Siemens 6ES7 316-2AG00-0AB0 Programmable Logic Controller

Siemens 6ES7 316-2AG00-0AB0 is a CPU module in the SIMATIC S7-300 family designed for compact, DP-enabled automation tasks. Identified as CPU 316-2 DP, it includes an integrated MPI/PROFIBUS DP interface that can operate as a PROFIBUS DP master or slave and supports fast bit-level communications with up to 0.6 µs for DP bit operations. The unit provides 128 KB of RAM for program and data storage and expects a 24 V DC power supply, drawing roughly 0.9 A under typical load. As part of the S7-300 modular controller lineup, this CPU handles ladder logic or structured text programs, I/O interfacing, and communications with DP devices and remote I/O blocks, enabling centralized or distributed control in small to mid-size automation cells. Typical applications include machine controls, packaging lines, conveyors, and other production equipment that rely on PROFIBUS DP networking for device coordination and status reporting. The 6ES7 316-2AG00-0AB0 is designed to drop into an S7-300 rack backplane and be configured with STEP 7 engineering software for sequence control, data exchange, and timing-critical control tasks, making it a practical choice when a compact, DP-capable CPU is required for proven Siemens automation ecosystems.
