Using the DNP 3.00 Protocol
The Distributed Network Protocol Version 3.00 (DNP 3.00) is an open protocol
used in the electric utility industry for communications and interoperability
among substation computers, Remote Terminal Units (RTUs), Intelligent
Electronic Devices (IEDs, e.g. meters), and Master Stations. The meter can be
integrated into a DNP network using the DNP Slave Import, Export and Options
modules.
The Factory DNP 3.00 Configuration
The meter’s factory configuration makes various parameters available to export
through DNP 3.00. There is no factory-configured functionality for importing DNP
3.00 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 ION
7500 or ION 7600 meter’s communications port that is configured to use the DNP
3.00 protocol. The DNP Options module sets global options for all of the DNP
Slave Export modules.
The meter is shipped from the factory with the following DNP static objects
defined. The following objects are returned in response to a Class 0 Poll. Note that
the protocol of the desired communications port must set to “DNP 3.00” before the
meter will respond to DNP master requests.
