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
Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
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
