This diagram shows a SNAP PAC S-series controller connected
to two separate Ethernet networks. This configuration
addresses the concern that an Ethernet network may fail or
need maintenance, leaving the PC running OptoOPCServer,
the PC running PAC Display, the controller, and the I/O units
unable to communicate.

I/O units are all connected by the controller. Each I/O unit
is connected to its own group of sensors and actuators,
but all are connected to the same two networks.

In this configuration, if one network goes down, devices can
still communicate on the other. Each PC has two network
interface cards (NICs), and the SNAP PAC S-series controller
and the I/O units (SNAP PAC R-series) have two network
interfaces as well.
