Hello; The answer is unfortunately quite simple: Siemens does not support Profibus Flying Redundancy over IM 153-2s, with a single non-redundant CPU with redundant I/O stations. Look at the attachments in the following discussion, they shpuld provide information on the subject: https://support.industry.siemens.com/tf/WW/en/posts/about-flying-redundance/14953?page=0&pageSize=10 Siemens supports "Normal Redundancy" over Profibus (which requires either a S7-400H redundant controller pair, or Soft Redundancy), as discussed in the following manual for the S7-400H, and illustrated in the following attachment: https://support.industry.siemens.com/cs/ww/en/view/82478488 Hope this helps, Daniel Chartier |
