The deadbands for all Analog Input points are in the same units as the Analog Input quantity. For example, an Analog Input
quantity measured in volts has a corresponding deadband in units of volts. This is in conformance with DNP Technical
Bulletin 9809-001: Analog Input Reporting Deadband. Relay settings are available to set default deadband values
according to data type. Deadbands for individual Analog Input Points can be set using DNP Object 34.
