The Siemens 6ES7 315-2AG10-0AB0 CPU module is a CPU315-2 DP central processing unit for the SIMATIC S7-300 family, featuring an integrated PROFIBUS DP interface for fieldbus communications. It is designed to execute control programs and coordinate communications with DP devices, I/O, and drives over Profibus DP in mid‑range automation applications. As an older S7-300 part, it is commonly found as a spare or used module, with Siemens offering an upgrade path to the 6ES7 315-2AH14-0AB0 family. Programming and configuration are performed with Siemens STEP 7 software within the SIMATIC S7‑300 ecosystem.
