Features:

  • Interface Between the Universal AC Power Source and SIMATIC S7-300 Rack Backplane
  • Combines Capability of AC/DC Power Conversion with Integrated 24V DC Power Supply
  • Operates in Conjunction with the S7-300 Signal Modules and Distributed I/O Devices
The Siemens 6ES7314-6EH04-0AB0 Compact CPU operates as the central processing unit in a SIMATIC S7-300 rack, providing reliable control and integrated power distribution to all modules within the system. It continuously processes control logic through its 192 Kbyte working memory while converting incoming 24 VDC power through its integrated power supply to support steady state operation of all monitors and modules. Seamless communication is standard with the 6ES7314-6EH04-0AB0, however using its dual interface architecture will allow seamless switchover between MPI/DP and PROFINET networks in the event of a primary communication path failure. The 6ES7314-6EH04-0AB0 has made improvements in several areas over previous CPU designs in addition to incorporating universal communication capability within the S7-300 rack.

The 6ES7314-6EH04-0AB0 provides essential control functions common to the entire rack, and is a critical component of the automation path, directly affecting the proper, normal operation of the overall control system. One 6ES7314-6EH04-0AB0 CPU is required per rack depending on the desired processing capability. The 6ES7314-6EH04-0AB0 occupies a standard slot in the rack and is always located in the designated CPU position.

For Dual Network Communication applications, the S7-300 System utilizes the second interface of the 6ES7314-6EH04-0AB0 CPU module equipped with Ethernet PROFINET and 2-port switch. In addition to standard single network operation, the redundant configuration also performs automatic protocol bridging. The 6ES7314-6EH04-0AB0 dual interface configuration executes failover using the internal circuitry specified in the communication options. Using this method, the redundant communication system continually monitors the health of both networks. If the system detects that the primary PROFINET connection is no longer providing stable data exchange (outside configured timeout/tolerance levels), it will automatically transfer the load to the secondary MPI/DP interface and place an event in the diagnostic buffer.

The 6ES7314-6EH04-0AB0 Siemens Compact CPU may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Siemens 6ES7314-6EH04-0AB0 is a SIMATIC S7-300 CPU 314C-2PN/DP compact CPU designed for industrial automation applications requiring integrated control, communication, and process interfacing capabilities. This 6ES7314-6EH04-0AB0 processor features 192 KB of working memory and combines a rich onboard I/O set with dual communication interfaces, making the 6ES7314-6EH04-0AB0 particularly suitable for machine builders and system integrators who need a space-efficient yet powerful controller for mid-range automation tasks. The 6ES7314-6EH04-0AB0 is equipped with 24 digital inputs and 16 digital outputs, 4 analog inputs and 2 analog outputs, plus 1 Pt100 temperature input channel, allowing the 6ES7314-6EH04-0AB0 to handle mixed-signal environments without requiring additional signal modules.

This 6ES7314-6EH04-0AB0 is further distinguished by its inclusion of 4 fast counters operating at 60 kHz, enabling the 6ES7314-6EH04-0AB0 to perform high-speed counting, positioning, and frequency measurement tasks directly at the CPU level. The 6ES7314-6EH04-0AB0 features two integrated communication interfaces: the first is an MPI/DP interface supporting up to 12 Mbit/s for connection to programming devices, operator panels, or PROFIBUS networks, while the second is an Ethernet PROFINET interface equipped with a 2-port switch. This PROFINET capability allows the 6ES7314-6EH04-0AB0 to serve as a compact IO-Controller or IO-Device in distributed automation architectures, facilitating real-time data exchange with PROFINET-compatible I/O modules, drives, and HMI systems while supporting line topology through the integrated switch.

The 6ES7314-6EH04-0AB0 includes an integrated 24 V DC power supply, simplifying cabinet wiring and reducing the need for external power modules. This 6ES7314-6EH04-0AB0 requires a front connector (2 x 40-pin) and a micro memory card for operation, ensuring program and data retention. This compact CPU, the 6ES7314-6EH04-0AB0, is specifically designed for applications such as packaging machinery, conveyor systems, process control skids, and assembly stations where space is limited but multiprotocol communication and high-speed counting are essential. The 6ES7314-6EH04-0AB0 addresses the challenge of reducing hardware footprint while maintaining connectivity flexibility, as its built-in PROFINET switch and MPI/DP port eliminate the need for separate communication processors, and its onboard analog and digital I/O reduce the module count in the rack. By integrating these functions, the 6ES7314-6EH04-0AB0 solves the problem of complex wiring and excessive cabinet space usage, providing a streamlined solution for OEMs and end-users seeking a cost-effective, all-in-one controller for distributed and centralized automation systems.
