  4. High-available automation system SIMATIC S7-400H with PROFINET I/O System Redundancy (SR) Goals 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. Overview Innovations Redundant Periphery Periphery Open ring architecture § Overview § PROFINET I/O SR-Support through H-CPUs and ET 200M Sync wiring § PROFIBUS I/O Data synchronization High-available communication Guarantee of functionality in the case of an error in a CPU or a ring node or a bus error CPU 41x-5H CPU 41x-5H Failure of an IO device (ET 200M) is limited to the damaged ring node Safety & High availibility Switch Switch Switch PROFINET Cable break between two devices does not affect functionality of the system Applications Failure of a CPU does not affect functionalityof the redundant system References Automatic synchronization after replacement of faulty component ET 200M ET 200M ET 200M E 200M
