Abstract
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.
Claims11
A relay device that relays data between a control device and a plurality of devices that are control targets of the control device and operates in accordance with setting information, the relay device comprising:
- a receiving unit that receives an instruction for executing backup of acquiring the setting information from the devices and storing the acquired setting information in a storage unit or an instruction for executing restoring of transmitting the setting information stored in the storage unit to the devices and storing the setting information in the devices;
- and
- a setting information processing unit that executes backup of the plurality of devices or executes restoring of the plurality of devices in accordance with one instruction received by the receiving unit.
A control method for a relay device that relays data between a control device and a plurality of devices that are control targets of the control device and operates in accordance with setting information, the control method comprising:
- a receiving step of receiving an instruction for executing backup of acquiring the setting information from the devices and storing the acquired setting information in a storage unit or an instruction for executing restoring of transmitting the setting information stored in the storage unit to the devices and storing the setting information in the devices;
- and
- a setting information processing step of executing backup of the plurality of the devices or executing restoring of the plurality of the devices in accordance with one instruction received in the receiving step.
(canceled)
A non-transitory computer-readable recording medium, storing a control program for causing a computer to execute a control method for a relay device configured to relay data between a control device and a plurality of devices being control targets of the control device and operating in accordance with setting information, wherein the control method comprises:
- a receiving step of receiving an instruction for executing backup of acquiring the setting information from the devices and storing the acquired setting information in a storage unit or an instruction for executing restoring of transmitting the setting information stored in the storage unit to the devices and storing the setting information in the devices;
- and
- a setting information processing step of executing backup of the plurality of the devices or executing restoring of the plurality of the devices in accordance with one instruction received in the receiving step.
