DNP 3.0 Master/Slave Communication Module
ProSoft Technology, Inc. Page 71 of 129
November 3, 2008
DNP 3.0 Slave Protocol Specifications
The DNP Slave port(s) accepts DNP commands to control and monitor data
stored in the module's DNP Slave databases. If a DNP Master port is also
configured, a portion of these slave databases can be derived from or can control
IED devices connected to the DNP master port.
Report-by-Exception data is logged to the module's database
Supports unsolicited messaging
Each DNP point type is user configurable by point
Class assignments are completely user-definable on a Type and point basis
(BI, AI, FI point types)
The analog inputs are class and deadband configurable on a point basis for
all formats (integer, float)
Supports clock synchronization from a master or from the processor
Support for four octet-strings are supported (object type 110) in the slave
driver to return version and other module information
Up to 400 events are stored for Analog Inputs (AI and FI) and 400 events for
Binary Inputs
In addition to the module generated events, AI and BI events can be
generated in the processor and transferred to the module (useful with
external timestamping hardware)
Configurable event buffer transmission threshold based on count and/or time
since last event transmission
Collision avoidance algorithm per DNP organization for redundant port
switching (redundant slave mode)
Special modem AT command string and timing support for dialing out on
redundant port (redundant slave mode)
DNP 3.0 Master Protocol Specifications
The DNP 3.0 Master port can be configured as a virtual DNP Master device that
actively issues user-defined DNP commands to nodes on the network.
The Master port supports 300 user defined commands, each one containing
its own set of data link and application layer characteristics
Master port logically supports up to 40 slave devices
Individual command configuration includes conditional or continuous polling
and Poll Delay Time
Slave status and Command status available for transfer to the processor
Event data received from the slave devices updates the module database
(Date and Time stamping is not stored or used by module)
Special command handling for Digital Output CROB under processor control
for pulse output control
Supports Report-by-Exception and Unsolicited Responses on a Time Interval
basis or on a user determined Event Count basis. Analog and Binary input
points are supported
