[john7]

Hi All!

I have boolean array. I need to chek if more than one element of array is true, if so it's faul state. How can i do it?

Hi john7,

see the "boolean array to number" function and check the result.

Hi  MikeS81! If i use boolean array to number wich number indicates two bits set high? I should go and scan all cases. It's not so elegant especially if array is varying in size.

Use "boolean to 0,1" (it also works for boolean arrays) followed by "add array elements". If the resulting sum is >1, you have a fault.

Hi,

Check the attached vi. I have used a conditional for loop. (not sure if it is the best solution)

Hi,

Hi John,

use Boolean to 0/1 and a ArraySum function...

Oops, shouldn't look at other websites in the mean time

Thank you guys! Absolutelly perfect!

Also, if you expect the possibility that the boolean array is larger that 2^15 (32k), you need to convert the output of boolean to 0,1 to I32 before taking the sum.
