Hi, We urgently need technical assistance from Siemens to confirm the following : 1) Attached configuration with S7-400 H-system and remote IO is feasible. 2) Confirm that Compressor system 2 can still immediately operate if Compressorsystem 1 is de-energised (ie: No power to Compressor skid 1 RIO rack and Compressor skid 1 OLM). The opposite case for Compressor skid 2 de-energised should also be confirmed. Let me know in case of any Qs. Regards, D AttachmentFibre Option 3.pdf (583 Downloads) |

Hello dshha here's my take on things:
It looks like a rather "odd" PB design at first glance, but itwill - in principle - work
It may is the best answer I can give you, andyou shouldbe aware of the following: - As already stated by Aret, you'll loose proper Segment termination, which may lead to a loss of the other compressor systems RIO rack too. The only way to avoid this is by adding a copper Profibus return line from each skid back tothe other skid and placementof active Profibus terminator there (and ensuring to notexceed permissible Segment lenght) - You will loose the Profibus redundancyand now operate the remaining Compressor RIO rack on a single Profibus/IM153. Opting for a dual redundant FO Profibus will eliminate the above issues and would be my personal Design choice and attached is a sketch on how it would look I hope this helps |

Hi! I believe that the Hw-config should specify the use of optics in the profibus. This is something discussed in the Faq Support. |

Hi dshha, find in attachment solution that I think is good for this. I didn't draw all elements but I think you can figure it out. Best Regards Ensar AttachmentProfibus Skid 1 and 2.pdf (329 Downloads) |

Hello ensark2 your solution will not work as dshhahas a H system and asketch of a workable dual redundant OLM Ring can be found in my first entry in this thread (it's been there for a while, but obviously gets easily overlooked). @ dshha: As for the other optionthat you have and still seem to be searching for, please see TIBI68's second post in this thread. |

The answer is very simple ensark2, S7-400 is not S7-400H Regards. |

Maybe I should change. Why do you think this will not work with S7-400H? |
