SIEMENS 6ES7314-1AG13-0AB0 Used Working SIMATIC S7-300 PLC CPU

Product Overview

This listing is for a high-performance Siemens SIMATIC S7-300 CPU 314 (6ES7314-1AG13-0AB0) bundled with a genuine 128 KB Micro Memory Card (6ES7953-8LG11-0AA0). The CPU 314 is a standard-setting controller for mid-range automation tasks, known for its compact design and high-speed execution of bit-based and floating-point logic. Unlike the 315-2DP, this unit focuses on localized control via its integrated MPI port. This Used Working bundle provides everything you need to get your logic running immediately, with the included 128 KB MMC offering double the storage capacity of the standard 64 KB card.

Key Features

• Optimized Work Memory: Features 96 KB of integrated work memory for efficient program and data processing.
• 128 KB MMC Included: Comes with the 6ES7953-8LG11-0AA0 Micro Memory Card, providing ample space for program blocks, symbols, and retentive data storage.
• MPI Interface: Built-in Multi-Point Interface (MPI) for high-speed programming, HMI connectivity, and CPU-to-CPU communication (Global Data).
• Fast Command Execution: Designed for rapid bit-logic processing, making it ideal for machine building and material handling systems.
• Modular Versatility: Part of the S7-300 "Classic" range, allowing for a wide variety of digital, analog, and specialty expansion modules.
• Maintenance-Free Data Backup: The included MMC ensures that the program is safely stored without the need for a backup battery.
