Software redundancy – the cost-optimized solution

With the SIMATIC S7 software redundancy package, production-critical pro¬ces¬ses can be controlled on a fault-tolerant basis with the SIMATIC S7-300 and/or SIMATIC S7-400 standard automation systems for the very first time.

Thanks to this cost-effective software solution, production failures can be avoided when a fault occurs or when maintenance is being done. Many applications involve relatively slow processes which place few demands on the time needed for a switch-over in the event of a fault. The SIMATIC S7 software redundancy solution can therefore be used for the redundant control of pro¬ces¬ses for which a master-to-standby switch-over period in the seconds range is more than adequate.
