plc的发展趋势 

      有极快的逻辑运算和极强的逻辑控制、顺序控制能力，在离散控制中有无与伦比的可靠性，方便简单易学的编程方法，使其在以离散为主的工业自动化领域中有无可争议的领导地位。

全球工业计算机控制领域，围绕开放与再开放过程控制系统、开放式过程控制软件、开放性数据通信协议，已经发生巨大变革，几乎到处都有plc，但这种趋势也许不会继续发展下去。随着软plc(softplc)控制组态软件技术的诞生与进一步完善和发展，安装有softplc组态软件和基于工业pc控制系统的市场份额正在逐步得到增长，这些事实使传统plc供应商在思想上已经发生了戏剧性的变化，他们必须面对现实，在传统plc的技术发展与提高方面做出更加开放的高姿态。对于控制软件来讲，这是plc控制器的核心，plc供应商正在向工业用户提供开放式的编程组态工具软件，而且对于工业用户表现得非常积极。此外，开放式通信网络技术也得到了突破，其结果是将plc融入更加开放的工业控制行业。

（6）过程控制和管理功能。随着plc、dcs和ipc（工业现场控制用计算机）之间的竞争逐步加强，各plc厂家正在逐步将传统dcs所特有的过程控制功能逐步移植到plc中，使其在过程控制领域能够与dcs进行竞争，这方面plc已经取得了很大的成果。为了满足生产管理的需要,各plc厂家也在其软件开发上增加了管理软件，通过与其plc 的实时通讯采集现场数据 

并通过相应的软件完成生产管理所需要的管理功能。
