Patent ID: 8793366

Claim:
A method for diagnosing networks including networks of field bus systems utilizing an arrangement for diagnosing said networks which includes at least two field bus diagnostic apparatuses with each of said field bus diagnostic apparatuses being assigned to a corresponding field bus, the method comprising the steps of: causing each of said field bus diagnostic apparatuses to detect current data traffic of the corresponding one of said field busses as a data record and storing said data record on an allocated storage medium; diagnosing the detected data record in an evaluation unit integrated into the corresponding field bus diagnostic apparatus and storing the diagnosed data record in the storage medium allocated to the corresponding field bus diagnostic apparatus; making the detected, diagnosed and stored data record available across said networks via a server integrated into each of said field bus diagnostic apparatuses; causing said field bus diagnostic apparatuses to exchange said data records with each other via the server integrated into each of said field bus diagnostic apparatuses and across said networks and storing the exchanged data records on the storage mediums of corresponding ones of said field bus diagnostic apparatuses so that, on each of said storage mediums, the exchanged data records of all other field bus diagnostic apparatuses are stored in addition to said detected, diagnosed and stored data records of the field bus diagnostic apparatus; and, inspecting the detected, diagnosed and stored data records via at least one output unit with each output unit being connected via a client to a network of said networks and said data records being made available in said network by at least one arbitrary server.
