DNP 3.0 remote communication protocol

The DNP 3.0 protocol was developed by Harris Control based on the early versions
of the IEC 60870-5 standard telecontrol protocol specifications. Today, the DNP
protocol specifications are controlled by the DNP Users Group.

When MSB = 0, bits 14...0
indicate the DI point.
When MSB = 1, bits 14...0
indicate the SPA channel.
In case of a DI event, the
register will contain the DI
value.
In case of an informative event,
the register will contain the
SPA event code.
