Specification Sheet for Siemens SIMATIC S7-400H, CPU 412-3H 6ES7412-3HJ14-0AB0

Basic Information

• Product Model: 6ES7412-3HJ14-0AB0

• Product Series: SIMATIC S7-400H

• CPU Type: CPU 412-3H

• Application Areas: High-availability industrial automation systems, including Chemical, Electronics, Electrical, and other critical process industries requiring fault tolerance and redundancy.

Hardware Characteristics

• Integrated Interfaces:

• 1 x MPI/DP interface for communication and programming

• 2 x Interfaces for synchronization modules (e.g., for coupling with other CPUs in S7-400H or S7-400F/FH systems)

• Power Supply: Typically requires external 24 V DC power supply, with specific voltage range and power requirements as per Siemens specifications.

• Power Protection: External protection recommended for power supply cables and system components.

• Redundancy: Supports hot standby redundancy for high availability (S7-400H configuration).

Memory Configuration

• Total Memory: 768 KB

• Data Memory: 256 KB for storing process data and variables

• Program Memory: 512 KB for storing user programs, blocks, and data

Programming Environment

• Supported Software: STEP 7 V5.x or higher, with specific versions and service packs recommended for S7-400H systems.

Processing Capabilities

• High-performance CPU designed for complex automation tasks and fast response times.

• Processing speeds and operation times will vary based on specific tasks and program complexity, but generally optimized for real-time control and data processing.

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs), Function Blocks (FBs), and Functions (FCs) will depend on the available program memory and system configuration.

• Types and quantities of Organization Blocks (OBs) include standard OBs for cyclic tasks (e.g., OB1), error handling (e.g., OB80 series), and interrupts, as well as specialized OBs for redundancy and synchronization in S7-400H systems.

• Counters and Timers:

• S7 Counters and Timers are available in various types and with retentivity, allowing them to retain their values across power cycles or system resets.

• Quantities are limited only by the available memory and system configuration.

Notes

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

• It is highly recommended to consult the latest official documentation or contact Siemens technical support for the most accurate information before purchase or use, especially when considering the specific requirements of high-availability and fault-tolerant systems.

• Additional hardware and software components, such as synchronization modules, power supplies, and communication interfaces, may be required for a complete S7-400H system configuration.
