Boolean switch node property in the Sub - VI

• Control disappear the node property for the post of Pentecost

  Why what happened? I accidentally create a situation like that in the VI and control disappear without any errors, can solve this problem, but the control never return to its original position.

  Hi Rodrigo,

  you are unable to find the control you went it off to the left...

  LabVIEW has some problems when the FP elements are moved by far (in a sense). These problems include not being able to find/move this element or results in an object with a width of 0.

  Why someone would move an item to > 16000 positions in both directions?

• Table & node property

  Hello

  I have a simple problem.

  On my side, I have a 2D chart.
  I can right click and exploitation of data > empty data to clear the table.

  I want to do this in my entry into force.

  If I do the node property or the local Variable with an empty array as input for my program initialization, it don 't work.
  They are therefore, any possibility of having a property node > data operation > empty table.

  In advance, thank you for your help

  Hey Mini,

  in your init framework you write empty tables to table three controls.

  When I test your VI it works as expected: all three paintings are deleted/erased...

  What else do you need?

  But as said before: you use two shift uninitialized registers. It would be really useful to initialize - using the same empty array constants!

• a node property to return the configuration of the task a DAQmx

  Tasks in this project are preconfigured in MAX, but once the operator needed to enter and change the sampling frequency, that I would like to add a routine to start to check the sampling rate of the configured tasks. I know that using a DAQmx property node can return task names and channel names, but what I could use is a property node to return the sampling frequency of the task. A knowledge of a way to do this?

  If you place a property on the block schema node, connect it to your task control. Right-click on the property node, and then select the DAQmx Timing (class select DAQmx-> DAQmx Timing). Then select the sample-Rate property > clock.

• disable the node property problem

  Hi all!

  I want to do a VI that the user will not fool around with the button.

  So I put in my case for the "change the value" event, a node property disable during 1 second (disable) and out of it, an enable.

  The problem is that if I press the as button 3 times in 1 second, the button will still change the value 3 times, as he has memory.

  I want to just the user to be able to make changes to the value only after 1 second and not save them. I hope I made myself understood

  Are there any suggestions?

  You may use a state machine with two loops. UI loop place the actionwith a timestamp and the loop of consumer can compare timestamps to decide if enough time has passed, or if the action should be discarded.

• all the nodes property objects and objects grouped

  Hello

  Now position an on my GUI objects in the center of the screen using nodes property. However, I don't want to have to have a node property for each decoration, image and control. Is it possible that I can group all the objects and then use a property node to position them? I tried to use the property node all objects, but none of the clues seem to apply to my group of objects.

  Help please!

  Thank you very much.

  John

  p.s. I downloaded my vi test. The graph, the decoration and the exit button have been grouped. control over check.vi to set the object to be moved.

  Tabbed pages are a great way to group objects GUI.

  Rather than use a decoration,

  • use a tab control
  • Delete everything except the first tab
  • Hide tab
  • The value of the proprties of the tab control and control on this page is move, hide, display as well as the tab control.

  I hope this helps,

• Connecting the node property programmatically to objects in front?

  When I right click on a property node, I see the option to connect to any object of front panel.

  Is it possible by programming? I create three charts XY and I want to know if I can control

  the color of terrain for all three charts XY with creating ONLY a property node (color graphics) and placing it inside a loop for

  and for each iteration of the loop for example, linking the property node to different XY graphs.

  See the image.

  Hello

  what you can do is to select the option 'disconnect control' when right clicking on the property node (it becomes a generic property node to pass a command reference XYGraph), place this property node in a loop for, before the loop, build an array containing references to your 3 XYGaphs (right click on each XYGraph > create > reference).

  Hope this helps

• How to detect the correct sequence of Boolean switches pushed

  Hello

  My program is all what I want too. However, I need to have the Boolean switches (digital inputs when wired to the equipment) be detected in the right sequence. There are 16 switches on a Board of material. The test subject is displayed 3 colors before hand and the sequence of buttons to push when prompted on the screen with one of the colors, each color pertains to a specific sequence of 4 switches pushed on 16 as quickly as possible. The sequence of buttons remains always the same according to the three colors red, yellow, blue.

