Hi list,

I should evaluate the changeover time in software redundant configuration for Siemens S7-400. I know that this time is depended on several factors such as CPU type (CPU 414-2 in my case),communication medium (which is MPI), data volume to be transferred (I don't have any data in this regard) and maybe some other reasons. But I'm looking for any criteria/formula (if any) for using a.m. factors in total changeover time.

Thanks,
