Siemens 6ES7315-1AF01-0AB0 Programmable Logic Controller

Siemens 6ES7315-1AF01-0AB0 is a SIMATIC S7-300 CPU 315 with an integrated 24 V DC power supply and 48 KB of working memory. This CPU315 module functions as the central processing unit in a SIMATIC S7-300 controller, executing user programs, handling I/O scanning, and coordinating control logic within compact PLC installations; it is used within the Siemens STEP 7 programming environment as part of a complete automation solution. The built-in 24 V DC supply simplifies cabinet layout by removing the need for a separate power module, while the 48 KB RAM supports moderate program size and data handling typical of small to medium control tasks. The 6ES7315-1AF01-0AB0 designation identifies a specific integrated-power-supply variant in the CPU 315 family, designed to slot into standard S7-300 systems alongside compatible I/O and communication modules. In legacy projects that use the S7-300 architecture, this CPU can be used within existing control configurations with appropriate module support.
