Hello manivannan; Software Redundancy (the only type available for S7-300 CPUs) does not really care about levels and versions of CPUs used in the redundant system. You could ieven mplement it with a S7-300 PLC and a S7-400 PLC. The important things you must be aware of are: -the communication interface selected for the redundant link between the CPUs; -the correct setup of the communication and redundancy function blocks required; -the configuration of the redundant I/O used in the application. You can look at the manual for Software redundancy here: http://support.automation.siemens.com/WW/view/en/1137637 The part number for the Software Redundancy license is 6ES7862-0AC01-0YA0. Hope this helps, Daniel Chartier |
