Chapter 2 - Network Design
This
section
describes
how
to
design
a
Power
Management Control System network on paper so that
will proceed smoothly.
You need two things for this exercise: a complete list of
the IEDs to be networked and a diagram or map of
where the IEDs will be located, preferably with realistic
distances noted so that wiring runs may be kept within
an
the appropriate limits.
Using the list of IEDs to be networked, refer to Table
I
and note which communications protocols are required
(commnet or Modbus). For Modbus IEDs, note the
communications speed at which each lED operates. For
tM
IEDs supporting both protocols, you will need to decide
which protocol will be used. Generally, it is preferable to
use Modbus rather than commnet unless the Modbus
network is at or near capacity for physical IEDs.
