“field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different), Each card is connected to a fieldbus to collect process data and…
PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices. The communication among process station, operator station and engineer…
level, operation level and even fieldbus instruments, and uses the same A global database. The system scale has strong scalability. The single system supports 1 to 100 control stations and 100 operation stations at most. Each control The station can support thousands of i/0 points at most, and the scale of the whole system can…
