What this CPU packs onboard
The Siemens 6ES7314-5AE00-0AB0 is a SIMATIC S7-300 CPU 314 IFM — a compact CPU with integrated I/O that eliminates the need for separate input and output modules in space-constrained panels. It carries 16 digital inputs and 16 digital outputs, plus 4 analog inputs and 1 analog output, all wired to two 40-pin front connectors. The 24 KB working memory is enough for mid-size machine logic, and the integrated 24 VDC power supply means one less rail to run.
End-of-life reality — no factory support
Replacement planning requires reviewing the S7-300 family or migrating to S7-1200/1500 depending on the control architecture.
Physical fit — panel integration
The two 40-pin front connectors carry the field wiring — the integrated I/O means the wiring plan must account for the fixed I/O map on this CPU, not a configurable slot.
