The S7-200CN is the “mainframe” for Siemens’s line of micro-programmable logic controllers (Micro PLCs) for controlling a variety of automation applications. The system is modular and can be fitted with any of five CPUs, from simple to high-performance, each suited to different levels of system and process complexity. Programming is done via a Windows-based tool.
The CN version was developed specifically for the China market, although the S7-200 PLC has been a mainstay in that market since its introduction there in 1994. The S7-200 product line has been repeatedly redesigned since its introduction to be smaller, faster, and to have increased functionality. The new S7-200 products are drop-in replacements for previous versions.
