2、MADE IN CHINA的PLC何去何从

PLC技术真正在中国开始大力发展应是这几年的事情，采用软PLC编译或者解释方式实现的各种PLC厂商以一个月一家的速度在中国的各个地方冒出来。

二、引进

引进是早一批PLC厂商都采取过的方式，通过引进可以很快的了解很多技术的内核，目前比较常用的是硬件自行设计，软件引进，特别是编程软件，目前ISAGRF、KW、INFORTEM、3S等都在国内有常设或代理商，他们大多是欧洲的公司，也是IEC61131现实的支持者和获利者。但IEC61131-3中存在的问题也是限制了使用这些软件的厂商快速发展的一个瓶颈。这个问题以后有时间再慢慢解说了。

基本上引进的都没有达到大家当初所预期的效果。
