About Controller Redundancy
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.
NOTE: Support for controller redundancy has been restricted to SNAP PAC S-series controllers running firmware version R10.4e or lower using PAC Project versions R9.0 to R10.6. In PAC Project R10.6 and higher, you are no longer able to create new strategies containing controller redundancy. You can continue to maintain existing strategies that have controller redundancy; however, those controllers must use firmware version R10.4e or lower.
Upgrade Information
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.
