9300 Series User’s Guide Using the DNP 3.0 Protocol
Chapter 3 - Default Meter Functionality Page 61
If your DNP network requires data in a format different than that provided by the
factory DNP configuration, you can edit the setup registers in the DNP Slave
Export modules and the DNP Options module. Do not make any changes to the
DNP Options module’s setup registers unless you understand the effects each
change will cause. Refer to the ION Programmer’s Reference for complete details on
DNP Slave Export and DNP Slave Options module function.
As DNP 3.0 is a very complex protocol, an in-depth understanding of DNP 3.0 is
required to interpret the settings in the DNP Options module and the DNP Slave
Export modules. It is beyond the scope of this meter’s User’s Guide to describe
DNP; consult the DNP User’s Group or other resources to learn more about the
protocol.
DNP Slave Export Module Settings
The 14 factory-configured DNP Slave Export modules are configured as shown in
the following table.
Some setup register settings vary for different modules. Specifically, BasePoint
differs for each module within a group (Analog Input and Binary Counter are
groups), and StaticObj is set to Analog Input for the 11 analog input points and
Binary Counter for the three binary counter points. (StatObj defines the type of
DNP object the module provides when the Master polls it.)
In addition, Scaling is OFF for all but two modules. The only modules that apply
scaling are the Analog Input points that provide Voltage and Current Unbalance
data (labeled Unbalx10) and Frequency data (Labeled Freqx10). These modules
apply x10 scaling.
