Figure 2: DNP MINT in a Communications Network
3.1
INCOM Network
The following simplified rules apply to a given
system consisting of a single daisy chained main
cable link between master and slave devices (see
Figure 2
). For more complex considerations
including star configurations, please refer to the
IMPACC wiring specification T.D. 17513.
•
Recommended INCOM cable styles are
Belden 3073F or C-H style 2A957805G01.
•
The maximum system capacity is 8,000 feet
of communications cable and 16 slave
devices such as the MPCV Relay on the
INCOM network under the DNP MINT.
•
Non-terminated taps, up to 200 feet in
length, off the main link are permitted, but
add to the total cable length.
Make sure that there is twisted-pair wire that is
recommended for IMPACC network use. Use
shielded twisted-pair wire to connect each slave
to the INCOM network, daisy-chain style.
The
polarity of the twisted pair is not important.
3.2
DNP RS-485 Network
The following simplified rules apply to a given
system consisting of a cable link between master
and slave devices (see
Figure 2
).
•
The recommended DNP cable has
twisted-pair wires (24 AWG stranded 7x32
conductors with PVC insulation) having an
aluminum/mylar foil shield with drain wire.
•
Make sure that there is twisted-pair wire that
is recommended for serial DNP RS-485
network use. Use shielded twisted-pair wire
to connect each slave to the DNP network,
daisy-chain style.
The polarity of the
twisted pair is critically important.
