Innovative Technology for Reliable and Secure OT Communications


Our Mission

The mission of the DNP Users Group is to: Actively Develop and Support Improved Interoperability, Cybersecurity, DER Communications, and Education.

Activities of the Users Group

The DNP Users Group supports our user community and the industry by enhancing and promoting the DNP3 (Distributed Network Protocol), also known as IEEE Std. 1815TM. Our members include utilities, suppliers, consultants, and individuals. Many of our initiatives support greater interoperability between supplier’s products and systems and/or enhance cyber security. On-going refinements also add new features and time-saving capabilities which are then included in the next update of IEEE Std 1815. Our growing library of Standards, Application Notes, Guides, Security Notices, and Technical Bulletins provide essential information for our members. The leadership team and technical team members provide periodic educational opportunities including tutorials, white papers, and conference presentations. The technical teams are involved with four different groups as follows:

  • Technical Committee
  • Cybersecurity Task Force
  • Test Management Committee
  • Test Procedure Committee.


Recent and current developments include new:

  • Test procedures.
  • Device profile guide.
  • Secure Authentication v6 (SAv6).
  • Authorization Management Protocol (AMP).
  • Update to the IEEE Std 1815 standard.
  • DER communications standard – IEEE 1815.2TM (draft) – joint effort with MESA.
  • Expanded Conformance Certification Program (CCP).
