system design purpose: the most economical engineering investment and the most powerful
control function.
Industria1 “five features of DCS system:
1、 The comprehensive control
system integrates DCS & PLC & field bus;
2、 RISC superscalar high-speed CPU with super
performance;
3. High reliability, strict industrial application practice, and
application performance of more than 1000 sets in China;
4、 Good openness, flexibility
and expansibility;
5、 Easy engineering, friendly interface and simple maintenance;
2.
Industria1 “system communication
Industrial ial “the system uses the international
standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and
other countries
International standard fieldbus, PROFIBUS is the most widely used open
fieldbus international standard in the world, which is divided into FMS, DP and pa
Level
III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed
i/0 stations, field bus instruments and other intelligent devices.
The communication
among process station, operator station and engineer station is realized through the
system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45
twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and
network topology can be selected for the system bus
Due to the adoption of tcp/ip
protocol, the system can also realize ultra long distance communication with the help
of public telephone network (dial-up mode) or satellite.
PLC and other subsystems
communicate with industrial “system through Modbus protocol interface. The system also
supports iec870-5 over control coordination

The flash EPROM inside PS
provides more than 220 function modules (control algorithm subroutines), in addition to
