1.特点顺序控制系统是指按照预定的受控执行机构动作顺序及相应的转步条件,一步一步进行的自动控制系统。其受控设备通常是动作顺序不变或相对固定的生产机械。这种控制系统的转步主令信号大多数是行程开关(包括有触点或无触点行程开关、光电开关、干簧管开关、霍尔元件开关等位置检测开关),有时也采用压力继电器、时间继电器之类的信号转换元件作为某些步的转步主令信号。
为了使顺序控制系统工作可靠,通常采用步进式顺序控制电路结构。所谓步进式顺序控制,是指控制系统的任一程序步(以下简称步)的得电必须以前一步的得电并且本步的转步主令信号已发出为条件。对生产机械而言,受控设备任一步的机械动作是否执行,取决于控制系统前一步是否已有输出信号及其受控机械动作是否已完成。若前一步的动作未完成,则后一步的动作无法执行。这种控制系统的互锁严密,即便转步主令信号元件失灵或出现误操作,亦不会导致动作顺序错乱。
