The Reference Architecture for Electric Energy OT was developed to address gaps in existing architecture models, and provides a baseline from which domain-specific profiles can be derived. The SEI ETF further developed profiles for four domain-specific applications, including substation, generation, distributed energy resources, and operation/network control center.
SEI ETF members are now working with the International Society of Automation (ISA) to include the profiles in the ISA/International Electrotechnical Commission (IEC) 62443 series of standards.
