摘要
阐述了一种以新型PLC装置为基础的手持编程器的设计,重点描述了编程器核心模块的结构和软件设计方法。编程器以CAN作为主通讯接口,ARM7为控制器,构建了uC/OS-Ⅱ内核的实时操作系统;实现了远距离编程、监控、调试PLC控制系统,脱机编程及直接与计算机交换数据的功能,适合工业现场使用。
The paper introduces the method for the design of the PLC hand-held programmer based on a new type of PLC device.It particularly describes the design method of the structure and software on core modules.The CAN bus is used as a main way of communication.The ARM7 chip is selected as the main controller.The RTOS on uC/Ⅱ is built.The instrument realizes the function of remote monitoring,programing and adjusting the PLC device,and programming in off-line model.It can communicate with the computer directly and will be suitable for the industry field.
