cRIO, Webservice (REST) and front panel

Hello

I created a few simple webservice screws for greater application that runs on a cRIO. The webservice screws can be used to send simple commands to the application and give your feedback. So far, I used a LV frontpanel for interaction with the system, but for several reasons, I am looking for another way to do it.

It worked well in the development environment. After deployment webservice screw they have communicated with the application according to the needs and I am able to control the system using simple URL typed in the browser's address bar. Later, I will add static content, but for debugging, it is fine.

The thing is that now I have compiled and deployed the application, and now when I try to open the front panel I get this error message:
"VI requested is broken and cannot be read or controlled."

Previously I did not use the Web OR Application Server, so I installed to use the web services. Are there conflicts between a Web application server and remote server Panel? Any suggestions on how to proceed?

I use LV 2012 and NI RIO 12.0

Best regards

Simo

Hi Simo,

If I understand correctly, you have the following configuration:

cRIO with a Web Service of LabVIEW and several Web Service screw

Some ways to debug deployed screws of LabVIEW Web Service are:

You can have the Service of the Web of LabVIEW deployed in debug and debug remote Web Service of LabVIEW desktop.

You can use a tool like factor to make it easier to apply and test your Web Service screw (similar to go to the url in the browser).

You can create LabVIEW screws of office using the Palette of HTTP Client to test the Web Service.

You mentioned the following"I have compiled and deployed the application, and now when I try to open the front panel... "

I'm a bit confused as this front panel you open. For example, do you mean that a LabVIEW project has been opened on the desktop, the Web Service of LabVIEW in the project has been deployed to the target of RT cRIO, and now, when you open the Web Service screw on the desk to look at the front panel, you get an error message?

  • HP EliteDesk 800 G2 Small Form: The front panel audio connector - this only made type to use for headphones and microphone

    Hello

    I am trying to determine what type of audio 3.5 mm plug to put into the connector on the front panel for the use of a headset to make video communications.

    could be - sleeve, ring and end cap (mono audio and microphone)

    or

    could be - sleeve, ring, ring and tip (stereo sound and microphone)

    Having read through the manuals and nothing is said on the type to use.

    Hello world

    Just plugged the connector 4 poles on my headset combination for my mobile phone (cellular) and the box of pop - up asked me to select headset or microphone - no selection for both.

    Looks like the right sleeve is for headphones only, and the left one is for headphones or micro - selectable by the user and not the two on a single sheet.

    Everything explained by the practice - but not the paperwork in the manuals.

    #5 for microphone or headset - menu popup is displayed after you insert a 3.5 mm plug to select that one but not both at the same time.  (So I can't use my headset to phone)

    Thank you

  • A way to group controls and indicators on the Front Panel and that they can be made Visible or not as a group?

    I would like to combine several orders and LEDs on the front panel in a group in a way that allows me to do the whole group Visible or not.

    I tried to use a Cluster, but it has a side effect that all elements must be inside the controls or indicators, but not mixed.

    Is there any graphic element, like a panel that can contain other controls and indicators on the inside and make them Visible or not as a group regardless of whether they are commands or the LEDs?

    Good suggestions on how to do this?

    Thank you.

    The tab control is still not my favorite, appearance but it's a way fast and effective to show and hide groups of controls and indicators.

I tried to install the Codec AC 97 drivers for Windows 7 and they do not work for Windows 8. The 'High Definition Audio Codec"Windows 8 drivers only work for the Ports on the rear panel, not the Ports on the front panel.

    How can I get AC 97 Front Panel Audio and Microphone ports to work with Windows 8?

    Hello

    Your model has not been tested for the use of Windows 8.

    For this reason, HP cannot provide instructions to upgrade or Windows 8 pilots.

    Therefore, it will be very difficult to provide a solution.

  • Swap sides for the scales on the front panel and containers

    Hi all

    Very simple question here. I want to Exchange on sides of the balance on my Front Panel and specifically DSC container as a pressurized tank.

    It is very easy to do with a waveform table or chart, but seems to be impossible with tanks and reservoirs.

    It would be very convenient, especially for the process of DSC where I try to imitate the flow of process on the front panel and pipes could enter tanks of different sides.

    Thank you!

