5.1.16.4. 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 the relay:
*
Depending on the pulse type, either the date-to-minute or the date-to-second
information of the DNP time synchronization message is used.
*
The relay sends only one request for time synchronization to the DNP master,
which is at power up.
Unsolicited reporting pick up
Due to implementation differences in DNP master devices, the following alternative
unsolicited reporting (SPA parameter
503V24
) pick ups are available in the relay:
*
1 = Unsolicited reporting starts immediately, without permission from the master.
*
2 = The relay sends an empty unsolicited response message when
communication begins, which the master confirms. After this, the relay starts to
send unsolicited responses.
*
3 = The relay sends an empty unsolicited response message when
communication begins, which the master confirms. After this, the master enables
unsolicited reporting for certain or all classes using function 20. Classes which
are not enabled remain disabled.
Only the last alternative is compliant with the DNP 3.0 standard.
