E.2.4 ANALOG INPUTS
The DNP analog input data points are configured through the

LISTS
ANALOG INPUT / MME POINTS
menu. Refer to the
Communications
section of Chapter 5 for additional details.
It is important to note that 16-bit and 32-bit variations of analog inputs are transmitted through DNP as signed numbers.
Even for analog input points that are not valid as negative values, the maximum positive representation is 32767 for 16-bit
values and 2147483647 for 32-bit values. This is a DNP requirement.
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 Bul-
letin 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.
