Business Structure Sub Label bug?

• Event structure vs business structure?

  I'm developing an application that can be fairly entered user based... a lot of command buttons Boolean to do different things.

  In the past, I was able to avoid the event structures "change value" and went instead with a while loop, stacked sequence and series of structures of the case. After, I decided that it was a terrible idea. This time, I intend to build an array from a Boolean, convert it to a number and feed it in to a unique business structure. This will give me the ability to add cases for different combinations of the Boolean being pressed.

  I guess the question is: what is the best way to do something like that?  Does have advantages over the other?

  Edit: I was not clear.  I would like to a comparison between the method of structure of event 'change of value', and just feeding into a table-> structure of the case.  I also fear that with the bool-> structure table affair I'll run problems where I find myself with too much control variable and the value of the resultant becomes ugly number very quickly. The application has several buttons... then, finally, save, load, several different configure configuration buttons etc.

  Thank you!

  Thank you.

  The VI has yet InfoCluster.ctl.

  If you don't bring anything in the cluster, you should always pass the cluster via.  You run the same question ' use default if Unwired "as before.  The presence of these "case bundleless" begs the question why you have these States because they do nothing.

• Suggestion to turn this into a business structure

  This is an excerpt from an existing code that we were committed to change/clean. I have to assume there is some way I can reduce this to have only a business, maybe with a not - or not - or structure. Or maybe I'm overthinking cela. Basically I confusion to keep me in the code relatively simple when thinking about Boolean values compared. Any help is appreciated.

  

  This seems to be just a NAND, pure and simple.

  I came with the truth table was:

• Child model LVOOP with class factory problem change out business structure

  I must do something wrong, but cannot escape.

  I'm trying to create a child object (see the bottom row of the class hierarchy) by using a case based on an enum variable structure.

  When I trace the code I have the 'ssh' Connection Type and it executes the appropriate case, and I can see that the SSH.lvclass has been created, but when it happens outside the Structure box case it suddenly is a SFTP.lvclass object. The real wire when I click on it in the diagram also shows as SFTP.lvclass wven if the VI it will is certainly the ultimate parent of UserInterface object - all.lvclass.

  I tried to remove the wire and put new but it always come back to SFTP.lvclass.

If I delete this thread then becomes an object of Portforwarding, then an object netConf and if I delete it finally becomes an object of ssh.

  I think you may be confusing the thread name (taken from the names on one of the constants) with the type of yarn (which will be the common parent of all the constants).  Rename your constants, as anything other than their class name, and you will see.

• the label bug

  Hello

  CVI 9.0 (and XP64 using a GUI generated by the GUI editor, a problem), occurs if the attribute ATTR_CTRL_MODE of a control is changed programmatically from VAL_HOT to VAL_INDICATOR. In the user interface, the control mode is set as HOT. The problem is that the position of the label is shifted to the left in mode INDICATOR. changing the value hot translates the (starting) position. This happens for the digital controls and ring (I have not tried others). Thus the offbeat label may overlap other controls.

  I can't say if it is specific to the CVI 9.0, as usually, I build my controls programmatically. This time, I used the GUI editor for a faster test version...

  Also, I found no opportunity to present such problems/bugs that this forum. Is this the right place?

  Wolfgang

  Hi Wolfgang,.

  It is perfectly acceptable to submit bug reports in this forum.

  Floating labels are associated with the bulk of a control in a way such that when the part master changes position, the label is automatically repositioned. You see, for example, when you move a control and label moves with him. What happens when you change a digital or ring indicative control is that the inc/dec arrows on the left of the control disappear, and the entrance area of the control (which is the main part of control) grows to the left to fill the empty space. This movement to the left of this part of the command results in a label which is on the left side of the control (as opposed to, say, the top of the control) to also shift to the left in order to maintain the same distance from the main part. By the way. This does not happen only when you change the mode of control programmatically. You can also see if edit you in the editor.

  The solution for this is to save the position of the label (ATTR_LABEL_LEFT) before changing the control mode and then set it to the same position, after having changed the command mode.

  I agree entirely that there is a scenario in which most people would probably not consider the label to move, since the control as a whole is not really 'growing up '. But because the association between the label and a specific part of the control, and because this part is increasing, so this behavior occurs as a result.

  Because this behavior has always existed, even if we considered undesirable, that we couldn't really change at this stage, from now on, it is very likely that there are programs that have come to rely on it and change the behavior would break backwards compatibility.

