A control device configured to control an industrial machine, the control device having: a plurality of memories including a first memory configured to hold data when a power supply is off and a second memory configured to inhibit data from being held when the power supply is off; and circuitry configured to: set, in each of a plurality of data units, an attribute indicating whether the data unit is to be held when the power supply is off; and set an address of each data unit such that each data unit is stored in one of the plurality of memories corresponding to the attribute.

Control device with attribute setting for industrial machine, attribute setting system for control device for industrial machine, method of setting control device with attributes for industrial machine, and information storage medium for setting a control device with attributes

An industrial device communication system comprising: industrial devices that function as communication masters; industrial devices that function as communication slaves that receive control data from the industrial devices that function as communication masters; communication lines that communicably connect the industrial devices to one another; one or more switches for causing a communication group including the industrial devices that function as communication masters and the industrial devices that function as communication slaves to communicate independently from one or more other communication groups; and one or more switch controllers that control the one or more switches, causing the switches to switch between a state in which an inter-group communication line present between the communication group and the one or more other communication groups is disconnected, and a state in which the disconnected inter-group communication line is connected, according to the communication group that independently communicates in each of periods.
