SIMATIC S7-300, CPU 315-2 DP, 6ES7315-2AF03-0AB0

Specification Sheet for Siemens SIMATIC S7-300, CPU 315-2 DP, 6ES7315-2AF03-0AB0

Basic Information

• Product Model: 6ES7315-2AF03-0AB0

• Product Series: SIMATIC S7-300

• CPU Type: CPU 315-2 DP

• Application Areas: Chemical, Electronics, Electrical, and other industrial automation fields, where high-performance processing and distributed I/O communication are required.

Hardware Characteristics

• Integrated Interfaces:

• MPI interface for basic communication

• PROFIBUS DP master/slave interface for high-speed distributed I/O communication

• Power Supply: Built-in 24 V DC, allowing a range of 19.2 V to 28.8 V

• Power Protection: External protection recommended (for power supply cables)

• Storage Media: Typically requires a MultiMediaCard (MMC) or other compatible memory media for program and data storage

Memory Configuration

• Working Memory: 64 KByte, providing ample space for program execution and data handling

• Load Memory (MMC/Other): Capacity depends on the selected memory module, but capable of supporting larger programs and data sets compared to models with less working memory

• Retentive Memory: Available for retentive data blocks, ensuring critical data is preserved during power outages

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher, ensuring compatibility with the latest Siemens automation software tools for programming, configuration, and diagnostics

Processing Capabilities

• Enhanced processing performance compared to lower-end models, suitable for more complex automation tasks

• Bit, Word, Fixed-Point, and Floating-Point arithmetic operation times are similar to or faster than the CPU 312, but actual performance may vary depending on program complexity and system load

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs): Typically higher than 1024, allowing for extensive data organization and storage

• Maximum number of Function Blocks (FBs) and Functions (FCs): Also increased, with larger block sizes available to support more complex logic

• Types and quantities of Organization Blocks (OBs): Includes a comprehensive set of OBs for system functions, interrupts, and cyclic tasks, such as OB1, OB10-OB17, OB30-OB38, OB80-OB87, OB121-OB122, and more

• Counters and Timers:

• S7 Counters: Unlimited (limited only by RAM capacity), with retentivity for maintaining count values across power cycles

• S7 Timers: Unlimited (limited only by RAM capacity), also with retentivity for precise timing control in automated processes

Notes

• The above specification sheet is based on publicly available information and may be subject to change due to product updates.

• It is recommended to consult the latest official documentation or contact Siemens technical support for the most accurate information before purchase or use.

• The inclusion of a PROFIBUS DP interface makes this CPU an ideal choice for systems requiring distributed I/O connectivity, enabling seamless integration with other PROFIBUS-compatible devices and systems.
