DCS系统的关键是通信。也可以说数据公路是分散控制系统DCS的脊柱。由于它的任务是为系统所有部件之间提供通信网络，因此，数据公路自身的设计就决定了总体的灵活性和安全性。数据公路的媒体可以是：一对绞线、同轴电缆或光纤电缆。
通过数据公路的设计参数，本上可以了解一个特定DCS系统的相对优点与弱点。
（1）系统能处理多少I/O信息。
（2）系统能处理多少与控制有关的控制回路的信息。
（3）能适应多少用户和装置（CRT、控制站等）。
（4）传输数据的完整性是怎样彻底检查的。
（5）数据公路的Z大允许长度。
（6）数据公路能支持多少支路。
（7）数据公路是否能支持由其它制造厂生产的硬件（可编程序控制器、计算机、数据记录装置等）。为保证通信的完整，大部分DCS厂家都能提供冗余数据公路。
为了保证系统的安全性，使用了复杂的通信规约和检错技术。所谓通信规约就是一组规则，用以保证所传输的数据被接收，并且被理解得和发送的数据一样。
目前在DCS系统中一般使用两类通信手段，即同步的和异步的，同步通信依靠一个时钟信号来调节数据的传输和接收，异步网络采用没有时钟的报告系统。
