进入90年代以后,由于计算机网络技术的迅猛发展,使得DCS系统得到进一步发展,提高了系统的可靠性和可维护性,在今天的工业控制领域DCS仍然占据着主导地位,但是DCS不具备开放性,布线复杂,费用较高,不同厂家产品的集成存在很大困难。
从八十年代后期开始,由于大规模集成电路的发展,许多传感器、执行机构、驱动装置等现场设备智能化,人们便开始寻求用一根通信电缆将具有统一的通信协议通信接口的现场设备连接起来,在设备层传递的不再是I/O(4~20mA/24VDC)信号,而是数字信号,这就是现场总线。由于它解决了网络控制系统的自身可靠性和开放性问题,现场总线技术逐渐成为了计算机控制系统的发展趋势。从那时起,一些发达的工业国家和跨国工业公司都纷纷推出自己的现场总线标准和相关产品,形成了群雄逐鹿之势。
