This OPC UA ObjectType represents the BACnet unsigned out of Range event algorithm.

The BACnetUnsignedOutOfRangeAlgorithmType is formally defined in Table 66.

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

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

The HighLimit value represents the upper limit of the range that is considered normal.

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

The LowLimit value represents the lower limit of the range that is considered normal.

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

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

This OPC UA Property, of DataType BACnetLimitEnable, shall indicate three separate flags that enable and disable the delivery of TO_OFFNORMAL, TO_FAULT, and TO_NORMAL notifications. The DataType BACnetLimitEnable is defined in 10.3.4.
