Wire Tension System Based On The Profibus-dp Bus Design And Research

PROFIBUS agreement structure is according to ISO7498 international standard, It is regarded as model of consulting with the open systematic internet (Open System Interconnection-SIO). This model has seven layers.PROFIBUS-DP is used in the high-speed data transmission on storey of scene, Besides periodic user's data transmission, PROFIBUS-DP offers the non-periodic communication that the intelligent apparatus needs in order to carry on the configuration. Diagnose and call the police and deal with.For the RS-485Transmission technology, The Potter rate is from 9.6K bit/s to 12M bit/s, Support the single main fact or main system more. Bus stand more, it counts to be 126 most.This paper presents an application of Steel Cord Drawing Distributed Control System Based on PROFIBUS-DP designed by the FCS controlling mode connecting HMI with PLC and Drivers. Combining FCS with configuration programmable skill, the control system can run independently with the supervising computer or the local equipment. With the design, both the credibility and efficiency of the system and the quality of product can be improved. It also provides preferably references for the designs of other preparation control systemsA detailed discussion on the MAC mechanism of PROFIBUS-DP is given in the paper. The model of message transmission among master stations and that between master and slave stations is set up to analysis the network throughput and time parameters, through which the real-time property, determinism and network utility of the PROFIBUS-DP is presented and meaningful conclusions drawn that helps to the integration and configuration of industrial communication system with PROFIBUS-DP.
