Siemens 6ES7315-2EH14-0AB0 Programmable Logic Controller CPU Module

Siemens 6ES7315-2EH14-0AB0 is a SIMATIC S7-300 CPU 315-2 PN/DP central processing unit designed for the S7-300 family. The module exposes 384 KB of working memory for logic and data handling and provides two network interfaces: a first MPI/DP interface at 12 Mbps for classic fieldbus communication and a second Ethernet PROFINET interface that includes a built-in two-port switch for IP-based control networks. A Micro Memory Card (MMC) is required to store programs and data. As a PN/DP capable CPU, it supports integration with PROFIBUS DP devices and PROFINET networks, enabling distributed I/O and PLC-to-PLC communication within industrial automation cabinets and machines using the S7-300 platform. The 315-2 PN/DP variant is intended for mid-range control tasks in automation projects, combining deterministic PLC processing with dual-network connectivity in a compact CPU module.
