7/2007.  Have checked Dells site and they offer a version of bios 1.1.11 released on 04/09/2007.  Having checked their previous versions and mine is not yet in there.  Don't know if I should go with the 1.1.11 version or stick with what is on mine, any suggestions?  Also, I put in a 500 GB seagate HDD.  Have a 80 GB drive there now which is pretty maxed out.  Playing with the idea to put xp pro on the 80 GB and using the programs and storage 500 GB.  I would like to know if it's a good idea or not!  Could use pointers and how much others who have more experience I have of course on my best options for installation.  for performance and features.  Thank you in advance, Ron.

    It's sad to say, you should probably have spent your money on a new computer rather than on the RAM and a new hard drive.  Windows XP (you posted in a forum of Windows XP, that's what I assume you have) will be supported is no longer starting in April 2014. This means no more security updates and therefore increases the vulnerability to malware.

    That said, your system now-updated can probably support Windows 7. You must run the Windows 7 Upgrade Advisor to check the remaining material.

    As you say, Dell does not list the intervening versions of BIOS with 1.1.4, 1.1.10, so unless someone at Dell or in the Dell forums can tell you what "improvements" in your version or with your version 1.1.10, you have no way of determining that. Based on omissions, I think there were only minor changes in these versions.

    Normally, I would leave the BIOS alone.  Note, however, that Dell "recommends" 1.1.10 be installed because
    The update contains improvements or changes that will keep your system current and compatible with other system modules (firmware, BIOS, drivers and software) software.
    If you want to stick with XP, I would leave the BIOS alone. If you want to install Windows 7 (assuming that there are Windows 7 drivers for all your hardware), I would Setup 1.1.11.  Be sure to read and follow instructions carefully.

    BTW, it's a little surprising that you only have a 80 GB drive.  CNET review of the Dimension E521 said he came with a 320 GB drive.

  • Lost Pack of ringtones and alarms Experia

    Once upon a time, my Z3 was a strong pack with a selection of ringtones and alarms to the choice. Now, it is no more and I don't know how to get it back.

    Hello and welcome to the community!

    If you do not see the ringtones pre-installed, it might be that you have selected the wrong app to choose the ringtone with.

    Go to settings--> Apps--> [menu]-> preferences app Reset and then go to settings-> Sound & notification-> phone ringtone and select the "sound selector" app and see if that helps.

  • Drag and drop question - Desktop and USB

    Hello!!

    I have an Asus laptop that I bought in September with Windows 8 is installed. I saw drag and drop questions on desktop lately, and I'll provide you with a full run down of what past:

    1. this particular case, I wanted to save my mobile by copying and pasting all the files from my phone to a USB (USB Kingston).

    2. I selected all files, right click to copy, open the folder that I made in the USB for my phone content and do a right-click Paste.

    3. nothing's happened, Explorer seems to have frozen, so I opened the Task Manager and press end task, all closed and restarted my laptop.

    4. I have excluded that my phone was the issue. I was able to create a folder on my desktop and copy and paste all of the content of my phone in the folder on my desktop.

    5. I tried to copy and paste / drag and drop an image from my office to the flash drive. Explorer Windows freezes on the rise again.

    6. I tried another flash drive. Explorer Windows froze again.

    Apparently I'm unable to copy files ON a USB key, which makes the backup and backup of things a headache because Windows Explorer stops working every time.

    I am the only user of this laptop, and I don't know what is happening or what to do. Any help would be appreciated. Windows 8.1 upgrade would solve this problem?

    Hi Karthik,

    1. There is no error message.

    2. I tried earlier drag - move my documents to my flash drive and it works perfectly.

    I just tried again to drag and drop from my office to my flash drive and for some reason, it works again.

    I don't think that was with my flash drives, but with Windows Explorer itself. Nevertheless, it seems to have fixed itself somehow. Thank you very much for your help!

    I went in lightroom and can't find my photos. I lost the link before and did the right click to find and they have been found, but it's different.

    I bought an external hard drive and copied some elements but did not cut their.  I did a back up on my external hard drive, but even once did not move them. I did the simple troubleshooting and it doesn't work.  I'm trying to find the original by right clicking the? on the folder LR and once I find the file it tells me that Lightroom has this file already in the catalog - and I want to merge. I tried one and it disappeared or moved. Help!

    Use the file Explorer to see if the images are still in their original location. I suspect that move instead of copy them. This can happen if you drag you the.

    I found that it is best to use either right click on a file or folder name and select copy then right click on the drive-destination folder and select Paste or use keyboard shortcuts to copy and paste folder and files from one disk to another. The keyboard shortcuts are the CTRL + key C to copy and Ctrl + V to paste in the selected destination folder-drive.
