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

The scheme can be realized by the combination of these function blocks.
The

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

Access to all information from the field including
equipment management information
