With the "Software Redundancy" software package, fault-tolerant control systems can be assembled at low cost with standard hardware components of the S7-300 and S7-400.
Software redundancy can be used for applications which do not make high demands for changeover speed, such as:
Control of waterworks or water treatment plants
Control of cooling circuits
Monitoring and control of traffic flows
Monitoring/control of temperature or levels
Depending on the application, the entire process or only parts of it can be redundantly designed.
The following failures are controlled:
The failure of redundant components (PROFIBUS DP master interface, power supply) in a central controller
The failure of a CPU on account of hardware faults or software errors
Interruption of the redundancy link between both central controllers
Interruption of one of the redundant PROFIBUS DP links to distributed I/O
