Property node invalid error

hi all,
i am transfering my application(for HP 4284a) from my old computer(windows 98 and labview 6.1) to a new one (windows xp and labview 8.0). A repeated error occured.
Property Node: invalid property.
Someone told me i have to change the property from Range to Range2 for the Excel Worksheet Node in my program. But as can be seen from the diagram, the list only has Range and no Range2.
Attached are print screens of the error.
Any further information required can tell me. Please help. Thanks.

Hi wjsd
It's not the Range property that is wrong, but the Value property. Use the Value2 property to read/write values from/to Excel.
Hope this helps

Tab Control Property Node unknown error on TPC

I am using Lab View 8.6. I am programming an HMI onto a TPC 2106. I am using a Tab Control and it workls fine. The problem is when I add a property node for the tab control to the block diagram. I get an unknown error no matter which property I choose or if it is read or write. I tried it on a vi destined for the computer and it works fine. It seems to be an issue with the TPC 2106 as the destination.

Hi vrundquist,
When compiling a VI for a TPC, there are many properties of controls and indicators that will not be supported. Which properties specifically have you tried? I want to be sure you are choosing a property that should be OK. For example, try the Visible property. Also, is there anything else going on in your code, or can you reproduce this with a VI that has nothing but a tab control?

Property node standard error in functionality - odd behavior

I am getting what I would consider unusual behavior from a property node when there is an error on the error cluster input. The Help for the VI indicates this node has Standard Error In functionality, which I interpret as if there is an error on the input then the node does not run and the error is simply passed through to the output.
The behavior I'm getting is that the error gets passed through, but the properties of the node also get passed out with the data that was present the last time the node was called (including when it wasn't this specific node, but a different property node within the same VI that has the same property outputs).
In Psuedo code, this is what I'm doing:
Use Invoke node to call a method from a DLL (which sends a command to a device and gets its response).
Pass the method reference to a property node, which then outputs the properties of the method (the response from the device).
This works fine when everything is as it's supposed to be (device I'm communication to is connected, etc.).
If I disconnect the device completely and then run the VI again, I get the property outputs from the previous communication out of the property node, which are obviously not valid as the device isn't even connected. This happens even if the command I sent to the device is not the same; Command1 is sent and gets valid response, disconnect device, command2 is sent and I get response for command1 from the property node of command2. Command1 and command2 are in different cases of a case structure.
At first I thought there might be an issue with the DLL functionality (and there might be) reporting stale data, but before that is even an option it seems the property node shouldn't even be possible to have data output when the node is supposed to be bypassed entirely when an error is passed in.
Is this supposed to happen? Am I missing something?

Coincidentally, this week I ran into what appears to be the same behavior with the Scan from String function, and I thought of this thread. It doesn't help solve your problem, but maybe it's useful to know that this behavior happens in other built-in functions, not just Property Nodes. I started a new thread to look at this more generally.

I get error 1055 "Object Reference Is Invalid" when I try to write to a property node

Hi, I'm trying to get these results to be displayed in two tables now, where I originally had them being displayed in just one. Outside of the attached vi, I can just copy the value property from one table to the other after this vi has run, and the table values appear properly. The problem with that is, that any table property I assign (changing background colours to be exact), is not considered part of the value property, and thus isn't copied when I copy the value from one to the other.
The thing I can't understand is that the second set of property nodes (at the bottom), give me the "Object Reference Is Invalid" when I added them. I've tried everything I can think of, but can see no logical reason why I get that error for those two, while I don't get the error for the top two (not wired to constants).
Any help on this would be much appreciated. Thanks
Geoff

The logical reason that you're getting that error is that you are not passing in a reference to Table In Two. The control is not wired to the connector pane so you are not getting a reference from the calling VI.

