This component is a special-purpose alarm extension, especially for the use as a child of a LoopPoint component. It provides alarming as a deviation from the current setpoint (plus or minus), using offnormal properties errorLimit and deadband. As of Niagara 4.14, when the Low Diff Limit Enabled property is set to true, a Low Diff Limit is defined that may differ from the existing error limit. Once Low Diff Limit Enabled is set to true, the Low Diff Limit property will be used by the algorithm.
