hi Mr Luke first thank you for you quick reply. following your advice - i couldn't reload the series start up archive available within the Services area (see pic 1and 2) - i checked cables they are all right but there is a switch (on/off) in x101 and x102 from ncu and pd/mpi in the mmc. i think they should be all on? - using simatic manager to check accessible nodes i found that we only have PLC with adress 13 please not there are two empty objects in that module (see pic 3 and 4) any suggession ? realy i'm very thankfull AttachmentPhotos.zip (267 Downloads) |

Hello, Only two terminators resistors of network must be ON & others must be OFF. Please check the actual status. Please check default address as mentioned in attached sheet, MCP = 6, PLC MPI = 2, FM NCU = 3 HTH. Please confirm the series start up arc which you are trying to read is the latest one or old one. If any hardware modification is carried out of which series start up is not taken, then most probably you may face error while loading/reading the back up.
