This document introduces the features and characteristics of the Siemens S7-1200 series programmable controllers and their related modules. The S7-1200 has integrated PROFINET interface, powerful integrated process functions, and flexible scalability. It is suitable for medium and small automation systems, and emphasizes the integration and coordination of systems, controllers, human-machine interfaces, and software.
The SIMATIC S7-1200 series is a compact, modular PLC family designed for small‑to‑medium automation tasks. It offers integrated PROFINET communication, flexible I/O expansion, and a range of CPU, signal, power and communication modules that can be mounted on standard 35 mm DIN rails.
The document lists detailed technical data for each CPU model, including dimensions, power consumption, memory sizes, I/O counts, and voltage ranges, as well as ordering numbers and certification information. Appendices provide wiring diagrams, general technical specifications, and ordering data. This manual is written in Chinese.
