(3)采用继电器输出时,所承受的电感性负载的大小,会影响到继电器的使用寿命,因此,使用电感性负载时选择继电器工作寿命要长。
在控制系统逻辑关系较复杂(需要大量中间继电器、时间继电器、计数器等)、工艺流程和产品改型较频繁、需要进行数据处理和信息管理(有数据运算、模拟量的控制、pid调节等)、系统要求有较高的可靠性和稳定性、准备实现工厂自动化联网等情况下,使用plc控制是很必要的

生产plc产品的各厂家都在大力度地开发自己的新产品,以求占据市场的更大份额。因此产品向多样化方向发展,出现了欧、美、日多种流派。与此同时,为了推动技术标准化的进程。一些国际性组织,如国际电工委员会(iec)不断为plc的发展制定一些新的标准,如对各种类型的产品作一定的归纳或定义,或对plc未来的发展制定一种方向或框架。
plc的性能倚赖于专用的硬件,plc的应用程序是依靠专用的硬件芯片来实现的,对于plc的功能的改进,如增加运动控制、过程控制或通讯功能,都需要使用不同的硬件。即使对于同一plc厂家,这种专用的硬件很难移植到不同性能的plc中。而且传统的plc厂家的硬件结构体系都是专有的设计,甚至于处理器芯片都是专用的,这样就导致了随着plc功能需求的不断提高,plc的硬件体系变得越来越复杂。
