The IEC 61850 Protocol Server allows up to 6 simultaneous MMS clients.

Either Ethernet port can be configured for IEC 61850 (only one port at a time can run IEC 61850)

GOOSE publisher/subscriber functionality is supported.

Buffered and unbuffered reports are supported for the following triggers: general meter interrogation, for example, the report is generated in response to a query; meter integrity, for example, the report is generated according to a programmed interval; and data change, for example, the report is generated due to a change in the contents of a dataset.

File transfer is supported

Embedded Web Protocol Server support is available for IEC 61850 CID file uploading, IEC 61850 Protocol Server status and for displaying incoming and outgoing GOOSE messages.
