Functionality

The IED supports the communication protocol IEC 61850-8-1. All operational information and
controls are available through this protocol.
The IED is equipped with optical Ethernet rear port(s) 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 downloading is provided.
Disturbance files (waveform files in Switchsync PWC600 terminology) are accessed using the IEC
61850-8-1 protocol. Disturbance files are also 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 and systems, and simultaneously reports events to five
different clients on the IEC 61850 station bus.
The Denial of Service functions DOSLAN1 and DOSFRNT are included to limit the inbound network
traffic. The communication can thus never compromise the primary functionality of the IED.
The event system has a rate limiter to reduce CPU load. The event channel has a quota of 10
events/second after the initial 30 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(s) (100BASE-FX).
The IED supports SNTP and IRIG-B time synchronization methods with a time-stamping accuracy of
±1 ms.
• Ethernet based: SNTP
• With time synchronization wiring: IRIG-B
