A witness flashing without property node

• enable all controls without property nodes

  On my FP, there are controls/indicators that are in the hidden state.  I know that I can make them visible with the nodes properties.  However, I was wondering is there a way to do it with just a few clicks?

  While in the development environment or execution?

  In the development environment, you can right-click on the terminal on the block diagram and select 'Show Control'. Unfortunately, you cannot select multiple controls/indicator to perform this action. I think he had an idea submitted to allow this, but I'm not sure.

  In the run-time? Laughing out loud

• Visible property node question

  I need to enlarge the various controls on my front and disapper with function of what is done is there an easy way to do a lot of different things appear and disappear without creating a node property for each individual. His slow me down a little during the execution and the sound also make my huge primary VI.

  Try to create a table of references to the things you want to make visible/invisible, and then pass this array in a loop with a property node inside. This should make you save a lot of space to block diagram.

• Error: The property node (arg 8) visa to configure the Serial Port

  I'm trying to control 8 USB to R232 via a HUB of 10 ports Tripp-Lite (model U222-010-R) and do not have consistent results.  Just after rebooting my computer, I have no problem in running the following program: (I tried to download the VI directly but without success, so here's the extract)

  

  I made sure that the COM ports that I select are that one is available on both the Device Manager and in the NOT-MAX.  But after awhile, it does not work or if the HUB is unplugged and replugged in (even if the names are correct and up-to-date in devices and NOR-MAX Manager) I get the error code "property Node (arg 8) visa set up a Serial Port (Instr) .vi" I want to be able to see these ports consistantly more without having to restart my computer all the time.  Is there a better Setup for this? The previous installation of the computer has a PCI card for it and we have not had any problems with the code, but are facing problems with our upgrade.  The old computer ran Windows XP and had cards PCI and the new computer that I am using a Windows 8 and the USB HUB.  Thanks for any help you can give!

  Mr says:

  Jeff,

  It is a one off lines from specifications Tripp-lite:

  -On bus power, 500mA from the USB 2.0 computer port is shared between hub ports

  This would be in support of what I need or not necessarily?

  -Mr

  No! That's the 50mA by port not 500mA.  an order of magnitude full powered USB (if you want reliable - if you want real problems which appears irratically each time only and is a headache to track down which would)

• RT - property node error 1055

  Hi all

  Currently I develop an app RT on LabView 2014 SP1 which consists of three parts:

  • A PC vi that read the data and sends it to the target of RT;
  • A RT vi running on the CRio-9074 which receives data, convert it to current values and send it to current output modules. It also sends PFGA a number of pulses must be generated.
  • A FPGA target that receives a number of pulses to be generated and then do the work by a module ttl

  Things will work perfectly when the RT vi cover is open on the PC. This happens when I enter debug mode simply run the vi RT of the Project Explorer.  The problem started to happen when I tried to run the program without the RT vi front open. After some research, I discovered that the application of the RT was generating an error 1055 in a stream property node. The strange thing is that this does not happen while the RT vi façade is displayed on the PC!

  Althouth it seems to be a problem known as I found on the Web site of NOR, it is not clear for me, how do I solve the problem. Should I just close the RT VI, open it, close the vial, compile and deploy it finally? Well, if it is that means that workaround, it did not...

  537230 Return

  Changes to the VI with dynamic references breaks VI with the error-1055 the Node property When a VI deployment that allows to get a dynamic to refer to a control on a x 64 Linux target in real time, the VI deploys successfully. After you make a change to the VI, error-1055 is thrown from any node property is trying to access the dynamic refnum. The error says "error-1055 has occurred to the property node...". » Workaround: Close, and then reopen VI. Report version: 2014 SP1    Solved Version: N/A    Added the: 23/07/2015

  Thank you all for the help. I use a few cards in the RT vi and was the use of the nodes properties to clear the history. These cards are only for the control of the application while it is still in development, and it worked fine while I ran the RT application with its façade exposed on the PC screen. At the moment I leave be executed only in the CRio, he started planting and throwing the error 1055. I removed the nodes properties because they are not indispensable and everything works fine.

• How to create a specific property node w / script of VI

  I am writing a VI script to work with multi column list boxes.  I need to create a property node that gets a reference to the REF field.  I see that I can create a property via the method invoke Create.Property node node node, but how to get the REF field specifically I have so far can't understand.  Can anyone help?

  To be clear, I write code that looks like this:

  

  .. .and when I run the script, I want to produce this:

  

  At the time current it produced as planned MCL, via the node of the new VI object... but I don't know how to get the Ref created automatcially.  I thought that it would be in the table PropItems, but so far without success.

