Overview
The 6AG1512-1DM03-2AB0 is a Siemens SIPLUS CPU 1512SP-1 PN distributed controller, part of the SIPLUS ET 200SP family for extreme-condition automation. It carries 400 KB of program memory and 2 MB of data memory, with a PROFINET IRT interface featuring a 3-port switch and 25 ns bit performance. The unit is conformal coated and rated for an operating temperature range of -40 °C to 60 °C.
Function & operation
This CPU executes the user program and coordinates distributed I/O on the ET 200SP backplane. The 400 KB program memory and 2 MB data memory size the application — sufficient for medium-complexity machine logic and data handling in a distributed architecture. The PROFINET IRT interface with a 3-port switch enables isochronous real-time communication for motion and high-speed applications, while the 25 ns bit performance supports fast logic evaluation. Conformal coating protects the board against condensation and aggressive atmospheres, extending reliability in cold or humid environments.
Applications
SIPLUS CPUs are specified for automation in harsh environments — refrigerated warehouses, outdoor material handling, food processing washdown zones, and chemical or oil & gas areas where standard electronics would fail. The 6AG1512-1DM03-2AB0 serves as a distributed controller in SIMATIC ET 200SP stations, managing local I/O, drives, and HMIs over PROFINET IRT.
Market & positioning
Within the SIPLUS ET 200SP CPU line, the 1512SP-1 PN sits as a mid-range option with balanced memory and real-time performance. It is based on the standard 6ES7512-1DM03-0AB0 but adds conformal coating and extended temperature range, targeting OEMs and integrators who need a single CPU variant that works across both standard and extreme environments.
