Dear Experts,

                       This is only solution for my case , and i have rectified the my problem also .  

                      The password protected PLC can be reset using SMC card. 24MB SMC Card is required to reset S7-1200 CPU password. If you forgets the password of S7-1200 that was set before and the program and password inside S7-1200 cannot be deleted through "Reset to factory defaults", memory card will become the only way to delete them. The detailed steps are shown as below: Power off S7-1200 equipment Insert a memory card into S7-1200CPU.

                                The program in the memory card shall not have password protection. Power on S7-1200 equipment After S7-1200CPU is powered on, the program inside the memory card may be copied to the internal FLASH register to execute password elimination operation. Customer may insert a brand-new or blank memory card into S7-1200CPU in the same way. After the equipment is powered on, S7-1200CPU may transfer the program in the storage area into the memory card. After pulling out the memory card, user's program will not exist in S7-1200CPU any more, and the password will be eliminated. The contents inside the memory card may be eliminated through card reader. Please refer below attached link for manual "SIMATIC S7 S7-1200 Programmable controller"
