Hello AK123 First of all you should not normally have CPU memory >80% full . Having said that : a) Optimise your PLC Program to reduce size. b) Minimise the Redundant Data Area ( No and size of Data blocks& Flags ) c) Ensure that all the Redundant DBs are in continuation ( No missing blocks ) d) Use a Profibus CP342-5 for Redundancy connection ( You can go upto 12MBPS instead of 187.5kbps of MPI ) e) Use a Higher CPU Hope this helps Cheers Navnag |
There is no such thing as the last bug in a program |

HiPrads To test your software and switching time. first connect ONE WinCC Station to the redundant PLC and try a test appliccation for the WinCC and CPU software, also read this manual "SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7" well and revise all setting on the PLC and WinCC. If you got a reasonable change-over switching time, then try the next step to add a WinCC redundant station and make all possible switching tests, until you get satisfied to the results. Finally, add the clients and operate the application software that you have. |
Best Regards |
