Data Communication ProtocolData Communication Protocol
- Key Element for Substation Automation
- Protocol required to interpret the data at both ends ofcommunication system in same way
- Conventional Protocol Tag + Data
(Tag mapping table required for system integration)
- IEC61850 Protocol Context + Data
(Context is defined in the IEC61850 Standard.)
