【摘要】 介绍了自行开发的新型PLC系统。其中包含软件集成开发环境,以及以Cygnal公司高性能CPU—C8051F为核心的硬件系统。由于该芯片内部集成了多种接口,简化了PLC硬件结构。系统的软件开发环境遵循IEC61131-3标准,支持多种PLC语言开发,集成了编辑、编译连接、下载和调试等功能,方便了用户对PLC的开发和使用。更多还原

【Abstract】 This paper introduces the idea embodied in the design of a new type PLC that are developed by the authors. In the design, C8051F from Cygnal Company is used. C8051F is a high-speed, 8051-compatible micro-controller integrated with enough interfaces. This character of C8051F simplifies the hardware structure of PLC. At the same time, an Integrated Development Environment (IDE) for PLC is developed. Based on the PLC Programming Language Standard IEC6113-3, the IDE makes the development of PLC feasible.更多还原
