Remove and reuse S7-1200 memory card help

iauto Posts: 7 Rating: (0)	Hi all, I have a CPU 1212C AC/DC/RL v3.0 which configured with an external 4MB program memory card for testing. It worked well. Now I want to remove this memory card for another application. I already format this memory card as a transfer card and handle transfer program to S7-1200 to use its internal memory instead of external memory card as follow step by step in the manual. But it's not OK, the MAINT led is always yellow flash. Please help me, how to reset PLC to factory settings use its internal load memory after using with external load memory. Thanks in advance.

Now I want to use the same S7-1200 without MMC. Cleaning the MMC does not help, the driver does not want to accept the default settings. Any idea?
