S7-1200 (6ES7 214-1BG40-0XB0) I have the same problem... Steps until it die: -> Update Firmware 4.1 to 4.2. -> Downloaded program with WebServer and watch table 2000 variables type REAL (works perfectly). -> Added more 2 DB's with 300 REALs each (works fine) -> Added 2 watch table for this 300+300 variables -> PLC crashs, i'm unable to download any program but it appears the option to connect and donwload but never do it till the end -> Put the PLC in RUN mode and i'm not able to connect to it again. -> Unplug and Plug and this starts with 3 leds flashing at all time (Unable to ping or download, even "online access" - networkcard - Update accessible devices doesn't show my S7-1200 anymore). ------------------------------------------------------------------------------------------ |
