• Capture of waveform in the waveform diagram

  Hello

  I am trying to capture the waveform in the waveform table save it as an image.

  The reason why I'm not backup data is that we have a lot of test data and we do not want to draw hundreds of waveforms again manually.

  No one knows how to do?

  Thank you!

  Here's an easy way to save an image of the graph.

  

  You can save only the graph as BMP, EPS, EMF, or PICT with another method:

  

• Deleting the definition of Type casuses control a lot of misreferences and program in the block diagram errors

  In LabVIEW 2010, I have a Def Type control i.e. a Cluster with several other controls within the Cluster. Apparently, the references to the controls in the block diagram are based on the order that the controls have been added to the Type definition command. The side effect of this is that if a control is removed from the command of Type definition, many of the done Variable reference in the block diagram or now either broken, or worse still, refer to wrong control in the Type definition. These problems are quite difficult to find and fix.

  Comment: If you create a control of Type definition and make a Cluster. Now add any controls to the Cluster in an order, let's say A, B, C, D. Their types does not matter. Now use the Type definition in one or more controls on the front panel. In the block mark references to controls inside the Type Def would control on FP. Now return to the Type definition and remove the command B of the definition of Type. Now, lots of errors appear. Broken links. But worse still, you see old references to B that now refer to C and old references to C are now referring to the old references to D and D are removed altogether, etc..  This side effect is much more errors, broken links and misreferences than expected otherwise.

  How add and remove controls anywhere in a Cluster in a Type definition, at will, without creating a whole bunch of errors in program, broken links and misreferences for controls in the Type definition that have not changed?

  
  

• How to determine the strict reference to the table of waveform

  Hello

  I want to change the properties of a waveform by programming. I used to get all references maps of waveform a function of range in my script VI VI. Then I typecasted references to more specific class (strict-single track) after this trial I was able set properties such as data history. Everything works fine but if I add a graphic that is multiplot, that this approach does not work.

  The problem is that in the table of references, there is reference to a graph in multiplot waveform, and this reference is not possible typcast to the more specific category (strict-single parcel).

  My question is: how to determine if the reference in the table is matching the proper waveform (single or multiplot) charts.

  In the VI attached is a code that demonstrates my problem.

  Thanks a lot for the replies

  Jan

  Thank you for advice. VI point 2 from your answer, I created and it works. The solution is attached.

  If I understand it correctly. I need to know the type of chart to come.

  My first idea was to create a VI in Drop that initializes all the graphics of VI on chart type independently.

  But this solution is fine because I will only use graphics-single plot and multiplot(two elements).

  Thank you

• Reference of YC waveform monitor not updated with the reading of the monitor program

  I work through the Adobe Premiere Pro CS6 "Classroom in a book" (pitty me!) and got to the section on the YC waveform.

  That I consult the YC waveform graph in the reference monitor, in the book he notes...

  "When the Gang to program monitor button is selected [he is selected], the reference monitor moves in sync with the calendar and the program monitor.

  It isn't... I do something wrong or maybe my graphics card isn't it?

  Any suggestion would be appreciated with thanks - Lisa

  The waveform is not real-time.

  It updates when the timeline scrub.

• Node property/reference for the image and 'Create VI' inconsistent control?

  Hello

  I encountered this problem several times already and although I have worked around him, so far, I would really like to understand what is it:

  If I have an image display control on the Panel before (IMAQ Vision, not the image control type) and drag a property node or a reference to it on the block diagram, it seems impossible to create a Subvi diagram if the selected objects are equipped with a knot of property image or an image reference. Select 'Create Subvi' won't do anything, don period. No warning, no beep system, no nothing.

  A related issue is that if I have a view control reference on the diagram and try to create a control from it (for example to use as a control on one dimension of connector VI entry), same thing, "Create control" will not do anything.

  Why is this?

  Thanks for your comments.

  X.

  Xavier,

  This was reported to R & D (35835) for further investigations. A possible workaround is to make the Subvi LabVIEW 7.1 and open it in the new version of LabVIEW.

