5.3.5 Analog Inputs

The following table lists Analog Inputs (Object 30). It is important to note that 16-bit and 32-bit variations of Analog
Inputs, Analog Output Control Blocks, and Analog Output Statuses are transmitted through DNP as signed numbers.
The "Default Deadband," and the "Default Change Event Assigned Class" columns are used to represent the absolute
amount by which the point must change before an Analog change event will be generated, and once generated in
which class poll (1, 2, 3, or none) will the change event be reported.
The default analog input event buffer size is set 30. The analog input event mode is set to Most Recent, only most
recent event for each point is stored.
Analog inputs are by default returned in a class zero interrogation.
Note, not all points listed here apply to all builds of devices.
