This diagram shows two SNAP PAC I/O units connected
together over an Ethernet network and controlled by a SNAP
PAC R-series controller running a PAC Control strategy.
The controller is also connected to a larger, separate
enterprise Ethernet network to provide data to PCs running
Opto 22’s PAC Display HMI software, OptoOPCServer, and
OptoDataLink. Sitting between the two networks, the SNAP
SNAP PAC R1-series
SNAP PAC R-series controller communicates with host computers through one network
interface and controls I/O both directly on the rack and through the other Ethernet interface.
Using a Wired+Wireless PAC, one of these networks can be a wireless one (see the next page).

PAC R-series controller segments enterprise traffic from the
control network.
If you use a Wired+Wireless PAC (SNAP-PAC-R1-W or
SNAP-PAC-R2-W), one of these networks can be a wireless
LAN. See the following page for an example.
Additional I/O units are controlled by the
R-series controller on an isolated network.
