• 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!

  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)

• Property node (arg 1) visa set up a Serial Port (Instr) .vi-> Untitled 1. VI

  Hello

  I'm trying to connect an instrument stahl ER-300 with labview. The Stahl is connected to my laptop via a serial port/USB converter.

  When I run the program, I get this error property node (arg 1) visa set up a Serial Port (Instr) .vi-> Untitled 1. VI

  the driver of the converter is set up and my phone is read as a COM4 and I Don t understand why I get this error.

  The program is attached.

  I need your help

  The error indicates that an input parameter is not valid to configure serial port VI... have you checked that you had wired up to this node correctly?

  It is not wired! Thread resource name VISA through the VI.

• error of node (arg 1) .vi property VISA set up a Serial Port (Instr)

  Hi all

  I have a request, he had run on a machine well for months.  I use VISA to make the communication between PC and PIC.

  Suddenly at certain times, it reports error of node (arg 1) VISA property set up a Serial Port (Instr) .vi. Since then, it does not work.

  Œuvres of HyperTerminal.  I check MAX, the COM port it and looks very good.  What is the problem?

  Furthermore, I use VISA 4.2.  Maybe somehow it crashed?

  Many thanks for any help.

  Problem solved.

  The reason is that the hard disk was running out of space and there is error.  Somehow, causing accident DURATION VISA.

  We cleaned drive C: for free space and then repaired DURATION VISA.  Now, he runs with happiness.

  Thank you, everyone, for your help.

  

• Time GPS, Position, Velocity.vi - error-1073807360 reading was held at node (arg 1) .vi property VISA set up a Serial Port (Instr)

  We receive information such as the Latitude and Longitude of a receiver Garmin GPS18xLVC via a serial port on our PC using LabView 7.1.  Successfully, I connected the GPS on the serial port and tested with HyperTerminal.  I tried reading GPS time, Position, Velocity.vi several times and still receive the following error message: error 1073807360 has occurred to the property node (arg 1) visa configure a Serial Port (Instr) .vi.  I think it has something to with the configuration of the VISA series under vi.  Any suggestions would be greatly appreciated.

  Thank you

  I understood the question, that I had with the time reading the GPS, the Position, the Velocity.vi.  The vi. "do not open" port com automatically and so I had to modify the NMEA GPS Subvi reading to first open the port (VISA open command) and then continue with other operations.  Once I did this it started to work very well.  I don't understand why this feature has been left out because it won't work without it.  I tested the code with a receiver Garmin 18xlvc and it seems to work fine.

• Display the property Node error 1077

  I created a vi with several analog inputs (up to 20), and I want to be able to turn on and off on the front panel plots. I currently have this case structure configured to go through each entry (i n), and the front (LED buttons) can be activated and deactivated to choose which plot to display:

  

  Turn work, the plots but I get this error message:

  1077 error has occurred to the property node (arg 1) in NetworkAnalyzer_UpdatedDAQmx.vi

  Possible reasons:

  LabVIEW: Value of property not valid.

  Property name: field Active

  All solutions? Thank you.

  Are you sure that the number of elements in the array of Boolean is the number of locations that you did? This error indicates that you have more items that you have drawn in your array of Boolean.

• The property node reference

  Hello guys,.

  Using the property node, I confused with the terminal of reference there. Can we establish a special reference to the control (button, for example), but obviouly I couldn't connect the button directly to the point of reference. I find an example about which attached in attachment. How can I creat something like that? So enjoy!

  Phyyu,

  VI server references follow the structure of object-oriented class. A VI server reference can refer to a wide range of objects, such as a control, etc. variable indicator, VI. Server of VI References can be as strict or not strictly typed as you wish. A control/light specifically made reference refers to a command that you pass to it. You can request to be more rigorous by right clicking on the reference, and using menus to select the class that you want to reference. A tree of possible class might look like this: Server VI > generic > G object > control > Array. Now this reference requires a pointer to a table control and will not accept any other type of control. If you use this reference control to create a property node, the properties will be specific to the array class.

  A refnum is simply a numeric value that refers to a place in memory. Reference and refnum are used somewhat interchangeably in LabVIEW.

  I hope that answers your questions! See the help files of LabVIEW for VI server references to learn more about them.

