1746-OW16
据统计,2011年中国的小型PLC市场销售额约为27.3亿。目前小型PLC的技术源流主要分为日系和欧系,前者以三菱和欧姆龙为代表,后者则以西门子为首在我国的PLC行业,一些力量也已经在酝酿之中,大约有10-15家本地公司已经推出了小PLC产品。
工业发展在我国经济组成元素中相当于心脏对于人体的重要性,在工业产业中,机械是命脉,而机械的命脉又是什么呢?那就是小型PLC,在机械的使用中占有80%的使用率。PLC—可编程控制器,是在工业中应用最为广发的控制器。据统计,2011年中国的小型PLC市场销售额约为27.3亿(去税)。
目前小型PLC的技术源流主要分为日系和欧系,前者以三菱和欧姆龙为代表,后者则以西门子为首。而日系小型PLC进入中国的时间比较早,伴随我国轻工业的发展,以日系设计为主的原型机械不断引进,三菱、欧姆龙的产品也不断源源不断从香港进口而来。在之后的发展进程中,自动化巨头西门子在中国市场开始它的“侵略”,其代表性的小型PLC产品,S7-200逐渐现露头角,获得了很多大型OEM的青睐。到今天为止,从金额上看,西门子在小型PLC市场占据第一位,份额略超过30%。三菱仅随其后,约为四分之一。欧姆龙在11%强,台达则略过8%。
