This diploma thesis deals with the optimization of the process of matching the bearing components. The work contains a description of Codesys programming environment, its structure, usable languages and some examples of usage. The main part of the thesis describes a series of algorithms that provide the necessary actions for one of two processed pairing approaches. These algorithms are subsequently implemented as subprograms in the Codesys environment. The necessary inputs and outputs are part of the proposed algorithms as well as processed subroutines.
