DCS过程控制系统已经介绍过，可把系统分成四个级，分别是现场级、控制级、监控级和管理级。联络控制级与监控级的那个过程控制网络在实际工作中非常重要，因为这个网络直接决定了我们的操作人员能否及时准确的发现现场设备的各种数据是否正常、是否有报警出现，同时我们的各种指令是否能时间发送到现场设备上去。所以各个DCS大咖们都在这个网络上用尽了心思。

简单给大家梳理一下：从DCS系统产生至今，随着科学技术的发展这个过程控制网络也历经几代。

解决一个生产装置的几个控制站和一个或几个操作站直接的数据联络的应该算代，当时的速度很慢，慢到以波特率计算（比如90年代我使用的DCS是9600bps）,操作工获取现场数据非常滞后；

DCS process control system has been introduced, the system can be divided into four levels, respectively, field level, control level, monitoring level and management level. The process control network of the contact control level and monitoring level is very important in actual work, because this network directly determines whether our operators can timely and accurately discover whether the various data of the field equipment is normal, whether there is an alarm, and whether our various instructions can be sent to the field equipment. So the DCS big guys are in this network to exhaust the mind.

Simply give you a review: from the DCS system so far, with the development of science and technology, this process control network has also gone through several generations.

To solve the problem of direct data contact between several control stations and one or several operating stations of a production unit, the speed was very slow, slow to baud rate calculation (for example, the DCS I used in the 1990s was 9600bps), and the operator obtained field data was very lagging;
