GitHub user ottobackwards added a comment to the discussion: IEC 61850
IEC 61850 is a set of 3 protocol specification: - MMS which does normal kinds of things over tcp - SV which is streamlined for value retrieval (if I recall correctly) - GOOSE which is a link layer high speed data transfer protocol MMS protocol runs on a stack like: TCP TPKT COTP MMS Like S7 does. In fact they both run on port 102. It is possible that some vendors implement it differently though. ABB devices for example seem to leave out parts of the COTP stack. There are zeek analyzers for MMS and GOOSE, and Wireshark support as well. There is an openiec61850 (C) project as well. but that is dual gpl/commeral license.
