Abstract
There is provided a device including: a diagnosis unit configured to diagnose an input and output function, in an input and output device that is configured to perform an input and output operation in accordance with the input and output function programmed in programmable circuitry; an error detection unit configured to detect an error of a configuration storage area; and an abnormality determination unit configured not to determine an abnormality of the input and output device when the error of the configuration storage area is detected and the input and output function is diagnosed to be normal.
Claims19
A device comprising:
- a diagnosis unit configured to diagnose a programmed input and output function, in an input and output device that has programmable circuitry of which a circuit configuration is programmed by setting configuration data and that is configured to perform an input and output operation in accordance with the input and output function programmed in the programmable circuitry;
- an error detection unit configured to detect an error of a configuration storage area in which the configuration data is stored;
- a determination unit configured to determine whether the input and output device is multiplexed, and
- an abnormality determination unit configured not to determine an abnormality of the input and output device, on condition that the input and output device is not multiplexed when the error of the configuration storage area is detected and the programmed input and output function is diagnosed to be normal.
A method comprising:
- diagnosing a programmed input and output function, in an input and output device that has programmable circuitry of which a circuit configuration is programmed by setting configuration data and that is configured to perform an input and output operation in accordance with the input and output function programmed in the programmable circuitry;
- detecting an error of a configuration storage area in which the configuration data is stored;
- determining whether the input and output device is multiplexed;
- and
- not determining an abnormality of the input and output-device on condition that the input and output device is not multiplexed when the error of the configuration storage area is detected and the programmed input and output function is diagnosed to be normal.
A non-transitory computer-readable storage medium having stored thereon a program that causes a computer to execute:
- diagnosing a programmed input and output function, in an input and output device that has programmable circuitry of which a circuit configuration is programmed by setting configuration data and that is configured to perform an input and output operation in accordance with the input and output function programmed in the programmable circuitry;
- detecting an error of a configuration storage area in which the configuration data is stored;
- determining whether the input and output device is multiplexed;
- and
- not determining an abnormality of the input and output-device, on condition that the input and output device is not multiplexed when the error of the configuration storage area is detected and the programmed input and output function is diagnosed to be normal.
