1.DNP 3.0 Driver Description
The DNP 3.0 Driver allows the FieldServer to transfer data to and from devices over
The following description of DNP is from the DNP User Group internet site.∗
“The development of DNP was a comprehensive effort to achieve open,
DNP is based on the standards of the International Electrotechnical Commission (IEC) Technical Committee 57, Working Group 03 who have been working on an OSI 3 layer "Enhanced Performance Architecture" (EPA) protocol standard for telecontrol applications. DNP has been designed to be as close to compliant as possible to the standards as they existed at time of development with the addition of functionality not identified in Europe but needed for current and future North American applications (e.g. limited transport layer functions to support 2K descriptor transfers for IEDs, RF and fiber support). Recently DNP 3.0 was selected as a Recommended Practice by the IEEE C.2 Task Force; RTU to IED Communications Protocol.
Feature Rich
DNP offers flexibility and functionality that go far beyond conventional communications protocols. Among its robust and flexible features DNP 3.0 includes:
•Output options
•Secure configuration/file transfers
•Addressing for over 65,000 devices on a single link
•Time synchronization and
•Broadcast messages
•Data link and application layer confirmation
DNP 3.0 was originally designed based on three layers of the OSI
DNP 3.0 is very efficient for a layered protocol while ensuring high data integrity.
Suits Any SCADA/EMS Environment
Because DNP 3.0 is based on the IEC
Being an
Users can expect many benefits from using DNP. In the short term:
•Interoperability between
•Fewer protocols to support in the field
•reduced software costs
•No protocol translators needed
