The MAX properties of the device button is disabled / grayed

Hello

I am in the process of commissioning of a Labview test bench controlled so looking for conditions in which the system can become dangerous.

If I simulate a computer/software crash by stopping LabVIEW (using the windows Task Manager) exits Digital remain frozen in their last State before shutdown. I need them all to become 'low state' (off) because that would make the safe test bench. How can I do this?

After doing some reading, I tried to define the type of MAX, by going to the INTERFACES AND DEVICES, select the device, and then click PROPERTIES. However, the properties button is disabled / grey so I can't access the properties.

I use the following software versions: Labview 8.6, MAX 4.7.1 and NOR-DAQmx 9.2.1

The material is: cDAQ NI9178 (chassis) and NI9481 (electromechanical relay module).

Thank you very much

Loss of power of the computer, the relay will revert to their default open State.  Even if the device is disconnected from the computer.  This is where the power is connected to the computer, but the application crashes that you will need to take another way to reset the relay.

  • Event of exit/close application trap on exit/return of the device button

    I developed an application in Sib. I want to intercept the output/closing event of the request so that I can ask the user for the confirmation message.

    It may happen that the user will click the back button on the BB device accidentally. If I don't want it of happen and will show the confirmation message.

    There are a variety of ways that you can incorporate it, but I don't know of a hook that will let do it without changing your code.

    The following suggestions can help you change your code.

    (1) If your application has a home screen, i.e. that it all comes down, then override the close() method and replace with your dialogue.  If the user wants to get out, then call super.close ().

    (2) If you have several places that emit the system.exit(), replace it with a call to your own method of "release manager", that shows the same dialog and emits only the system.exit() if confirmed.

  • My computer or Windows Exployer do not recognize my CD/DVD equipment. I checked and the best driver currently installed, but the device is apparently disabled. Help!

    I went into the properties of the device, but could not find a solution.

    Hello

    Please make all below even if you have done some before as it is often the set of operations which solves
    the question.

    Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
    Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
    This will refresh the default driver stack. Even if the reader does not appear to continue below.

    Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
    slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    Hope these helps.

  • Anyone see the option to transfer disabled/grayed out in the latest iOS 9.3.1?

    I used handoff successfully for a long time until this week. All the settings on Mac are correct for both 9.3.1 iOS (iPhone 6 Plus) and MacOS 10.11.4 have the same credentials to iCloud. However on my iphone iOS, the transfer option (under settings > > General > > Handoff & App Suggestion) is grayed out. Have power rolled my phone once or twice without success.

    Also I was wondering, and by checking with my enterprise IT if MDM provisioning profiles limit the transfer feature? To prove otherwise, anyone else seen this problem? I did a google search and see no others have reported the same problem.

    You say that you rolled your iPhone power nothing works. Did you do a reset? Hold the sleep and wake buttons at the same time... continue pressing the two buttons until the Apple logo appears. This usually fixes most of my problems.

  • Cannot use the fx button to disable the effects.

    I think that you will get a lot of benefit to visit this page.  With After Effects, you must start at the beginning or endure unnecessary hours (or more!) of frustration.

    To answer your question directly, you do NOT apply an effect.  There is no indication of an effect in the column of fx switches Panel, which is visible in your screenshot.

    Hi herschen,.

    Welcome to the community of Sony!

    Perhaps the question is just the driver. We will isolate the problem by following these steps:

    • Power cycle - turn off the laptop-> flip the unit and look for a button cell or a pin hole on the bottom of the laptop. Using a safety pin, press and hold the hole for 5 seconds.

  • Bluetooth has disappeared from the Device Manager

    My computer does not detect bluetooth devices. I went to the bluetooth menu and unchecked and rechecked the boxes 'discovery' and so on. However, when I hit apply, the window became unresponsive and I forced to close. When I tried to repeat this, when you type apply I get a Bluetooth Service error message saying my device is disconnected (my bluetooth adapter is built-in).

Now I have no bluetooth, the 'other' device any device and can not use bluetooth. I tried everything I can think and find on the net (reboot), update, etc.. Help, please!

  • How to activate the new button in the Workbench of invoice in Payables in 12.1.1

    Hi all

    In accounts payable, the new button in the workbench invoice showing off.
    I use 12.1.1 version.
    Could someone please help me how can I activate this new button.
    I am creating the invoice through workbench invoice no quick Invoice window.

    Thank you

    Hello

    This could be due to several reasons...

    Reason n ° 1 = you only access and not allowed to create invoices

    Survey Navigation responsibility for accounts payable = > bills > inquiry > invoices
    Entry Navigation responsibility for accounts payable = > bills > entry > invoices

    Reason 2 = explode on navigation ENTRY you always see the NEW button is disabled, this means
    accounts payable system does not allow the creation of individual bills, you must create only in batch mode.
    Check the value of the profile option ' AP: use invoice batch commands. If the value is YES, it is intentional that NEW button is disabled...

    Reason 3 = you use Navigation entry, your responsibility is not enabled for lots of bills
    The Bill create function could have been excluded from the responsibility...
