SIEMENS 6ES7315-2AH14-0AB0 Used Working SIMATIC S7-300 PLC CPU

Product Overview

The Siemens 6ES7315-2AH14-0AB0 is a highly versatile CPU 315-2 DP for the SIMATIC S7-300 modular PLC system. This CPU is a mainstay in mid-to-large scale automation, offering a perfect balance between processing power and memory capacity. It features an integrated PROFIBUS DP interface, allowing it to act as both a master and a slave in a decentralized I/O network. This Used Working unit is ideal for high-speed machine control, manufacturing plants, and complex processing tasks where robust communication and reliable performance are required.

Key Features

• Dual Interface Ports: Equipped with one MPI (Multi-Point Interface) and one high-speed PROFIBUS DP interface (up to 12 Mbit/s).
• Expanded Memory: Features 256 KB of integrated work memory, capable of handling medium-to-large program structures and data blocks.
• Profibus Master/Slave: Can manage up to 124 PROFIBUS DP slaves, making it the heart of a distributed automation network.
• Micro Memory Card (MMC) Support: Uses a Siemens MMC for retentive data storage and easy program backup/transfer (required for operation).
• High-Speed Processing: Fast command execution times for efficient handling of bit and floating-point arithmetic.
• Comprehensive Instruction Set: Supports Ladder (LAD), Function Block Diagram (FBD), and Statement List (STL) programming via STEP 7 or TIA Portal.
• Modular Expandability: Supports up to 32 modules across 4 racks via the backplane bus.

Item Condition (Used - Working)

• Functional Status: Used - Working. This CPU has been professionally tested in a SIMATIC rack. It successfully enters "RUN" mode, communicates via both MPI and PROFIBUS ports, and has been cleared of any previous password protection/logic.
• Physical State: Excellent condition. The front hinged cover is intact and snaps shut securely. The backplane bus pins are straight and clean.
• Technical Integrity: No "SF" (System Fault) or "BF" (Bus Fault) hardware errors detected during diagnostic testing. The mode selector switch (RUN/STOP/MRES) is fully functional.
• Visual Reference: Please examine the high-resolution images to verify the Hardware (E-Stand) and Firmware versions; the unit pictured is the exact 6ES7315-2AH14-0AB0 you will receive.
