17.8.2 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
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.
