Mini-DCS containing process stations, operator stations, and engineering stations are considered in the paper. Process stations provide the control of the process. Operator stations are designed to process visualization, as well as to the operator interaction. Configuration of the system and supervision of the communication process are carried out at the engineering stations. Between the stations of the system, the process data are transmitted. The fitness of the control process depends on correct transmission of the data with process values. Anti-destructive processes are responsible for the correctness of the received data. Fitness of the communication system determines the fitness of the entire control system. The article contains considerations relating to dependency of integrity and confidentiality of the transmitted data on the level of fitness of communication system connecting the stations.Keywords: fitness, integrity, confidentialit
