hi, redundancy are of two types in siemens plc's 1)Software redundancy (possible with S7 300 & 400 PLC's 2)Hardware redundancy(possible only with S7 400 plc's) Software redundancy is a type of warm redundancy(automatic switchover happens in terms of seconds) which is based on cycle or time synchronisation. Hardware redundancy is a type of hot redundancy(automatic switchover happens in less than 100ms) which is based on event synchronisation. Software redundancy link: http://support.automation.siemens.com/WW/view/en/1137637 Which modules can you use when implementing software redundancy? Hardware redundancy link: Further you can find lots of information in the internet regarding the same. |

Please specify what kind of redundancy do you need - hardware or software. Depending on that solution will differ. |
