Any functional substitute would require a full engineering review of the S7-300 slot, backplane power budget, and software porting. For an exact drop-in, this specific order code is the only match. ## FM 8 Expansion & CFC Support CFC (Continuous Function Chart) is supported, allowing graphical interconnection of blocks for process control. Combined with the full command set (binary logic, floating-point arithmetic, jump functions), this CPU suits complex automation tasks requiring sequential and continuous control.","metaTitle":"Siemens 6ES7315-2AF03-0AB0 S7-300 CPU, EOL, FM 8","metaDescription":"End-of-life Siemens S7-300 CPU 315-2 DP.
