在数控机床出现以前，顺序控制技术在工业生产中已经得到广泛应用。许多机械设备的工作过程都需要遵循一定的步骤或顺序。顺序控制即是以机械设备的运行状态和时间为依据，使其按预先规定好的动作次序顺序地进行工作的一种控制方式。
数控机床所用的顺序控制装置（或系统）主要有两种，一种是传统的“继电器逻辑电路”，简称RLC（Relay Logic Circuit）。另一种是“可编程序控制器”，即PLC。
RLC是将继电器、接触器、按钮、开关等机电式控制器件用导线连接而成的以实现规定的顺序控制功能的电路。在实际应用中，RLC存在一些难以克服的缺点。如：只能解决开关量的简单逻辑运算，以及定时、计数等有限几种功能控制，难以实现复杂的逻辑运算、算术运算、数据处理，以及数控机床所需要的许多特殊控制功能，修改控制逻辑需要增减控制元器件和重新布线，安装和调整周期长，工作量大；继电器、接触器等器件体积较大，每个器件工作触点有限。当机床受控对象较多，或控制动作顺序较复杂时，需要采用大量的器件，因而整个RLC体积庞大，功耗高，可靠性差等。由于RLC存在上述缺点，因此只能用于一般的工业设备和数控车床、数控钻床、数控镗床等控制逻辑较为简单的数控机床。
