有些人,似荷,只能远观;有些人,如茶,可以咀嚼;有些人,像风,不必在意;有些人,是树,值得依靠。我们要不拘一格,任何人都不是你的复制与想像,不必用自己的需求,要他人是什么或不是什么,做什么或不做什么。每人都有喜欢的生活,没人是你的全集。时光,浓淡相宜;人心,远近相安
1981-至今,iec正式发表了plc的标准,各厂家的plc都向规范化发展。梯形图、语句表、sfc语言已经成熟,同时还有和编程语言的接口,其存储能力、运算速度、对模拟量的处理功能已经大大加强,现在的大中型plc已经具有以前dcs所“特有”的经典pid算法、斜坡函数、自适应算法、模糊控制等算法。
plc特点和功能
plc的主要特点。plc的特点是:工作可靠、运行速度快、积木式结构、组合灵活、良好的兼容性、程序编制及生成简单、丰富、网络功能强。
plc的主要功能。plc系统能很好的完成工业实时顺序控制、条件控制、记数控制、步进控制等功能;能够完成模/数(a/d)、数/模(d/a)转换、数据处理、通讯联网、实时监控等功能。
