Siemens 6ES7317-2EK14-0AB0 Programmable Logic Controller CPU Module

The Siemens 6ES7317-2EK14-0AB0 is a SIMATIC S7-300 CPU 317-2 PN/DP module built for central control in legacy PLC installations. It provides 1 MB of working memory for program and data handling and features two communication paths: an MPI/DP interface at 12 Mbit/s for traditional fieldbus access and a second Ethernet PROFINET interface that includes an integrated 2-port switch for networked device communication. The PN/DP designation indicates support for both PROFINET and DP communications within the same CPU, enabling programming access alongside real-time device networking. A Micro Memory Card is not required for operation. This CPU module is suitable for mid-range automation tasks where a compact footprint and reliable, interconnected control are important.
