Chapter 2 – Network Design
This section describes how to design a Power
Management Control System network on paper so that
actual construction and configuration of the network
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
the appropriate limits.
Using the list of IEDs to be networked, refer to Table 1
and note which communications protocols are required
(commnet or Modbus). For Modbus IEDs, note the
communications speed at which each IED operates. For
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.
When the list of IEDs and the floor plan are in hand,
proceed to Section 2–1 for network design rules.
