REU 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 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 startup
Due to implementation differences in DNP master devices, the following
alternative unsolicited reporting (SPA parameter 503V24) startups 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.
