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 terminology, a primary station is a master and
a secondary station is a slave. The
communication is based on a point-to-point
principle. The master must have software that can
interpret IEC 60870-5-103 communication
messages.
IEC 60870-5-103 protocol can be configured to
use either the optical serial or RS485 serial
communication interface on the COM05
communication module. The functions Operation
selection for optical serial (OPTICALPROT) and
Operation selection for RS485 (RS485PROT) are
used to select the communication interface.
