Patent ID: 8433827

Claim:
A method for configuring fieldbus stations in a subnetwork, the method comprising: forming a first system setup from fieldbus stations of a first subnetwork; providing a first fieldbus station of the first subnetwork with an executable user program; establishing rules in the first system setup comprising: i) defining a reference point from which address data for configuring the fieldbus stations in the first subnetwork is derived; ii) choosing a setting for a station name and an address of the fieldbus stations indicating which address data will be assigned at a later point in time; and iii) temporarily setting, with an exception of the first fieldbus station, further fieldbus stations as deactivated; starting the first fieldbus station and executing the user executable program; and executing a sequence in the user executable program comprising: iv) reading in of a data record from the reference point, a reference name and a reference address being determined by the data record; v) deriving station names and station addresses for the fieldbus stations from the reference name and the reference address; vi) invoking a system function in the user executable program which writes the derived station names and station addresses to a configuration file; and vii) activating all previously deactivated fieldbus stations.