• Control of data using multiple thermocouples via indicators and the waveform in real-time

  I apologize in advance for this question is probably a bit simple but I'm all new to labview and the forum and could use some advice. I have a CompaqDAQ with two 9213 16 modules of track and I'm trying to read in 30 thermocouples in a waveform, but also display 30 indicators so I can mark each indicator with the thermocouple for real-time tracking. Each thermocouple corresponds to a specific location and it is essential that the interface has an accurate indication or a label for each of them. I wonder if there is an easy way to do this in addition to split the signal and have 30 thermometers on my diagram? Perhaps a table any? If I use a table to create 30 thermometers, the DAQ assistant automatically sorts the thermocouples according to ascending numerical order. For example, would be the indicators of first and second on my interface automatically assigned to channels a0 and a1 of the first module, or should I do it manually? Even for the waveform?  Thank you very much!

  PS - Do not know if this message had need of more details, but let me know if more information is needed, and I'll give you!

  I see that you use the DAQ Assistant to create your task.  Now I understand why you may have about labelling.  It is easy of the seller NOR spiel booting...  But in any case, you already have a task to the MAX instead of use the DAQ Assistant?  The interface is similar and there may be a step or two, but your end application will be more effective and you will have more options with your data and properties.  For example, I tried to update the names of physical channel in the DAQ Assistant installation program, that it let you do, but it propagates that change forward to waveform chart legend.  Also, I don't know any property for this dynamic data type node, although I never use it either.  I suggest the setting up of your task and channels, Max if you'd give it a go.

  Since I thought I didn't really takes you all the way with you help, I wrote another one.  It uses a cluster, even if it's a bit barbaric.  I thought that there was a more eloquent way to do by changing labels, but I could not it works as I had expected.

• What is the best way to keep the block diagram / cleaning of façade?

  Hello

  I'm relatively new to Labview so I'm not able to say if I'm overloading my programs or make my too crowded block diagram. I was wondering if there was some ways to tell if I can simplify my programming just by looking (perhaps only experience contributes to these things)?

  I enclose my VI here. Currently, she is able to monitor the voltage and current of two engines. On the screen, you can see an indicator with the voltage and current values and there are cards that can display signals of different engines with a menu drop-down.

  The façade is pretty clean, in my opinion of novice, but the block schema seems messy to me, just at the first glance. I foresee a problem occurring in the future however. In the future, I will have the VI to monitor 50 engines globally. All of the programming will be the same as the one I have now, but it will have 50 indicators and unfortunately 50 times just about everything. I would like to avoid this, but I don't know how I did.

  I use a USB-6009. I use its four differential inputs to monitor the voltage and current of the two engines. In the future, I will get more units DAQ (25 in total because 2 motors can be monitored for each data acquisition). The new Renault will help will help with more resource space, but I think things complicate with the added option of 24 more Assistants of data acquisition (as used in my code).

  Thanks for any help you might be able to provide!

  Usually, it is above all the experience that will teach you the best methods for making your code to do pretty. I don't know anyone who is proud of his first application of claws. There are some resources out there to help with best practices, as that group on ni.com, but you will learn most of your own development.

  Your façade is superb. FPs in general really are to you. You can do it as ugly or pretty as you want. When you have a few controls in duplicate and the Group of indicators, you should use clusters and berries to simplify. You can use a bit of cleanup in this regard, but not much. In addition, I personally hate read red text unless it is a warning any.

  Your block diagram could use a little cleaning in a sense of modularity. You have a lot of repeated code, which you might consolidate in to a Subvi, which is used in multiple locations, or in a loop For. A general rule is to keep your block diagram within a single monitor. You should not scroll. Your application is quite simple, so it is difficult to BUMBLE

  Here are a few details on your block diagram:

  • Click with the right button on your devices on the block diagram and uncheck the "display as icon". You are welcome.
  • Operations on each waveform "(x*2-4)" / 16 in double ": create a Subvi and/or run the waveforms through a loop."
  • You do a lot of 2-element arrays and then indexing. Just replace the ones that have a Select node based on digital.
  • All your code runs every time, including the knots of your property at the bottom, which is not necessary. As you learn LabVIEW architectures, you will learn how to get around this with the initialization and the output of code, but for now, you should put a case around those structure for only when the engine numbers change.
  • I don't know how you're timing your main loop, but you should put a delay in there because you don't need the DAQmx node shoot as fast as your CPU will allow.

