logic quality bit propagation, each (simple and even combined) signal has quality which
can be evaluated.
The OUT output indicates quality good of the input signal. Input signals that have no
quality bits set or only test bit is set, will indicate quality good status.

QTY_BAD function block

Functionality

The QTY_BAD function block evaluates the quality bits of the input signal and passes it
as a Boolean signal for the application.
The IN input can be connected to any logic application signal (logic function output,
binary input, application function output or received GOOSE signal). Due to application
logic quality bit propagation, each (simple and even combined) signal has quality which
can be evaluated.
The OUT output indicates quality bad of the input signal. Input signals that have any other
than test bit set, will indicate quality bad status.
