Method for continuous analysis of the transmission quality in fieldbus networks
First Claim
1. A method 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,whereindirectly measurable logical and physical bus parameters are recorded from the line signal transmitted over the fieldbus network, and are stored with a predefinable retrospectivity,that 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 andthat the quantitative weighting of a bus parameter is functionally dynamically determined by at least one other bus parameter.

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.

12. A method for continuous analysis of a transmission quality over a fieldbus network, comprising:
-
measuring logical and physical bus parameters from a line signal transmitted over the fieldbus network, and storing with a predefinable retrospectivity, deriving operational parameters from the measured bus parameters based on weighted bus parameters, the weighted bus parameters being linked together to form the operational parameter, and functionally dynamically determining quantitative weighting of a bus parameter by at least one other bus parameter.
