Hello sks_karthik; Since this is not a S7-400H unit, available for hardware redundancy, Software redundancy is your only solution. Have a look at the manual for Software Redundancy: http://support.automation.siemens.com/WW/view/en/1137637 If you do a search here on the forum (the Search button is on the top right side of this page) you will have access to many threads on the subject by users here, and also FAQs and application examples. Just one example: http://support.automation.siemens.com/WW/view/en/2812567 Hope this helps, Daniel Chartier |

Hello SPV; I am afraid there is no hardware redundancy even on the CPUs for the ET 200Pro (or any other ET 200 family, for that matter). The closest you will find when you look at information available on the IN 154-8 CPU:
IM 154-8: CPU with PLC functionality equivalent to S7-315-2 PN/DP, provides distributed intelligence for preprocessing So basically coulkd do Software Redundancy on these ET 200 CPUs, but you would be in the same spot as before. Hope this helps, Daniel Chartier |

Dear SPV, You may also one to consider using ET200M, IM153-2, 6ES7 153-2 BA02 0XB0. Hope this helps! with regards, how come? |
