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 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 link (diginetr) to ensure information synchronization between master and slave PS. — However, the master PS fails, and the slave PS can quickly and undisturbed connect the replacement worker
Make. All inputs and outputs also support redundant operation.
The data communication between the field process controller PS. operating station 0s and the engineer station es is completed by the system network (diginets), which is inserted
The – Ethernet network card on the PS basic unit provides the interface between PS and diginets. ES. Hardware configuration
