MPN: 6ES7 314-1AG14-0AB0 — industrial control spare part, in stock at TGK Parts.
The 6ES7 314-1AG14-0AB0 is the SIMATIC S7-300 CPU 314 — the standard mid-range central processing unit for S7-300 racks, with 128 KB work memory and an MPI interface at 12 Mbaud. It is the CPU most commonly found in production lines, packaging machines and material handling systems built after 2000.
Widely stocked as a replacement spare because CPU failures (battery-backed RAM loss, backplane bus faults) usually force a full controller swap. Available new (sealed) or tested refurbished, with a 12-month warranty and free compatibility verification.
