从时间调度上来说：PLC的程序一般不能按事先设定的循环周期运行。PLC程序是从头到尾执行一次后又从头开始执行。（现在一些新型PLC有所改进，不过对任务周期的数量还是有限制）而DCS可以设定任务周期。比如，快速任务等。同样是传感器的采样，压力传感器的变化时间很短，我们可以用200ms的任务周期采样，而温度传感器的滞后时间很大，我们可以用2s的任务周期采样。这样，DCS可以合理的调度控制器的资源。从网络结构发面来说：一般来讲，DCS惯常使用两层网络结构，一层为过程级网络，大部分DCS使用自己的总线协议，比如横河的Modbus、西门子和ABB的Profibus、ABB的CANbus等，这些协议均建立在标准串口传输协议RS232或RS485协议的基础上。