  In the program, which is 99% working properly I tried to use a sequence of plate. It will give me a real if I hit the switches correctly - but will also give a real if I hit them back etc... I thought that a flat sequence is read from left to right?

  Then I messed around by using a structured event - the array of switches, pushed index and compare it to a table of values control. I understand how it works, but the correct code is elusive.

  I have attached a picture of program I did but it lacks the proper sequence. (Flat sequence)

  I have included the code for the structured event that I messed with. Don't laugh - I was just making experiences - I've never used a structured sequence before configuration.

  Hope someone can help me.

  Ned

  Hi Ned,.

  Your producer-consumer model is actually very close to work.  In the original version of screenshot, it seems you are trying to use the structure of sequence to capture the order, but in reality you will capture only the AND logical of all the 4 buttons with no information about the order in which they were pressed.  The structure of sequence does not by itself is waiting for an event to happen inside the frame, it which means that all 4 frames read as fast as the processor moves to their reading - which will be very fast.

  I've made a few changes to your VI and renamed him Rev 1.  See if it makes a little more sense with the notes I made on the front panel.  I also did a different version with a loop simple and some added functionality (-Ko), just in case Your ' e interested in another way to look at it.

• IM new to LabVIEW. Is it possible to send the signal to more than one parcel on a chart by using the value property of the graph node

  I'm new to LabVIEW. IAM trying to display two plots on a graph using the node property value charts. I tried to feed the two signals into a signal of fusion and then in the value property node, but it did not work. Then I tried to build a table of two signals and it powers the value of hardware node. It did not work. What escapes me, should I use the node property value this way?

  
  

• Node property of a control inside the cluster within a table

  I created a control that has a cluster to a Boolean, a string, and a digital.  Then, in my front, I created a table of these custom controls.  I wish I had access to the property of the controls inside the cluster in the table.  That is to say, I want to change the color of the Boolean or blinking, or "disable and gray" text box.  I think I'm on the right track, or maybe I'm on the wrong track.  I joined and example VI (testtray.vi) and control that I use (UUT_Display.ctl).  Please excuse the use of a flat Structure of the sequence, I know it is bad programming practices, but I just wanted to throw something together.

  Any help would be appreciated.

  Kevin

  Items in a table can have different values, BUT each element of the table share the same properties.

  "Blink" is a property when you make one in tha table blink you will all Flash.

  This restriction does not apply to clusters.

  So in theory, you could develop an XControl that has a data type is an array, but the display is actually a cluster that resembles a table. But write an XControl is not a trivial task.

• Nodes property and rings of Menu

  So I have this multimeter I need to make a driver for, and it has so many modes/scales of operation it will be a pain.

  

  So that's what I'm working with, there are a lot of 'functions of measure', including the tension continues, alternating voltage, current DC current alternative, etc, there is more than what is shown in this picture, but functions are the first row in the table above.

  Associated with each function is a set of ranges. GPIB codes for each range are on the left most column, and you can see what they are in the other columns.

  To manage the functions of measure and the beach in this driver I have, I'll use 3 sub.vis:

  The first sub.vi is very simple, consisting of a ring of unique menu, a number to string converter, then a concactenate string, shown in the first attachment. It sends the command of the unit function.

  The third sub.vi is also quite simple, it sends the range control to the device.  This is the sub.vi between the two that I need help.

  What I want is to have a single control of the range , in the form of a ring of menu, and the 2nd sub.vi reformatted this menu ring. So what I need is to use a property node to set the line items in the ring menu to match with items included in the 6 columns above, so that if the function is chosen to be volts DC, the menu range ring will show 3mV 10mV, 30mV, 100mV, etc etc, but if the function is chosen to be alternating current the menu range ring show 3uA, 30uA, 300uA, etc etc.

  The other tricky part of this is that the voltage and the current functions of the AC pass range controls (see how there is no range associated with orders R2, R4, R6, etc.).

  That I'll probably be able to come up with something clever to treat (as simply double the value coming out of the ring and incrementing it with a + 1 on these functions to make them all odd), but for now I need help in the form line items in the menu ring.

  Attachment 2 was my first attempt to simply edit the line items in the menu ring.  Unfortunately the way it is put in place, he crams this whole string them in 1st command line, rather than separate.  I don't know how to change one of the elements of the past that 1st menu ring.

