15.1 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.

15.2.2 Functionality
The IED supports the communication protocols IEC 61850-8-1 and DNP3 over TCP/IP. All
operational information and controls are available through these protocols. However, some
communication functionality, for example, horizontal communication (GOOSE) between the IEDs,
is only enabled by the IEC 61850-8-1 communication protocol.
The IED is equipped with an optical Ethernet rear port for the substation communication standard
IEC 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, 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).
