The authors adduce a way of formation of a code with summation, that is based on the weighting of transitions between adjacent bits in data vector and operations with transitions weight indexes. The consequence has been established for weight indexes and simple rules of modification of the code with summation of weighted transitions that allow us to form optimal, from the point of view of the minimumnumber of data bits undetectable errors, codes. It is shown that new codes allow organizing the concurrent error detection systems with lowered redundancy.
