The Siemens SIMATIC S7-300 CPU 314C-2 DP (6ES7314-6CF00-0AB0) is a high-efficiency, all-in-one compact central processing unit engineered for decentralized industrial automation and robust fieldbus networking. Distributed by OUKE, this integrated legacy controller features a 48 KB working memory, an onboard Multi-Point Interface (MPI), and high-density onboard digital and analog I/Os. Supplemented by 4 high-speed counters (10 kHz) and a dedicated PROFIBUS DP master/slave interface, it allows for immediate connection to remote I/O modules, drives, and field devices without the footprint or cost of additional communication processors.
As a highly sought-after component within the mature Siemens S7-300 product ecosystem, this specific CPU 314C-2 DP version serves as a critical spare part for factory maintenance global teams. Sourcing this discontinued compact module from OUKE enables procurement managers to execute direct, drop-in hardware swaps inside established control panels. This immediately eliminates unplanned production downtime and saves your facility from the exorbitant hardware and software migration costs associated with modernizing to newer PLC platforms.
