Bad Signal Quality Qty_Bad - ABB RELION REX640 Technical Manual

Basic functions
3.19.1.2 Functionality
The good signal quality function QTY_GOOD 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 (except preprocessing
block). Due to application 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.
