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，比如西门子和ABB的Profibus、ABB的CAN bus、施耐德的Modbus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。现场IO模块，特别是模拟量的采样数据（机器代码，213/扫描周期）十分庞大，同时现场干扰因素较多，因此应该采用数据吞吐量大、抗干扰能力强的网络标准。基于RS485串口异步通讯方式的总线结构，符合现场通讯的要求。
IO的采样数据经CPU转换后变为整形数据或实形数据，在操作级网络（第二层网络）上传输。因此操作级网络可以采用数据吞吐量适中、传输速度快、连接方便的网络标准，同时因操作级网络一般布置在控制室内，对抗干扰的要求相对较低。因此采用标准以太网是最佳选择。TCP/IP协议是一种标准以太网协议，一般我们采用100Mbit/s的通讯速度。
PLC系统的工作任务相对简单，因此需要传输的数据量一般不会太大，所以常见的PLC系统为一层网络结构。过程级网络和操作级网络要么合并在一起，要不过程级网络简化成模件之间的内部连接。PLC不会或很少使用以太网。