    Here is a tank with the scale on the right. Just took a few minutes with the control editor.

    The computer in the oven must LabVIEW or LabVIEW Run time engine. There was not a "Viewer" for many years.

  • Best way to reset all controls on the front panel except one?

    Hello world

    I have an interesting problem, whereby I need to run successive tests using a test station which has several indicators on the front panel. At the end of each test, I need to reset all to default values, with the exception of a control (Test ID) who needs to keep his information - its value is used in an initialization status for test to ask for information from a database, so it can not be reset with the rest controls.

    I post all orders at a time using a reference ThisVI and VI Default Vals.Reinit All method, but this will obviously reset my control values (Test ID) as well. Any suggestions on how to keep properly or may store this information control while resetting all others. I can reset individually others but there is a little and more can be added as this system is developed.

    I don't really know what is the right way to proceed, and Labview has maybe one trick in his bag that I know to work around this problem.

    Thanks in advance for your suggestions,

    Alex

    Flank the node invoke with two nodes in the value property of the control to maintain the value. To the left we read as well as a right and the wires together. Connect three nodes with a thread of error to establish the order of execution.

    First reading place value on the wire, which is then written after the values have been reset to the default value.

  • WANT 411c: MFP ENVY 411c lights on the front panel

    I find anywhere a note detailing the two LEDs on the front panel of the printer.  Of course, the left is the power light and the Start button / stop.  The other, 1/2 "to the right, has an icon as the icon of WiFi or wireless, or whatever it may be as an antenna with a radiating signal left and right of it.  What is this for?  It seems that there is a hole below and to the right of the symbol, but nothing ever shows up.  I turned off the wireless and turn it back on and or State shows a light here.  I reinstalled the software checks to see if that mattered and it made no difference.  I also unplugged the router and the printer, and that has not changed anything. It is connected to my wireless network and works very well.  What this has to do with some additional services such as ePrint?  I just lost some of them September 1, 2016.  Perhaps the only light when something just one of them?

    Hello

    That your work as expected wireless connection, there no problem with the wireless printer, just with his lamp wireless card.

    The lamp to indicate the wireless connection is turned on and must turn on once connected wireless.

    They have nothing to do with ePrint or any Web service, it must turn on once connected to a local wireless network.

    As you mentioned that you are connected and the printer maintain a wireless connection, it's probably just a blown bulb.

  • Satellite L500D - what is that annoying red light on front panel?

    Hello

    I have my L500D the normal five system LEDs on the front panel of the base computer, where they are supposed to be. But then, to the left of these fires, there is that annoying red light, which is very distracting.

    But what is even more annoying than not one, + not a + manual owners I've read mentions none, + not even a hint. The manual mentions the other lights in their patterns, + but not this one. :-(

    Now, I'm assuming it's something really simple, and I publicly show how blind or stupid (or both) I really am. :-) But for love all holy, and before that I lose all of my hair, can someone tell me what is all simply as the red light?  :|

    And, while you're at it, maybe you can tell me how to turn it off! It would be a very unique experience for the moment. (B-)

    Don't get me wrong, I love my new L500D, my best investment by far and it goes like the wings and I write about a wacky ad jingle and broadcast around the world... If not for the boring red light. ;-)

    Help, please! (i)

    Hello

    I think you are talking about a wireless light located on the front left side of the computer. You can see here:

    http://laptops.Toshiba.com/laptops/satellite/L500

    Yes, it's a little boring, but you can turn it off by pressing Fn + F8 but in this case the wireless connection turns off. As for me, I use any wi - LAN, my knees is connected to the Internet by cable, and I never use outdoors.

I don't remember if I already had the cabinet apart one more than this. The front panel can break, but I fear I will "break the BAD thing. I'm sure that WD - 40 or other cleaner used by switch electronic only should be OK. Thank you all for help.

  • Satellite A200-1N1: "Satellite" LED on the front panel does not light up

    Hi people!

    I noticed that my LED with the word "Satellite" on the front panel lights.

    You have all the hypotheses on the causes?

    Hi Maresha,

    The front 'logo' LED is enabled or disabled using a BIOS "Display front Logo" option that can be set on IT or OFF you need. Access your BIOS settings (F2 at startup) and check that this setting is set to 'ON '.

    Kind regards
