sivaji Posts: 5 Rating: (1)	Dear All, I am trying to run a simple S7-300 software redundant program. trying it for two days and no help. finally i need your help to find out where i am making mistake. My configuration. CPU315-2DP with CP342-5 redundant backup link is via CP342-5 I am using AG communication as i am using CP342-5 (profibus for Redundant link) I have attached the screen shot of Netpro where it shows the FDL connection. My both CPU are becomming master and only one CPU goes into Run mode. Mostly Station B goes into run mode. (my biggest doubt what SFC and SFB do i need to download into the CPU along with normal AG Blocks) Example programs SWR-300_mini and SWR-300 each show different SFB and SFC. I want to know how to choose the blocks as there seems to be lot used in SWR_300. Error codes: Statin A Status word : 1000 0000 0000 0101 Station B status word : 1000 0000 0010 1001 Station A : stop mode Station B : Run mode Station A MW details: MW2 : 0 MW4 : 0 MW6 : 8015 MW8 :

If you take a look chapter 3 in SWR manual, you will find that AG send 300 blocks are to be used when you have redundant link of Profibus. Since you use S7-300 CPU you will use 1- FC 100 ‘SWR_START’ 2- FB 101 ‘SWR_ZYK’ 3- FC 102 ‘SWR_DIAG’ 4- FB 104 ‘SWR_AG_COM’ which invisibly invokes the blocks FC 5 ‘AG_SEND’ and FC 6 ’AG_RCV’. FC5 and FC6 must be loaded onto both CPUs. You must keep these functions and function blocks with their original numbers. SFCs and SFBs are not downloaded to the CPU because they already exist as they are part of the operating system. However, they must be existing in your program. Important Note! DB_COM_NO is the instance DB of FB 101 ‘SWR_ZYK’ and is generated by STEP 7. In order that the block can be generated, all system functions used by redundant software backup (SFB, SFC) must be present in your project. A list of the system functions used is given in Technical Data of the Blocks. Where the technical data of the blocks says that these SFCs should be existing in your project SFC 22 ‘CREATE_DB’, SFC 5 ‘GADR_LGC’, SFC 50 ‘RD_LGADR’, SFC 46 ‘STP’, SFC 47 ‘WAIT’ SFC 20 ‘BLKMOV’, FC 5 ‘AG_SEND’, FC 6 ‘AG_RCV’ The point is that you have many area length errors. These errors(in most of casesI saw) comefrom a conflict between the parameters of FC100 and the actual structure of program you download to CPU. Like saying you have 71 DB for IEC timers and counters while you have only 60 DB or saying you have 50 shared data blocks to be transferred between CPUs while you have less than that. In such cases the CPU creates incorrect data blocks for sending and receiving data and it may try to access addresses that may not exist. You can also get some info from this FAQ Such errorsalso may come when you change parameters of FC100 after CPU creates DB_WORK_NO, DB_SEND_NO and DB_RCV_NO. Make sure that DB_A_B_NOand DB_B_A_NO exist inyour program and theyhave the correct length which you assign if FC100. I do recommend (just for trying) to change parameters of FC100 by minimizing length shared data block to one in both CPUs A&B. I mean you will be transferring just one data block for IEC and one shared data block between the CPUs. Make sure that the first IEC instance data block and the first shared data block exist in your program. Make sure that all FCs, FBs, SFCs and SFBs (listed above) exist in your program. Then delete FB101 instance data block (DB5 in your case) from your application program and let SIMATIC MANAGER create instance DB5 again according to the new parameters you have changed. Make sure that your offline program doesn't contain DB1,DB2 and DB3. Delete all blocks in MMC of each CPU. Download your program to both CPUsand try. One more thing, I think it would be better if you upload your software here. Best regards.

I learnt a lot by reading your postingand that also showed me how much i need to learn more in Siemens. I am going to try out all the above and will post you back the outcome. many thanks again Sivaji

sivaji Posts: 5 Rating: (1)	Dear H-H, Your posting solved my S7-300 redundancy problem. Actually the FAQ that you told me to refer was the exact problem solver. I had created several DB's from DB11, DB30 , DB40- DB110 all of them had only one integer. As per that FAQ there should be minimum 2 words. after i increased the word's in each DB the problem got solved. Also i cross checked the SFC and SFB as per Technical data of the blocks and matched them. Great help and my problem is solved. Many thanks again Sivaji
