PAC Project Professional includes support for controller-level redundancy when used with identical SNAP PAC S-series controllers and the SNAP PAC Redundancy Option Kit (part number SNAP-PAC-ROK). To use controller redundancy, controller firmware R9.1b or higher is required.
To find out if you can upgrade to this version for free, see the Opto 22 Software Upgrade Policy.
If you are using older (not groov EPIC, groov RIO, or SNAP PAC) controllers or brains with PAC Project, see the SNAP PAC System Migration Technical Note (form 1688) for important information.