  There are videos of intro free that you can watch to learn what OR think in terms of coding and teach you some of the basic features and such. Here's a three-hour course, and here's a six-hour course.

• Get the reference to the type of control of def

  Hi all

  I've been using VI script to update certain parts of the report and have encountered a problem in a case.  I was not able to get a reference to a def control (.ctl file).  The control is simple enum, and I recorded it as a def type because I use several places in my main VI, although I don't think that my problem has nothing to do with the fact that it is a def type.

  I know how to get a reference to a VI (Open VI reference function), and I know how to get a reference to a control in a VI (function Open VI of the reference of the object), but not a stand-alone control.  Details of the help file for the Open VI reference function imply that I might be able to do this with instructions to "Strictly typed VI reference", but it let me only select files .vi and not the .ctl file.  Please notify.

  Thank you very much

  You can open a typedef of control using the VI reference open and the path of control of wire on the way to the VI.  You can then change the control with scripts by obtaining a reference to the control on the front panel.  If you have a VI with control of typedef, you can get a reference to the typedef (not its instance) by obtaining a reference to the instance and using the Typedef VI or properties Typedef plotted for reference, or the path to the typedef.

  This can be confusing because a typedef is literally a VI without a diagram, and the script processes as such.

• Can't place separator reference in the private class data control

  Any reason, I can't drag and drop a splitter reference leave my block diagram to a private open class data control? Basically, I'm ignored when I let it go, even if I see an icon 'drop' after that I drag the control.

  Well, I think I got smart and just placed a generic control Refnum into the command group, and then used the VI of the server class to identify it as a separator. Interesting how I could drag and drop references to the sub-panels and other types but not a divider.

• How can I display only a part of the scale in the waveform graph

  This is the first time I try to use the waveform graph, since now, I used the table of waveform.
  The reason why I moved to the chart, it's that I need cursors.

  I have 2 problem

  the first: in the diagram, the graph moves when I add a new data and the scale of the x-axis stay the same size, in the right size I always saw the new data. How can I do that with waveform graph?

  Second: How do I say Labview to the day I click on the graph, I need that because when move graphic I lose the day, and to make I need to zoom out, I drag the imprecateurs.

  All this must be done programmatically. The LabVIEW graphic accepts tabular data, not only as the table and the graph doesn't have the ability to retain the previous points, like the story of a graph. You will need to retain previous values and then continually update the graph with the old and new values to get a shift register "chart as behavior. Cursors should be written programmatically re of each iteration, since you rewrite the entire graph.

• How generate the waveform analog multi simultaneously.

  I use the relay Full.vi Gen to generate a waveform.

  I want to create another form of wave and start at the same time.

  Any suggestion?

  Hi turbot.

  The easiest way to make the two tasks simultaneously is to have two copies of this task in the block diagram. In LabVIEW, any function that has all its entries ready or a Subvi runs "simultaneously", so no additional real action must be taken to make them simultaneously. However, you must make sure that all entries of all your screws are to be executed simultaneously are ready at the same time (which means a set of functions that generate the wave does not need any input on the other). It's called the data flow model in LabVIEW. Read this for more information: http://zone.ni.com/devzone/cda/tut/p/id/6098#toc0

  I would you suggest to use an other sub - VI for opening and reading your file (as well as use a different file for each reading Txt Subvi relay). You can also make your Subvi re-entrant. For more information on screw reentrant, refer to this link: http://digital.ni.com/public.nsf/allkb/98847B4E4C715E6D86256C59006B57CC

  I would also say that you pass the path to the main file of your VI by using a control in your Subvi, rather than using the constant you have now.
