摘要
在自动化工程项目中使用PLC作为控制手段已经是很平常的事了 ,在工程开发前期控制装置定型之前向客户展示控制装置的功能 ,不仅对客户而且对开发者都是有积极意义的 ,这种展示需要一套适当的被控对象的模型。本文详细介绍了制作这种计算机仿真对象的思路和具体方法 。
A kind of computer simulation for PLC is introduced in this paper.The moving pictures of object are programmed in C language.The messages are transferred to I/O port of PLC through a parallel I/O card.It is not only good in real-time but also compatible for all kinds of PLC.The idea and method are described in detail and key program is given too.
