Section 18 Station communication
18.1 670 series protocols
Each IED is provided with a communication interface, 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.
Following communication protocols are available:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
Several protocols can be combined in the same IED.
18.2 DNP3 protocol
DNP3 (Distributed Network Protocol) is a set of communications protocols used to
communicate data between components in process automation systems. For a detailed
description of the DNP3 protocol, see the DNP3 Communication protocol manual.
