Member Supported Innovation and Development

The DNP Users Group supports our user community and the industry by enhancing and promoting the Distributed Network Protocol (DNP3), 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 TM. Our growing library of Application Notes, Security Notices, and Technical Bulletins provide essential information for our members. The leadership team and Technical Committee provide periodic educational opportunities including tutorials, white papers, and conference presentations. The Test Management Committee supports our large vendor community with conformance testing review services. The DNP Users Group is a California nonprofit mutual benefit Corporation, operating pursuant to United States IRS code 501(c)(6).

The Standard

The latest version of the standard, IEEE Std 1815TM-2012,  was released Oct. 12, 2012. The updated standard contains many changes, including DNP3 Secure Authentication v5, which defines a protocol mechanism that enables a DNP3 outstation/master to unambiguously determine that it is communicating with the correct user/outstation.

IEEE Std 1815-2012 and the accompanying DNP3 Specification Supplement 1 - Device Profile Template and XML Schema are now available for download to DNP Users Group members from the DNP3 Document Library.


We have three events occuring on Monday, February 26, 2024:

  1. Meet and Network Reception - This is a great opportunity to meet the leaders of the DNP-UG, talk about our programs / developments and network with friends.  Hors d'oeuvres and refreshments will be served. 5:30 to 7:30PM at the Hyatt Regency connected to the Orlando Convention Center.  All are invited including those attending the UU courses.  More details to follow.
  2. UU courses on IEEE 1815 (DNP3) are continuing again this year.  Andrew West (Chair of the Technical Committee) is our instructor.  The morning course (8AM to Noon) covers introductory topics whereas the afternoon session (1:00PM to 5:00PM) addresses more advanced and new aspects.  Register on the DistribuTECH 2024 website.
  3. The DistribuTECH website is currently showing the two courses as one combined 8 hour class.  We are working with the organizers to address this.

Membership Matters! Join or Renew Today

Your membership (your company’s membership) is important by enabling the DNP User Group (DNP-UG) to continue to provide the valuable services the industry requires of us. Without strong industry support by both utilities and vendors, we may not be able to continue with the developments we have underway, at least not in a timely manner.

The DNP Users Group (DNP-UG) is pleased to announce the official release of Version 3.1 of our IED Certification Procedures.  For a bit of history, Version 2.8 was released in 2016. Version 3.0 (2021) was a significant update from our previous Version 2.8 and was made available to members on our website.  The Users Group voted to approve Version 3.0 in March 2022.  However, the leadership decided to wait for Version 3.1 to announce the official release that includes scheduled deprecation of the previous version(s).

Both documents represent a very large effort by our dedicated teams on the Test Procedures Committee (TPC) and the Technical Committee (TC). The directors of the DNP-UG would like to sincerely thank all those involved in these developments.
