PLC可编程控制器教学仿真软件的开发

On the exploitation of PLC programmable logical controllers simulated software for education

阐述了如何利用计算机仿真技术，开发一种硬件要求低、可移植性好，适用于教学需要的ＰＬＣ可编程控制器仿真软件．使学生在计算机虚拟的ＰＬＣ环境下，练习ＰＬＣ编程技术，从而解决了ＰＬＣ实验组织困难的一系列实际问题．

The paper explains how to make use of computer simulation technology to develop PCL programmable controller simulated software suitable for teaching with the features of low requirement for hardware and Rood quality oftransplantation. The students will be able to practice PLC programming technology in the computer virtual environment and a series of problems concerning organizing PLC experiments are therefore solved.
