Specification Sheet for Siemens SIMATIC S7-300, CPU 315-2 PN/DP, 6ES7315-2EH13-0AB0

Basic Information

• Product Model: 6ES7315-2EH13-0AB0

• Product Series: SIMATIC S7-300

• CPU Type: CPU 315-2 PN/DP

• Application Areas: Chemical, Electronics, Electrical, and other industrial automation fields, particularly suited for complex and high-performance automation tasks

Hardware Characteristics

• Integrated Interfaces:

• 1st Interface: MPI/DP, supporting up to 12 Mbit/s for MPI and DP communication

• 2nd Interface: Ethernet PROFINET, enabling high-speed communication with other PROFINET devices

• Power Supply: External 24 V DC, typically requiring a power supply unit with a range suitable for S7-300 CPUs

• Power Protection: External protection recommended for both power supply cables and communication cables

• Storage Media: Micro Memory Card (MMC) required for program and data storage

Memory Configuration

• Working Memory: 256 KByte, allowing for complex programs and large data handling

• Load Memory (MMC): Maximum capacity depends on the Micro Memory Card used, but sufficient for extensive program and data storage

• Retentive Memory: Available for retentive data blocks, ensuring data persistence across power cycles

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher, providing a comprehensive development environment for programming, simulation, and debugging

Processing Capabilities

• High-performance CPU suitable for complex control algorithms and fast response times

• Bit Operation Time: Typically fast, but specific figures may vary depending on application and system configuration

• Word, Fixed-Point, and Floating-Point Arithmetic Operation Times: Also fast, with floating-point operations being slightly slower due to their complexity

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs): Limited only by MMC capacity and RAM size

• Maximum number of Function Blocks (FBs) and Functions (FCs): Limited only by MMC capacity and RAM size, each with a maximum size as per programming constraints

• Types and quantities of Organization Blocks (OBs): Including OB1 for cyclic tasks, OB10-OB17 for interrupts, OB30-OB38 for error handling, OB80-OB87 for hardware interrupts and other system functions, and many more, tailored to specific automation needs

• Counters and Timers:

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

• S7 Timers: Unlimited (limited only by RAM capacity), with retentivity for maintaining timer settings across power cycles
