Features:
- Integrated digital I/O and technology channels place local signal processing beside the CPU.
- Three counters and pulse outputs execute high-speed measurement and output tasks.
- Separate MPI and PROFIBUS DP interfaces divide engineering communication from distributed-I/O networking.
The CPU executes logic from work memory while the Micro Memory Card holds the load-memory image used for project transfer and restoration.
Its PROFIBUS connection can control distributed devices as a DP master or exchange data under another master as a DP device.
Integrated diagnostic storage and front LEDs provide two complementary views of controller events and physical signal states.
The Siemens 6ES7313-6CG04-0AB0 SIMATIC S7-300 CPU 313C-2 DP Compact CPU may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Local Signal Organization
- Standard inputs: Sixteen digital channels deliver ordinary 24 V DC field states to the CPU process image.
- Standard outputs: Sixteen protected channels switch connected loads under the user program.
- Technology inputs: Dedicated channels feed counting and frequency-measurement functions without depending only on the cyclic scan.
- High-speed outputs: Selected output channels generate pulse and PWM signals for technology tasks.
Two Communication Roles
- MPI network: The first interface serves programming devices, operator panels, and S7 communication at 187.5 kbit/s.
- DP master: The isolated PROFIBUS port can cyclically control distributed I/O stations.
- DP device: The same interface can exchange assigned data under another PROFIBUS DP master.
- Network scale: The configured DP master system can address as many as 124 distributed devices.
Integrated Technology Processing
- Counting: Three channels acquire pulse trains at rates through 30 kHz.
- Frequency measurement: The same technology hardware converts incoming pulses into measured frequency values.
- Pulse generation: Three outputs can create pulse trains at rates through 2.5 kHz.
- PID execution: Integrated control functions process configured loops within the CPU program environment.
Program Retention and Event Review
- Work memory: The CPU executes code and live data from its integrated 128 KB memory.
- Load memory: A required Micro Memory Card stores the project image used for loading and backup.
- Battery-free backup: Program and data retention does not depend on a backup battery.
- Event record: The diagnostic buffer holds 500 entries, including 100 retained after a power failure.
