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) .

as well as high-speed logic and sequence control equivalent to high-grade PLC indicators
Braking performance. The system can connect not only conventional i/0, but also PROFIBUS, FF, can, MODBUS and other field bus devices. System tool
It has high flexibility and excellent scalability, whether it is the control of small-scale production devices or the large-scale integrated control of the whole plant, even
The industrial “system can cope with the field equipment maintenance management and cross plant production management control applications
As an important member of industrial “family, AC800F system fully embodies industrial” initiated and led by ABB in technology

Information technology) a new trend.
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
Line. The field controller supports various field buses such as PROFIBUS, which is the most widely used open field bus in the world
Line international standard, divided into FMS, DP and PA, DP communication rate can be as high as 12MB. Can (din/is011898 standard) bus
The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform

It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.
System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
