Developing universal protocol for distributed control applications with microcontrollers

This paper describes a new industrial communicatio n protocol, dNet protocol suite, and its application in control systems. Protocols in this s uite have some useful properties known from higher communication protocols. For example, abstract of a ddresses and connection, encryption and application services. They also have some characteristics typic al rather for industrial protocols, e.g. simple implementation in microcontrollers, compatibility w ith existing bus standards (CAN), support for program downloading and device configuration. The s uite can be operated almost over any data link layer. Document then presents a typical way of prot ocol usage, definition of application services and networks management.
