S800 and S900 are distributed i/0 for process
control stations. They communicate with their controllers through Prof ibusdp Fieldbus
Communication, which can be installed in the controland 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 platform.

data gateway GS of the Industrial” system use this platform to ensure the system’s
Versatility, openness and ease of use, and bring great convenience to future technical
upgrades and maintenance.
System engineering is very convenient. The configuration
language is based on the IE061131 3 industry standard, providing function block diagram
(FBD), ladder diagram
(LD), instruction list (IL), sequential function chart (SFC),
structured text (ST) and other graphical configuration methods. The system contains
