These include not just encryption but other practices that enhance security against well known intrusion methods.


It was developed for communications between various types of data acquisition and control equipment. Although the protocol was designed to be very reliable, it was not designed to be secure from attacks by hackers and other malevolent forces that could potentially wish to disrupt control systems to disable critical infrastructure.

The protocol is robust, efficient, and compatible with a wide range of equipment, but has become more tutoriial and subtle over time. Feel dpn3 to post them below.

Overview of the DNP3 Protocol

As subcommittee chair, DNP3 became an IEEE standard and many standards have been updated, new standards created, and even newer standards are under development. His first experience with Campbell equipment came soon after graduating from college while working on a series of plant-growing experiments conducted on the International Space Station.

How is DNP3 different from Modbus? Ron Farquharson and Craig Preuss. May 17, — Sunday 8: Benefits and Options Purchase Membership. Share This Article Email. Its main use is in utilities such as electric and water companies. For a number of years, our data loggers have supported the DNP3 protocol.

While IEC was still under development and had not been standardized, there was a need to create a standard that would allow interoperability between various vendors’ SCADA components for the electrical grid. Increasingly demanding industrial applications are part of the challenge. DNP3 Distributed Network Protocol is a set of communications protocols used between components in process automation systems.


Stay informed with our latest updates by following us on these platforms:. He has assisted utilities with program reviews, requirement developments and procurement documentation. The DNP3 protocol is commonly used to report event and historical data to SCADA systems in the water and energy sectors in the United States, as well as in other countries throughout the world. The development of DNP3 was a comprehensive effort to achieve open, standards-based Interoperability between substation computers, RTUs, IEDs Intelligent Electronic Devices and master stations except inter-master station communications for the electric utility industry.

Do you have DNP3 comments or questions?

Weather stations based on Campbell Scientific data loggers are used worldwide because tutotial their capability, flexibility, accuracy, and reliability. Retrieved from ” https: All articles with unsourced statements Articles with unsourced statements from January The DNP Protocol has time stamped variants of all point data objects so that even with infrequent RTU polling, it is still possible to receive enough data to reconstruct a sequence of events of what happened in between the polls.

Stay informed tutogial our latest updates by following us on these platforms: After an Integrity Poll, only significant data changes are sent.

This causes the Remote Terminal Unit to send all buffered events and also all static point data to the Master station. The Remote Terminal Unit can also be configured to spontaneously report Class 1, 2, or 3 data, when it becomes available. A key part of the methodology is a highly collaborative approach based on use-cases to identify multi-stakeholder requirements. The User Group also maintains a comprehensive website with wide range of resources for its members.

As the needs tutorizl our customers evolve, we continue to add enhanced DNP3 functionality to our data logger operating systems.

Getting to Know DNP3

The DNP3 protocol tjtorial significant features that make it more robust, efficient, and interoperable than older protocols such as Modbusat the cost of higher complexity.

The previous version of secure authentication in IEEE used pre-shared keys only. As part of these engagements, he has developed an effective methodology for roadmap development that includes technology assessments, standards maturity, gap analysis, regulatory compliance and risk assessments.

As ambitious an undertaking as this was, we reached this objective. A Remote Terminal Unit for the DNP3 protocol can be a small, simple embedded device, or it can be a large, complex rack filled with equipment.

It makes heavy use of cyclic redundancy check codes to detect errors. Set up your preferences for receiving email notifications when new blog articles are posted that match your areas of interest. DNP3 has been designed to tugorial 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.

Overview of DNP3 Protocol. This includes conceptual design; cost justification; technology assessments; equipment specification, procurement and selection; system architecture for substation networks of all kinds; cyber security; detailed design including logic, drawing development, and programming; testing; and commissioning.

Because smart grid applications generally assume access by third parties to the same physical networks and underlying IP infrastructure of the grid, much work has been done to add Secure Authentication features to the DNP3 protocol.

This improves compatibility and eliminates problems such as endianness. Please log in or register to comment.
