Controlling two boolean buttons

[JTShaw]

Hello,

I have two boolean buttons that electrically control one signal (tied together) I need either button to turn off or on the output. I can get the on state no problem using an OR gate but I am have trouble turning them both off with either button. I thought it should have been easy. There must be an easy solution but nothing comes to mind. Any ideas would be welcome.

Thanks,

John

Try XOR instead of OR.

Here is a different way to do it.

Well, either one will turn it on or off BUT if both are on the output goes off not what I need. I need If both are on and either one button is pressed then it turns off the output.

So if I understand:

Start Condidtion = off

1 button on = on

or

2 buttons on = on

If both are on and one is turned off = off

or

If the one button that is on is turned off = off

Correct?

Hey Tim,

Yes you are correct, yours works, I would have liked to do it with just bools but seems a little tricky. Thanks for your example, I'm not sure how easy it would be be integrate into my application.

Cheers,

Can you post your code?

Here is a version that does what you want.

Hi Tim,

Here is the subvi that I need to fix. I can't send the whole code as it is for our research reactor. Your last solution works perfect. I just need to implement it into my code somehow. Thanks for your help.

Can you tell me exactly what you need it to do. I did two inputs but now I am understanding that there are 6?

What is the input to this VI? Is it the cluster with eight controls?

What is the expected result that you expect for each condition?

1 on = 1 on out

1 & 2 on = 1 on out

3 on = 2 on out

3&4 on = 2 on out

etc...
