Siemens SIMATIC S7-300, CPU 315 CPU 6ES7315-1AF01-0AB0

Specification Sheet for Siemens SIMATIC S7-300, CPU 315 with Integrated 24 V DC Power Supply, 48 KByte Working Memory 6ES7315-1AF01-0AB0

Basic Information

• Product Model: 6ES7315-1AF01-0AB0

• Product Series: SIMATIC S7-300

• CPU Type: CPU 315

• Application Areas: Chemical, Electronics, Electrical, and other complex industrial automation fields requiring high processing power and memory capacity

Hardware Characteristics

• Integrated Interfaces: Standard interfaces may include MPI (depending on model), but specific details on additional interfaces should be verified

• Power Supply: Integrated 24 V DC, allowing a range of 19.2 V to 28.8 V for stable operation

• Power Protection: External protection recommended (for power supply cables) to ensure safe and reliable operation

• Storage Media: Typically requires a MultiMediaCard (MMC) or similar media for program and data storage (specifics may vary)

Memory Configuration

• Working Memory: 48 KByte, providing increased space for program execution and data manipulation compared to lower-end models

• Load Memory (MMC): Maximum capacity depends on the type and size of the MMC used, but is typically sufficient for large and complex applications

• Retentive Memory: Size may vary but typically includes space for retentive data blocks to ensure data persistence across power cycles

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher is recommended for programming and configuration, or STEP 7 V5.2 + SP1 or higher with HSP 218 (if applicable)

Processing Capabilities

• Bit, Word, Fixed-Point, and Floating-Point arithmetic operation times are optimized for high-speed processing, but specific values may vary slightly from the CPU 312 due to architectural differences

• The CPU 315 is designed for applications requiring increased processing power and memory, making it ideal for complex automation tasks

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs), Function Blocks (FBs), Functions (FCs), and Organization Blocks (OBs) are specified by the overall memory capacity and limitations of the CPU. The CPU 315 offers increased capacity compared to lower-end models.

• Counters and Timers:

• S7 Counters and Timers are unlimited (limited only by RAM capacity), providing flexibility for timing and counting tasks within the application. Both counters and timers feature retentivity, ensuring values are preserved across power cycles.
