Abstract Aiming at the problems of low control precision and complex process in electrical engineering automation control, this paper proposes a kind intelligent technology based on DeviceNet. This focuses development process, communication protocol object modeling method DeviceNet universal I / O interface microprocessor. At same time, designs application layer software, gives detailed hardwar...

The term ‘interoperability’ has been mentioned in various electronic communications fields. In short it represents the “ability to operate between parties”. ‘Interoperability’ is sometimes defined as “how data is effectively exchanged and utilised between devices”. This statement reflects only the situation in the Application Layer. Interoperability should be the concern of all layers. In Devic...

Ethernet for industrial communications Unlike office communications, industrial and process automation are based on a multitude of different fieldbus systems (e.g. ASI, CAN, DeviceNet, Interbus, LON, PROFIBUS). Particular versions with additional performance features have established themselves in parallel for specific applications such as drive technology or safety technology. Generally, these...

DeviceNetTM and ControlNetTM are two well-known industrial networks based on the CIP protocol (CIP = Control an Information Protocol). Both networks have been developed by Rockwell Automation, but are now owned and maintained by the two manufacturer's organizations ODVA (Open DeviceNet Vendors Association) and ControlNet International. ODVA and ControlNet International have recently introduced ...

The Allen-Bradley ControlLogix [1] line of programmable logic controllers (PLCs) offers several interfaces: Ethernet, ControlNet, DeviceNet, RS-232 and others. The ControlLogix Ethernet interface module 1756-ENET uses EtherNet/IP, the ControlNet protocol [2], encapsulated in Ethernet packages, with specific service codes [3]. A driver for the Experimental Physics and Industrial Control System (...

Since Autonomous Decentralized Systems have been proposed in 1977 and published [1], their technologies and applications in control and information fields have progressed and some of their technologies are approved as the de-facto standards of ODVA (Open DeviceNet Vendor association), OMG (Object Management Group), etc. Recently the ADS have been accelerated more under the unpredictable recent ...
