Implementation of fully integrated automation with Profibus

This paper presents an integrated approach for implementing fully automation with Profibus technology. We studied the frame of Profibus protocol and the communication model for Profinet components. A scheme for developing Profibus slave was proposed. Aiming at the interoperation between Profibus devices and other fieldbus devices, a scheme for designing fieldbus protocol conversion gateway was also presented. Other kinds of fieldbus devices can connect with Profibus network via the gateway. Profibus devices can be directly encapsulated in Profinet components, and through a gateway, other kinds of fieldbus devices can also be encapsulated with Profinet.
