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.
