The Max-ON CPU is compatible with a wide range of RX3i and Series 90-30 modules, backplanes, and other equipment, as listed in the PACSystems RX3i Hardware and Installation Manual, GFK-2314. Max-ON redundancy applications include fuel loading, standby power generation, boiler systems, and manufacturing systems. The proprietary Max-ON software provides subroutines for synchronization of variables, program equivalence testing, selection of master CPU, and diagnostics. When using Max-ON redundancy, transfer of control from the Master to the Backup can take two to three CPU logic scans. I/O states are maintained during the transfer.
