Computer network at the Dukovany nuclear power plant

Briefly presented are the main components of computer technology which will be available at the nucler power plant in Dukovany at the time of commissioning all four units. All equipment is to operate in the planned computer network. The central computer VK-2M45 basically represents two basic units, each of which has its own 4 MB main memory. It is stated that the relatively good hardware provision of the two-processor complex so far has not found an equivalent software. Each processor is controlled by an independent operating system and basically operated as an independent computer. Reasons are given for the interconnection of the different components of computer technology and factors are summed up which have affected the choice of suitable network architecture. The choice has narrowed to the DERIS-900 system and the architecture of open systems. (Z.M.)
