I believe the right solution - assuming you want to *remove* AND *erase* AND *replace* the firmware on the PLC - is to use a program transfer memory card. A brand new Siemens S7-1200 compatible memory card inserted into a s7-1200 will transfer the program to the memory card. Once the PLC is powered off, memory card removed, and powered back on, it will be empty and ready to load. A safety plc may have a different procedure. Check the s7-1200 system manual for safety integrated s7-1200 PLCs in case there is a difference. I too do not have direct experience using "F" s71200 PLCs.
