Product Details:

Additional Information:

Description:

The PACSystems* RX3i Max-ON CPU IC695CMU310 provides Hot-Standby CPU redundancy using two RX3i systems. The redundant controllers exchange operating data by way of one or two dedicated Ethernet LANs. Each RX3i system in a Max-On application consists of:

▪ the Max-ON CPU (IC695CMU310)

▪ an RX3i Universal Backplane (IC695CHS0xx)

▪ an RX3i power supply (IC695PSxxxx)

▪ one or more RX3i Ethernet modules (IC695ETM001)

▪ Max-ON application software

▪ Optional Series 90-30 expansion backplanes.

▪ PACSystems RX3i and/or Series 90-30 modules, as appropriate for the application.

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. Max-ON redundancy is not suitable for SIL 2 or 3 applications.
