功能块图(Function Block Diagram, FBD) 指令表(Instruction List, IL) 顺序功能图(Sequential Function Chart, SFC) 结构化文本(Structured Text, ST) ST语言的设计初衷 梯形图的局限性 ST语言的设计初衷与梯形图(Ladder Diagram, LD)有一定的关联,它们的定位和目标也有所不同。 梯形图是一种图形化编程语言,起...
A. Ladder Diagram B. Function Block Diagram C. Structured Text D. Sequential Function Chart 相关知识点: 试题来源: 解析 A、B、C、D 答案:A、B、C、D 解析:PLC的常见编程语言包括Ladder Diagram(梯形图)、Function Block Diagram(功能块图)、Structured Text(结构化文本)和Sequential Function Chart(顺序...
This text can be structured by dividing it into sections. These sections represent logical units of an ST source. These sections can be:: a program that is assigned to a runtime level, a class with its subordinate methods, a function block with its own memory, or a function without its ...
Use thesimplestlogic you possibly can (not the shortest). If the machine you’re programming has 10 motors, don’t try to write the motor start/stop logic in Structured Text with aFORloop. Don’t even make a function block and re-use it 10 times. Just write 10 different programs in ...
模块化编程是StructuredText中的一个重要特性,可以将复杂的程序分解为多个可重用的模块。以下是一个简单的模块化编程示例。 3.5.1模块化示例 假设我们需要编写一个温度控制模块,该模块包含温度读取、PID控制和电机控制。 3.5.1.1温度读取模块 FUNCTION_BLOCKTemperatureSensor VAR_OUTPUT fTemperature:REAL;//读取的温度 ...
The poST language is a process-oriented extension of the IEC 61131-3 Structured Text (ST) language. The language targets specifying stateful behavior of PLC-based control software. The main purpose of our contribution is to provide coherence of the PLC source code with technological description of...
Structured Text is PLC programming language defined byPLCOpeninIEC 61131-3. The programming language is text-based, compared to the graphics-based ladder diagram orFunction Block Diagram. At first, it may seem better to use a graphical programming language for PLC programming. But in my opinion...
END_FUNCTION_BLOCK; If the testing of volts 1, volts 2, or volts 3 indicates that any one of them is more than 12, the output OVERVOLTS is set to true and the RETURN statement called to terminate the execution of the function block. In the rest of the program, when OVERVOLTS is se...
