IEC 61850 Client Configuration in SEL RTAC
Key Takeaway
How to configure the RTAC as an IEC 61850 MMS client and GOOSE subscriber — SCL file import, logical node mapping, GOOSE subscription, and modern IED integration.
Quick Answer
The RTAC supports IEC 61850 MMS client (reads data from IEC 61850 servers), GOOSE subscriber (receives sub-millisecond Boolean messages from IEDs), MMS server, and GOOSE publisher. Import IED CID/ICD files to browse logical nodes and map data to RTAC tags.
MMS Client
- Add IEC 61850 client driver
- Enter target IED IP address
- Import the IED's CID or ICD file
- Browse logical node structure (LD/LN/DO/DA)
- Select data attributes to subscribe
- Map to RTAC tags
GOOSE Subscriber
Configure GoID, AppID, and multicast MAC. Map dataset Boolean values to RTAC BOOL tags. Sub-millisecond latency for protection applications. See SEL IEC 61850 guide.
SCL Files
ICD (IED Capability Description) describes what data an IED provides. Import into ACSELERATOR RTAC to browse available data without manual entry.
Testing
Use Wireshark GOOSE capture to verify multicast traffic on the substation LAN.
