Design of a Remote Maintenance System for ABB Drives

ABB drives are widely used in metallurgical mining,windmill farms,building automation and oilfields.Therefore,rapid diagnosis and maintenance technologies that ensure security and reliability of the driving system is obviously important.Remote maintenance systems supported by computer,communication,network and multimedia technologies provide safe,efficient and convenient way to maintain the product remotely.This paper focuses on building a maintenance system for ABB drives,which integrates remote monitoring,control and diagnose.The design of hardware allows the configuration for DTU,PLC and ABB drive units.The communication between DTU and PLC is realized via RS485.The group control between PLC and drives is realized via RS485 and MODBUS.The software allows coding of the host server,programming of PLC and WEB interface design for mobile devices.
