Lifecycle reality — eol_hot means act now
The 6ES7312-5BD00-4AB0 starter kit carries an eol_hot lifecycle stage — Siemens has ended production, and remaining channel inventory is the last available stock. For a line that depends on the S7-300 platform, this is a last-time-buy signal: once existing stock is consumed, the only supply path will be surplus or broker channels. Any BOM still specifying this kit should be reviewed for a migration path.
What the kit delivers — CPU312C plus essentials
The 6ES7312-5BD00-4AB0 is a full starter kit for the SIMATIC S7-300 family, built around the CPU312C. It includes the CPU, a PC adapter with cable, a 160 mm DIN rail, a Micro Memory Card, a front connector, and a manual collection — everything needed to commission a first S7-300 station out of the box.
