Analogue Inputs
The following table lists Analogue Inputs (Object 30). It is important to note that 16-bit and 32-bit variations of
Analogue Inputs, Analogue Output Control Blocks, and Analogue 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 analogue 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 analogue input event buffer size is set 30.
Analog Inputs
Static (Steady-State) Object Number: 30
Change Event Object Number: 32
Default Static Variation reported when variation 0 requested: 2 (16-Bit Analog Input with Flag)
Default Change Event Variation reported when variation 0 requested: 4 (16-Bit Analog Change Event with
Time)