  Thank you

  "PropItems []" exit will be a table in a single element.  This element of the index and the reference to a node to invoke the wire.  Select the mode "SetProperty".

• MCListbox property node does not during execution

  Hi I have problem with MCListbox property node. I wanted to fill the column with names and elements in the table.

  Initially, the program runs smoothly under development without error time.

  However when I she ran during execution of the table cannot be completed and produced by mistake. The error that says that "[get article] Config Registry.vi data: invalid object 0.

  I'm not sure what the error means that I need to find the bug in the moment of the execution because it works very well under development time. I found MCListbox property node errors after the names and elements are tempted to be filled in the table. I don't know why there are errors to the difference in time of development. See attachment below

  

  Thanks please advise

  You read data from the configuration file? How do you get the path that it? You know that there is a difference (http://digital.ni.com/public.nsf/allkb/FD7DE8BC8FFC256C862565F4006BE363) between the path to the runtime and development environment? What LV version do you use?

• Property node enabled even if it is removed from the diagram

  Hello

  I messed around with the property of one of my tests node and when I had finished and removed the property node the block diagram it's always my control blinking.

  How can I stop?

  The option to enable State is not possible in mode of property node. I turn off and active in gray.

  Thank you.

  To stop the flashing:

  1. Create the node property flashes again.
  2. He lead a constant False .
  3. Run your VI once.
  4. Remove the property node.

• LabVIEW 7.1 IVI - C Wrappers and VISA property node do not work together?

  Hello world

  I want to use the property node VISA with LabVIEW 7.1 Wrapper of two companies different well known instrument, Rodhe-Schwarz and Agilent Technologies.
  The two companies releasead their IVI - C for NI LabVIEW 7.1 drivers version NI Instrument Driver network and they are ready to be installed and used.

  I found a bug manifested that the LabVIEW 7.1 version that the bug is not present in whhen versions 8.0 LabVIEW or LabVIEW 8.6 than these IVI LabVIEW of LabVIEW 7.1 wrappers are used.

  Everyone could exeperience this bug if they have LabVIEW 7.1 installed and are trying to use the version of LabVIEW 7.1 of these wrappers which are published in NI Instrument Driver Network under the links below.

  Agilent ag81150ni IVI Driver for LabVIEW 7.1 install from here. Used in simulation that by definition simulate = 1

  http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=55798957B1A633BDE0440003BA7CCD...

  Rodhe Schwarz rsngpt IVI Driver for LabVIEW 7.1 install from here. Used in simulation that by definition simulate = 1

  http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=E3B19B3E91D6659CE034080020E748...

  After the installation of these two complete drivers close LabVIEW 7.1, if it was open, and then restart LabVIEW 7.1. You can see two new ready to be used as LabVIEW 7.1 IVI drivers in the LabVIEW Instrument Driver pallet wrappers in a LabVIEW 7.1 VI test.

  Open a new white VI and of the use of the Instrument Driver Palette two VI known, initialized with Options.vi and Close.vi adding them on the block diagram, connect all THMs. Accept all default settings except simulate parameter which must be defined as = 1 simulation.

  The two VI run OK mode of simulation without errors.

  Now select a property in the advanced Panel of VISA node and press this node between 'Initialize them with Options' and 'Close' VI and make all necessary in-out connections and error.

  Run these two simple screws of simulation

  1. When I run pilot Rodhe Schwarz IVI the property node going OK until the end. No error
  2. Whne I run Agilent IVI driver the property node is always out of the error Code 7.

  Question is why they behave different with regard to the property of node when it is used with the LabVIEW 7.1 envelopes? BTW, the failing VI of wrappers Agilent LabVIEW 7.1 works very well in labVIEW 8.0 and 8.6. That means that this problem is limited only the version of LabVIEW 7.1.

  I posted the same question on the set of LabVIEW and nobody chose their interest in there so I decided to post here. As this question is also linked to IVI, VISA drivers, it is possible the person of this group to get a clue about this annoying behavior.

  I've attached screenshots of the PNG files that show the difference of different behavior of VISA property between these two drivers node.

• Property node "DAQmx system" global channel does not read changed MAX global channel of data after the 1st round

  I use the property system DAQmx node to read all the data the scale for global for thermocouple in MAX I use MAX 4.4, LV7.1.1, with a SCXI chassis in a PXI-1050 chassis. It seems to read the properties very well on first run. However, if you then change a channel property overall Max (for example a ladder or a type thermocouple factor) and it saves to the MAX, and then runs again the property node, it still read old data Max. To get it to read the changed data, it must close the VI, and then reopen it. It's painful when you recalibrate a vast set of thermocouples using MAX.

