| Sector | Electrical substation automation |
A mapping between IEC 61850, the electrical substation automation standard, and OPC UA. It exists because electrical infrastructure and industrial automation have separate standards traditions that increasingly need to exchange data.
Where it sits in the stack
Built on the core information model. The 61850 capability code is registered for servers exposing this mapping.
The types that matter

Using it on a real machine
- Check the capability codeA server claiming 61850 is exposing the mapping.
- Respect the domain boundarySubstation automation has its own engineering culture, safety requirements and change control. Reading data across the boundary is one conversation; writing is an entirely different one.
- Treat it as an energy data sourceFor a manufacturing plant, the useful direction is usually electrical data flowing into plant analytics.
What it gives you for OEE
Electrical supply data rather than production data. Useful alongside OEE for energy per part and for explaining a specific class of downtime - a supply event that stopped a line is not a machine fault, and being able to prove that is worth having.
Gotchas
- Substation automation has its own change control and safety culture. Do not plan writes casually.
- Reading electrical data into plant analytics is the normal and useful direction.
- Supply events explain a category of downtime that machine data alone will misattribute.
Once the machine speaks a companion spec, the OEE mapping is portable across vendors, which is the point at which analytics stops being a per-machine project.
