PLCOPEN将PLC定义为：具有编程能力的固态控制系统
PLC主要的功能就是通过编程后实现用户需要的各种类型的控制功能，前面已经说过在没有PLC之前，大家要通过很多专用电路或者继电器组来完成控制功能。现在PLC广泛的应用于几乎所有的行业中，我们身边的绝大多数产品都是由PLC控制的装备制造出来的。比方说塑料、包装、造纸、冶金、石化、电梯、木工、陶瓷等等。
因为控制的方式不同，以前大家分为过程控制和顺序控制或者离散控制两类，其中过程控制来源于早期的过程仪表控制，后逐步发展为DCS，而顺序控制来源于早期的继电器组，后发展出了PLC，但随着微电子、软件、硬件和通信技术的发展，目前很多DCS和PLC都采用同样的或者类似技术平台，双方之间区别越来越小，大多数新一代的控制系统都不再区分DCS或者PLC，不过新一代控制器是否叫PLC还是DCS或者FCS、PAC、NCS，这并没有得到广大厂商的认同。特别是网络和现场总线的发展，使DCS越来越没有单独存在的价值，很多的国际大公司都把新一代的控制系统合并了DCS、PLC、IPC、FCS功能。
为了简化各种概念，我们根据项目的大小、项目的重复度把PLC的应用分为工程和OEM两部分，其中工程主要指造纸、石化、冶金、水泥、大型港机等项目特征明显的自动化系统，而OEM主要指各种使用PLC的装备，如电梯、挤出机、包装机、回流焊、点胶机、特种车辆等，”这两大块构成了PLC的主要的市场。
