Abstract: An industrial automatic-diagnostic device connected to an FA system in which a plurality of FA devices are connected to each other, the industrial automatic-diagnostic device includes: an engineering tool; and a display unit. Based on interface connection information and device configuration information of a corresponding FA device held by each of the FA devices, the engineering tool creates overall configuration information of the FA system and displays an overall configuration of the FA system on the display unit based on the overall configuration information. When an abnormality occurs in the FA device, diagnosis information about an abnormal part self-diagnosed by the FA device and abnormality contents with respect to the abnormality occurred in a corresponding abnormal part is obtained. Based on the obtained diagnosis information, occurrence of an abnormality is displayed in an abnormal part in an overall configuration of the FA system displayed on the display unit.

Abstract: The invention includes a read-restriction setting step of setting read restriction on a program stored in hardware of an industrial product in response to a read restriction request, and a read requesting step of transmitting a read request for the program to the industrial product from an engineering tool that is a read request source. In the read-restriction setting step unique individual information retained in the hardware of the industrial product or unique individual information retained in hardware for executing an engineering tool that is a read-restriction request source is registered as registration individual information, and in the read requesting step, unique individual information retained in hardware for executing the engineering tool that is the read request source or unique individual information retained in the hardware of the industrial product is compared with the registration individual information.

Abstract: To provide an engineering tool including a basic processing unit that performs a process of program editing according to an input operation by an input device, and a display processing unit that displays an operation screen for the program editing on a display device. The basic processing unit can accept the input operation by a plurality of input devices, as a plurality of human interfaces, and when a human interface corresponding to a level of operation skill in the input operation is selected from the human interfaces, the basic processing unit performs a process in accordance with the input operation by an input device corresponding to the selected human interface, and the display processing unit displays the operation screen corresponding to the selected human interface on the display device.

Abstract: An apparatus for measuring nuclear reactor power distribution comprises a Fourier coefficient calculation means and a transformation means, whereby Fourier coefficients of neutron detector outputs are transformed into Fourier coefficients of integrated values of the reactor power on each interval, and hence conditions required of data for initial calibration are made less severe and the initial calibration is enabled to be performed much easier. The apparatus further comprises an abnormal data deletion means, whereby detection and deletion of abnormal data are made easy so that the apparatus performs a stable operation with high accuracy.

Abstract: In a storage unit equipped with a Reliablity, Availability and Serviceability (RAS) circuit, including a memory unit constructed of, e.g., a dynamic random access memory (DRAM) unit, for storing data with an error coding code (ECC), and an ECC unit constructed of e.g., an ECC checking circuit, for correcting a 1-bit error and detecting a 1-bit error, or more than 2-bit error contained in the data read from the memory unit, an ECC diagnostic unit is connected between said memory unit and said ECC unit, and an error made concerning the memory unit and ECC unit is diagnosed by the ECC diagnostic unit by selectively inverting the data read from the memory unit into diagnostic data during the checking operation of the ECC units to diagnose proper operation of the ECC unit and detect erros.
