17.10.2 Application
Integer to boolean 16 conversion function (IB16) is used to transform an integer into a set
of 16 binary (logical) signals. It can be used – for example, to connect integer output
signals from one function to binary (logical) inputs to another function. IB16 function
does not have a logical node mapping.
The Boolean 16 to integer conversion function (IB16) will transfer a combination of up to
16 binary inputs INx where 1≤x≤16 to an integer. Each INx represents a value according
to the table below from 0 to 32768. This follows the general formula: INx = 2
x-1
where
1≤x≤16. The sum of all the values on the activated INx will be available on the output
OUT as a sum of the values of all the inputs INx that are activated. OUT is an integer.
When all INx where 1≤x≤16 are activated that is = Boolean 1 it corresponds to that integer
65535 is available on the output OUT. IB16 function is designed for receiving up to 16
booleans input locally. If the BLOCK input is activated, it will freeze the output at the last
value.
Values of each of the different OUTx from function block IB16 for 1≤x≤16.
The sum of the value on each INx corresponds to the integer presented on the output OUT
on the function block IB16.
