Industry SectorPage 4 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. PROFINET Open ring architecture SR-Support through H-CPUs and ET 200M/MP Automatic synchronization after replacement of faulty component Failure of an IO device (ET 200M/MP) is limited to the damaged ring node Guarantee of functionality in the case of an error in a CPU or a ring node or a bus error ET 200M/MP Cable break between two devices does not affect functionality of the system Failure of a CPU does not affect functionality of the redundant system ET 200M/MP Data synchronization Switch CPU 41x-5H Sync wiring
