The sample presents technical features, modules, installation guidance, communication options, and ordering data for the Siemens S7-1200 programmable…
The SIMATIC S7-1200 series is a compact, modular programmable controller family that integrates a PROFINET interface, powerful process functions and flexible expandability for small‑to‑medium automation tasks. It offers a range of CPU modules, signal and I/O extension modules, and communication options that can be mixed to suit specific applications.
The document details hardware dimensions, environmental limits, EMC compliance, memory capacities, high‑speed counter capabilities, and provides ordering numbers for each module. It also lists supported communication protocols such as PROFINET, PROFIBUS, Modbus RTU, GPRS and USS, and references the TIA engineering software platform for configuration and programming. This manual is written in Chinese.
