在应用PLC系统设计时,应遵循以下的基本原则,才能保证系统工作的稳定。
(1)***大限度地满足被控对象的控制要求;
(2)系统结构力求简单;
(3)系统工作要稳定、可靠;
(4)控制系统能方便的进行功能扩展、升级;
(5)人机界面友好。
本系统中,为了实现能源的充分利用和生产的需要,需要对电机进行转速调节,考虑到电机的启动、运行、调速和制动的特性,采用ABB公司的ABBACS800变频器,系统中由S7-200系列PLC完成数据的采集和对变频器、电机等设备的控制任务。基于S7-200PLC的编程软件,采用模块化的程序设计方法,大量采用代码重用,减少软件的开发和维护。系统利用对PLC软件的设计,实现变频器的参数设置、故障诊断和电机的启动和停止。
