基于Multisim 9.0的PLC案例设计与仿真

Design and simulation of PLC case based on Multisim 9. 0

简述Multisim 9.0仿真软件的功能与特点。以传送带控制系统的设计与仿真为例,介绍传送带控制系统的硬件设计、硬件连接、顺序功能图的设计、梯形图的编写及整体电路的仿真过程。利用该软件可以随时随地进行PLC设计仿真。

Functions and characteristics of the Multisim 9.0 simulation soitware are briefly introduced. Taking the design and simulation of the conveyor belt operating system for example, this thesis introduces the hardware design, hardware connection and SFC, LAD program and the simulation programme of the whole circuit. Such a software can be used to make a design and simulation of PLC whenever and wherever possible.
