Specification Sheet for Siemens SIMATIC S7-400H, CPU 414-4H PG (6ES7414-4HR14-0AB0)

Basic Information

• Product Model: 6ES7414-4HR14-0AB0

• Product Series: SIMATIC S7-400H

• CPU Type: CPU 414-4H PG

• Application Areas: Suitable for high-end, mission-critical, and fault-tolerant automation solutions in industries such as Process Control, Power Generation, and other industrial sectors requiring high availability.

Hardware Characteristics

• Integrated Interfaces:

• 1 MPI/DP interface for communication with programming devices and HMI systems

• 1 DP interface for high-speed communication with other SIMATIC DP devices

• 2 interfaces for synchronization modules (for redundancy purposes)

• Power Supply: Typically requires an external 24 V DC power supply with specific requirements as per Siemens specifications

• Power Protection: External protection measures recommended for power supply cables and the system as a whole to ensure high availability

Memory Configuration

• Total Memory: 12 MB

• Data Memory: 10 MB, dedicated for storing process data and configuration settings

• Program Memory: 2 MB, for storing the control program and logic

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher, providing comprehensive programming, configuration, and diagnosis tools for SIMATIC S7 controllers

Processing Capabilities

• The CPU 414-4H PG is designed for high-performance applications, offering fast processing speeds suitable for complex control strategies and real-time operations.

• Specific bit, word, fixed-point, and floating-point arithmetic operation times are typically faster than the S7-300 series, but may vary depending on the actual application and load on the CPU.

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs): Configurable based on available memory, suitable for storing large amounts of process data

• Maximum number of Function Blocks (FBs) and Functions (FCs): Configurable, with the ability to handle complex control logic

• Types and quantities of Organization Blocks (OBs): Comprehensive set of OBs, including those for cyclic tasks (OB1), interrupts, faults, and start-up/shutdown routines, to cater to various control needs

• Counters and Timers:

• S7 Counters and Timers: Unlimited in number (limited only by RAM capacity), with retentivity to ensure that count and timer values are preserved across power cycles

• Redundancy and High Availability: As part of the S7-400H system, the CPU 414-4H PG supports redundant configurations, enabling seamless failover in case of a hardware failure, ensuring continuous operation of critical processes.
