Redundant PLC

CPU of CP-7005 type enables the assembly of redundant PLCs (mode Hot-Standby) in 8 racks RM-7942. Four racks are operated by CPU through the bus, other four are connected through system expanders SE-7131/7132. The first group of four racks is redundant (twinned), while the second group of four racks connected through expanders can be operated together from both CPUs. The couple of redundant CPUs CP-7005 is connected each other by two synchronization lines.
