synchronization
The IED supports IEC 61850 process bus with sampled values of analog neutral and
phase voltages. Thus, the galvanic interpanel wiring used for sharing the busbar
voltage value can be replaced with Ethernet communication. Sending of sampled
values of analog neutral and phase currents is supported in addition to the voltages.
The neutral voltage is derived from the phase voltages when there is no physical
neutral voltage input available in the IED. The measured values are transferred as
sampled values using the IEC 61850-9-2 LE protocol. Sampled values are intended
for sharing neutral and phase voltages to other IEDs with phase voltage based
functions and 9-2 support. IEDs with process bus based applications use IEEE 1588
v2 Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power Profile for
high accuracy time synchronization.
Configure IEC 61850-9-2 LE with the IEC 61850 Configuration tool
in PCM600 or with the separate IET600 tool. PCM600 interacts with
IET600 by importing and exporting SCL files.

System building

Redundant Ethernet topologies (HSR/PRP) are recommended to be used in the
sampled measured values applications and with GOOSE to ensure the highest
availability.

High-availability seamless redundancy HSR

HSR topology presented here is a reference system for process bus usage with
switches supporting HSR and IEEE 1588 v2. This topology includes an HSR ring with
the protection relays of this product series where IEEE 1588 v2 clock masters are
connected to the ring utilizing Ethernet switches. Ethernet switches filter out IEC
61850-9-2 LE traffic from the IEEE 1588 v2 clock masters. HSR ring is presented
with light blue lines and normal Ethernet connections with dark blue.
