Description
Description
The Siemens 6ES7315-2EH13-0AB0 is a high-performance Central Processing Unit (CPU) designed for the SIMATIC S7-300 automation system. This CPU 315-2 PN/DP module provides robust processing power for medium-to-large scale industrial control applications. It features 256 KB of integrated working memory and supports dual-interface communication, allowing for seamless integration into complex network architectures. Please note that this specific model has been superseded by the 6ES7315-2EH14-0AB0.
Features
- Integrated 256 KB working memory for program and data storage.
- Dual interface capability: MPI/DP (up to 12 Mbit/s) and Ethernet PROFINET.
- Requires a Micro Memory Card (MMC) for operation.
- Supports advanced industrial communication protocols for distributed I/O and HMI connectivity.
- Compact design suitable for standard S7-300 rail mounting.
Applications
This CPU is widely utilized in manufacturing, process automation, and infrastructure control systems where reliable PLC performance and PROFINET connectivity are required. It is ideal for managing distributed I/O stations, motion control tasks, and data exchange between plant-floor controllers and higher-level management systems.

Installation Guidelines
- Ensure the CPU is mounted on a standard 35mm DIN rail and secured properly within the S7-300 rack.
- Always power down the system before inserting or removing the CPU or any communication modules to prevent electrical arcing or damage to the backplane.
- Use shielded cables for PROFINET and PROFIBUS connections to minimize EMI interference in industrial environments.
- Ensure the 24V DC power supply is protected by a minimum 2A external fuse.
- Handle the module using ESD-safe practices to prevent damage to sensitive internal components.
- Verify that the required Micro Memory Card is correctly inserted before attempting to power up the unit.
FAQ
