The BACnetFloatingLimitAlgorithmType ObjectType is a concrete type and can be used directly.

This OPC UA Property, of DataType BACnetDeviceObjectPropertyReference, references the value that is used as the SetpointReference parameter of the BACnet event algorithm. The DataType is defined in 10.5.10.

The SetpointReference variable value represents a reference to the value that defines the reference interval.

This OPC UA Property, of DataType Float, is the LowDiffLimit parameter for the object’s event algorithm.

Subtracted from the setpoint reference value, the LowDiffLimit variable value represents the lower limit of the range considered normal.

This OPC UA Property, of DataType Float, is the HighDiffLimit parameter for the object’s event algorithm.

Added to the setpoint reference value, the HighDiffLimit variable value represents the upper limit of the range considered normal.

This OPC UA Property, of DataType Float, is the Deadband parameter for the object’s event algorithm.

The Deadband variable value represents the deadband that is applied to the limit before a return to Normal event state is indicated.
