PC-E984-685   可编程控制器 

在SoMachine编程环境下，从SoMachine 软件平台的安装与注册开始逐步进行介绍，中间涉及了软件平台的常用设置选项以及其含义;针对不同项目之间不同控制器的程序转换也做了详尽的介绍与实现方法;以SoMachine 软件平台为基础，详细讲解了控制器的通讯连接、变表的定义与应用、程序组织单元(POU)的定义与应用、物理地址的定义与应用等这些常规的基础知识，从初的基础应用开始，慢慢引导进入项目的实际编程工作中去。
02SoMachine软件平台的编程方法是基于IEC61131标准的，使设计人员对机器控制的设计和编程不局限在-种编程方式，也不拘泥于只对逻辑状态进行编程。可以根据工艺要求而采用顺序流程图(SFC) 的方式规划结构，采用结构文本(ST) 的方式进行复杂工艺运算和调节计算,采用梯形图(LD)的方式处理各种逻辑和工艺过程，采用功能块图(FBD) 的方式进行同-功能的反复调用和对通讯功能、轴控功能的搭建。
03在基础以及课程中，针对编程方面，详细介绍了各种编程语言的优势以及使用方法，基本编程指令的应用，功能块的定义与应用,结构体的定义与应用等;在实际应用方面，常用的读取与设置PLC的时钟、串口的配置与各种应用，如何添加第三方设备以及常见故障处理、编程技巧、库文件及曲线记录功能的应用、网络以及总线通讯、高速计数与高速脉冲输出等也都一 一做了详尽的讲解。

In the SoMachine programming environment, the installation and registration of the SoMachine software platform will be introduced step by step, and the commonly used setting options and their meanings of the software platform will be covered in the middle; A detailed introduction and implementation method were also provided for the program conversion of different controllers between different projects; Based on the SoMachine software platform, this article provides a detailed explanation of the communication connection of the controller, the definition and application of variable tables, the definition and application of program organization units (POUs), the definition and application of physical addresses, and other conventional basic knowledge. Starting from the initial basic application, it gradually guides into the actual programming work of the project.
The programming method of the 02SoMachine software platform is based on the IEC61131 standard, allowing designers to design and program machine control beyond just one programming method and not limited to programming only logical states. According to process requirements, the structure can be planned using Sequential Flow Chart (SFC), complex process operations and adjustment calculations can be carried out using Structural Text (ST), various logic and process processes can be processed using Ladder Diagram (LD), and the same function can be repeatedly called and communication and axis control functions can be built using Function Block Diagram (FBD).
In the basic and advanced courses, the advantages and usage methods of various programming languages, the application of basic programming instructions, the definition and application of functional blocks, and the definition and application of structural entities were introduced in detail in the field of programming; In practical applications, the commonly used methods of reading and setting PLC clocks, configuring serial ports, and various applications, as well as how to add third-party devices, common fault handling, programming techniques, application of library files and curve recording functions, network and bus communication, high-speed counting and high-speed pulse output, etc., have also been explained in detail.
