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.