Error 1055 occurred at Property Node : Object reference is invalid. This Error occurs only in built application

I am using a WaveformChart to display multiple traces of data, the number of traces is variable, I use property nodes to set the number of traces and whether the digital display is visible or not, as more data is available the number of traces is increased and the digital displays are made visible. Within the Labview design environment everything works well. However when running the built application if two or more traces are to be charted I see error 1055. I suspect it is related to making the digital display visible on two or more waveform traces. See VI attached.
Why is this error happening ?
Thanks.

Two traces

WF Charts only create their plots at development time.
If you attempt to access a plot that was never there you get that error.
To work-around this detail, simply size the legend for more plots than you ever expect to use at development time so that the plots are created and availabe when you do the build.

NI 845x USB: Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi

Hello,
I am currently working with digital accelerometer LIS35DE from ST Microelectronics. I want to start with tests of this device. For that purpose I used NI 845x USB to connect with accelerometer via I2C. Unfortunately, when I made electrical connections and set up parameters of communication and run the program (I found it in examples) the following error occured:
Error -301713 occurred at Property Node (arg 2) in General I2C Read.vi
Possible reason(s):
NI-845x: An input parameter, or combination of parameters, is invalid. An example of this error may be setting an invalid baud rate or enabling I2C ACK polling while using 10-bit addressing.
The code can be found in attachements. I couldn't find any extended description of this problem. What could be a problem: incorrect device address, register address, configuration parameters?
Any help is appreciated!
Best regards,
Michael

Hi MicMac89!
First of all could you please post which version of LabView are you using?
Could you please tell me which version of 845X hw are you using? (8451 or 8452)
I opened the example you attached. As you wrote the error occurs at the second argument of the property node. (I guess this is the first property node where the error occurs.)
This argument of the property node enables the onboard pull-up resistors. But not all NI-845x hardware support pull-up resistors. (Because of this is important to know which hw version are you using.)
Did you try the example with disabling the pull-up resistors?
I suggest you to go through the Manual of this product, (if you did this not yet) This could make it clear where and when to use what kind of pull-up resistors.
For example: If you are using 8452, you must enable pull-up resistors, for Vref ≤ 1.8 V for the FPGA to properly detect a low-to-high transition

Please post if my suggestions helped. Of course if you have any questions, don't hesitate to post them.

Error 1055 occurred at Property node

Generating the error:
"Error 1055 occurred at Property Node in ... Possible reason(s): LabVIEW object reference is invalid."
when I try to wire the IMAGE OUT output from the IMAQdx Snap vi to the value property of an externally referenced image display control.
To describe in more detail, I have a parent vi with an image display control and a child vi which has a control refnum linked to the parent vi display. In the child vi I create a value property for the refnum and try to write images to it, essentially to drive the parent display from the child vi.
The technique works elsewhere, though I can't think of what I could have done differently to generate this error?

Hi Mike - looks like I may not need to. I've been working away at this and have found the original cause and something else a bit weird...
I deleted the objects from the sub-VI that was giving me errors, then cut and pasted the objects (image display refnum and value property) from a VI that was working and this solved the problem. So you might think that the issue was just some obscure configuration item, or I'd used the wrong type in my reference or something.
I found the display reference in the parent VI was not even wired to the sub VI - duh! Error between keyboard and chair. So at least the original error message made sense, but I have no idea why it actually worked after pasting in the new objects. Are these references using some sort of auto-magic? Who knows. Safer to wire up my sub-VI's properly methinks.
Sorry for wasting forum time on this one.

On cRIO-9033, property node: Owning VI Reference is Invalid

I am starring for the first time to work with a UI on cRIO-9033. The code I am trying to adapt to work on the RT is working on Windows just fine. But when I put it on the RT it throws errors. I looked through the code and I kept getting error 1026 Reference is No Longer Valid. I made a very simple code to try and run (as linked below), and it throws the same error.
When I probe the error coming out of the VI Property Node: Panel, it gives me an Invalid Reference Error. Nothing closed the reference and the VI is obviously still running and in memory since this is the VI. I'm not sure what is wrong. Could it be that I am running it from development environment? Or is this a quirk with programming in Linux?

