(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…
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…
contains about 220 functions Algorithm library for energy blocks and a basic library with more than 200 graphic symbols and an extended library with a large number of 3D symbols. The system uses the same set of configuration tool software to complete the configuration and debugging of process level, operation level and even fieldbus instruments,…
communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard), Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application. The popular PC and MS_ Windows 2000 have been widely used in…
to connect the serial protocol equipment. The maximum transmission rate is 38.4kbd and can be configured. Its Standards Association Modbus Different physical interfaces can be selected for different connection schemes, RS422, RS485, RS232. All interfaces are electrical isolation Away. And the redundant operation is realized by two redundant field controllers. Fi8i0f card is a triple…
(through AUI interface) Ei803f provides 10Base-T twisted pair communication interface 32-bit data bus, 100 mb/s DMA (direct memory access) mode main memory ram, corresponding CPU operating load <4% Optional ram backup battery Fieldbus interface replacement card fi830f/fi820f/fi810f Fieldbus interface cards are divided into several types according to different protocol standards. Each interface card provides –…
battery card The backup battery can maintain the configuration content and data in case of power failure. Basic unit pmbo2f characteristics: mouth Installation slots of 4 fieldbus interface cards c Installation slot of 2 Ethernet network cards Support redundant operation of Fieldbus interface card Support hot plug of Fieldbus interface card Technical indicators of basic…
and a CPU motherboard. It periodically scans the data from the 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…
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…
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…
