SNAP PAC S-Series Controllers
PC running PAC Project Professional
In this diagram, two S-series controllers are operating
redundantly. One is the active controller, while the
other acts as a backup, ready to take over should the
first one fail.
Controller redundancy requires PAC Project Professional
9.0 or newer and the Redundancy Option Kit, which
includes the arbiter and the redundant power switch in
this diagram. PAC Redundancy Manager, a software
utility for setting up and maintaining the system, is
included in PAC Project Pro.

SNAP PAC controller
The two controllers you use must be exactly the same
part number (for example, two SNAP-PAC-S2
controllers or two SNAP-PAC-S1-W controllers).
One advantage of an Opto 22 redundant system is that
it uses standard PACs, standard cabling, and standard
I/O. Another advantage is that either controller can act
as the active or backup controller; you can switch their
roles at any time for maintenance, for example.
