DCS的配置能够实现机组停止时，另一台机组的运行人员能对公用系统进行监控，并且要求采用可靠的措施，确保其控制命令的性，即在同一时间只允许一套DCS系统对公用设备起控制作用。不能因为公用系统的存在，而使2台机组的DCS耦合在一起。

在工程实际应用过程中，依照DCS的特点采用了2种典型的方法来实现对公用系统的控制。DCS是HITACHIHIACS7000系统，在DCS的配置中，我们在机组中配置相同的硬件和软件，通过切换开关来实现操作权的转换。

中继器或集线器（hub）也是物理层的设备，它与传输的信息帧的具体内容无关。帧是发送到介质上的一组数字脉冲。用以传输信息。帧的大小为64-1518字节。帧包括预同步信号，消息头、数据信息和帧校验序列。

DCS can be configured so that when the unit stops, the operator of another unit can monitor the common system, and requires reliable measures to ensure the nature of its control commands, that is, only one DCS system is allowed to control the common equipment at a time. The DCS of two units cannot be coupled together because of the existence of a common system.

According to the characteristics of DCS, two typical methods are used to control the common system in practical engineering application. DCS is a HITACHIHIACS7000 system, in the configuration of DCS, we configure the same hardware and software in the unit, through the switch to achieve the conversion of operation rights.

A repeater or hub is also a physical layer device that is independent of the specific content of the transmitted information frame. A frame is a set of digital pulses sent to a medium. Used to transmit information. The frame size ranges from 64 to 1518 bytes. The frame includes pre-synchronization signal, message header, data information and frame check sequence.
