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…
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…
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…

Time required to process 1000 IL (instructions): < 1.0 ms (processing binary and 16 bit arithmetic instructions) <2ms (processing fixed-point arithmetic instructions) < 1.5ms (processing 32-bit floating-point arithmetic instructions) Bthernet…
PS basic unit provides the interface between PS and diginets. ES. Hardware 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…
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 Ethernet network card, the second…
