System design of diagnostic subsystem in control networks

The current development of computer control and associated diagnosis has been made possible by the advent of microcomputers and microprocessors. This leads to the introduction of distributed systems based on the division of the whole system into partial, autonomous, interlinked subsystems each with its own control processor. Thus, improved system flexibility and reliability can be attained and a better solution to both control and diagnostics tasks is achieved. Dividing the tasks and bringing them closer to partial technological assemblies increases the rate of data processing; failures of a local processor do not necessitate putting the entire equipment out of operation. Diagnostic tasks are discussed in the present study of the 0th and 1st levels of the hierarchial division of the processor network.
