What is MMS protocol in IEC 61850?
IEC 61850 MMS (Manufacturing Message Specification) is a client/server based protocol for communications between IEDs (IED – Intelligent Electronic Device) and higher level entities (such as RTUs and SCADAs) over Ethernet that is part of the IEC 61850 standard for communication technology in substations.
What is a Modbus RTU?
Modbus RTU is an open serial protocol derived from the Master/Slave architecture originally. developed by Modicon (now Schneider Electric). It is a widely accepted serial level protocol due. to its ease of use and reliability.
What is MMS in IEC 61850?
IEC 61850 (IEC 61850 – Communication Networks and Systems in Substations) standard defines MMS protocol (Manufacturing Message Specification) as a server/client type communication. The name of each object of IEC 61850 is standardised. Also, IEC 61850 standardizes the access of each object.
Who are the inventors of IEC 61850?

What is the IEC 61850 standard for GOOSE messages?
IEC 61850 standard defines a repetition mechanism for the GOOSE messages that is useful to check that the sender is alive and it is sending the required information. This is an advantage in comparison with the copper wiring where a broken cable may not be easily detected.
Which is communication profile based on IEC 60870-5?
IEC 60870-5 •A communication profile for sending basic telecontrol messages between two systems •Based on permanent directly connected data circuits IEC 61850 Substation Architecture 7
How does IEC 61850 substation architecture 7 work?
IEC 61850 Substation Architecture 7 •IEC61850-enabled IEDs get digitalized power grid condition data via process bus and merge units •IEDs communicate with each other using substation buses •Legacy devices use IEC61850 wrapper
