Method for continuous analysis of the transmission quality in fieldbus networks
First Claim
1. A method for continuous analysis of transmission quality in a fieldbus network having a bus examiner and a plurality of participants communicate with one another over the fieldbus network, the bus examiner executing the method comprising:
- measuring at least one of logical and physical bus parameters from signals transmitted between at least two of the plurality of participants over the fieldbus network;
storing the measured bus parameters; and
deriving first operational parameters from the measured bus parameters,wherein each first operational parameter is formed by linking at least two of the weighted bus parameters, andwherein the weighting of a first bus parameter of the measured bus parameters is determined by at least one other measured 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 having a bus examiner and plural fieldbus participants, the bus examiner executing the method comprising:
-
measuring logical and physical bus parameters from a line signal transmitted between at least two fieldbus participants over the fieldbus network, and storing the measured parameters, weighting a plurality of the measured bus parameters; deriving operational parameters from the measured bus parameters based on at least one of the weighted bus parameters, the weighted bus parameters being linked together to form each operational parameter, and determining a weighting of a first bus parameter of the measured bus parameters by at least one other measured bus parameter.
