Hi, I have 3 questions about software redundnacy. I Have 2 CPUs 315 pn/dp with 2 CP343-1. The redundant link is made with CP343-1 (ISO ON TCP Connection). [schnippschnapp] Wincc communicates with the plc via ethernet (IE general). i use the wizard from wincc to create redundant connection. The problem is when i manually create a profibus error at the master CPU, the satndby CPU becomes master but the wincc dont switch the connection after the profibus error (is connected at the standby CPU which was master before the profibus error). How i can solve this problem? [schnippschnapp] Thang you Splitted from s7-300 software redundancy Ammount of Data. |

Hello autom not too sure what type of redundant connection you configured in WinCC, but suggest you have a look at chapter 9.1 of the SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7 manual first, followed by the Software Redundancy help from the WinCCInformation system(you'll find it in yoru WinCC program group, see attached screendump too). If you follow the instructions contained in them your connection should should change over as expected and I hope this helps. |
