Features:
- The CPU executes the S7-300 program from 48 KB work memory and MMC load memory.
- Integrated digital, analog, counter, PWM, and positioning channels connect local field functions.
- MPI and the isolated point-to-point port serve different communication paths.
Physical channels enter the configured address map before program logic acts on them.
Technology functions use dedicated terminals and parameters for faster signal handling.
Replacement requires the memory card, hardware setup, communication identity, and field wiring to remain aligned.
The Siemens 6ES7314-6BF01-0AB0 S7-300 CPU 314C-2 PtP Controller may remain available for quotation and support beyond End-Of-Life (EOL) by the manufacturer (OEM).

Connecting stored project data to executable control logic
- Work memory: The CPU executes active code and data within the 48 KB area.
- Load memory: The Micro Memory Card stores the loadable project up to 8 MB.
- Retention: Programmed MMC data remains stored for at least the documented period.
- Startup match: Hardware configuration, block set, and integrated-I/O parameters load together.
Handling fast events outside the ordinary cyclic scan
- Counters: Four channels acquire pulses up to 60 kHz.
- PWM: Four outputs create pulse-width-modulated signals up to the specified rate.
- Positioning: One assigned channel coordinates directional and positioning signals.
- Program exchange: Technology status and values enter the user program through configured interfaces.
Keeping point-to-point traffic separate from MPI
- Physical layer: The second interface uses isolated RS422 or RS485 signaling.
- Protocols: The project selects 3964(R), ASCII, or RK512 communication.
- Cable reach: The point-to-point path remains within the documented 1200 m limit.
- Data handling: Serial telegrams are exchanged through the configured user-program interface.
Restoring program, interfaces, and integrated channels as one controller
- MMC content: The correct project and load memory are present before startup.
- MPI identity: Address and rate match the existing programming and station network.
- PtP settings: Physical mode, protocol, rate, and telegram format match the peer device.
- I/O validation: Every integrated channel is checked against terminal wiring and program addressing.
