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…
global database. The system scale has strong scalability. The single system supports 1 to 100 control stations and 100 operation stations at most. Each control The station can support thousands of i/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is all metal…
communication with intelligent field instruments is through IART protocol or fieldbus (31.25kb profibuspa and FF Bus). 版权归千图网所有，盗图必究 The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard), The user can select the communication transmission medium (ordinary cable or optical fiber) and…
various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control Control, sequence control and batch intermittent control functions. 版权归千图网所有，盗图必究 The internal communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general Line. The field controller…

configuration and PS The user program is downloaded to the PS CPU through diginets and the first network card. After the field bus interface card is newly installed or replaced, the required group The status information will be automatically reloaded. The configuration results and real-time process data are stored in RAM, and ram is installed…
corresponding fieldbus actuator. Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master and slave PS. Two on each PS Ethernet network card, the second network card is used to connect the system network diginets), and the second network cards can be interconnected with each other to form a special Redundant communication…
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…
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…
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…
