Using the DNP 3.0 Protocol
The Distributed Network Protocol Version 3.00 (DNP 3.0) is an open protocol used
in the electric utility industry for communications and interoperability among
substation computers, RTUs, IEDs, and Master Stations. The 9300 can be
integrated into a DNP network using the DNP Slave Import, Export and Options
modules.

Factory DNP 3.0 Configuration for the 9330 and 9350
The meter’s factory configuration makes various parameters available through
DNP 3.0. There is no factory-configured functionality for importing DNP 3.0 data
into the meter. ION modules are linked to DNP Slave Export modules which
convert the ION data into the appropriate DNP objects. These objects are available
through the meter’s communications port that is configured to use the DNP 3.0
protocol. The DNP Options module sets global options for all of the DNP Slave
Export modules.

Changing the DNP Configuration
If the factory DNP configuration does not suit your needs, the existing DNP Slave
Export modules can be relinked to other parameters that you want to access
through DNP. Alternately you can add additional DNP Slave Export modules and
link the desired ION parameters to them. There are 16 DNP Slave Export modules
available on the 9330 and 9350; of these, 14 are used by the factory configuration.
