摘要
针对目前普通PLC存在的一些不足,采用PHILIPS公司的ARM微处理器LPC2294和嵌入式操作系统μCOS-Ⅱ,面向工业控制领域设计了一种嵌入式PLC。阐述了该嵌入式PLC的硬件设计电路及软件系统。源代码开放的μCOS-II操作系统在该处理器上的移植提高了系统的可靠性,提高了软件开发效率,缩短了开发周期。用户编程界面采用了符合IEC61131-3编程语言标准的SWOPC-FXGP/WIN-C编程环境。所设计的嵌入式PLC功能灵活,易于剪裁,更贴近各种档次的机电设备的控制要求。
In view of the deficiencies of present ordinary PLC, using PHILIPS company ARM microprocessors LPC2294 and embedded operating system t,C/OS--II, this paper designed an embedded PLC for the field of industrial control. The paper elaborated the embedded PLC hardware circuit design and the software system. The processors transplant of μC/OS--II operating system, which has opening source code, improved the reliability of the system, improved the efficiency of software development, and shortened the development cycle. User＇s programming interface adopted the SWOPC--FXGP/WIN--C environment, which has the 1EC61131- 3 programming language standard. The designed embedded PLC has advantages of flexible functions, convenient, closer to the various grades of electrical and mechanical equip nlent requirements.
