The article deals with the discrete model of the corrective system, which can detect single errors that occur when reading data coming from the rotary device angle sensor. To minimize errors that may occur when converting turn angle data into digital code an 9-bit protected Frank Gray code using is proposed when the coding is in process. A test bit is added to the code combination to detect single errors that may occur when there is noise in the transmitting channel. The information that comes to the computer input is converted into binary code for further processing and storage in the file system. To minimize errors an algorithm for combined information coding is proposed. The algorithm is based on the logical operation containing the sum module 2. To investigate the corrective properties of the protected Frank Gray code, we use the rewrite system. To simulate the functions of encoding and decoding devices we use the cellular automaton that generates a sequence of binary code combinations according to the rules set by the rewrite system. A corrective system is modeled in the Wolfram Mathematica computer environment.
