HAllo,
I am new with codesys.
I want to convert a INT to a 4 bit binairy number
I have 4 inputs
I connect all the input to a AND Block and the result must be an binairy number
When you say "to a 4 bit binary number", what is it that you mean by "binary number"? A four-character string with each character being either 0 or 1? A numeric variable (of 8, 16 , 32 or 64 bits) with only the four less significant bits assigned (which can code numbers from 0 to 15)?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Any type is binary, in the sense that all values are represented in memory as sequences of 0 and 1. Your INT is already made up of 0 and 1, which you can directly access.
Thanks for your explanation, but I don't quite get it yet. SORRY!!!!
In November i get training :)
Would you mind making an example for me in Codesys?
My example is as follows:
I have 4 inputs (sensors)
If sensor 1 high, output 1000
Sensor 2 high, then make output 0100
Sensor 3 high, then make output 0010
Sensor 5 high, then make output 0001
thanks in advance

Hello
Yes only 0 & 1.
And when it is possible 4digits
0001 or 0101.
When it is 8digits it is also ok

Any type is binary, in the sense that all values are represented in memory as sequences of 0 and 1. Your INT is already made up of 0 and 1, which you can directly access.
For instance, if you have a variable like this :
You can access each bit like this :
You could also use bitwise operators (SHL, SHR, ROL, ROR) to perform bitwise manipulation of values.
Getting specific bits out of a numerical value in CODESYS is therefore easy.
