Profibus-DP被设计用来在中心控制器模块(比如PLC或PC)之间迅速地传送过程数据，并在现场级别中分散现场模块（此如I/O模块、驱动和真空管）。通信主要以循环方式进行。对于智能现场模块，在循环地传送数据过程中的参数分配、诊断及告警处理还需要非循环的通信功能。
利用Profibus-DP可实现单一主设备系统和多个主设备系统。多个主设备系统由功能独立的子系统构成，每个子系统包括一个主设备和一部分从设备，所有这些集成在一个完整的系统中。
(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 subroutin
es), 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
1EC870-5 protocol communication interface (Telecontrol)
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 (Control Build F) software
mouth
Access to all information from the field including equipment management information
Global database of fieldbus devices, control levels and HMI (Human Machine Interface) usage systems
Module identification with production
