编程器是PC用户编制应用软件时实现人机对话的必备工具,它是与可编程序控制器主机相配套的外部设备,故其外形尺寸、主要功能、显示方式和键入操作是否配置合理、完善齐全、形象直观和使用简便,将影响用户的使用和用户程序的开发过程。 编程器产品型号较多、品种不一,本文仅从小型低功耗、价廉又实用的角度出发,就某型可手持LCD编程器的外形、功能、屏幕和键盘等特点作一初步介绍。
PC programmer is the necessary tool to realize the man-machine dialogue when the PC user compiles the application software. It is an external device matching with the host computer of the programmable logic controller. Therefore, its appearance size, main function, display mode and key-in operation are configured rationally, Perfect complete, intuitive image and easy to use, will affect the user’s use and user program development process. More programmer product models, different varieties, this article only from the small low-power, low cost and practical point of view, on a type of handheld LCD programmer shape, function, screen and keyboard for a preliminary introduction.
