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
• LON communication protocol
• SPA communication protocol
• IEC 60870-5-103 communication protocol
• C37.118 communication protocol
• Syslog (RFC 5424) standard
Several protocols can be combined in the same IED.

Application IEC 61850-8-1

IEC 61850-8-1 communication protocol allows vertical communication to HSI clients and allows
horizontal communication between two or more intelligent electronic devices (IEDs) from one or several
vendors to exchange information and to use it in the performance of their functions and for correct co-
operation.
GOOSE (Generic Object Oriented Substation Event), which is a part of IEC 61850–8–1 standard, allows
the IEDs to communicate state and control information amongst themselves, using a publish-subscribe
mechanism. That is, upon detecting an event, the IED(s) use a multi-cast transmission to notify those
devices that have registered to receive the data. An IED can, by publishing a GOOSE message, report
its status. It can also request a control action to be directed at any device in the network.

Station communication

The LPHD.PhyHealth reflects the physical health of the IED. The status is set to Alarm when
there is an internal failure in the IED or Warning if any active communication link fails.
