所谓软PLC,实际就是在PC机的平台上,在Windows操纵环境下,用软件来实现PLC的功能,也就是说,软PLC是一种基于PC机开发结构的控制系统,它具有硬PLC的功能、可靠性、速度、故障查找等方面的特点,利用软件技术可以将标准的产业PC转换全功能的PLC过程控制器。软PLC综合了计算机和PLC的开关量控制、模拟量控制、数学运算、数值处理、网络通讯等功能,通过一个多任务控制内核,提供强大的指令集、快速而正确的扫描周期,可靠的操纵和可连接各种I/O系统及网络的开放式结构。软PLC具有硬PLC的功能,同时又提供了PC机环境的各种优点。GEFanuc公司推出了一种外形类似笔记本电脑的PC以Windows为操纵系统,可实现PLC的CPU模块的功能,通过以太网和I/O模块、通讯模块用于工厂的现场控制。在美国底特律汽车城,大多数汽车装配自动生产线、热处理工艺生产线等都已由传统PLC控制改为软件PLC控制,可以说,高性能价格比的软PLC将成为今后高档PLC的发展方向。5、PLC编程语言趋于标准化

IEC61131是可编程控制器的国际标准,共有8个部分,从1992年开始陆续颁布实行。IEC61131-3是PLC编程语言的标准,于1993年颁布实施。
IEC61131-8于2001年颁布实施,与IEC61131-3被称为PLC语言的实现导则。
IEC61131-3PLC编程语言国际标准是将现代软件概念和现代软件工程的机制与传统的PLC编程语言成功的结合,使它在产业控制领域的影响远远超出PLC的界限,已成为DCS、PC控制、运动控制以及SCADA的编程系统事实上的标准。IEC61131-3规定了二大类编程语言:文本化编程语言和图形化编程语言。前者包括指令语句表语言(IL)和结构化文本化语言(ST),后者包括梯形图语言(LD)和功能块图语言(FBD)。而顺序功能图(SFC)可以在梯形图语言中使用,也可以在指令语句表语言中使用。
IEC61131-3答应在同一个PLC中使用多种编程语言,也答应程序开发职员对一个特定的任务选择最合适的编程语言,还答应在同一个控制程序中其不同的软件模块用不同的编程语言编制,这一规定既解决了PLC发展历史形成编程语言多样化的现状,又为PLC的软件技术进一步发展提供了足够的空间。
欧美PLC厂商的PLC大都支持IEC61131-3标准,特别是西门子公司的PLC。我国在1995年就采用IEC61131-3作为PLC的国家标准。日本固然产业发达,技术还是相对封闭,但IEC61131-3标准成为PLC的公认世界主流标准后,日本的PLC生产商开始在新一代PLC软件平台中广泛采用。三菱电机的PLC编程软件包GXVer.8开发系统就支持梯形图语言(LD)、指令语句表语言(IL)、顺序功能图编程语言(SFC)、结构化文本语言(ST)。三菱电机的PX开发系统支持功能块图FBD,供PLC用于过程控制。欧姆龙公司的编程软件包GX除了支持LD、IL外,近期即将推出支持功能块FBD和结构化文本语言ST的编程软件包。富士电机的及横河电机的PLC编程软件包也都支持IEC61131-3。
