ABB REC650 - Technical Data

Synchronization via DNP
The DNP3 communication can be the source for the coarse time synchronization,
while the fine time synchronization needs a source with higher accuracy. See the
communication protocol manual for a detailed description of the DNP3 protocol.
Synchronization via IEC60870-5-103
The IEC60870-5-103 communication can be the source for the coarse time
synchronization, while the fine tuning of the time synchronization needs a source with
higher accuracy. See the communication protocol manual for a detailed description of
the IEC60870-5-103 protocol.

15.3 Parameter setting group handling
15.3.1 Functionality
Use the four different groups of settings to optimize the IED operation for different
power system conditions. Creating and switching between fine-tuned setting sets,
either from the local HMI or configurable binary inputs, results in a highly adaptable
IED that can be applied to a variety of power system scenarios.
