how to use delay using boolean inputs

[kavharshre]

dear sir

 I have created a AND logic where when both inputs are high using boolean switches output  should become high  green led should glow after 5seconds and other than it output should be false red led will glow. basically I want to use delay function .I am attaching file

thanking you

Hi, kavharshre:

You would be doing yourself a great favor if you checked out this tutorial, paying particular attention to the section on dataflow.  You would then understand why your code isn't working as planned.  🙂

Sir I have been able to solve the boolean problem

Now I have a query about the progress bar.I am new to labview 10.I have used the progress bar for extension and to retract.

I have been successful to extend the progressbar but how to retract or decrement the same progress bar ?

 I was able to decrement using a seperate progress bar

Now on press of boolean switch progress bar should extend and after it completes its output given to and gate plus another retract boolean switch should decrement the same progress bar(using single bar)

can u help me.

Try to logically figure out what would happen if you remove the "AND TRUE" in the upper left and just wire the boolean directly to the case structure. 😄

• First of all, your front panel and diagram are way too big for this VI. Resize them to a reasonable size.
• As already mentioned, that "AND TRUE" is just silly.
• The upper boolean output of the inner loop is the same for both cases, thus it does not belong in the inner case structure at all.
• All you need is a single TRUE diagram constant. Configure the output tunnels to "use default if unwired".
• Try to keep your wires straight.
•  Avoid crossing wires unless necessary
• Change the labels of your controls and indicators to something logical and intuitive. Self-documenting!

Here's a literal rewrite.

sir

I have sent one more query regarding progressbar.Any suggestions how to increment and decrement a single bar using boolean.

A progress bar needs a percentage value, 0-100, do decide fill. How do you plan to translate a boolean to percentage?

If used as direct indicator you can use Boolean to number * 100, but that'll only give empty or full progress bar.

If the boolean is supposed to start a fill, then you have 2 options:

1. While the button is down, increase the fill value (if reduction is needed it can reduce the same if button is up)

2. When the button is switched, activate a boolean in a shift register that controls the fill value.

solution 1 is slightly simpler to write, solution 2 is a better program.
