MESA-DER De Facto Standard

MESA publishes an open, non-proprietary de facto standard that maps the IEC 61850-7-420 information model to specific DNP3 data points to achieve interoperability. The MESA-DER de facto standard is comprised of three parts:

  • The MESA-DER Specification (freely available)
  • The MESA-DER DNP3 Application Note (available to MESA members and DNP User Group members)
  • The corresponding MESA-DER spreadsheet used for electronic access to the mapping data, and  also used for MESA Phase 1 Testing (available to MESA members)
