Hello WinCC; Show this quote to your boss; it's from the SWR (Software Redundancy)manual: http://support.automation.siemens.com/WW/view/en/1137637 4.1 How does a system with software redundancy work? Definition A system with software redundancy is characterized by: ● Two S7-300 and/or S7-400 stations that are linked via bus system. ● A redundant user program that is loaded on both stations. ● Two DP master systems to which ET 200M distributed I/O devices with a redundant DP slave interface module such as the IM 153-2 are connected. ● Integration of the blocks provided in the "Software redundancy" package And ask him to: 1) take a good look at the 3rd bullet-point, the one that states that you need a redundant DP slave interface module (IM 153-2 + active bus modules, in this case) to achieve a SWR system. See how the redundant Profibus interface module bundle is described in the Industry Mall:
2) have more trust inthe experience you already have in the matter. Hope this helps, Daniel Chartier |

Deardchartier Thanks for your replay and it help it more. From your statement i understood that two CPU 300/400 series and IM 153-2 with Active Bus is required for R-System. CP module is not required, but redundant block required CP address. This is not clear to me. Can say why CP address is required what for ???? |

Hello Wincc You have three ways to link the two CPU's (see als chapter 6.7 of the manual): 1.)MPI (via CPU onboard port) 2.) Profibus (via CP) 3.) Ethernet (via CP) FC100 (SWR_START) only exists as one generic Block (irrespective of the choosen link) and as such has three Parameters thatrelate to link: 1.) MPI_ADR (MPI address of PARTNER CPU) 2.) LADDR (Logical start address of CP) 3.) VERB_ID (Connection ID) If you choose to link the two CPU's via MPI, you only assign the correct MPI address to the "MPI_ADR" parameter of FC100 (the other two are irrelevant so you assign 0 or any value to them) If you choose to link the two CPU's via CP's (Profibus or Ethernet), youassign the correct CP's "LADDR" AND"VERB_ID"parameterof FC100 (the "MPI_ADR"is irrelevant so you assign 0 or any value to it). Note that an MPI link can only be used to transfer smaller data volumes (max. 1 KB) and that you must copy the blocks for software redundancy from the specified library according to the choosen link (see also chapter 5.2 & 5.3 of manual). |

Dear Wincc, I hope the attach can give you some help. Secondly you can also go to your step7- open project-sample projects and look for sample project "SWR_300_MIN" or "SWR_400_MIN". Good luck. with regards, how come AttachmentSWR Setup Notes.zip (325 Downloads) |
