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…
