Developing universal protocol for distributed control applications with microcontrollers

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