Timing of a State Machine in the States

Hi LabView community.

I'm running a state machine (attached) in which I want to measure the duration that the VI is running in several States. The VI is used to take spectra of power of various samples. My scheduled execution goes like this: the user selects on the front panel, how many times they would like to see the data taken. After pressing start on the front panel, a timer starts. When the machine is in State of 'Waiting', I would like to have the VI wait the amount of time the user has selected the amount of time that has elapsed since the user pressed start. So, for example, if the user wanted a spectrum taken every 15 minutes and the time since the departure was 13 minutes, I would like the program to wait for 2 minutes, then repeat.

If someone could help me with this, it would be much appreciated!

Thank you in advance.

You just need to save in a shift register either time has begun the activity.  Or the sum of the amount of time that has already elapsed.

PS: You used a large number of local variables and none of your terminals.  Good number of these local variables should also be so shift registers.

  • Problem updating my state machine, using the emg signal

    Hello

    I have problems with my code. My entry is an EMG signal that I gather from three different electrodes using usb 6008. In the program, I divide the signals and display them in a chart that is unique. What I want now is to read the signal, and if a signal passes a threshold I want an LED lights. This must remain lit until there is another signal that passes the threshold.

    To put it simply: "large enough signal--> lamp on--> stay informed--> enough large signal--> lamp--> stay off the coast and then start again."

    I tried a few different approaches, but I decided using a state machine. Now, the problem is that when the signal to enter the state machine the program crashes. I think it's because the table that I use to convert the signals does not update when I get my state machine, so the signal stops to come. But how to get around this problem? It is even possible to code what I want?

    I have attached the code. All the tips are welcome, I have been struggling with this for some time now.

    Thank you

    The problem is internal while the loop is run until the stop condition is true, but he never does a new Boolean entry. So that it remains for always in the same State. Remove the inner loop and put the shift register on the outer loop instead.

    You must also use a daqmx configures the element, and then set the properties of daq. The read.vi can be set to read a number of samples of each iteration.

    Also: you can expand the table to index for several items of output. If you want that element number 0, 1, and 2, you have yet to wire the index entries

  • I can't create a new virtual machine, for the error "invalid state" of vmware

    Hi, I have an esx server with some production virtual machines vmware;

    Yestarday I made a new VM, suse linux, froma cdrom; but the file system broke down, it has been altered, I don't know why,

    and I had to cancel the machine using the "remove disc";

    After that I could read "a system general error occurred" and when I click on create a new virtual machine (ctrl + n), I can't because the answer is "invalid state".

    When I click on each virtual machine in 'events', I do not see the logs, I see this error "system general error occurred.

    can someone help me? , should I restart the service mgmt-vmware?  (init.d) on the host server?

    Thanks in advance, best regards

    If you use Virtual Center, rebbot VC server and try again. If this does not work, you may have to restart the ESX host.

  • Shared behavior of the virtual machine on the host system shutdown

    Shared behavior of the virtual machine on the host system shutdown

    Greetings,

    I installed WIn7 - 64 bit host system, WS8 and there seems to be a very nice and high quality configuration. I am very happy.

    There is a shared VM and it's a Setup 64-bit Ubuntu 10.04 Server functioning as a base configuration LAMP for some basic web applications, etc..

    I was unable to find the settings to control the behavior of the VM shared with the system that hosts stop. When I stop the host system, I believe that the common VM is off tension or stop gracefully, I don't know who. What I like best is for the shared VM will not apply instead. The reason is that starting the virtual machine is a bit complicated and requires manual intervention. Whereas, if it is stopped since a State suspended without manual intervention is necessary.

    I found that if there is a loss of power, I can hibernate the host system in time before my battery runs out. Resuming the host hibernate system works correctly and the VM shared within WS8 is back to its previous functional State.

    It would be nice and helpful being able to stop or restart the host system and know that the shared virtual machine has been automatically suspended. So now I have to log on to the user account from the host system and open WS8 and manually suspend the virtual machine before you stop or restart the host system.

    Is there a way to have the shared VM automatically suspended when the host system is stop?

    Thank you for your time and attention.

    You can configure the stop action by editing the following file:

    %ProgramData%\VMware\hostd\vmAutoStart.XML

    If you want to configure the action stop for all virtual machines, find the section of under the section. Change it on hold

    If you want to change the action stop for only this one machine virtual, you must first configure this shared VM to be started automatically (in WS, right-click on the item 'VMs shared' in the library, select "manage computers virtual auto-start '). After doing this, manually change the vmAutoStart.xml. Find the entry for the virtual machine in the section (if you have more than one computer configured to autostart virtual, it will take some more digging to understand what VM to change). Change the entry for this virtual machine to hang.

    Save the file. Reboot the host (not auto-start power actions are only made when the host is restarted). Now when stop you the host, WS should suspend the VM (s)

    As always, manually edit the configuration files is not considered supported its use. Save the file before you edit. Adjust at your own risk.

  • Machine on the network share, snapshot at the opening?

    Hello

    I'm new on this, so apologies if I receive the wrong terminology.

    I need to put some infrastructure in place to a Profiler configuration for applications in Citrix flow (although this info is probably not important to do this).

    What I need is the following.

    User turns on the workstation, and then tries to start a machine 2008R2 on a network share. A snapshot is then created, and the user is working on this snapshot. When you are finished, the user stops the machine and the snapshot is destroyed, leaving a pristine environment for the next user.

    Is this possible? Is it possible to do it with a minimal amount of information provided by the user (scripts can help?).

