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.

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.
