Abstract
Important reasons for connecting fieldbus systems to IP-based
networks are the provision of remote access for monitoring and
maintenance purposes, but also the inclusion of automation systems into
an enterprise-wide management scope. Existing solutions are chiefly
based on Web technology or require specialized, fieldbus-dependent
tools. In this paper, the authors propose a different strategy using the
standardized and widely used Simple Network Management Protocol. This
approach is largely fieldbus-independent and, at the same time,
interoperable with existing LAN technology. They discuss the
architecture of a protocol conversion gateway and present a modular
approach to cope with the variety of available fieldbus protocols. They
further propose a structure for a management information base suitable
to represent the fieldbus data objects. By means of prototype
implementations for different fieldbus systems (Profibus, P-NET, and
EIB), they study the influence of the underlying fieldbus communication
principles on the gateway implementation and operation
