61850-8-1. IEC 61850-8-1 protocol allows
intelligent electrical devices (IEDs) from different
vendors to exchange information and simplifies
system engineering. Peer-to-peer communication
according to GOOSE is part of the standard.
Disturbance files uploading is provided.
Disturbance files are accessed using the IEC
61850-8-1 protocol. Disturbance files are available
to any Ethernet based application via FTP in the
standard Comtrade format. Further, the IED can
send and receive binary values, double point values
and measured values (for example from MMXU
functions), together with their quality bit, using the
IEC 61850-8-1 GOOSE profile. The IED meets the
GOOSE performance requirements for tripping
applications in substations, as defined by the IEC
61850 standard. The IED interoperates with other
IEC 61850-compliant IEDs, tools, and systems and
simultaneously reports events to five different clients
on the IEC 61850 station bus.
The event system has a rate limiter to reduce CPU
load. The event channel has a quota of 10 events/
second. If the quota is exceeded the event channel
transmission is blocked until the event changes is
below the quota, no event is lost.
All communication connectors, except for the front
port connector, are placed on integrated
communication modules. The IED is connected to
Ethernet-based communication systems via the
fibre-optic multimode LC connector (100BASE-FX).
The IED supports SNTP and IRIG-B time
synchronization methods with a time-stamping
resolution of 1 ms.
• Ethernet based: SNTP and DNP3
• With time synchronization wiring: IRIG-B
The IED supports IEC 60870-5-103 time
synchronization methods with a time stamping
resolution of 5 ms.

Horizontal communication via GOOSE for
interlocking
GOOSE communication can be used for exchanging
information between IEDs via the IEC 61850-8-1
station communication bus. This is typically used for
sending apparatus position indications for
interlocking or reservation signals for 1-of-n control.
GOOSE can also be used to exchange any boolean,
integer, double point and analog measured values
between IEDs.
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.
IEC 60870-5-103 communication protocol
IEC 60870-5-103 is an unbalanced (master-slave)
protocol for coded-bit serial communication
exchanging information with a control system, and
with a data transfer rate up to 19200 bit/s. In IEC
