传统DCS即将退出市场，新型系统可以是集成的，也可以由DCS厂家作为系统供应的。对于集成系统可以是操作站采用通用的，控制器有许多接口，与PLC，Web连用。用户可以通过工程公司集成，应按照项目的规模大小和预算资金来选择使用。由于有通用的监控软件，符合IEC61131-3标准的编程软件、可以选用嵌入式系统或软DCS系统，集成的控制系统有可能达到最高的性价比。

系统规模主要由系统的输入输出点数确定。其中包括连锁、特殊控制要求所需的输入输出点数。选择DCS的型号要看资金确定和维护的工作量，有的DCS除操作站需要维护以外，控制部分基本不需维护。

在选型时，要考虑是否需要冗余。新型DCS的通讯网络是冗余的，结点之间距离和DCS网络总长度以及各结点地理配置有关。通用以太网，网卡等价格很低，而专用网络接口很贵。经济性涉及很多因素，最好联系国内类似单位，进行技术培训，或请教有经验的专家解决有关困难。

The traditional DCS is about to exit the market, and the new system can be integrated or supplied by the DCS manufacturer as a system. For the integrated system can be the operation station to adopt universal, the controller has many interfaces, with PLC, Web. Users can integrate through engineering companies, and should choose to use according to the size of the project and budget funds. Due to the universal monitoring software, IEC61131-3 standard programming software, can choose embedded systems or soft DCS system, integrated control system is possible to achieve the highest cost performance.

The system size is mainly determined by the number of input and output points of the system. This includes the number of input and output points required for interlocking and special control requirements. The choice of DCS model depends on the funds to determine and maintenance of the workload, some DCS in addition to the operation station needs to be maintained, the control part of the basic no maintenance.

When selecting, consider whether redundancy is required. The communication network of new DCS is redundant, and the distance between nodes is related to the total length of DCS network and the geographical configuration of nodes. General Ethernet, network cards, etc. are very cheap, and private network interfaces are very expensive. Economy involves many factors, it is best to contact similar domestic units, technical training, or consult experienced experts to solve the relevant difficulties.
