2016年4月12日 · IEC-1131 is the first international standard for process control software. By using IEC-1131, a programmer can develop a control algorithm for a particular brand of controller, and import that same program to another brand with minimum modifications, primarily to process input/output subsystems.

IEC 61131 is an IEC standard for programmable controllers. It was first published in 1993; [1] the current (third) edition dates from 2013. [2] It was known as IEC 1131 before the change in numbering system by IEC.

IEC 1131-3-the international standard for programmable controller languages-has achieved this by applying modern software engineering principles to the best existing practices and, at the same time, providing for "extensibility", i.e. further enhancements by vendors. The author describes the development and benefits of IEC 1131-3.

iec 1131-3标准包括两部分：编程和公共元素。编程部分描述了两个重要模型：iec 软件模型和通讯模型。公共元素定义了编程系统中需要的的数据类型。 一、 iec 1131-3的两个重要模型 iec 1131-3标准有两个模型：iec 软件模型和通讯模型。

This revised edition includes all IEC proposed amendments and corrections for the planned 1999 revision of IEC 1131-3, as agreed by the IEC working group. It accurately describes the languages and concepts, and interprets the standard for …

The suitability of each language for solving different types of industrial control problems is described along with techniques and examples. Facilities in the IEC 1131-3 and an accompanying standard IEC 1131-5 for communicating with other PLCs and devices are discussed in Chapter 12, 'Communications'.

IEC 1131-3标准是国际电工委员会（IEC）为工业自动化控制系统软件设计制定的首个标准化编程语言，它独立于任何单一厂商，旨在整合全球PLC厂家的技术和编程语言差异。 该标准由IEC工作组在吸取各厂家精华的基础上创建，它的核心目标是提升软件质量和开发效率，通过图形化和文本语言，简化编程过程，同时方便系统集成商、工程师和最终用户。 IEC 1131-3标准最初针对PLC编程系统，但现在扩展到过程控制、分布式控制系统、控制系统的软逻辑和SCADA等领域，具 …

IEC 1131-3 is the international standard for the design of software for industrial control systems. It defines a set of related graphical and textual languages that bring significant

1997年4月1日 · IEC 1131-3 is a standard for programming languages used in PLCs. It defines a function block diagram language and a type of Grafcet, Sequential Function Charts. An object oriented prototype of these parts has been implemented.

1999年3月30日 · The international standard IEC 1131-3 provides such a tool, dealing with the programming, installation and maintenance phases of software development projects in industrial control. Basically, IEC 1131-3 consists of two parts, i.e. …
