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 configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols.
The system uses the same set of