  Is it possible to force the node of system DAQmx property to reread MAX whenever it is executed, without closing his VI?

  See attachment. Run called standalone VI... PRINCIPAL. See instructions on the VI.

  Thank you

  Hi Tim,.

  Your main VI has not been updated is because you do not clearly the task after every time you call the DAQmx property node.

  Attached is a modified version of your code that works. I just added the Task.vi clear DAQmx in the FindChanProps.vi.

• Property nodes are all seriously affect performance

  LabVIEW gurus,

  I'm running continuously in some serious performance degradation by using nodes property to update the attributes of the objects of the public Service. A classic example is attached.

  I have 8 plots XY which are fed 600 SGL tip all the 200 ms - one very modest flow. Each plot is a dynamically instantiated .lives placed in one of the 8 sub-panels in a container of VI. The VI container also acts as Server data for charts, each of them sending their data in the queue for their own unique item. The entire architecture works great (~ 4% CPU load, see attached picture) until I by updating a node property to display the value of the value of the cursor there. When I activate the property node 'Caption.Text' of the XY graph to display the value of the slider, the CPU usage rises to more than 30%.

  As an aside, I'm developing on a platform of 2.1 GHz dual core with 4G memory with LV8.5.1, and the target machine is not nearly as strong. That's why 30% CPU on my plant is a problem - it essentially brings the target incorporated to its knees.

  I've included an example VI to run on your machine. Think of it as 'representative' of my biggest problems. The VI series update the CPU without the legend about 10% and 20% with updates of the legend.

  Finally, I tried to put the screws in the system of execution of the user interface. I also tried to postpone Panel updates, but this actually slows performance.

  Best regards

  Use captions only for noncyclical display. With the help of a text indicator should solve the problem.

• Graph plot legend colors Signal not updated when mixed with the property node

  Hello

  We try to put the colors of the trace of a graph of Mixed Signal using a property node. Although we can change the color of the data in the field correctly, the colours of the plot in the legend do not change until some apparently unrelated operator action is performed (for example, to resize the window or by double-clicking a field name).  Waveform to XY charts don't seem to have this problem.

  Anyone know a work around?  I think I saw a similar topic on the forums earlier, but I'm sorry that I am unable to find it now

  See attached vi.

  Thank you

• Error: The property node (arg 1) in .vi VISA set up a Serial Port (Instr)

  Hello

  I've seen people once they have gotten this error, but none of them really apply to my situation.

  Right now I use LabVIEW example code to read from a device manufacturer. This device is connected using a Tripp Lite USB adapter series (http://www.tripplite.com/en/products/model.cfm?txtSeriesID=782&txtModelID=2430) for the connection from the PC to device with RS232. The adapter works fine when using the software prepared in advance (not LabVIEW) given by the manufacturer and the COM port is seen by LabVIEW. When I run the program, I get the property node (arg 1) visa set up a Serial Port (Instr) .vi (I've also attached the VI but it's a standard VI I got of LabVIEW). I get this error despite the fact that I use the same COM port, who has worked with the manufacturer's software.

  I have attached manual of Protocol RS232/debit BUS (not sure if this applies) that requires the device. The device is a mass flow controller whose operating instructions is: (http://nemu.web.psi.ch/doc/manuals/device_manuals/Bronkhorst/917023--Operation%20instructions%20digi...

  I'm using LabVIEW 10.0.1

  Any help is appreciated

  Try to restart the PC and then try the LV version before trying other software.

  I have seen thrid party serial interfaces work on the first try but fail when you switch to another application. It was as if the pilot did not know that it was no longer the first process.

• Issues related to the cell property node: Position Active for a table control

  Hello

  What determines the Position of the Active cell in a table control property node? I have this in my code and display the value of an indicator on front panel. The displayed value is always set to 0,0. Help for the property node says it's "read - only" so what defines the Position of the Active cell in a table control value?

  Define you the active cell with a property node.  Once you select an active cell, you can do this cell and single cell-specific things, things like the background value color.

• How to change the value of the array element by using the property node

  Hello all :)

  IM using a table in the drop-down list box. the size of the array is not fixed.

  I want property strings [] from the drop-down list box to enter text in selection, but since I placed it inside the table im unable to use this property.

  I used 'arrayelem' reference property and property node connected to it but got no strings [] in the selection.

  so is it possible that I can use property strings]
