Siemens SIMATIC S7-400H, CPU 414H 6ES7414-4HJ04-0AB0

Specification Sheet for Siemens SIMATIC S7-400H, CPU 414H - 6ES7414-4HJ04-0AB0

Basic Information

• Product Model: 6ES7414-4HJ04-0AB0

• Product Series: SIMATIC S7-400H

• CPU Type: CPU 414H

• Application Areas: Chemical, Electronics, Electrical, and other critical industrial automation fields requiring high availability and redundancy

Hardware Characteristics

• Integrated Interfaces:

• 1 MPI/DP interface

• 1 PROFIBUS DP interface

• 2 Interfaces for synchronization modules

• Power Supply: Typically requires external 24 V DC, with voltage range specified by Siemens for the specific model

• Power Protection: External protection highly recommended (for power supply cables and system as a whole)

• Redundancy: Supports hot-standby redundancy (S7-400H) or fault-tolerant systems (S7-400F/FH)

Memory Configuration

• Total Memory: 1.4 MB

• Data Memory: 700 KB

• Program Memory: 700 KB

• Load Memory: Additional memory can be expanded through external storage devices or modules as per system configuration

Programming Environment

• Supported Software: STEP 7 V5.x or higher, depending on specific version and updates

• Configuration Tools: TIA Portal (if supported by version) or classic STEP 7 software

Processing Capabilities

• Processing speed and arithmetic operation times will vary based on the specific model and application load, but generally expected to be higher than the S7-300 series due to the higher-end hardware.

• Capable of handling complex control algorithms and large program sizes

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs), Function Blocks (FBs), and Functions (FCs) will depend on the total memory capacity and may be expanded through external modules.

• Types and quantities of Organization Blocks (OBs) include OB1 (main program loop), OB8x (fault handling), OB100/101/102 (startup), and others as per Siemens' documentation.

• Counters and Timers:

• S7 Counters and Timers are unlimited, practically speaking, as they are limited only by the available RAM capacity. Retentivity is supported for both counters and timers.

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, especially regarding specific memory capacities, processing speeds, and compatibility with different software versions.

• When considering S7-400H systems, be aware of the additional requirements and configuration steps for setting up redundancy and fault tolerance.
