因此相当多的企业会希望能通过提升自动化的程度来减少人工、能耗降低排污。这对于自动行业而言是一次千载难逢的好机会，低成本低性能低品质的三低现状可能在未来的几年内得到根本的改善。所有的部分都将需要自动化厂商的跟进，相应的相当多的更加的行业解决商和与行业相结合的产品会大放光彩。
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。
三、自主研发
自主研发分两类，一类是土八路，按自已的理解根据一个数学模型进行PLC的开发，然后在实际应用中不断的完善和修改，这类厂商大多在一到两年后就会碰到是否要推翻现有体系结构重新开发的问题，产品的局限性也比较大。
另一类是维新派，主张洋为中用，通过消化和吸收国外的技术再自行开发，这类开发一般成功的机会的比较大，起码能成为产品，但这类厂商都会因为对引进部分的吸收周期而使自已的设计受到限制，需要经过两轮研发后才能真正的理解和破茧而出。基本上我个人属于这一类，因此也比较看好这一类厂家的成长，因为可以看通整个PLC产品发展的历史和规律。
