程消息类型指定不同的优先级(从0~5),系统故障另分成三个优先级(SI ~S3).不同优先级的消息
以不同的颜色显示并可选择不同的确认方法。此外还显示过程点的名称和故障状态。所有消息均可

消息行
二,
各种显示画面的项部区均为消息行,用以对来自整个重重雪
过程的各种不同消息类型进行更高-级的显示。消息行显
示最末或最先的5个消息,以及消总确认和操作员提示调
出按钮。消息行还有消息容量溢出指示区和未确认消息个
数显区.

故障过程点的面板窗口可从消息行直接调出以便快速操作。

最末产生的消息在消息- -览表的首行或尾行。消息的时间排序方式(升序或降序)可以在线更改。同消

为观察更加清晰,操作员可把某个优先级或装置区域的消息暂时从屏幕上取消而不显示。消息-
览表的容量大小由组态决定,如果当前的消息数目超过所组态的容量规模,则先进入的消息被删除,
以让出空间给当前消息进入。
操作员提示览表
对于每个过程报警消息和开关动作消息均可组态相应的操作员提示。该提示可以通知操作员消息
出现的原因及为消除故障应采取的相应措施等内容。如果需要该提示还可为操作员提供更多的帮助。
操作员提示一览表显示列出了所组态的全部提示。同时可发出提示声音(如人声) .
记录
记录用于记录来自过程的事件.状态和顺序。记录文件可存贮在硬盘上,可在监视器上显示、通

另外记录文件可自动通过FTP协议发送到以太网上的任何节

这些数据或转换成ASCII码文件。
Industrial”系统有以下记录类型:
信号顺序记录(SOE)
信号顺序记录用于记录各种事件,如过程和系统报警、开关动作消息、操作员干预和提示。组态

生产报表记录
生产报表记录是指在–定的时间间隔内或在某种情况下,记录下过程变量的当前值或状态。该记

事故迫忆记录
事故追忆记录用于检查分析事故的详细过渡过程(脉络波形)。为实现这–目的,系统以极高的时

The system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized
Can (operate and display, print, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems
Yes. The process control level realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general
