It probably comes from the MMC that is unformatted. Try to use S7imgWR.exe and the attachement hereby. (Find it here, for example: http://personal.telefonica.terra.es/web/suwe/) I am using S7imgWR.exe with my internal desktop MMC reader/writer. It will probably solve your problem but of course will also delete ALL existing data of your MMC. AttachmentMMC_empty_512Kb.zip (167 Downloads) |

Dear murukesh, Perhaps you can reset to delivery state. Here is a link to manual: SIMATIC S7-300 CPU 31xC and CPU 31x Installation See chapter 9.5 Best regards, Wizard |
