Hi All, I am using CPU 315 2 PN/DP with CP 342-5 redundant link. I am facing problem to configure this system. I went through all the threads which mention in siemens site. some one ask to do the 1.FDL connection between the CP 2. call AG-SEND ) FC-6 ( AG RECV) please advice me how to configure this redundancy. please provide me sample backup for the same. see the attached backup of my project.

Hello kiranPCT had a quick glance at your project and few things stick out: 1.) You've connected your CP342-5 to different Profibuses in Netpro (each one is connected to one of the redundant DP Networks). --> Fix this by creating a new Profibus network to which both CP342-5's are connected 2.) The configuredNetpro link between the two stations (via CP342-5) exisitsonly in one station. --> Fix this by creating specifed connection between the two stationsso that the connection exists in both CPU's. 3.) FB104 "SW_AG_COM" is missing fromyour project (this block is required if you use a CP andFC5/6 based connection). --> Fix this by adding FB104 to your project and downlaod it to the CPU (make sure you add it from the "AGSEND_300" package") There may be other issues, but the abovedefinetely needsto be sorted out (you can also get rid of FC1-4 which are not needed as you do NOT use the CP342-5's for the Profibus I/O's). I suggest you also have a good read of the SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7manual. Note that chapter 7 has a well describedexamplethat uses CP342-5's for the link between the CPU's (from memory,you'll also find example S7 projects on the CD that came when you bought the software redundancylicense). I hope this helps |
