• Graphic property node indicator position

  Hello! I have several graphic indicators and I want them to appear on certain positions, so I created property nodes where I define their exact position. I have a tab control in my design to separate the 2 pages front and the problem is that indicators are displayed on both pages. I want them to appear only on one page, how do I solve this problem?

  Thank you for your time.

  Hi cocopa.

  On the front panel, if you drag the graphical indicator in the appropriate page then it should stay there. If the graphical indicator has a shadow, it is on the top of the tab rather than inside a page control. In the block diagram, you must have a business controlled by the tab control structure. When you want to adjust the graphic position, have the indicator and the property node in the box to the right page. That should allow you to move the chart inside your tab control page.

  Kind regards

• Delete the graphic signals - no historic property node

  How can I erase the waveform graph since there is no property node history available for this type of wave form that I can see to set. The waveform has one table, but not the chart. Not sure why it is not the crux of the story, but I don't know there's a way to delete it. Any ideas?

  Use the value property of the graphics node waveforms. He lead an empty array.

  Hey presto, graph clears...

• 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?

  Greetings zapfle

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

• The XY graph Plot.LineWidth Property node problem

  Hello!

  I have a loop, where I repeatedly putting curves in a XY Chart. In the first iteration of the loop, after the first corner appears on the graph (I send data from the graphical indicator), I use a Plot.LineWidth Property node to align the thicker. However, in the next iteration, when the second plotted curve appears on the graph, and the property node is pulled again, the second curve remains thin. I guess what I've done wrong, that this property node defines only the first curve? How can I set the width of the line of all the curves of the XY graph on the same value? When I directly on the properties of XY graph, I can set the width of the curve, but only one by one...

  Suggestions how set the widths of the ground on a specific chart XY?

  Thank you!

  If it is a multiplot XY, you must set each plots properties by using the property activeplot (index of the new lot), then by setting the thickness.

• 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.

• 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]

  
  

• Sample quantity sample DAQmx channel property Node substitute in LabVIEW when = 1

  [cross posted from LAVA] 

  Problem:
  LabVIEW seems to be the substitution of a value of 1 to a value of 2 for the node property DAQmx Sample Quantity.Sample per channel for a continuous acquisition mode.

  Information:
  I have a task created in MAX (version 4.4.0f1).
  When I updated To Read samples 1 the task runs successfully in MAX.
  When I read the task in LabVIEW (8.5), the property node Sample Quantity.Sample per channel (i.e. the samples to read) is converted to a value of 2.
  If the value is greater or equal to 2 to the MAX, then the Sample Quantity.Sample by channel in LabVIEW property node returns the correct value.

  I get the same problem with a real or simulated device.

  Question:
  Is this desired behavior?

  Side note:
  If N samples (acquisition of buffer finish) is selected samples To Read cannot be 1 because it causes an error 200077 - must greater than or equal to 2.
  But no error will occur when the task is saved as a continuous (continuous buffer acquisition). I don't know if this is related. The error generated is:
  Error-200077 occurred to the DAQ Assistant
  Possible reasons:
  Measurements: Requested value is not supported for this property value.
  Property: SampQuant.SampPerChan
  You asked: 1
  Valid values begin with: 2
  Valid values ending with: 8589934590

  Shouldn't
  

  Hi JG,. Remember that the number of samples (one associated with DAQmx sync settings) is not relevant for continuous acquisition.  To read a sample at the same time, you simply specify this in your DAQmx playback function.  When you configure MAX to read an excerpt, it makes this same functionality automatically. You will not be able to get the value of another property node as the value is converted as soon as the channel is created (the value non-sous the constraint is not stored anywhere by the driver).  It should not be a need to this value in your code, if you want to read a sample to a schedule the DAQmx read simple example of function.  The amount of samples by reading is not part of the task itself, but is defined when running as an input to the function read DAQmx. You get the error message indicates that your device supports should not single-point HW timed - I would have probably asking which device you were using.

• Bytes to Port property node. When to use and when not?

  Hi all

  Ive frequently used bytes to port property node performing bed series and have not experienced any problems.  I've heard mixed on this subject reviews and I would like to know when to use and when not to use it.

  Thanks for any input.

  I will start by when it should not be used.

  When there are (as readable) ASCII data to come through and it is separated by a termination character.  Select the stop character and read more bytes than you ever expect a given message.

  When there are binary data, but a protocol where you know clearly how the message package is put in place.  In this case, you want to disable the stop character because any octet can be given legitimate and be interpreted as the stop character.  With these protocols, if you know the message is always X bytes, read X bytes.  If the message is of variable length, but the Protocol is set to tell you low for a long time the message is, and then make partial readings.  So if each message starts with 2 bytes that says follow X bytes.  Then read 2 bytes, which converted to a number, then read this number of bytes.

  When to use:

  The only time will really use bytes to the port is if you use a terminal of the installation type.  Just enter and display on-screen what never happens happened at the port since the last time it was read.  When you don't care where are message breaks.

  If you use bytes to the port and care message breaks, then you're obligated to all your new message concatenated to a string, you store in a shift register and each reading analysis through data to determine if you have a complete message and valid.  If you do not, do nothing and go back and read more.  In fact, you will need to run through the chain of data several times in a row before coming back to reread in the case where the message ever resulted in a single reading packets.

  The vast majority of applications falls into one of the above situations.  The last situation is not as common, and if you use bytes to the port with a system of e-mail that has defined a defined protocol or packages, you do a job more in programming to maintain a software buffer of data as well as the hardware buffer to the serial port.

• Local property node on the VI Analyzer VS variable

  Hi I'm preparing my review of CLD. I had this problem...

  I learned that there are two methods to update the icon on front panel using the value of the variable local node and property

  It is not a good method to update an indicator using these, but if we want to update a control, then there is no choice...

  CLD NOR recommend using the property instead of the local variable node, but when I run my code on the VI Analyzer he created an event

  believing that it is better to use a local variable for good performance...

  ???????

  Yes, the text is correct. Property nodes are useful to access things like visibility and string [] in the control of the ring, but for the value, it is much slower than a local variable.

  One of the advantages is that there wired error so you can force the data stream, and given that the nodes property are executed in order, you can use a property expanded node to find out what order things occur, especially compared to a free local and free property node, in which case you would be forced to use a sequence structure where ofc is a bad solution.

• 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.

  as follows:
