A method for operating an object-based configuration system CS for field devices of automation technology, with a frame application FA, which serves for managing and instantiating a plurality of objects, wherein, to individual groups of device objects, field device types are assigned, which enable, as device managers, a configuration of the corresponding field device type. A first main object MO-1 is provided, which makes available a first object set OS-1 with device objects for a plurality of device types and instantiates, with the help of a first control engine, via an identifier ID, device objects of the first object set, in order to produce device managers for these field device types. Besides the first main object MO-1, a second main object MO-2 is provided, which has a second object set OS-2, wherein individual device objects of the second object set OS-2 are updated device objects of the first object set OS 1. Between the frame application FA and the main object(s) MO-1, MO-2, respectively, an intermediate layer I is provided, which selects, via a second control engine, that main object, which makes available the updated device objects for the selected device type, and which, following selection of the device type, transfers to the corresponding main object the identifier ID, in order to instantiate the updated device object.
