ABSTRACT:
There is disclosed a diagnosis system for a data processing system including at least one transmitter member having a first storing means for storing a first set of processing programs, a data processing unit having means for selectively executing the first set of processing programs, a receiver member having second storing means for storing information resulting from the execution of the first set of processing programs and a checking circuit for testing the execution of the first set of processing programs in response to test data supplied to the data processing unit. In particular, the diagnosis system comprises diagnosis means and an input/output circuit connectable to said checking circuit and to said diagnosis means. The diagnosis means, more specifically, includes a third storing means for storing a second set of diagnosis programs related to the diagnosis of the data processing unit, the transmitter member and the receiver member. Processing means is provided for executing the second set of diagnosis programs to provide test data to be transferred and stored in the second storing means, whereby a defective component within the data processing system may be ascertained, both before and during the processing of data by the data processing unit.
