  PLC(ProgrammableLogicController)产生于上世纪70年代初。最早的PLC是以替换继电器系统的角色出现，其主要实现的功能仅仅是逻辑简单的顺序控制功能。PLC一经出现，就以其高可靠性、小体积和直观的编程模式而显示出强大的生命力，成为自动控制领域的“明星”。     PC-based是一种基于PC技术的控制系统。最早的PC-based控制系统是以工控机为核心，通过扩展带PCI接口的专用板卡组成。PC-based借助于IT技术的发展，在运算、存储、组网和软件开放性方面具有优势。     PLC和PC-based两者在技术特点上存在明显区别。PLC具有体积小、功耗低、抗干扰能力强；具有很高的可靠性，其平均无故障率时间间隔（MTBF）可达50万、甚至100万个小时；具有简单直观的编程模式(如梯形图)；具有内部实时时钟。而PC-based具有大运算能力；具有开放标准的系统平台和PCI接口；精美且低成本的显示技术；丰富的组网能力。但系统的可靠性略差，如性能较好的IPC的平均无故障时间间隔约5万小时。此外，PC-based虽然具有很强的CPU，但其多任务操作系统是非实时的，所以程序的循环周期反而没有高性能的PLC快。 PLC更适合于设备控制，而PC-based更多地用于设备运行状态的监视。相对于PC-based而言，PLC具有配置灵活、体积小、适应恶劣环境、抗干扰性强、可靠性高等优点，但在软件功能及系统开放性等方面比PC-based稍差。当然，随着计算机技术和控制技术的不断发展，PLC和PC-based都在吸收对方的优点，以适应更多的应用现场。例如，PLC在包装设备中的应用远远多于PC-based在包装设备中的应用。     随着PC-BASED的工业计算机（简称工业PC，与普通的计算机相比，它具有防尘、防振、抗电磁、耐高低温等优点）的发展，以工业PC、I/O及监控装置、控制网络组成的PC-BASED的自动化系统逐渐成为工业自动化的另一种实现方式。PC-BASED自动化系统源于PC，可完全融入到网络时代的信息系统中，具有高性能、低价格、系统开放、丰富的人才和应用基础等优势。
