Specification Sheet for Siemens SIMATIC S7-400, CPU 414-2 - 6ES7414-2XK05-0AB0
Basic Information
Product Model: 6ES7414-2XK05-0AB0
Product Series: SIMATIC S7-400
CPU Type: CPU 414-2
Application Areas: Chemical, Electronics, Electrical, and other industrial automation fields requiring high-performance processing capabilities
Hardware Characteristics
Integrated Interfaces:
1st Interface: MPI/DP, supporting up to 12 Mbit/s
2nd Interface: PROFIBUS DP, supporting standard PROFIBUS DP communication protocols
Power Supply: Typically requires external 24 V DC, with voltage range specified by Siemens for the specific model
Power Protection: External protection recommended (for power supply cables and system as a whole)
Memory Configuration
Work Memory: 1 MB, divided into:
0.5 MB for Code (Program Memory)
0.5 MB for Data (Data 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
High-performance CPU designed for complex control algorithms and large program sizes
Processing speed and arithmetic operation times will vary based on the specific model and application load, but generally expected to be significantly faster than the S7-300 series
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 configuring the CPU 414-2, consider the communication requirements and ensure that the selected interfaces (MPI/DP and PROFIBUS DP) meet the needs of the automation system.
