PLC在向微型化、网络化、PC化和开放性方向发展

全**PLC生产厂家约200家，生产300多种产品。国内PLC市场仍以国外产品为主，如Siemens、Modicon、A-B、OMRON、三菱、GE的产品。经过多年的发展，国内PLC生产厂家约有三十家，但都没有形成颇具规模的生产能力和名牌产品，可以说PLC在中国尚未形成制造产业化。在PLC应用方面，中国是很活跃的，应用的行业也很广。**估计，2000年PLC的国内市场销量为15~20万套（其中进口占90%左右），约25~35亿元人民币，年增长率约为12%。预计到2005年全国PLC需求量将达到25万套左右，约35~45亿元人民币。

PLC市场也反映了全**制造业的状况，2000后大幅度下滑。但是，按照Automation Research Corp的预测，尽管全球经济下滑，PLC市场将会复苏，估计全球PLC市场在2000年为76亿美元，到2005年底将回到76亿美元，并继续略微增长。

微型化、网络化、PC化和开放性是PLC未来发展的主要方向。在基于PLC自动化的早期，PLC体积大而且价格昂贵。但在**近几年，微型PLC（小于32 I/O）已经出现，价格只有几百欧元。随着软PLC（Soft PLC）控制组态软件的进一步完善和发展，安装有软PLC组态软件和PC-based控制的市场份额将逐步得到增长。

当前，过程控制领域**的发展趋势之一就是Ethernet技术的扩展，PLC也不例外。如今越来越多的PLC供应商开始提供Ethernet接口。可以相信，PLC将继续向开放式控制系统方向转移，尤其是基于工业PC的控制系统。
