Setting the Event configuration property to Floating limit enables the Floating limit extension. This extension detects whether the object's present value exceeds a range defined by a setpoint. The range is comprised of a high-offset, a low-offset, and a deadband. The Floating limit extension can be applied to Analog_Input, Analog_Output, Analog_Value and Pulse_Converter objects.
Selecting the Floating limit extension enables the properties outlined in this table.
Property name | Description |
|---|---|
Object name reference | References the object providing the setpoint. |
Setpoint value reference | A read-only property that references the object providing the setpoint. |
Source property identifier | A read-only property that specifies the setpoint property for the event enrollment object instance. By default, the Source property identifier will display as a property short name (for example, PrVal). But, it can also display as a BACnet property ID (for example, 85). |
Setpoint property identifier | A read-only property that specifies the device object property reference of the setpoint value. |
High difference limit | Specifies the high offset from a setpoint for the normal range. Although the default value of this property is 0, synchronizing it with a negative or zero value will result in a configuration error. Configure this property to a positive non-zero value to clear the configuration error. |
Low difference limit | Specifies the low offset from a setpoint for the normal range. Although the default value of this property is 0, synchronizing it with a negative or zero value will result in a configuration error. Configure this property to a positive non-zero value to clear the configuration error. |
Hysteresis to normal | Specifies the deadband that is applied to the respective limit before a return to Normal event state is indicated. |
Time delay | Specifies the amount of time that must pass between detecting offnormal conditions and sending an event notification. Enter a time in seconds. |
If the Object-Name-Reference is not successfully resolved, object-property-reference shall be set to default, reliability shall be set to configuration-error, and the EEO will not detect event states or issue event notifications.
