8.21.2 ObjectType Description
8.21.2.1 Variable HighLimit
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.
8.21.2.2 Variable LowLimit
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.
8.21.2.3 Variable Deadband
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.
8.21.2.4 Variable LimitEnable
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.
