四、显示功能的发展系统的过程连接口箱与遍布工厂的过程传感器和终控元件相连。并对进出的讯号进行调节、检查和控制。由数据公路携带的信息经通道传递到局部控制网络,接口和通道将数据进行转换以便与其它的源数据相一致。为了实现对数据的集中监视和操作,TDC2000配备了操作站(B)和管理站(S)i TDC3000配备了增强型操作站(EOS)和万能操作站(us)。它们都是以微处理机为基础、与数字通讯及CRT 显示技术相结合的人机接口。过程或工厂的控制取决于过程参数的即时识别。采用一种按“例外情况进行操作”的监视技术可方便地解决这一任务。这种监视方法突出显示那些偏离了正常操作的控制回路或过程装置。TDC 系列采用棒图偏差表示法有助于监视多个回路,以PV 数值精确表示其
Fourth, the development of the display function The process of connecting the system to the mouth of the box and the factory process sensors and control components connected. And on the incoming signal to adjust, check and control. Information carried by the data highway is routed to the local control network, which interfaces and channels translate the data for consistency with other source data. The TDC2000 is equipped with Operator Station (B) and Management Station (S) for centralized monitoring and operation of the data. The TDC3000 is equipped with an Enhanced Operator Station (EOS) and a universal operator station (us). They are based on a microprocessor, and digital communications and CRT display technology combined with human-machine interface. Process or plant control depends on the instantaneous identification of the process parameters. This task can easily be solved by using a monitoring technique that operates “on an exceptional basis.” This monitoring method highlights those control loops or process devices that deviate from normal operation. The TDC Series uses bar graph deviation notation to help monitor multiple circuits, accurately characterizing PV values
