Siemens AG 6ES7 315-2AG10-0AB0 Programmable Logic Controller

Siemens 6ES7315-2AG10-0AB0, also listed as 6ES7 315-2AG10-0AB0, is a SIMATIC S7-300 CPU designed for older automation projects requiring a DP-capable controller. The CPU 315-2DP provides a Profibus DP interface for communicating with distributed I/O and field devices within a SIMATIC S7-300 rack-based system and runs on a 24 V DC power supply. Firmware revisions cited in Siemens literature include V2.0 and V2.6, reflecting variations across production lots. Siemens notes that this module is part of an older generation and has been superseded in current catalogs by the 6ES7 315-2AH14-0AB0, making it a discontinued spare part in many markets. In practice, the 315-2DP variant is used to run classic STEP 7/Simatic Manager projects and connect with DP devices in compact automation tasks, offering a familiar, durable solution for established S7-300 installations.
