High-available automation system SIMATIC S7-400H with PROFINET I/O System Redundancy (SR) Automatic switchover in the event of a fault Event-controlled synchronization of both stations makes for fast and bumpless switchover Redundant CPU picks up processing at the interruption point without loss of information and alarms. All components can be replaced during running operation (hot swapping). When replacing a CPU, it is automatically loaded with the latest programs and data. Open ring architecture SR-Support through H-CPUs and ET 200M/MP Sync wiring Guarantee of functionality in the case of an error in a CPU or a ring node or a bus error Data synchronization CPU 41x-5H CPU 41x-5H Failure of an IO device (ET 200M/MP) is limited to the damaged ring node Cable break between two devices does not affect functionality of the system Switch PROFINET Switch Switch Failure of a CPU does not affect functionality of the redundant system Automatic synchronization after replacement of faulty component ET 200M/MP ET 200M/MP ET 200M/MP ET 200M/MP
