Lo Lim - This field displays the minimum value of the PV in engineering units before the low limit active bit (LO_ACT) is set. Click this value to enter a new limit.
Lo Lo Lim - This field displays the minimum value of the PV in engineering units before the low low limit active bit (LO_LO_ACT) is set. Click this field to enter a new limit.
Alm Hysteresis - This field displays the alarm hysteresis (or deadband) value for the AI alarms in percent of Out scale. Click this value to enter a new value. An alarm does not recur until the PV has backed away from the corresponding limit by at least the percent of Out Scale specified by this value.
Low Cutoff (LOW_CUT) - Activated when the Low Cutoff I/O option is enabled. When the converted measurement is below the LOW_CUT value, it is shown in the PV as 0.0.
