IEC 60870-5-103 is available from optical
serial port where it is possible to use serial
glass fibre (ST connector) or serial plastic
fibre (snap-in connector).
The IED supports SNTP, DNP3 and IRIG-B
time synchronization methods with a time-
stamping resolution of 1 ms.
The IED supports the following time
synchronization methods with a
timestamping resolution of 1 ms:
Ethernet communication based:
• SNTP (simple network time protocol)
• DNP3
With special time synchronization wiring:
• IRIG-B (Inter-Range Instrumentation Group
- Time Code Format B)
IEC 60870-5-103 serial communication has a
time-stamping resolution of 10 ms.
