15.3.6 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.
