Weiming Tong · Ha'erbin gongye daxue xuebao · 2004
The features, application background and the basic technology of DeviceNet, ControlNet and EtherNet/IP are studied.Functions, constitution and implementation of CIP in NetLinx are introduced.MAC mechanism of each network of NetLinx is described, such as the CSMA/AMP(Carrier Sense multiple Access with Collision Detection/Arbitration Message Priority) mechanism of DeviceNet, the implicit token-passing mechanism of ControlNet and the CSMA/CD (Carrier Sense multiple Access with Collision Detection) mechanism of EtherNet/IP. NetLinx is an effective resolvent to solve the interconnection of different industrial network and implement effective, fast and reliable data transmission and seamless control data flow and information flow.
