Can you have multiple nested DAQmx writing VI?

Hello everyone. I'm pretty new to Labview and am trying to find the best way to manage several instructions 'if' using a table of clusters and outputing to the various pins on a data acquisition module. Going to work to have a dozen DAQmx live write in the nested case statements, or will it cause errors?

The goal is to take the entries by the out of control and front panel based on schedules and user input values. Any suggestion would be appreciated.

I thank very you much in advance!

James

Of course, you can have several writing VI DAQmx.

Here is a tip that will save programming time you:

The Index Array feature is re-sizable!  You don't need to break a wire table and 4 tables to Index and thread of the constants for each of them to get the individual items.  Just drop a, and then drag the bottom of the knot to the bottom until you get 4 outputs.  By default, they start at 0 and increment by 1 when you get off.  You will get the elements 0, 1, 2, and 3 without having to associate the constants to the index entry.

I also recommend that, instead to use local variables, you keep the table of boolean in a thread that runs through all cases in a shift register.  Just replace the item array for any element of the array you are editing in a particular case.

I have also modeled the code, you have no need for dozens of instructions box nested.  For example, you have one ON and OFF cases in one of the nests.  I'm assuming that the only difference is that you are wiring is real or fake.  Wiring just the Boolean value.  Various other code is duplicated between each case.  The same for the upper levels of the nest.  If you write to the acquisition of data in all cases, who move outside the structure of the case and just control what Boolean values to change the Interior structures of the case.

  • Can you have multiple forms of contact in a single site of Muse?

    I have a site created in the Muse who need to use multiple forms of contact of a sort.  One is a simple contact form.  Other two are sign up forms. In two of the three forms, I have to separate the first and last names.  Also in people there are several custom fields and Message fields.

    The original simple contact form works very well and has been.  However, I modified a page by adding a second form, the first of these two forms of registration.  She was beautiful in Muse, but when the downloaded from the site, all fields have disappeared, leaving only the labels in a single paragraph.

    Is this to say that I can't have contact multiple forms in a single site?  If I can, then what might have caused the problem?  And what would suggest you for me to try to fix it?

    Thank you

    Hello!

    Can I have multiple records of ra_interface_distributions_all against a ra_interface_lines_all record?

    Thank you.

    I was able to create multiple lines of distribution for a command line. Just ensure that the total amount or the total percentage of distribution lines is equal to the amount of the line or per cent = 100. You use either amount or percentage based on what is found on the source of the transaction-> account assignment of revenues.

  • Can you have notifications to both your iPhone and your Apple Watch?

    Can you have notifications to both your iPhone and your Apple Watch? It's a problem for me if I am away from my iPhone and my Apple Watch does not receive the notification.

    Hello

    How notifications behave depends on the State of your devices. In order to provide notifications to your attention as soon as possible:

    -If your iPhone is unlocked, you will receive notifications on your iPhone instead of on your watch.

    -If your iPhone is locked or asleep and that your watch is unlocked and on your wrist, you will receive notifications on your watch.

    -If your watch is locked or allowed to do not disturb, notifications will be sent to your iPhone.

    About notifications on your Apple Watch - Apple Support

    You can see that if you turn off your wrist detection (on your iPhone, in the application of the watch, go to: Watch My > General > wrist detection) it will make all notification alerts to be delivered to both devices. However, you will not then be able to benefit from features including Apple pay and one unblock after placing the watch on your wrist.

    If you want Apple to consider adding an option for notifications to be delivered for both devices regardless of the other settings, you can suggest to Apple here:

    Can you have records in your image folder and the images still be seen? I have a graphic file with images and they can be seen on the site, however if I insert files in the pictures folder, the images are not displayed, are what I did or is not possible with dreamweaver?

    I.e. graphic > pendants > outdoor shots.

    Inside or the other of the two last records images do not appear on my site!

    Images can be shown no matter where they are in your site. The only downside is that you have a working image link.

    For example, Graphic/Pendants/Exteriors_Shots/myImage.png note underscore in the path. This is because many browsers interpret too much space. This means that your subdirectory should be renamed accordingly.
