SIMATIC S7-300 CPU 314 6ES7314-1AG13-0AB0

Specification Sheet for Siemens SIMATIC S7-300, CPU 314 6ES7314-1AG13-0AB0

Basic Information

• Product Model: 6ES7314-1AG13-0AB0

• Product Series: SIMATIC S7-300

• CPU Type: CPU 314

• Application Areas: Chemical, Electronics, Electrical, and other industrial automation fields where higher processing power and memory capacity are required.

Hardware Characteristics

• Integrated Interfaces: MPI interface for communication with other devices and programming devices.

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

• Power Protection: External protection for power supply cables is recommended for optimal operation and safety.

• Micro Memory Card: Requires a Micro Memory Card (MMC) for program storage and data logging.

Memory Configuration

• Working Memory: 96 KByte, providing ample space for program execution and temporary data storage.

• Load Memory (MMC): Maximum capacity varies depending on the MMC used, but typically supports sizes up to several megabytes, allowing for complex programs and large data sets.

• Retentive Memory: The CPU supports retentive data blocks, ensuring critical data is preserved even during power outages. The exact size of retentive memory may vary but is designed to meet the needs of typical industrial applications.

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher is recommended for programming and configuration. Older versions, such as STEP 7 V5.2 + SP1 (with HSP 218), may also be compatible but may lack support for the latest features.

Processing Capabilities

• The CPU 314 offers enhanced processing power compared to lower-end models, enabling faster execution of complex control logic and algorithms.

• Specific operation times (e.g., bit, word, fixed-point arithmetic, floating-point arithmetic) are typically faster than the CPU 312 but may vary depending on the specific configuration and workload.

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs): Designed to support a large number of data blocks, enabling organized storage of program variables and data.

• Maximum number of Function Blocks (FBs) and Functions (FCs): Offers flexibility in program structure, allowing for the creation of reusable and modular code blocks.

• Types and quantities of Organization Blocks (OBs): Supports a comprehensive set of OBs, including those for cyclic tasks (OB1), interrupts (OBs 10-40), errors (OB8x), and startup (OB100), among others.

• Counters and Timers:

• S7 Counters and Timers: Both are unlimited in number, limited only by the available RAM capacity. Both are retentive, ensuring that counter values and timer settings are preserved across power cycles.
