A network apparatus (), when connecting to a communication network (), broadcasts a first address search frame that includes an address and priority of the network apparatus (), and, upon receiving a second address search frame that is broadcast by another apparatus during connection to the communication network, returns a first return frame that includes the priority of the network apparatus () if there is an address overlap with the network apparatus ().

System for detecting and handling overlapping addresses based on priority

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 () is provided with: a display control part () for causing a display part () to display an event log; an identification part () for identifying an event of interest log specified by a user through an operation part (); and an extraction part () for extracting a related event log related to an event of interest from an event log database (). The display control part () causes the display part () to display the event of interest log and the related event log.

Information processing device, control method, and recording medium for specifying related event from collected event logs

A control device includes a cyclic communication part and a communication management part. A cyclic communication part controls communication of first control data of which arrival in a first guarantee time is guaranteed according to a preset cyclic period and second control data of which arrival in a second guarantee time longer than the cyclic period is guaranteed and of which a sequence of information included is determined. The communication management part manages a communication schedule of first control data and second control data. When new second control data is acquired while the second control data is divided into a plurality of communication data and communicated according to the cyclic period, the communication management part determines a communication sequence of the plurality of second control data according to priorities of the plurality of second control data.

Control device, control system, control method, and non-transitory computer-readable storage medium

A control device includes a cyclic communication part, a message communication part, and a communication management part. The cyclic communication part performs communication according to a preset cyclic period. The message communication part performs communication that need not conform to the cyclic period. The communication management part manages a communication schedule for the cyclic communication part and the message communication part. When it is detected that control data scheduled to be communicated is data for preferentially selecting communication in the cyclic communication part, the communication management part detects a communication state of the cyclic communication part. When cyclic communication is possible, the communication management part stores the control data in the cyclic communication part, and when cyclic communication is not possible, the communication management part stores the control data in the message communication part.

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.

To reduce the working hours of a user in an operation and improve an operation rate in an industrial network system. A communication setting change part is provided which automatically changes, in a timing of an end effector replacement, the communication setting in a communication part according to the communication information that corresponds to an end effector.

Slave device, master device, and industrial network system

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.

Communication system, communication device, and communication program

The invention relates to a signal processing device, a signal processing method, an information processing program and a recording medium, which removes wide-range frequency noise. In a signal processing device (), a cycle of acquiring a signal from a sensor is a data acquisition cycle, which is shorter than a cycle of forwarding time sequence data from which noise is removed to a controller, that is, a forwarding cycle.

Signal processing device, signal processing method, information processing program and recording medium

The invention relates to a signal processing device, a control method thereof, a control procedure and a recording medium, which is unnecessary to increase a memory capacity for implementing sampling to determine a filter parameter. The signal processing device includes a data acquiring element (), acquiring signals of a time series, i.e. time series signals from a sensor; a filtering element (), performing a filtering operation according to frequencies; a transfer element (), transferring the time series signals; and a filter parameter determination element (), performing frequency analysis to the time series signals within a pre-specified interval, i.e. a specified interval to determine a filter parameter.
