ABB GJR2363900R1000variety of international field bus standards. It has both the complex analog loop regulation capability of DCS
Power-friendly human-machine interface (HMI) and convenient engineering software, and at the same time have high-speed logic and sequence control equivalent to high-end PLC indicators.
control performance. The system can be connected to both conventional I/0 and various field bus devices such as Profibus, FF, CAN, and Modbus. system tool
It has a high degree of flexibility and excellent scalability, whether it is the control of small production units, or the control of ultra-large-scale whole plants – integrated control, even
The Industrial” system can handle the application of field equipment maintenance management and cross-plant production management control with ease.
An important member of the Industrial” family, the AC800F system fully embodies the Industrial” (Industrial Information) system pioneered and led by ABB in technology.
information technology) new trends.
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
function (operation and display, printing, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems.
can. The process control stage 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 controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world.
Line international standard, divided into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer
