程序设计
1.程序设计
根据系统的控制要求,采用合适的设计方法来设计PLC程序。程序要以满足系统控制要求为主线,逐一编写实现各控制功能或各子任务的程序,逐步完善系统的功能。除此之外,程序通常还应包括以下内容:
1)初始化程序。在PLC上电后,一般都要做一些初始化的操作,为启动作必要的准备,避免系统发生误动作。初始化程序的主要内容有:对某些数据区、计数器等进行清零,对某些数据区所需数据进行恢复,对某些继电器进行置位或复位,对某些初始状态进行显示等等。
2)检测、故障诊断和显示等程序。这些程序相对独立,一般在程序设计基本完成时再添加。
3)保护和连锁程序。保护和连锁是程序中不可缺少的部分,必须认真加以考虑。它可以避免由于非法操作而引起的控制逻辑混乱。