• PROGRAM SLOWS DOWN WHEN IT ENTERS A BUSINESS STRUCTURE

  OK, so here is the problem I have do this output pid controller is between 0-100 in this program, I'm just trying to make it work so I made a function to compare that when the controller output is 0 and the constant 0 I'm starting a business loop which transform the output for a second and turn off for a second.   When I go into the structure of the case, the rest of my program slows down

  I don't know why, I tried to do a while loop and a structure outside my main loop but I can't get my signal of my statement to compare to enter the second loop where I get my output to bike in 1 second intervals

  This is the VI please help

  I'm still learning how to use labview in passing

  Thank you

  Gary

  Gary,

  The next thing you want to learn more about LabVIEW dataflow. This is the fundamental paradigm of LV and explain your slowdown problems.

  The basic concept of data flow is any node (node = function, Subvi, structure) can begin to run when the data is present on all its entries and no data will be present at its outputs to execution comopletes of knot.

  How will this affect your VI? The real deal has a wait 1000 ms (actually two, one in each case of the internal structure of the housing = redundant code). The structure of the case will not complete execution until the wait ends. And the while loop does not complete its repetition until the end of the structure of the case. The result: at the exit of the PID.vi = 0, the loop runs at 1 second per iteration.

  What is the solution? Continue execution of the loop at intervals of 100 ms. sure in the structure of matter (true case) and another register to shift of how number of intervals of 100 ms is passed. When the count reaches ten, toggle the output line.  Do not use the 1000 ms of waiting.

  All the code in your internal structure is not necessary. Connect the output remains directly to the digital Arduino write VI.

  Be careful with the comparison to zero with floating point data. If the calculation which produces data has round off errors you could get a value such as 0.573E - 15, but which is not equal to zero. It is better to compare to a small range of values above and below zero.

  Right to left wiring is much easier to follow in trying to understand what makes a program. Using the tool to clean occasionally will help (although he eventually frustrate you also).

• How can I get a business structure group?

  I try to place a Boolean indicator in a structure of housing through LabVIEW scripting and am not having any luck.

  I started with the source code following, which creates and populates a case of a table structure:

  https://decibel.NI.com/content/docs/doc-22703

  So my code, rather than an enum inside each case, creates an arithmetic composed and a mask for each case.  It's that everything works fine.  I now want to place some Boolean flags on the Panel before which correspond to each case, and that is my problem.  I can create indicators, but when I look at the display of block diagram, all the indicators are located outside the structure of the case, rather than indicators are inside each respective case.

  I think that the reason is that a Boolean indicator is created by passing a reference to the façade.  But the problem is that the reference of the VI Panel does not indicate the Boolean value should be placed inside the case, just on the Panel structure, so when you view mode block diagram, he just threw the indicators structuring everything outside the case and wired their place via the tunnels.  I get the reference panel by accessing the my CaseSel object OwningVI field.  I feel that there must be some field case that I should be able to access which indicates that it takes to put the boolean schema inside the structure concerned case, but I can't.

  I've attached a file with 3 photos in there.  We show a picture of the code that I use to create indicators.  Watch the output type I'm looking for.  A watch the type of output that I get.

  Before connecting the wire to the Terminal, call the Move method on the terminal of the indicator and use one of the [] of diagrams of the structure of the case as the owner. This will move the Terminal in the structure.

• How to use a signal of true/false dynamics with a business structure?

  Hey everybody-

  Is it possible to enter a case structure dynamic data of true/false?  We try to generate a waveform and want our structure case to run when the wave exceeds a certain threshold value and freeze execution when it drops below the threshold (If false).  However, we want the case structure to run continuous - i.e. If the structure of the deal for the 'real' case running while the waveform is above the threshold, we next want to deal for 'false' structure to run when the wave goes below the threshold, and so on until we stop our program.

  Any suggestions would be much appreciated!

  Remove the loop around your DAQ Assistant vi express (I hate express screws).  There is already a big loop around all of the code in the lower part.  As has been pointed out by Ravens Fan, don't assign continuous acquisition.  Set a finite number of acquisitions.  Then the rest of the code can run and the loop can travel again.

  Get rid of the stop sign at the top.  When the code is finished, Labview will stop on its own.

  You have two stop buttons.  Only one is necessary.  Look at my example posted a few messages back.  A STOP with local variables.

  Shrink your block diagram.  It takes more than one monitor space.  It is difficult to read when you have to scroll all over the place.

