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.

Thank you to those that have participated and provided input in this process of arriving at the new proposed fee structure.  Our member input period ran from February 25th  to June 1st, 2019.  We have listened to your input and made many changes while striving to address our current and projected cash flow needs.  The fee structure for voting is Version 6.0. The member community has also provided good input on directions, value enhancements and new initiatives, many of which now appear on our plans and proposals.

Originally, we had planned to release the new proposed fees on June 3rd with a vote at the meeting on June 20th.  However, we concluded that on a change as significant as this, we needed to connect with more members and give a more flexible opportunity to vote than a single event on June 20th.  Therefore, we have delayed our process for several days to put the following in place:

  1. Release fees and updated information on June 12, 2019.
  2. Develop a voting tool to the Home Page of our website along with a new Voting Information document.
  3. Enable voting (on the website) on June 14 through to midnight (Eastern) on June 30, 2019
