REF 610-specific DNP features
Time synchronization
If time synchronization (minute-pulse or second-pulse) of the relay's real-time clock
is realized via a digital input, the following applies to the DNP interface of REF 610:
• Depending on the pulse type, either the date-to-minute or the date-to-second
information of the DNP time synchronization message will be used.
• REF 610 will send only one request for time synchronization to the DNP master,
which is at power up.
