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。
2.程序模拟调试
程序模拟调试的基本思想是,以方便的形式模拟产生现场实际状态,为程序的运行创造必要的环境条件。根据产生现场信号的方式不同,模拟调试有硬件模拟法和软件模拟法两种形式。
1)硬件模拟法是使用一些硬件设备(如用另一台PLC或一些输入器件等)模拟产生现场的信号,并将这些信号以硬接线的方式连到PLC系统的输入端,其时效性较强。
