SNAP PAC S-Series Controllers
SNAP PAC S-series controller communicates with host
computers through one network interface and controls I/O
with other devices through the other interface.

location #2
This diagram shows multiple Opto 22
SNAP I/O units connected together over an
Ethernet network and controlled by a SNAP PAC
S-series controller running a control strategy.
The controller is also connected to a larger,
separate enterprise Ethernet network to provide
data to two PCs running Opto 22’s PAC Display
HMI software and OptoOPCServer.
Sitting between the two networks, the SNAP
PAC S-series controller isolates I/O and control
traffic from the enterprise network, and vice
versa.
For this system, PAC Display must be configured
to access the I/O through the controller rather
than directly from the I/O units, since they are on
a separate network.
If you are using a Wired+Wireless PAC, one of
these networks could be a wireless LAN.
