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
Discussion.
The flash EPROM inside PS
provides more than 220 function modules (control algorithm subroutines), in addition to
the base specified in IEC 61131 3 standard
In addition to this content, many powerful
and strictly tested function blocks from practical engineering applications are also
expanded. Any complex control
All schemes can be realized by the combination of these
function blocks.
The function blocks provided by the system mainly fall into the
following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop
adjustment
Logical sequence control
c
Logical operation
Monitoring function
