Siemens 6ES7317-2FK14-0AB0 CPU Module SIMATIC S7-300

Siemens 6ES7317-2FK14-0AB0 CPU Module, part of the SIMATIC S7-300 family, is the central processing unit for a modular rack-based PLC system. It corresponds to the CPU 317F-2 PN/DP variant and executes ladder logic and other control programs while managing both DP and PN communications, enabling compact automation designs with built-in multi-network connectivity. The module provides 1 MB of working memory for runtime and user data and combines two communications interfaces: a 12 Mbit/s MPI/DP interface for PROFIBUS DP networks and an Ethernet PROFINET interface with a two-port switch for PLC-to-PLC or device-to-device networking. Designed for insertion into an S7-300 rack, this CPU supports scalable automation architectures that rely on distributed I/O and integrated PN/DP connectivity, making it suitable for applications such as machine control, packaging lines, and small production cells where reliable CPU performance and network communication are essential.