• Business Structure - case specific error

  I'm in my case Structure (T/F) with a line simple mistake... but when I leave the Structure of the case, I want to go the direction that the case sends me.  For example, if my case is true, I want my merry way, luggage in hand until the error line just straight crossbar.  For the fake, I want to go a different direction... can I add a second Tunnel of line outgoing error?

  

  I recommend to meditate on the mental health of your ideas. Do you really need two outputs error for the structure of the case?

  In any case, there are many solutions:

  • You could brach wire of the error on the two tunnels to exit for cases that have only one source of error.
  • You can use the tunnels 'use default if the thread continues'.
  • You can use "merge errors" to combine several threads into a single error.
  • etc etc.

  It is difficult to say much more without seeing the rest of the code? What is in other cases? How do you guarantee that the while loop will not forever?

• Business Structure - timer / controlled waveform

  Hello world

  I am building a waveform of controlled time/switch. I have three different parts of waveform to 8192 samples each. I have a case of Structure inside the While loop.

  Structure of the case must have the following properties:

  -1st line (from above) on the output until what you press Start. This is the first part of waveform (normal state of the signal) so I can write these data several times.

  -When you press Start, the current examples are written after that write data of 2nd line exactly once (it's a transitional part of waveform)

  -end of the transient wave, write the fixed part of the signal (3rd line)

  - and finally, return to the 1st line of entry.

  Switch box must be done after prior data wrote because I need to synchronize the start of a signal which ends on the other.

  Any help would be greatly appreciated.

  Thomas,

  I did something like this before.  I've handled by putting the waveforme write and play in a loop (with a case defining structure that array to write to the data acquisition card).  In this way, if there is no action from the user, a default waveform is always written on the card and played.  When the user presses a button, a Boolean value has triggered another round of case (you will use the Boolean value to trigger a simple state machine that determines what table to write).  The final value of the state machine to go back to your original state.

  Example:

  State 00: Normal default waveform running

  State 01: User Action to start-> tracks 'line 2'-> change boolean to go to State 10

  State 10: series 'line 3'-> change to 00 status boolean

  State 11: {unused condition}

  The only part that this should affect is the writing of the real array to the data acquisition card (i.e. keep the rest of the code out of the apparatus of State, but within the main loop)

  I hope this helps,

• 'secret order' to avoid typing all cases in a business structure to manage a real table

  The question is simple. I don't know if there is a command (similar to "..") to represent a group of a real table in a structure of 'case '.

• Can I paste code directly into a business structure?

  Hi all.  I use Labview 8.6.1 and I have a small question.  I'm trying to copy a piece of "code" of an old diagram in a new.

  It works fine if I just stick in an empty space.  But if I try to paste it directly into a box structure, I lose all the wires and the code seems to rest on the top of the structure of the case rather than getting included in it.

  One solution is to paste this old code into the empty space, and then drag to the structure of the case.  It works very well.  But is it possible to paste the code directly in the structure of the case?

  Thank you.

  For some reason when you try to paste directly into a case structure, code is floating, I think there is a reason for this, probably to do with the tunnels of the structure.  I usually stick like a floating code on the case structure and then make her slichtly is not floating.  The new snippletts code can work around this problem, but it is not available in LV2009 only 8.6

• structure business with interval value

  Hello crew NOR! I have to set a case structure for many cases. But the problem is that cases are not enabled with concrete values, but with intervals, for example:

  in 'A' variable that can have multiple values (including decimals):

  1<= "a"=""> <= 2=""  =""  =""  ="" -="">case 1

  2< "a"=""> <= 3        ="" -="">case 2

  3<"A"> <= 4         ="" -="">case 3

  So, is there a simple way to do this with a business structure?

  Thanks in advance!

  Hello :-)

  If you use a numeric value to trigger the struvture of all you need to do is type 3.15 in the switch case label (note the two period characters) and it will call this case for any value in the range of 3 to 15.

  

  Happy coding!

• structure changing case label

  I have a structure case I want to change the name to and remove a.  I did it on the case structure pane and the new name became red.  This is probably due to the enum connected to the switch case has still all old enum labels.

  I tried to change the enum, but it does not allow me to change the name of the enum and will not remove the case structure that I deleted.

  How can I get the enum that is connected to the switch case structure to match the business structures?

  I thought about it, I changed the type definition and changes took.

  Sorry to waste your time.