I found another bug. You just to follow my instructions if you don't mind
Open the attached code
Run it. It should work fine
Move anything on the front panel and save it
Run it. You should get errors.
I'm not sure what is wrong but I can reproduce the problem over here.
BEFORE IMAGE
AFTER IMAGE
notice the I moved error out 2
Actually on my more complicated example the property node giving the panel references passes invalid references all the time. Not just when I resave it.

Error cluster in XControls Property node

Hello!
Property Nodes of XControls do have Error Clusters, but how can I change those out of the Facade? I'm setting an object through a property node for tree data. It is possible that some of the object methods generate an error while executing in the facade and I would like to catch this error in the VI containing my XControl.

You can't change the error output from a property node from within the facade since the facade only gets called after the property VI has run and modified the contents of the display state information. If possible try to catch invalid values in the property VI itsefl. If there are errors that the xcontrol will need to report you will need to provide a separate mechanism.
Something that I have used in the past to good effect is the idea of an error stack. The error stack itself is an array of error clusters that resides in the display state data and is maintained as a circular buffer by the xcontrol code. To access this value from the calling program create a read-only property that reads the contents of the buffer and then clears it.

Display Property Node Error 1077

I have created a vi with multiple analog inputs (up to 20), and I want to be able to turn plots on and off on the front panel. I currently have this case structure set up to go through each input (i through N), and the front pannel array (LED buttons) can be turned on and off to choose which plot to display:
Turning the plots on and off work, but I am getting this error message:
Error 1077 occurred at Property Node (arg 1) in NetworkAnalyzer_UpdatedDAQmx.vi
Possible reason(s):
LabVIEW: Invalid property value.
Property Name: Active Plot
Any solutions? Thank you.
Solved!

Are you sure the number of elements in the Boolean array matches the number of plots you actually have? That error implies that you have more elements in your Boolean array than you have plots.

Property Node in VI throws Error 7 in LV 7.1 but runs OK in LV80 and LV86

Hi everybody
I build a custom IVI instrument driver and using the LV tool <Generate VI Interface from Instrumnet CVI Driver> I was able to get a LV wrapper for each driver method. From LV86 I saved first in LV80 and from LV80 I saved as LV71. I have all these LV versions on installed on my PC.
I have no trouble in using these LV wrappers in any of these LV versions as they work OK.
Now my IVI driver has also Properties that the Import Driver Tool does not convert as a wrapper and for that reason I had to create a Property Node Warpper myself and saved in the same LLB under LV/instr.lib folder.
Once I have all these method wrappers and the property node wrappers I made a small VI
1. Initialize IVI With Options on a TCPIP instrument
2. Set-Get an IVI Timeout property
3 Close IVI driver on TCPIP instrument.
Good part is that in LV 86 and in LV 80 the VI is running fine when I use these LV version wrappers from their coresponding instr.lib folder.
As soon as I am going to use the LV 71 wrappers in LV 71 I could create the same small VI to Set/Get Timeout and the VI look OK nothing is broken but when I run it the Initialization is OK but as soon as is reaching the Timeout Set Property Node gets out an Error Code 7.
To run this VI the user need to install the jdCMR IVI driver then add the LV71 jdCMR wrappers inside LV71/instr.lib and then he may build any VI using these LV warppers.
The only problem is that the Property Node get out an Error Code 7 and the same error code get out from Property Node if I am picking the Property Node from VISA Advanced Pallette, connect this node to jdCMR driver, set Timeout property inside the node and after connecting the input and output references plus the input and output error to Initialize and Close LV wrappers I still get this error at running time.
The same LV 71 VI if I open in LV80 or in LV 86 runs without any problem?
Does anybody knows why LV 71 is not working the same way as LV80 and LV86 with respect to Property Node?
Btw When I save my VI from LV 80 to LV 71 I get this warning...

