Question about Variable

[Bondorudo03]

Hello, wanna ask something about the variable.

This is the sample program i made, the indicator show 0 when i didnt press the pushbutton and show 1 when i press it. however, it turn back to 0 when i release it, is there anyway to keep it as 1 when i release it and the value will keep increasing when i press it?

Attaching an image does not tell us the entire story. Please attach your VI.

• There is no toptlevel while loop. Are you using continuous run mode? Please don't!
• What is the mechanical action of the switch?
• Why are you using a local variable. Where is the terminal of that indicator?
• In LabVIEW, the wire is the variable! Terminals are just UI devices.
• To increment a value, you need to keep the current value in a shift register or feedback node.
• etc. etc.

See if this can give you some ideas:

IF you go to the front panel and right click on the boolean control then select MECHANICAL ACTION there are a few options 

To do what you want you must select SWITCH WHEN PRESSED

... But they said: "and the value will keep increasing when i press it?" That is " ... until released".

Nothing will be increasing without a shift register or feedback node and proper top-level architecture. 🙂

Of course it could also mean that it should increment by one for each press, in that case latch action would be correct

Hi, I'm sorry for not attaching VI

1. Yes, Im using continuous run mode, because i dont want the program to end in one run.

2. the mechanical action is switch when press

3. I put it somewhere else, it is not connected to anything. but the result will be the same even if i use the indicator.
