Application Example
Figure 11: Distributed Motor Control Panel
In this Distributed Motor Panel application example, there are two types of interconnect
media being used. The IO and Network Adapter use the Backplane Interconnect while
the motor starters use the QCPort Interconnect cables. In this example, the QCPort
power is supplied through the D77E-QPLR biasing resistor (last module), and the change
from the backplane to the QCPort Interconnect cable is performed there as well.

When powering the QCPort system, the power supply that provides power to the starters
is the same power supply that provides power to the QCPort system. It is important to
size the power supply for the load of the starters and the QCPort load in this application.
Another configuration would include an Automation power supply for the QCPort
components only, and a separate power supply for the IT starters.

All the devices within this example can and will work as designed using one power
supply. For reasons of isolation, a separate DeviceNet power supply would be required
to power the DeviceNet products.
