Change the text displayed, based on the threshold value

Hi users of Labview,.

I need help with display and editing text in labview.

The text should display and change according to the following conditions:

0 volt - "no power".

1 volt - "controller ON".

2 Volt - "Rotor Running"

3 volt - "Rotor stopped".

Based on the voltage read by the channel, the text must be displayed and modified on the same area of the front panel. For example, initially it will be 0 Volt and the text "No power" should appear as an indicator of text (and not as a warning message). He needs to change ' controller we ' when the chages of voltage from 0 to 1 volt. The canal reads the analog input voltage (range 0 - 5V).

I'm relatively new to labview. So please give me pointers or from suggestions on how can be done. Any help is greatly appreciated.

Thank you

Hello

Thanks for the crossrulz of notes, have not used the front threshold.  For this simple example, it is "symmetrical", but I can see how the values in the table have been does not correspond to the index position that is so true useful.  Learn something every day, I could not resist, wanted to try.

OK, here's a sample VI that puts a custom message based on the crossing of a threshold.  Home work is to study the components before asking to :-)

The dice are the analog signal of 0 to 6.   He rounded to the whole number to provide the index number.  Power is the index number in the index table, the table being hard-coded text messages.

Two additional indicators may be deleted, useful to see what is happening.

And get rid of the value 0 if you want the text to match the number, he he he

Enjoy.

  • Change the default value for new messages of the 'paragraph' in "text" format the answer currently online because it does not work

    The answer currently online for this problem said to follow the sequence "tools-options-composition" and then change the default value, but this sequence "tools-options-composition" does not exist in Thunderbird (at least in the version I have, 45.4.0). Under 'tools', there is no option 'options... '

    It can depend on what menu you look and which operating system you are using.

    Tools | Options | Composition refers to the menu bar on top old.

    You can use alt or F10 to make the menu appear temporarily. Go to the view of . Toolbars and check the boxes if you want it constantly on the show.

    If you use the button 'Menu of the Application' new fashion (with three horizontal lines - see the attached picture) then it's probably Options | Options | Composition -I say 'probably' because I'm on Linux where 'Options' are replaced, I think that, by "Preferences". Another complication with this infernal Application Menu is that different things happen depending on whether you click or hover. Place the cursor on the Options of the first and the second appears after some time.

  • How to change the default value of a parameter and LOV attached to a parameter

    Hi all

    I'm new to the discoverer reports and I need the following tasks:
    1. the need to change the SQL of a discoverer report
    2. need to change the default value of the parameter (from constant for the current month). In the discoverer more responsibility when I open the report and go to tools > > setting > > edit
    I can see the value of the default constant is given. On the right side there is a drop down that says "Value". I suppose that if I put a SQL as default, I need to change the drop-down list for sql or something and then put the code SQL. Problem is the menu drop-down is froezen and I can't change it.
    Even if I try to create a new report parameter.
    3 need to change the LOV associated with the element on which is based the setting.


    I have the discoverer more responsibility to myself and did not have the discoverer administrator (as forms 6i developer desktop tool) tool. My questions are:
    1. can I modify the SQL query using discoverer and responsibility or do I discoverer Administrator tool?
    2. any help on how to get the default value of an SQL query? Currently, it is a constant value.
    3. is there a way to understand is that the LOV is made of the constant values fixed (as a set of values independednt) or they are read in a SQL (value valid table sets)?

    Solutions pointers will be greatly appreciated!
    Thanks in advance.

  • You can change the default values for shape layers?

    Specifically, I want the default paths Trim "connect multiple traces' '' individually '' and default STROKE line Cap and line join defined respectively on"Round cap"and"join Round '.

    I know that I can copy and paste these properties also but I wonder on changing the default settings - perhaps in a preferences file? Thank you

    No, there is no way to change the default values. If you have a set of properties that you always want to use, you can save them as a preset.