  Hope I explained quite well, make me know if I need to be clearer.

  You use the wrong property.  The property to use is 'Strings' and the entry is an array of strings.

• Change the Sub.vi field

  I want to make a sub.vi to manage all of my property nodes that I use to customize my XY graph, and I have a general question about how I connect.

  Attached is a composite of 2 fired, the bottom is the expanded view of the sub.vi to change the route.

  In my main program (represented by half superior) my "Vibration response trace" is elsewhere in the .vi, within a state machine within a producer/consumer.  The .vi change parcel will be run before or after the plot has already been formed, not while he is in training.  (it is not placed inside the state machine with the real indicator of XY, but outside of it).

  I didn't know how to make nodes property to reference my field correctly when you use a sub.vi.  What I ended up doing was make a graph XY CONTROL in the sub.vi and wiring of a local variable in compatible reading at the entrance.  (I can not turn the main XY graph in the program in a control because I use the original indicator and a "build graph XY" to write about it.)

  I am concerned about 2 things:

  (1) if the nodes in my property will return the correct plot and change the background, plot color, etc. correctly in the main .vi

  (2) If using a local variable as long as such short risk to wipe the main XY graph to clean up data, i.e. If the local reads the chart before the data are there, but don't run the sub.vi until after data is collected, will it reset my chart when it crosses the sub.vi

  You must create a reference to the curve XY in the main VI.  Pass this reference to the Subvi and use it to access the properties and methods of the chart.  Everything you will ever in and out of the terminals as you do now is the value.

• Boolean front panel disconnected from the block diagram

  It is very strange behavior I've ever seen elsewhere.

  I opened a program that I have used before that works, after the replacement of some dll which is called.  I don't know if it's relevant, but just in case.

  In any case, I have a structure of the event in a loop.  Events are to turn certain values of output in a bitmap and update some of the entries.  As you can see in the screenshot of the time-out loop, the values of the input bitmap are fed directly in the Boolean flags.  The problem is that even if the thread is true, the façade is not up-to-date.  Also, when I click on the button stop, the Boolean value on the wire is not up-to-date.  You can see on the screenshot of the probe and the front panel.

  At no time have I stopped explicitly updates from the front panel.  Indeed, the status indicator updates correctly.  But he only makes a Subvi.  If you pass a reference to a front panel indicator in a Subvi, it locks the front for some reason any?  I thought for sure, I had done this several times in the past without problem.

  I'll post not rather the VI publicly without more deletions.  Just the stuff company owner.  I wouldn't mind sending them to someone OR, however.

  

  

  Thanks for any help.

  It was apparently a transient state.  I arrived, open LabVIEW and the VI, and everything is fine now.  I don't know what that looks like, I am back and found a few nodes property overwrite values.  I promise you that I will not change anything.  I should have tried this yesterday, but it was the end of my day at that time and I had a place to be.

  If you want, bradyAE, you can send me your email address and I'll send you the VI, if you think it is useful to investigate it.  Like I said before, I would rather not post it publicly.

• node property outputs false values

  I'm having a problem with output occasionally erroneous values for a control.  I move the mouse cursor around the screen, between 4 controls programmatically.  Most of the time it works fine.  Every now and then, the cursor will move to the wrong part of the screen.  I followed him there down to the property node connected to the refnum command.  I plugged the refnum indicators enter the property node and values that come out as seen in the block diagram:

  

  The subvi is called for each movement of the cursor.  Exit normals for controls are listed here:

  

  However, sometimes the wrong width is released:

  

  Sometimes the wrong position at the top of the page (this is the first position of the previously selected control):

  

  Sometimes the wrong height:

  

  Sometimes the different controls and several times, he displays the same values of bad - for example the width sore 1944 went out several times during the collection of these data.

  I have a fairly complex system - a DAQ system (with a wheel) connected over the network to my computer and a fairly complex level vi.  There is a Subvi Panel that opens to define configuration settings, using the wheel, events user to move the cursor on this sub - VI Panel.  If I try to simulate the encoder, to eliminate complexity, just to create a user event every second, I don't see the problem, so it seems that it is possible, it is linked to the complexity of the system...

  Any thoughts would be greatly appreciated!
