Abstract: An information processing device (20) is provided with: a statistical information acquisition unit (211) which acquires statistical information about communication with another machine connected by a cable; an abnormality determination unit (212) which refers to the statistical information acquired by the statistical information acquisition unit (211) and determines an abnormality in the communication; and an abnormality notification unit (213) which notifies a master device of the determination result, when the determination result from the abnormality determination unit (212) indicates that the communication is abnormal.

Abstract: The purpose of the present invention is to enable even an unskilled person to easily identify a related event in a short time from a collected event log. A system management device (1) is provided with: a display control part (32) for causing a display part (14) to display an event log; an identification part (30) for identifying an event of interest log specified by a user through an operation part (11); and an extraction part (31) for extracting a related event log related to an event of interest from an event log database (20). The display control part (32) causes the display part (14) to display the event of interest log and the related event log.

Abstract: A sensor support system includes a sensor and a terminal device configured to display form information of the sensor. The sensor includes a two-dimensional code (storage tag) which can be read from the terminal device and which is configured to store the form information of the sensor. The terminal device is configured to calculate position information of the sensor from an image of the sensor, configured to generate a virtual image of the form information of the sensor, and configured to display on a display an image in which the virtual image is superimposed on an image of the sensor taken by a camera.

Abstract: A communication system includes a communication device functioning as a master device and a plurality of slave devices communicably connected to the communication device via a communication line, the communication device setting a prescribed address in an added slave device based on a position of the added slave device in a topology composed of a plurality of slave devices, judging whether a change has possibly occurred in the topology when the prescribed address is set in the added slave device, if there is an erroneously set slave device whose address was erroneously set, specifying that slave device, when it is judged that a change has possibly occurred, and resetting the address of the specified erroneously set slave device to an original address.

Abstract: A slave device is realized that establishes a link with a master device or another slave device such that a large link delay hardly occurs. The slave device includes a PHY unit, a COM unit, and a MPU unit. The PHY unit starts an operation according to the specification of the AutoMDI/MDI-X function when the slave device is turned on or the PHY unit itself is reset. After a predetermined time period has elapsed, the MPU unit resets the COM unit, and the PHY unit is reset in response to the reset of the COM unit.
