iCAN series functional module theory and its application in lifting moment restriction system

Considering the present condition that the rapid development of domestic application of field-bus technology in China,this paper intends to discuss the fieldbus control systems—iCAN system and the latest application-layer protocol—iCAN protocol based on CAN-bus,and to point out both the ad-vantages and the development space of the iCAN system and protocol,by the comparison with other CAN-bus-based systems and protocols.This paper mainly focuses on the theory of iCAN series func-tional module,following with illustrative diagrams of the theory and the applied examples in lifting mo-ment restrictions system,combining with the present industrial applications.
