us, 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
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
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)troller PS has the following features:
o
Flexible: it supports all international standard open fieldbus and can be mixed
4 high-speed fieldbuses can be connected at the same time (max. 12 MBD)
Simple project: only use the same tool CBF (control build f) software for configuration, debugging and diagnosis
mouth
Access to all information from the site, including equipment management information
Global database of Fieldbus equipment, control level and HMI (human-machine interface)
Module identification with production operating parameters
c
Complete self diagnosis
Compact and rugged design
Front panel wiring
DIN rail (U-shaped) mounting well can be directly installed on the wall, which is simple and convenient
o
Allowable operating ambient temperature 60 C, automatic temperature monitoring
o
EMC (electromagnetic compatibility) conforms to en50082 standard

Certification: CE, Namur, CSA, csa-nrtl, FM class 1 div2, ghost, Lloyd
Installation area: Class 1 div 2
The PS supports the following types of fieldbus standards:
Profibus DP，up to 12 MBd
Modbus RTU，1200 to 38. 4KBd
Industrial” CAN I/0 Bus
o
Open CAN -Bus，up to 1 MBd
o
Foundation Fieldbus H1
up to 31. 25KBd
Foundation Fieldbus H2 (fast Ethernet)
HART
The system allows different types of field buses to be mixed and run simultaneously in the same field controller PS.
Industrial “field control explosion (AC800F) consists of the following components:The signals of the field bus sensors are processed according to the control application program configured by the user, and then the calculation results are passed
The fieldbus interface card returns the corresponding fieldbus actuator.
Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master and slave PS. Two on each PS

Various accessories
The main components of the field controller PS are described below.
Basic unit pm802f
The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different),
Each card is connected to a fieldbus 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 in and out with power.
