Abstract
Disclosed is a diagnostic unit for a remote diagnosis of a data processing unit (DPU). The diagnostic unit is adapted to be coupled to a remote DPU via a network and to an internal bus of the DPU. The diagnostic unit includes a central processing unit (CPU) for controlling a diagnostic action and/or a monitoring action independently of the DPU, by monitoring a data communication within the DPU and/or of the DPU with external devices, and/or by performing tests with the DPU. An “intelligent” diagnosis of the DPU can thus be provided, allowing a continuous and on-going monitoring of the DPU independent of the functional state of the DPU.
Claims14
A diagnostic unit for a remote diagnosis of a local data processing unit (DPU) having a first central processing unit (CPU), said diagnostic unit coupled to a remote DPU via a network and to said local DPU via an internal bus, said diagnostic unit comprising:
- a second central processing unit which is independent of said DPU and said first CPU, wherein said second CPU is capable of controlling at least one of a diagnostic action or a monitoring action, independently of said local DPU, by monitoring at least one of a data communication within said local DPU or a data communication by said local DPU with external devices, or by performing tests on said local DPU.
A method for providing a remote diagnosis of a local data processing unit (DPU) having a first central processing unit (CPU), said method comprising:
- coupling a diagnostic unit having a second CPU independent from said local DPU and said first CPU to an internal bus of said local DPU,
- monitoring at least one of:
- a data communication within said local DPU or a data communication of said local DPU with external devices, or performing tests on said local DPU,
- coupling said diagnostic unit to a remote DPU via a network, and
- providing a signal to said remote DPU indicating a functional state of said local DPU.
A diagnostic unit for remote diagnosis of a local data processing unit (DPU) having a local central processing unit (CPU), said diagnostic unit comprising:
- a remote central processing unit adapted to be coupled to a remote DPU via a network and to said local DPU via an internal bus;
- wherein said diagnostic unit controls at least one of a diagnostic action or monitoring action of said local DPU, independently of said local CPU, by monitoring at least one of a data communication within said local DPU or a data communication by said local DPU with external devices or by performing tests on said local DPU by means of said remote CPU.
