Features:
- Compact CPU: Processor and integrated digital I/O share one S7-300 module.
- Built-in counting: Two 10 kHz counters support documented machine functions without separate counter hardware.
- Accessory-dependent service: Memory card, front connector and STEP 7 project must be available for a complete replacement.
The CPU serves legacy compact S7-300 machines that use MPI communications and integrated I/O in a single controller position.
Its 64 KB work memory and fixed onboard channel set define project and wiring compatibility for replacement.
A successful changeout proves startup media, program integrity, communications, counters, I/O and safety interlocks under controlled conditions.
Apter Power can help confirm the Siemens 6ES7312-5BF04-0AB0 SIMATIC S7-300 CPU 312C and documented accessory scope before quotation.
