Issue
How does Deadband work in the DNP Slave Export Module

Product Line
ION Meters with DNP Slave Export Module Capabilities

Environment
Module Setup

Cause
Need to setup Deadband on the DNP Slave Export Module. 

Resolution
The Deadband value applies to the DNP scaled value of the module as in example below
Setup Registers

  • IONFULL  7200
    IONZERO 0
    DNPFULL  720
    DNPZERO 0
    Deadband 5
In the first second:
  • Input = 6940
    Output - 694
In the next second, it changes to:
  • Input = 7200
    Output = 720
An event will be created (assuming Events are turned on) since the output value changed by more than 5 (the deadband value): 720-694 > 5
