The Siemens 6ES7315-2EH14-0AB0 is a SIMATIC S7-300 CPU module (315-2 PN/DP) designed as the central processing unit for S7-300 automation systems. It includes 384 KB of working memory, enabling moderate program and data handling for PLC tasks. The CPU provides two communication interfaces: a first MPI/DP interface at 12 Mbit/s for standard fieldbus networking and a second Ethernet PROFINET interface with a built-in 2-port switch for industrial Ethernet connectivity. A Micro Memory Card is required for operation.
