Property Value

The hysteresis is an offset that provides padding between the point at which the alarm is raised and the point at which the alarm is cleared. For example, in the case of the GreaterOrEqual operation:

• Raised: value >= SetPoint
• Cleared: value < SetPoint - Hysteresis

The direction of the offset depends on whether the operation is greater than (or equal) or less than (or equal). The hysteresis must be greater than zero.
