基于iec61131-3标准的嵌入式控制系统的设计与实现based on iec61131-3 standard of the design and implementation of an embedded control system.docx

are put forwarded. Then,the CoDeSys software is selected as programming system ,and the functions and features of the progr缸m旧ng sy如m and CoDeSys sp
core are introduced. The paper discusses the achieve scheme of real-time multitasking operating system,and particularly designs and put forwarded three kinds of achieve
methods of the runtime system and finally achieve it based on CoDeSys sp ∞re. Lastly,
The paper constructs the hardware pJatform of controlled system with the breadboard using S3C2410 microprocessor and L时UX OS,achieves munication between the Oper创ing sys始m and runtime system,and between runtÎme system and peripher a1
devices.
