connect to a router are logically isolated, so a failure on one channel does
not affect the other channel. For example, in an industrial control
network, isolation among connected cells might be desirable to prevent a
failure in a single cell from bringing down multiple cells. You can achieve
this goal by dedicating channels to individual cells and isolating them
from one another with routers.

traffic within subsystems. For example, in a cluster of industrial cells,
most of the communications might be between devices within cells rather
than across cells. Using intelligent routers across cells avoids forwarding
messages addressed to devices within a cell, thus increasing the capacity
and decreasing the response time of the overall network.
The use of routers across channels is transparent to the application programs
within devices. Thus, you can develop applications without needing to know the
workings of the routers or even if the device's channel will use a router. You only
need to consider routers when determining the network image of a device. When
you move a device from one channel to another, you need only change the
network image. Use a network management tool, such as the LonMaker
Integration Tool, to manage network images.
