Siemens SIMATIC S7-300 CPU317-2 DP (6ES7317-2AK14-0AB0) is a central processing unit for the S7-300 family with 1 MB of working memory, designed for DP communications in industrial control systems. It features an MPI/DP interface at 12 Mbps and a second DP master/slave interface, and requires a Micro Memory Card for program and data storage. Powered from 24 V DC (19.2–28.8 V range), it dissipates about 4.5 W under typical load and is offered as a spare part for projects needing a reliable CPU module with DP networking capabilities and expanded communication options.
