8.19.2 ObjectType Description

8.19.2.1 Variable HighLimit

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

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

8.19.2.2 Variable LowLimit

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

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

8.19.2.3 Variable Deadband

This OPC UA Property, of DataType Double, 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.

8.19.2.4 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.
