Forms of automatic error diagnosis routines

Automatic error diagnosis is utilized by several hardware configuration components. A typical application is the installation of Central Processing Unit (CPU) circuitry to diagnosis data parity errors identified in the CPU and linked storage areas. Furthermore, the CPU may have self-diagnostic capabilities to reveal defective circuitry or memory. In some instances, as a corrective measure, the CPU may be able to route operations and storage around defective configuration components.

Automatic error diagnosis is also utilized to identify faulty magnetic tape read/write heads. In this scenario, the CPU checks the read/write head during an assigned task to ensure that the current is flowing through the device. With a positive check, it is assumed that reading and writing is taking place during inspection. Conversely, with a negative check, it is assumed that reading and writing is not taking place during inspection.
