Hello patel, I've started very similar project and used your program as sample. I think I've manged configure everything correctly. It looks like everything working normally. One difference in hardware configuration that maybe is related to your PAA_Last problem: configure IM153 modules in station A as usual, and make copy of IM's to station B using Edit>Insert Redundant (in HW Config) . After that in network config, redundant pair of IM's is shown as one block( in your network each IM is shown separately) . Also with PAA_Last configured like it must be, didnt worked for me until i've changed I/O addreses of modules to leave no address gaps. Syncing over MPI is very slow. I've tested with 20 DB >1000Bytes each. It takes >30sec to sync. Im always deleting "DB_WORK_NO" "DB_SEND_NO" and "DB_RCV_NO" on-line when changing FB101 configuration. Worked fine for me. Thank you for good sample :) I'm attaching my testing program if someone needs it. Attachmentpack.zip (135 Downloads) |

Hi all... i tried as per your suggestion. Now it is working. Working means when i changeover from one CPU to other CPU are healthy RUN...THNX DEAR FRITZ.... But one more problem is there. To give solution i think if u first have a look in my project and then suggest me answer..So i attched project with this... FC1 i have written some logic. start-stop logic is written using one input and one mem-bit. Now when i download backup in both cpu,cpu are healthy RUN. Now i give input and two outputs are on simultaneously. It is ok. Now when i changeover from one cpu to other outputs remain on. But when again i changeover to other cpu , outputs goes off. Means after executing logic , for one changeover cycle , outputs remain on and then goes off. I cant get it why....? Attachments7-red_try.zip (164 Downloads) |

Hi dear... Thnx a lot for the detail answer...yes that was the mistake that i am not deleting old data blocks.. now my redundancy is working... Just for your reference i am attcjing you my final program backup which i prepared as sample program. If u can have a look and check if something is wrong/missing in backup and guide me...
