Annotation:
The article analyzes the methods of formation of codes with the summation of data bits. It is noted that the well-known modular codes with summation (either residual codes or Bose-Lin codes) are not the only class of codes with low redundancy that can be used in solving problems of technical diagnostics and synthesis of test-able digital systems. The concept of multi-module code with summation and its subclass – two-module code is introduced. The results of studies of two-module codes with summation are presented, the advantages and disadvantages of two-module codes with summation are noted. The classification of codes with the summation of data bits is given.

Key words:
technical diagnostics, digital systems, code with summation, Berger code, modular code with summation, Bose-Lin code, two-module code, data vector, error in the data vector
