cnfg_upper_threshold
Description
upper_threshold_value
The Leaky Bucket operates on a 128 ms cycle. If,
during a cycle, it detects that an input has either
failed or has been erratic, then for each cycle in
which this occurs, the accumulator is incremented
by 1, and for each period of 1, 2, 4, or 8 cycles, as
programmed in Reg. 53 (cnfg_decay_rate), in which
this does not occur, the accumulator is
decremented by 1.
When the accumulator count reaches the value
programmed as the upper_threshold_value, the
Leaky Bucket raises an input inactivity alarm.
cnfg_lower_threshold
Description
lower_threshold_value
The Leaky Bucket operates on a 128 ms cycle. If,
during a cycle, it detects that an input has either
failed or has been erratic, then for each cycle in
which this occurs, the accumulator is incremented
by 1, and for each period of 1, 2, 4, or 8 cycles, as
programmed in Reg. 53 (cnfg_decay_rate), in which
this does not occur, the accumulator is
decremented by 1.
The lower_threshold_value is the value at which the
Leaky Bucket will reset an inactivity alarm.
