Specification

The SIEMENS SIMATIC S7-300, CPU 317F-2DP (6ES7317-6FF00-0AB0) is a sophisticated failsafe CPU engineered for high-integrity automation systems. It excels in industries like chemical processing, electronics manufacturing, and electrical power distribution, where both high-speed logic and safety-critical functions are paramount. This CPU integrates two Profibus DP interfaces—one MPI/DP and one dedicated DP—enabling seamless communication with distributed I/O and other DP devices. Its 512 KB working memory supports large-scale programs and data handling, while the optional Distributed Safety software package allows for the implementation of safety functions up to SIL 3 according to IEC 61508. The CPU is powered by a 24 V DC supply and requires a Micro Memory Card (MMC) for program storage, ensuring reliable operation in harsh industrial environments.
