The present invention addresses the problem whereby the number of commands to be transmitted increases in accordance with an increase in the number of devices to be backed up and restored, and processing becomes complex. An IO-Link master is provided with: an upper-level communication control unit which receives an instruction to execute backup in which setting information is acquired from IO-Link devices, and stored in a storage unit; and a backup control unit which executes backup of the plurality of IO-Link devices in accordance with the one received instruction.

Relay device for relaying data between devices, control method therefor, and non-transitory computer-readable recording medium therefor

The purpose of the present invention is to stop the power supply to a specified device among a plurality of devices to be supplied with power, and maintain the power supply to the other device. An IO-Link master is provided with: an upper-level communication control unit which receives a specification of a device to which the power supply is to be stopped; and a power supply control unit which controls a device power supply switching unit corresponding to the device to which the power supply is to be stopped, to stop the power supply to said device while maintaining the power supply to the other device.

Relay, control method, and non-transitory computer-readable recording medium for power supply control

A device is easily exchanged without changing a program of a controller. A device communication management unit generates digital input data that stores only ON/OFF information of a device in accordance with a copy setting information table set by a user.

Slave device, control method of slave device, non-volatile computer readable recording medium

The present invention aims to reduce an operation burden related to the change of reception processing in a master device when a device connected to a slave device is changed. A device communication managing unit () transmits the data received by a device () communicating with a device communication port () in a first mode to a field network () by using a data format used for transmitting the data received by the device () communicating in a second mode.

Slave device, control method of slave device, information processing program and recording medium

In order to reduce the labor required in order for a user to manually input and register the identification information of a device scheduled to be connected to a slave device, a device communication management unit () generates configuration settings information that includes the identification information of a device () scheduled to be connected to a device communication port (), on the basis of the identification information of the device () connected to the device communication port ().

Slave device, method for controlling slave device, and non-transitory computer-readable recording medium

An IO-Link master includes: an IO-Link communication port that communicates with an IO-Link device according to a predetermined communication protocol; a digital input port that receives a first signal value output from the IO-Link device; and a determiner that determines whether abnormality is generated in a digital input line connecting the digital input port to the IO-Link device based on a second signal value received with the IO-Link communication port and the first signal value.

Control system, control method, control program, and recording medium

A communication system is formed with a master unit having a communication function and at least one slave unit also having a communication function connected by a network including a bus. Repeater units are inserted on the network between the master unit and the slave unit in one or more stages. As the master unit transmits request frames downstream through the network to the slave unit, the slave unit control the timing of transmitting the response frames in response successively such that the master unit receives the response frames without waiting in between regardless of repeater delay times of each of the returned response frames determined by the number of stages of the repeater units. Each communication frame that is transmitted through the network contains identification data indicative of its type and each repeater unit serves to repeat certain types of received frames only in the upstream direction.

Communication system and slave and repeater units therefor

A programmable-controller remote terminal apparatus of the invention shortens a system down time generated in replacing an I/O unit, in the I/O unit having a three-divided configuration of a remote terminal apparatus in which miniaturization and low-profile are developed. A programmable-controller remote terminal apparatus, which is connected to a programmable controller through a fieldbus, includes a communication unit and at least one I/O unit which can communicate with the communication unit through a serial bus line, wherein the communication unit has a device which obtains unit information for identifying each connected I/O unit and setting value information set in each I/O unit, and the communication unit has a backup device which can store the obtained unit information and setting value information of each I/O unit in a storage medium included in the communication unit.

Remote terminal apparatus for programmable controller

An inverter has a measuring part that measures an operating time such as the time interval from when a command to start a specified operation by an associated system until a signal indicating the completion of the operation is received. A comparing part compares this measured operating time with a threshold value stored in a memory and an abnormal condition is reported to a host system, depending on the result of the comparison.
