Communication protocols

Each IED is provided with several communication interfaces enabling it to connect
to one or many substation level systems or equipment, either on the Substation
Automation (SA) bus or Substation Monitoring (SM) bus.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• IEC/UCA 61850-9-2LE communication protocol
