Using the DNP 3.0 Protocol
The Distributed Network Protocol Version 3.0 (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 9700
Power Meter can be integrated into a DNP network using the DNP Slave
Import, Export and Options modules.

The 9700 Power Meter’s Factory DNP 3.0

Configuration

The 9700 Power 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 9700 Power Meter.
Modules are linked to DNP Slave Export modules which convert the data
into the appropriate DNP objects. These objects are available through the
9700 Power Meter 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 parameters to them. There are 16 DNP Slave
Export modules available on the 9700 Power Meter; of these, 14 are used by
the factory configuration.
