[en] The programs have a modular structure and operate in real time, and user programs are divided into the following groups: information on the disk system, measurement of diagnostic signals, identification of immediate state, data interpretation, communication between different parts of the system. The system's software contains operation systems, diagnostic, service and loading programs, user software includes disk and non-disk operation system programs. The properties of certain program groups are summed up as are the methods used for selecting the required functions. The described software is capable of providing the complex operation of hardware for measuring and partial diagnostics and will be put into operation at the Dukovany nuclear power plant. (J.C.)
