①高可靠性
因DCS系统基于多台计算机控制,且系统架构采用了硬件冗余,网络容错设计,即使某个硬件出现故障,系统也能在ms级恢复,不会影响系统的正常运行。
②开放性
因DCS系统采用开放式,标准化,模块化,网络化设计,当需要增加或者改变一些功能时,可以通过增改硬件配置的方式实现要求。
③灵活性
当控制要求变更时,可以通过编程软件实现各种逻辑控制,复杂的算法,图形化显示等功能要求。
④控制功能强大
DCS系统的控制算法丰富,具有多种PID控制功能,如串级控制,前馈控制等,支持高级语言,可以编写更为复杂的算法。
在一组冗余设备中,一个链接设备充当主设备,并主动执行所有通信功能,包括H1链路上的链路主动调度器(LAS)功能。在冗余集中,主机和配置工具必须对主设备进行寻址。第二个链接设备名为Secondary device,用作备份设备。
它自动接收与主设备相同的配置,但在H1链路上使用不同的节点地址,在HSE上使用不同IP地址。如果主设备发生故障,辅助设备可以接管主设备的功能。在这种情况下,链接设备被简化为不能够容忍任何进一步故障的非冗余系统。

① High reliability
Because the DCS system is controlled based on multiple computers, and the system architecture adopts hardware redundancy and network fault-tolerant design, even if a hardware fails, the system can be recovered at the ms level without affecting the normal operation of the system.
② Openness
Because the DCS system adopts an open, standardized, modular, and networked design, when it is necessary to increase or change some functions, the requirements can be achieved by modifying the hardware configuration.
③ Flexibility
When the control requirements change, you can realize a variety of logic control, complex algorithms, graphical display and other functional requirements through programming software.
④ Powerful control function
DCS system control algorithm is rich, with a variety of PID control functions, such as cascade control, feed forward control, support high-level language, can write more complex algorithms.
In a set of redundant devices, one linked device acts as the master device and actively performs all communication functions, including the link active scheduler (LAS) function on the H1 link. In a redundant set, hosts and configuration tools must address the primary device. The second linked device is called Secondary device and is used as a backup device.
It automatically receives the same configuration as the main device, but uses a different node address on the H1 link and a different IP address on the HSE. If the primary device fails, the secondary device can take over the functions of the primary device. In this case, the linked device is reduced to a non-redundant system that cannot tolerate any further failure.
