Hi, did you try a factory reset of you PLC? After resetting, all data will be copied from MMC to working memory. If this will not work, your MMC could be defect (or also PLC). Please check the following FAQ;: How do you reset a SIMATIC S7-300 CPU and MMC (default reset or overall reset)?Regards, Towome
