Siemens 6ES7317-2EK14-0AB0 SIMATIC S7-300 CPU
The Siemens 6ES7317-2EK14-0AB0 is a SIMATIC S7-300 CPU 317-2 PN/DP, a higher-performance modular CPU in the S7-300 family, combining PROFINET and PROFIBUS DP communication in one unit. It’s built for larger or more complex S7-300-based systems that need more memory, I/O capacity, and processing speed than the 315-2 PN/DP can offer. As a modular CPU, it mounts on an S7-300 rack alongside a separate power supply module and I/O modules to form a complete working system.

Description
The Siemens SIMATIC S7-300 CPU 317-2 PN/DP offers 1 MB of integrated work memory, giving it significantly more capacity than the 315-2 PN/DP for larger or more complex control programs. It runs on a 24V DC supply and includes a combined MPI/PROFIBUS DP interface alongside a separate PROFINET interface with a 2-port switch, allowing it to communicate with both legacy fieldbus devices and modern Ethernet-based equipment simultaneously. A Micro Memory Card (MMC) is required to store the program and retain data without a battery.
This CPU is programmed using STEP 7 (V5.5 or higher) and supports LAD, FBD, STL, SCL, CFC, GRAPH, and HiGraph programming languages. It supports both PROFINET IO Controller and IO Device functionality at the same time, along with media redundancy for network resilience. With a larger I/O address area and higher digital and analog channel counts than the 315-2 PN/DP, it’s better suited for systems with more field devices to manage.
