How can I implement this logic

[tintin_99]

Hi,

I have 3 input parameters. One is a random value .

Inside a loop I read this random value . bsed on this value I would like to select between the other parameters.Let me use an example.

X is the random value. Y and Z are the other 2 parameters. 

1- In the first iteration if X is greater than previous X , I would like to show the value of Z

2- In the second iteration If X< greater than preious X then I would like to keep showing Z if not I show Y

3-  ( lets say we are showing y) In the 3rd iteration If X< greater than preious X then I would like to keep showing Y if not I show Z

So as said the value of X is used to toggle between Z and Y so when the condition is met we keep showing y or Z if not we show the other parameter.

Could you please help me to implement this logic in LV

Thanks

Tried anything yet?

You can do some logic and ranges in the case structure if the input is a number. 

You can also pull up/down the shift register terminals to get the previous n entries of the shift register.

Hi SnowMule,

I have used shift register for X so I continuously read X and compare it with the previous X , but I don't know how can I relate that to select Y and Z. I don't want to select Y and Z if the result is true or false. I would like to continue reading one of them if the condition is true and then read the other one if the condition is false

I have attached my vi but it is not working in a way that I like

Now when the condition is true I see A and when not I see B 

But I would like to see A or B as long as the condition is true and switch to the other one if the condition is false

You only need a shift regsiter with a single output, your solution seems a bit convoluted. 😉

Anyway, if you want to switch whenever the comparison is false, here's what you would do. Modify as needed.
