Dear Sir, Can v cofigured Redundancy with CPU-412-2DP--6ES7 412-2XG04-0AB0 in place of CPU-414-2DP. Regards, John |

Dear John, Yes, we can configure redundancy for CPU 412 - 2 DP. Regards |

Hello Omkris; Since this CPU is not enabled for H-systems (hot redundancy) the only available option is Software Redundancy (SWR). SWR allows "normal" S7-300 and S7-400 CPUs to create a dedicated link, over MPI, Profibus-DP or Ethernet CPs, to exchange redundant data between processors. There is a lot of programming involved, since these functionalities are not integrated in the frimware of the CPUs. And your I/Os need to be connected on redundant ET-200M (Profibus-DP remote I/O stations) for your project. That being said, have a look at these documents on SWR to determine whether you are ready to implement it, and if it will do what you need it to do: SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7 Which modules can you use when implementing software redundancy? FAQ collection for SIEMENS PLC soft redundancy Hope this helps, Daniel Chartier |
