Fieldbus process control communication system( LonWorks)
Abstract:Fieldbus is a correspondence to used for the process automation with make rock-bottom the spot in automation equipments or the spot gauges with each other network, is the spot correspondence network to gather with control system.Along with the continuously increasing of the fieldbus product price ratio, people are adopting fieldbus to proceed to supervise and control to the equipments more and more.This design passes to the LonWorks application, making us having an understanding for probably to fieldbus.
This design is to design a three layers mold piece, among them stand the server, engineer stands with the operator the conduct and actions first floor receive the ether net, total and linear design in the spot and linear correspondence in gross system design conduct and actions second floor, the spot gauge and equip for the third layer.Main finished of mission is: 1、 manufacture to realize ether net with the spot of Lonworks total the 100 M/10M agreement conversion machine;2、complete the total line in the spot of Lonworks and intelligence the RS485 that gauge need when connecting with each other mold piece;3、realize the total line in the spot of Lonworks equip with PLC to link mutually.
Key Word:fieldbus, correspondence, the network connects,RS-485
