14.8.2 Application
Boolean 16 to integer conversion function B16I is used to transform a set of 16 binary (logical)
signals into an integer. It can be used – for example, to connect logical output signals from a function
(like distance protection) to integer inputs from another function (like line differential protection). B16I
does not have a logical node mapping.
The Boolean 16 to integer conversion function (B16I) 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
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. B16I 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 B16I 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 B16I.

The sum of the numbers in column "Value when activated" when all INx (where 1≤x≤16) are active
that is=1; is 65535. 65535 is the highest boolean value that can be converted to an integer by the
B16I function block.
