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 dif
ferential 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
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. 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.
