EmbedCore-v5 — IEC 61850 IED-side SDK
Turn a conventional protection or bay controller into a compliant IEC 61850 IED in one to two weeks.
EmbedCore-v5 is a library you link into your own device firmware. It publishes your measurements, status points, settings and events as a standard IEC 61850 MMS server, and can also act as a client. The kernel is platform independent and has been deployed across embedded RTOS, Linux and VxWorks targets.
What it does
The package is filled into the device you manufacture and talks to your existing application through a data mapping table, so your control logic keeps running unchanged while the outside world sees a standard IEC 61850 server.
Because the library also contains the client side, the same kernel can be used for a bay-level unit that both serves the station bus and polls downstream devices — one protocol implementation to validate instead of two.
- Telemetry, status, control, set-point, SOE, protection events, setting groups, file transfer and inter-bay interlocking
- Multiple clients served concurrently, with correct behaviour for both synchronous and asynchronous client operations
- Per-port service configuration when the device has more than one network interface
- Service IP taken from the model, not restricted to the host IP address
- Data mapping from heterogeneous sources into one service surface
Modelling without a 61850 specialist
The library ships the modelling layer as well as the protocol layer: logic nodes for the common protection and measurement functions are pre-built, and the package includes an ICD configuration tool plus a tool that maps model data to the device data (currents, voltages, status).
The practical consequence is staffing. A protection engineer who already knows the device can complete the 61850 integration after a short training session, without hiring a dedicated 61850 engineer.
- ICD / CID configuration tool included
- Sample server and client projects showing how each library call is used
- Model-to-device data mapping tool

Frequently asked
Do we get source code or only a binary?
Both models exist. Source delivery is C source plus project files, interface documentation and sample projects under a per-project source licence. A binary library with symbols and a debug build is available for production devices where you prefer not to carry the source.
Which editions and roles are covered?
MMS client and server in the same library, GOOSE transmit and receive, SV subscription, and model/data-set definitions for Edition 1 and Edition 2. SCL parsing and a model consistency check are included, so existing CID/ICD files can be imported directly.
Can we test conformance before committing to a licence?
Yes. A trial build of the test system and a remote or on-site conformance test are available, with a per-clause report. Licensing and delivery start after you have seen the result.
