DNP communication
This chapter outlines the Distributed Network Protocol (DNP).
DNP allows for the optimization of control and data acquisition between the equipment in
the substation and the central control center. It improves upon many master-slave
protocols by improving overall communication performance requirements and provides
time-stamping with millisecond accuracy.
This section represents a 'device profile document' defined by the DNP 3.0 subset
definitions document. The DNP implementation table is located in the following section.
• Vendor name — General Electric Multilin
• Device name — D90
• Highest DNP level supported:
– For requests — Level 2
– For responses — Level 2
• Device Function — Slave
• Notable objects, functions, and qualifiers supported in addition to the highest DNP
levels supported:
– Binary inputs (object 1)
– Binary input changes (object 2)
– Binary outputs (object 10)
– Control relay output block (object 12)
– Binary counters (object 20)
– Frozen counters (object 21)
– Counter change event (object 22)
– Frozen counter event (object 23)
– Analog inputs (object 30)
