convert binary signal to numbers

[LeifJoh]

Hi All,

I have been searching and I can't find a simular solution to this issue, so I hope somone can help me. It is probably pretty simple, but as I am new to Labview, it takes some time for me to get used to the programming language.

I have a custom built rotating selector valve with 16 positions. The valve has 5 inductive sensors mounted to a rotating plate with holes drilled for positions.

With 4 sensors there is a binary code created for the 16 positions.

v1 v2  v3  v4

1   1   1   1   pos 1

0   1   1   1   pos 2

1   0   1   1   pos 3

0   0   1   1   pos 4

1   1   0   1   pos 5

0   1   0   1   pos 6

1   0   0   1   pos 7

0   0   0   1   pos 8

and so on..

The fifth sensor is (1) when the valve is rotating and (0) when the valve is in a position.

What I am building with LV is a monitoring system for this valve.

How can I use the 5 digital inputs(simulated with boolean switch) into labview and convert it to a numeric indicator for the position of the valve?

I hope someone can guide me in the right direction with this issue.

Thank you.

Hi LeifJoh,

do you know the function "boolean array to number"?

Is this what you need?

here is a solution

put it together into in an array, invert it, convert it to a number, add 1, DONE 😉

the red dot could be avoided, but that is your homework now 🙂

Thanks Henrik and Mike. Very simple problem but, it takes some time getting used to the block diagram for me 🙂
