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 and DNP3
• With time synchronization wiring: IRIG-B
The IED supports IEC 60870-5-103 time synchronization methods with a time
stamping accuracy of ±5 ms.
