摘要
以IEC61131-3编程语言规范为基础,通过对软件模型及功能块图的分析,设计了基于IEC61131-3标准的上位机软件,给出了软件的整体架构、功能块库、控制策略编辑、编译和仿真模块的实现方法。通过对控制策略的软仿真,验证了该控制系统上位机软件设计的正确性和可靠性。
In this paper,through the expatiate and analyse about the software model and the function block diagram based on IEC61131-3 specification.This paper design a PC software based on the IEC61131-3 standard,the software is given the structure,function block libraries,edit the control strategy,the compiler and simulation methods module.Through control strategy of the soft simulation,validate that the design of the control system configuration is correctly and effectively.