Hi
For further testing of the IVI driver Property Node bug with LabVIEW 7.1 IVI drivers I download and installed two different IVI drivers from two very known instrument companies, Rodhe-Schwarz and Agilent Technologies.
I have to mention that both these companies releasead their IVI NI LabVIEW 7.1 drivers under NI Instrument Driver Network and ready to be installed and used by any customer of these two instruments.
The bug is present only in LabVIEW 7.1 version as if I take the same VI that breaks in LabVIEW 7.1 I could run it without any problem in LabVIEW 8.0 or LabVIEW 8.6 versions.
Anybody could test this bug for these two NI released IVI drivers in simulation in LabVIEW 7.1 by following these links below.
Agilent ag81150ni IVI Driver for LabVIEW 7.1 install from here. Run in simulation only by setting 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. Run in simulation only by setting Simulate=1
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E91D6659CE034080020E748...
After installation complete close LabVIEW 7.1 if was open, then restart LabVIEW 7.1 and now you may see under the LabVIEW Instrument Driver Palette two new IVI drivers ready to be used as LabVIEW 7.1 wrappers.
Open a new blank VI and from Instrument Driver Palette use two well known Vis that are Initialize With Options.vi and Close.vi add them on your blank VI block diagram and connect thm together. Accept all default parameters except Simulate that must be Simulate=1.
Both Vis run OK in simulation mode without errors. Now pick a Property Node from VISA Advanced Panel and squeeze this between the Initialize With Options VI and Close VI and make the instrument reference in-out and error in-out connections.
Now run these two simple Vis in simulation
I run Rodhe Schwarz IVI driver and Property Node passes OK until the end
I run Agilent IVI driver but Property Node is getting out Error Code 7 that is the same as my own driver error.
Both these IVI drivers are under NI Instrument Driver Networks and have been built and integrated as native NI IVI instrument drivers.
Question is why they behave so different with respect to Property Node from the VISA Advanced Panel?
I attached the screen shots as PNG files that show clearly the difference of VISA Property Node behaviour when used under the same circumstances.
Thanks  Sorin

Error -70038 occurred at Property Node in nimc.fb.power.power.coordinate.vi

HI,
I created a Real Time application with debugging enabled that only makes a straight line move and then finds center (using SoftMotion function blocks). When I run the VI from the project everything works fine. When I create the executable and run the application as a start up some times it moves beyond the limit switches and I have to abort the application, it never really works as smooth as it does when ran directly from the project.
I simplified the application. When connecting to the executable ( Operate>>Debug Application or Shared Library...)
I saw that sometimes I was getting an error that said the find center function could not be executed because the driver was not enabled. This was never needed when running from the project. I added the Power SoftMotion block and I enabled the driver before getting into the while loop that finds center. Again the VI ran without errors when ran directly from the project, but when I connected to the executable I found the following error coming out of the Power SoftMotion block (the name of my VI is: "Testing SEND to ZERO by itself.vi"):
"Error -70038 occurred at Property Node in nimc.fb.power.power.coordinate.vi --> Testing SEND to ZERO by itself.vi
Possible reason(s):
Motion: An unexpected error has occurred internal to the driver. Please contact National Instruments with the name of the function or VI that returned this error"
I am using cRIO 9022 as a controller and two 9512s.
LabVIEW 2009
NI-RIO 3.2.1
SoftMotion
Any idea why the VI works fine when ran directly from the project but does not work as expected when ran as a stand alone application directly on the cRIO?
Thanks,

Marc,
When I simplified my program, I forgot to put the Power Function block inside a loop and make sure I was sending a pulse for the execute input. I am guessing that could have caused the weird error.
If I see it again, I will let you know.
Thanks,

Some example vi of the sound and vibration toolset 3.1 use property nodes with an undefined class (e.g. svx_DAQmx Popup for DSA.vi). I use Labview 7.1 and NI-DAQmx. Could it be that the vi uses classes from traditional NI-DAQ?
