T8123 Processor Interface Adaptor
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 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 and real-time process data are stored in RAM, and ram is installed on the Ethernet network card or battery card
The backup battery can maintain the configuration content and data in case of power failure.

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
