Abstract

A method for configuring and operating a read/write unit connected to an industrial control device in a system including multiple transponders having unique identification numbers, the read/write unit. During a recognition phase, a plurality of the transponders are detected, at least two of the transponders are repeatedly detected, and during each detection, the unique identification number of each detected transponder and a number of features relating to each detection of that transponder are registered. During an evaluation phase, the registered features are evaluated statistically for each detected transponder, statistical variables are determined for each detected transponder, and the statistical variables are respectively filtered using filter criteria. The unique identification number of one of the detected transponders that meets the filter criteria is reported to the industrial control device as a detected transponder to provide unambiguous identification of the closest transponder to the read/write unit, even in densely packed surroundings.
