Operation principle

The logic for group alarm ALMCALH block is provided with 16 input signals and one
ALARM output signal. The function block incorporates internal logic OR gate in order
to provide grouping of connected input signals to the output ALARM signal from the
function block.
When any one of 16 input signals (INPUT1 to INPUT16) has logical value 1, the
ALARM output signal will get logical value 1.
The function has a drop-off delay of 200 ms when all inputs are reset to provide a
steady signal.