    Thanks in advance.

    install the virtual machine until you get the required state.
    then setall VMDK tononpersistent

    This creates a snapshot too which is automatically deleted when the virtual machine stops - not necessary at all to script

  • How to disable auto-start for the virtual machine at the start of merger?

    Hi all

    I use Fusion 2.0.4 to run different OSs and have 4 different virtual machines that are installed. But whenever I start the merger, regardless of the previous state when I stopped him, he starts a specific virtual machine. How to avoid this? I want to start just merge and then choose which machine to start.

    TIA.

    Hello

    Welcome to the VMware Forums!

    In the virtual machine library, there is a star in the list of your virtual machines that you can click and she acts as a toggle to start the virtual machine on the opening of Fusion.

    It is somewhat a weird UI design choice, don't know me either until someone reminded last week.

  • is it possible to access the virtual machine when the network is down...

    Hello. He... IAM wondering is it possible that we can access the virtual machine when the network is down... (Because of power outages or when the fluctuations...) ................?

    Is it possible that I can configure my Virtual Machine...?

    Thank you and best regards...

    Indianmale...

    Hello

    Not really...

    For an environment hosted... If you can access the console of the host, you can always access the console of the virtual machine regardless of the State of the network outside of the console. VMware Workstation, Fusion and server all fall into this category.

    For ESXi/ESX... you need a host outside to access the console of the virtual machine. ESX and ESXi not displayed graphics or VMs of their consoles and management devices. So, you need an external machine that can run the vSphere Client or access to the virtual machine via RDP, VNC according to Guest OS involved or SSH.

  • What does Time Machine to the top of the address book?

    I use OS X El Capitan (10.11.5) and AddressBook application.

    I created a bunch of groups in the address book and must have one accidentally deleted because he disappeared. I use Time Machine and it seems to be compatible with the address book, so I thought I could just go back to an older version, but I can't seem to make it work.

    If I enter Time Machine from the address book application, I see the old backups to return indefinitely. I have chosen one a week ago and restored, but I don't see the old group. In fact, there are always new groups that I just created today.

    So I did not understand what actually have backed up by Time Machine. Is this just backup contact records, but not groups?

    When I restore, it restores the entire database or just a folder that I'm looking?

    Thanks in advance for any suggestion or advice!

    1. I have a 512 GB SSD HDD and I bought a new external drive 2 TB of HARD drive, how do Mach I use for backup of my internal drive with time machine on the external hard drive?
    2. is it possible to like 500 GB of external drive (2 TB) to use as a second partition for some time and after a few weeks to remove it and use the unallocated space and add to the partition of time-Machine to complete it to 2 TB without deleting anything the backup?

    Thank you very much
    Amit

    1. at least 1 GB.

    2. Yes. Use disk utility to partition the drive, and then make sure that the 500 GB partition is below 1.5 CT one in the list.

  • Time machine removed the external drive without warning

    Hello

    I had an external hard drive with a time Machine to the top of my old macbook pro. Today I plugged my new mackbook pro and TIme Machine asked me if I wanted to use it as a return to the top. I said yes, and the process has begun. Then I saw that he had erased everything I had previously on the external hard drive...

    so I stopped immediately.

    Now, my external hard drive is empty with only a couple of the new backup folders... and everything disappeared. Please help, I have all my work on this hard drive and very important documents.

    Thank you very much!

    Maybe this, I used it when nothing else worked, but nothing is a bet of 100%

    the more you use that drive for now more you'll destroy what could be there so disconnect now!

  • Migration of Time Machine to the new drive, backups are larger than the Original drive

    I am currently migrating my Time Machine backups from a 2 TB WD My Passport for Mac to a new WD 6 to my book for Mac. I have 63 backups on the old disk, and Finder says that the reader has TB filled 1.96.

    However, each individual backup is about 350 GB, which certainly does not. I think normally it was something weird with the Finder listing the wrong sizes, except that when I copy the backups to the new disk, they copy effectively to 350GB a piece. I initially tried to copy everything the ~ 2 TB Backups.backupdb at once, but it was so great, she didn't, then I copy on each both a backup in a folder that I had planned to rename "Backups.backupdb" at the end. At this rate, I will fill new TB cases 6 drive long before copying all backups on.

    How is that possible?

    Just to be complete, I'm using a Macbook Pro of the retina 2012, 2.6 GHz Intel Core i7, 16 GB 1600 MHz DDR3 graphics card Intel HD 4000 1536 MB, 512 GB of storage, under OS X 10.11.3.

    Time Machine saves the previous backups for the continuous backup size to become more wider until there is no more space on the backup drive. It is quite normal because Time Machine is an archive backup utility.

  • Using Time Machine or the Migration Assistant to transfer information from and old Mac to a new one

    I had to think about upgrading a Macbook Air to a Macbook Pro and have done research on how pretty much everything (files, account icloud, etc.) to move to a new computer so I know how to do it when the time comes. I didn't save my current computer at the time I got it and didn't know whether it was necessary to do it before the transfer. Also, I found two different ways to move information from one mac to another, one way being using the migration wizard, the other via the time machine. The problem is that I've never used time machine (I checked my settings and it is turned off). I was curious to know which option would be the 'best' way and if not never back up my computer would be a problem. (If its possible, could someone also please explain how to back up my computer?)

    Thank you for taking the time to read this and I look forward I hope to get a reply soon!

    I use Time Machine often (and have used since its introduction).  I also upgraded my Mac hardware quite often (about every 18 months).  Whenever I move to a new machine, I use the Migration Wizard (and not Time Machine).  I've never had a problem.

    Then I suggest that you need not Time machine specifically in order to change computers.  However, you really need to keep backups simply because the material is not, and without a backup, you are subject to lose everything you have on your computer.
