基于IEC 61131-3标准的控制系统及应用 IEC标准的详细介绍

可编程语言标准IEC61131-3中文版

IEC61131-3中文说明 很详细的说明，对PLC等编程很有帮助。

本书共分7章,主要介绍PLCopen组织和编程语言基本概念、标准编程语言的共用元素和程序组织单元、指令表和结构化文本的文本类编程语言、梯形图和功能块图的图形类编程语言、顺序功能表图编程语言和可编程控制器的基本应用，最后并用两个实例说明，可编程控制器的编程方法和注意事项。 编程语言

一篇遵循IEC61131-3与PLCopen标准的嵌入式软PLC应用开发的研究的论文

调用功能块 例子 VAR timer : TOF; out : BOOL; END_VAR timer(IN:= TRUE, PT:= T#1s); ... timer (IN:= FALSE); out := timer.Q; IEC 61131 结构文本 (ST)

iec61131-3一般指IEC 61131-3。IEC 61131-3是由国际电工委员会（IEC）于1993年12月所制定IEC 61131标准的第3部分，用于规范可编程逻辑控制器（PLC），DCS，IPC，CNC和SCADA的编程系统的标准

IEC61131-3国家标准中编程语言部分，适合开发者参考

The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