  • You cannot change the chart value axis when there are several types of graphics in a single diagram

    Illustrator can do graphics with bars and lines / columns, for example in the docs:

    http://help.adobe.com/en_US/illustrator/cs/using/images/gr_15.png

    http://help.Adobe.com/en_US/Illustrator/CS/using/WS3f28b00cc50711d9fc86fa8133b3ce158e-8000 .html

    However, when I create a chart like this, I seem to lose the ability to manually set the y-axis using 'override calculated values.

    To reproduce this problem:

    1. Create a chart as in the example, with bars and an axis on the left, lines and an axis on the right. Unlike the example, don't fix the numbers as well as the lines align perfectly - have a go until just less than 20, a up to a little less than 250, therefore it do not markers and the number of divisions on each side.
    2. Try to make the markers and numbers of divisions to the height, so in fact, the side that is going up 20 going up to 25 and has the same number of divisions on the other side.

    Everything I have tried does not work:

    • If I select the entire chart and go to the "Chart Type", I can not set the options for the value axis. In earlier versions, it's gray, in CS6 I can access, but clicking on 'OK' does nothing.
    • If I select the entire chart and chose the type of a chart, I can set options for the axis value, but that the selected chart type, and then applies the entire table.
    • If I use the direct Selection tool to select one of the series and open the "Chart Type" options, changing the options of the y-axis has no effect
    • If I use the direct Selection tool to select all series that share an axis and open the "Chart Type" options, changing the options of the y-axis always has no effect
    • If I use the direct Selection tool to select the Group of ticks axis itself, or the axis line and groups of ticks axis themselves, of axis labels, axis and graduations of the axis line, or axis labels, axis line, graduations of the axis and series of related data, etc., by changing the options of the axis also has no effect

    It seems that this feature is broken and it seems that the example in the manual has been carefully chosen to use a rare combination of numbers where it would actually look right.

    I thought about it. Like everything to do with the horrible ancient neglected graphic Illustrator tool, it is ridiculously clumsy and involves the caution around what is shamefully bad programming for a professional expensive product.

    It is timing - to do things in a sequence of rigid counterintuitive that seems not to work then meets at the end:

    1. Create the chart but, for now, keep all the same chart type. If you've already set to have different graphics types, put the same thing for now.
    2. Select the entire chart and in the main window of Chart Types, set the value to "Both sides" axis
    3. In the drop-down menu, there should be a left and right axis (or top and bottom...). Set the parameters of the value axis for these now. It will look like it does for a single axis, because it will not change the other axis - naked with her...
    4. Select the data series you want to use the other axis using group selection. Go to graph Type and the value of the y-axis to the other and set the chart type that you want. All of a sudden all be put in place.
    5. If you need to change the settings for the value axis, select the entire chart, set the whole chart type to a chart, change the appropriate value axis by choosing it from the menu drop down and the re - apply types of graph as above.

    (the bug is - it should not necessary to set the graphic object to only have only one chart of type in order to access the axis options of value for two different y-axis)

    Why forced temp_num2 has not changed with the NULL value? I'm under 11.g rel2

    Best regards
    Valerie

    You can NOT change the column constraint NULL to contain NULL values by:

    alter table table_name modify column_name null; 
    

    After this change, the column can contain null values. In Oracle, not null constraints are created automatically when not null is specified for a column. Similarly, they are deleted automatically when the column is changed to allow NULL values.

  • Do not change the CMYK values

    So here is the problem,

    I have a document in Illustrator CS5 with a black background and there is a form of feathers in this document with the same color recipe. When you print you can see the object to feathers and it is clearly a different shade of black, although levels CMYK are the same. So I tried to change the levels of all blacks to just K = 100, and when I deselect, then reselect the object they just go back to the previous CMYK values. I tried several times to change the CMYK values with several black recipes by typing in the color selector box, but he always comes back to the original recipe. It will change if I red or something completely different, but not if it's still a recipe for black. Is there something that I am missing?

    Why can't I change my recipe for black?

    Why my document print two different shades of black when it's the same CMYK values?

    Should I have a corrupted file? Or is it a setting I don't know who is making this happen?

    If you copy it to a new file, CMYK (!), still doing it?

    Even if you can not post a screenshot, you could post screenshots of the appearance palette or the palette of layers, for example, so that we can not see the logo itself, but its structure
