Can we connect DP/DP coupler with S7 300R (cpu 315 2DP). As the DCS is on Profibus. |

300 R system will communicate with dcs system over profibus via DP DP coupler http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=1179382&caller=viewmanual of DP DP coupler http://support.automation.siemens.com/WW/view/en/19281019check this link |

Hello avi6630 ,
Although the software redundancy (SWR) solution is based on the ET200M (IM153-2), I believe you can still use DP/DP couplers. The point is that you will need 2 DP/DP couplers (One for eachDP master). In DCS, you will configure them as any 2 DP slaves on the same network. You should always inform the DCS which CPU is master or in other words which DP/DP coupler has the correct (latest) data because the DP/DP coupler of thestandby CPU will always have old deceiving data. Justpay attention to the followingparameters of FC 100 ‘SWR_START’. PAA_FIRST --- Number of first output byte used by an ET 200M with redundant-backup IM 153. PAA_LAST ---- Number of last output byte used by an ET 200M with redundant-backup IM 153. Output bytes in the range PAA_FIRST to PAA_LAST must form a contiguous range and may only be used by the ET 200Ms with redundant-backup IM 153s. SLAVE_NO ---- Lowest PROFIBUS address used for an ET 200M DP slave with redundant-backup IM153. SLAVE_LEN--- Total number of ET 200M DP slaves used.PROFIBUS addresses must be allocated contiguously. Do not count DP/DP couplers in these parameters. Best regards. H-H |
