Siemens SIMATIC S7-400H, CPU:412-3H 6ES7400-0HR00-4AB0

Specification Sheet for Siemens SIMATIC S7-400H, 412-3H System Bundle 6ES7400-0HR00-4AB0

Basic Information

• Product Model: 6ES7400-0HR00-4AB0

• Product Series: SIMATIC S7-400H

• System Configuration: H-system bundle with redundant CPU setup

• CPU Type: 412-3H

Application Areas

• Process automation in chemical, oil & gas, water treatment, power generation, and other heavy industrial sectors requiring high availability and redundancy.

Hardware Characteristics

• Redundancy: High availability system with dual CPUs (412-3H) for automatic failover in case of failure.

• Integrated Interfaces: May include PROFIBUS DP/MPI interfaces depending on the individual CPU module specifications.

• Power Supply:

• Included: 2 x PS407 UC, supporting 120/230V AC, 10 A each, ensuring redundancy.

• Range: May vary depending on the power supply specifications but typically suitable for global voltages.

• Additional Hardware:

• 1 x UR2-H: Redundancy unit for automatic CPU switchover.

• 4 x Synchronization Modules: Enables synchronized operation of CPUs, ensuring seamless failover.

• 2 x Synchronization Cables (1m): Connects synchronization modules.

• 4 x Buffer Batteries: Maintains RAM contents during power outages, ensuring retentivity of programs and data.

Memory Configuration

• RAM Capacity: 1 MB per CPU (total 2 MB with redundancy)

• Retentive Memory: Backed up by buffer batteries, ensuring program and data retention in case of power loss.

Programming Environment

• Supported Software: STEP 7 V5.x or higher, depending on the latest compatibility releases.

Processing Capabilities

• Processing power and speed specifications will vary based on the 412-3H CPU model, but generally capable of handling complex automation tasks with high speed and precision.

• Includes fixed-point and floating-point arithmetic operations with similar performance metrics as the S7-300 series but tailored for heavier loads and more demanding applications.

Additional Features

• Program Block Quantities: Maximum number of Data Blocks (DBs), Function Blocks (FBs), Functions (FCs), and Organization Blocks (OBs) will depend on the RAM capacity and STEP 7 limitations but will support extensive automation programs.

• Timers and Counters: Unlimited (limited only by RAM capacity), with retentivity ensured by the buffer batteries.

• Scalability: System can be expanded with additional I/O modules, communication modules, and functional modules as required.

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, particularly for detailed technical specifications and compatibility requirements.