  Kind regards

• How can I control the elements in the graphic palette (profile line) via the property node?

  Hello everyone,

  Is it possible to control the elements (graphic palette in the profile of the line) via the property node?

  In general, you must balance only Min/max property, then you can "zoom and Pan" by program:

• graph of waveform of filling via the property node

  Hello

  I want to fill a graphic waveform spirit multiple waveforms by programming. This means, the graph is the main VI, and use it in an another vi reference chart. Firstly I have to solve the correct reference waveform curve, then I use the "Value" property node The value must be the value of type variant, should be no problem. But the property node works only with table 1 d and not 2D.

  How can I fill it with table 2D programmatically? I use LabView 8.6, see attached example.

  Mitulatbati

  Hi mitulabati,

  You must specify the data type that you will be feeding to your chart, the default type is an array of 1 D.

  To do this, connect an empty 2D array directly on the graph, it will change the input to your waveform parameters and now the property node will accept this new data type.

  Hope this helps

• position in the property node is not updated in another while loop

  Hello

  I have a structure of the event in a while loop and I have a chart with 2 sliders on it. the chart is in the loop outside the structure of the event and it becomes a wave form when an event occurs.

  in a separate loop, I have 2 cursors cursor position property. I subtracted to get their distance. but when I move the sliders on the chart which is in the first, while the loop doesnot change the values given by the property nodes in the second loop

  is this something related to the structure of the event? don't needs real graphic to be updated all the time or is it ok if she becomes a waveform only on an event

  can someone please help

  Thanks in advance...

  The value of the variable "Stop 2"is in memory still "True" so on that a second (and resulting) running that your upper loop always ends after the first run.

  The display of "stop 2' LED is to be reset when you press the button"Get the waveform". making the False value.

  So reset the variable button after finishing two loops or before starting the two while loops.

• 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

  I should probably have joined the last post of VI, but I have has been a thread of error between the two loops.  I also deleted the text you had so I could see the I need to press the button.

• Line break in the name of the Enum element? (no further questions on the property node)

  I don't know what is the meaning to allow element enum with line feeds them names (\n):

  

  It is easy to do by directly editing the control over the public Service or a constant on the comic, but it's somehow not if you use the context menu 'modify Items... "who jumps to the top of the Properties window.

  As a subsidiary question, if I try to do it programmatically:

  

  It fails with this error:

  which simply means

  That's the script as an indication only (never used script before)? If I disable the "Show script methods, etc." option, it is still available though...

  This type of property node is useful if you use LabVIEW to write LabVIEW.  The main example of this is the DAQ Assistant, but things like the right frame click JKI also do.  You usually encounter when writing automation tools development.  For example, this particular node would be useful in a tool that converts a task manager based on a string to an enum-based task manager.

  You can find the full properties of each property and method using LabVIEW.  This includes whether or not it will work in the execution or change environments.  The enum is an interesting case that confuses many.  Modification of strings of the enum of the code changes.  Most people who want to change the strings of the enum runtime should use a ring or a listbox, instead, since you can change their strings at run time.

• 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]

  
  

• How to set the property node maximum xscale for several scale XY Chart

  Hello

  I use a graph XY with three X axis and three scales of axis Y to draw the three sets of data. This works well.

  What I do now is to set the Xscale.Maximum property node for one of the x-axis (the other two autoscale). If I click right in the (Create Blockdiagram; Node property; X scale; Maximum) I can not choose what x-axis I want to put the Maximum for.

  So my question: how to select a specific axis allows you to set the XScale.Maximum property node when having several axes?

  Thank you for your help, any suggestions are appreciated!

  Hello

  After some more research and experimentation, I found that using the scale property X Active I can determine/set for which the XScale.Maximum Xscale is used.

  This solved my problem.

  I hope someone else can save themselves a few hours with this thread!

  Thank you

• Unable to modify the property in the property node

  I am configuring a DAQmx routine where I record multiple analog channels. I am able to create the routine, but I read that there are some problems with multi-channel sampling (ghosting), so I wanted to avoid this.

  How to eliminate ghosting of my measurements? :

  However, when I try to use a property DAQmx Timing node, I am not able to change the property (see screenshot). I tried right click and left click and clicking on everywhere. I think that there is something I could not understand, but pointers would help a lot! Chaning between read/write does not help
