more than 1000 sets of application performance in China;
4. It has good openness,
flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and
the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses
international standard industrial bus. Field controller supports Profibus, FF, ModBus,
Can, etc.
International standard fieldbus, Profibus is the most widely used open
fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP
communication rate can be as high as 12Mb. Profibus is used to connect intelligent
devices such as distributed I/0 stations and field bus instruments.
Communication
between the process station, operator station and engineering station takes place via
the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45
twisted pair, thin, thick or fiber optic cables and mixed media) and network topology
can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol,
the system can also use the public telephone network (dial-up mode) or satellite to
achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the
Industrial” system through the ModBus protocol interface. The system also supports
IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more
than 220 functional modules (control algorithm subroutines), in addition to the basic
ones specified in the IEC 61131 3 standard
In addition to this content, many powerful
and rigorously tested function blocks from actual engineering applications have been
expanded. any complex control
The scheme can be realized by the combination of these
function blocks.
The function blocks provided by the system mainly include the following
categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence
control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface

4.2 Field Controller PS
Industrial” field
controller PS is a special process control station, which is embedded with field bus
communication interface for users to use
Fieldbus technology offers very flexible
options. Each PS allows to insert 4 fieldbus interface cards (the card type can be
different),
Each card is connected to 1 field bus to collect process data and diagnostic
information from the bus, the interface card is easy to replace and plug and play
(Plug
& Play), and can be plugged and unplugged.
The field controller PS has the following
characteristics:
o
Flexible: supports all international standard open fieldbuses and can
be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple
engineering: configuration, commissioning and diagnostics using only the same tool CBF
