Fieldbus interface replacement card fi830f/fi820f/fi810f
Fieldbus interface cards are divided into several types according to different protocol standards. Each interface card provides – a fieldbus interface (PROFIBUS,
Can, FF, MODBUS, etc.). The configuration and parameter settings of the interface card itself and the field instrument (or remote i1/0) on the connected fieldbus are still
It is designed by the industrial “unified tool control bui lder without additional software. The interface card can be configured redundantly (separated between each other
Redundant basic unit pm802f) and can be plugged in and out and replaced online.
Fi830f: PROFIBUS DP interface card, as the master station, can connect 126 PROFIBUS DP slave stations, and the communication rate can reach 12mbd
One PS can plug in 4 fieldbus interfaces, connect 496 fieldbus devices, and one city (subsystem) of industrial “system can
Connect 4960 fieldbus devices (10000 i/0).
Fi820f: two serial interfaces are provided 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 can bus protocol interface card (rate 1mbd) used to connect industrial ial “conventional process control station
The i/0 protection unit of the PS is used to receive process signals from the rack mounted i/0 modules supported by the PS. Each field controller PS can only be configured
-Block fi810f card. — The two fi810f interface cards on the redundant PS. can be switched redundantly.
S800 and S900 are distributed i/0 for process control stations. They communicate with their controllers through Prof ibusdp Fieldbus
Communication, which can be installed in the controland PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system 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 various fields all over the world, becoming the de facto standard computer platform.
