Abstract

A method is disclosed for continuous analysis of the transmission quality in fieldbus networks in automation systems with a plurality of fieldbus participants, which communicate with one another over the fieldbus network. Directly measurable logical and physical bus parameters are recorded from the line signal transmitted over the fieldbus network, and are stored with a predefinable retrospectivity. Operational parameters are derived from the measured bus parameters, these being weighted and the weighted bus parameters being linked together to form the operational parameter. The quantitative weighting of a bus parameter is functionally determined by at least one other bus parameter.
