hysteresis is provided on alarms such that
when the alarm is OFF it activates at exactly
the alarm setpoint; when the alarm is ON, it
will not deactivate until the variable is 0.0 % to
100 % away from the alarm setpoint.
Configure the hysteresis of the alarms based
on INPUT signals as a % of input range span.
Configure the hysteresis of the alarm based on
OUTPUT signals as a % of the full scale output
range.
