Hello murukesh you can ignore the MPI address Parameter of FC 100 "SWR_START" as your redundant link is a Profibus FDL connection via the CP342-5. I had aquick look at your pogramand a few obvious things stick out which you will need to check and/or change: 1.) Your AG_SEND (FC 5) and AG_RECV (FC 6) are ancient (V 1.11) and can NOT be used in your current configuration (where did you get them from?). Replace them with the latest version from the "SIMATIC NET CP -> CP300" libraryand see also the link below for more on this: Which version of the function blocks do you need to operate a CP 342-5? 2.) You are using FB103 "SWR_SFCCOM" for the communication. This FB is however for redundant links via the MPI port (which in your caseis usedas a DP port for the I/O's). Replace FB103 with FB104 "SWR_AG_COM" as your redundant link is a Profibus FDL connection via the CP342-5. 3.) DB11 and DB12 are configured for non-redundant data transfer of FC 100 "SWR_START", yet they do not appear in your program. 4.) You have two ET200M's in your HWconfig but Parameter "SLAVE_LEN" of FC 100 "SWR_START" is set to 1 (should be set to 2). Just in case you haven't done so yet, I suggest you also have a good read of the SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7 manual, I hope this helps |

Dear Murukesh Well i have attached the Library for SWR V 1.2 for you reference. Please check the loop cable (Profibus) in your case for redudancy looping. Change the cable and see the same, Please tell me if you can see the node address of it. Have fun... AttachmentSwr_lib.zip (400 Downloads) |
