Production system, recovery system, production method, and information storage medium

A recovery system, comprising a circuitry, the circuitry being configured to:

• detect a change of a plurality of start variables that correspond to the plurality of recovery processes,
• start each of a plurality of recovery process when the recovery system detects the change in the corresponding start variable;
• detect an abnormality that has occurred in an industrial machine configured to execute each of a plurality of processes when the industrial machine executes any one of the plurality of production processes;
• receive a specification from a controller of one or more recovery processes to be executed in order to perform recovery, based on a first recovery process information associating, for each of the plurality of recovery processes, at least a name of the each of the plurality of recovery processes with the start variable representing an operation of the industrial machine and indicating the change is to be performed by a recovery process program to be executed in the each of the plurality of recovery processes, when the abnormality is detected;
• and
• record a second recovery process information indicating one or more start variables of the received one or more recovery processes;
• wherein the controller is separated from the industrial machine and the controller is external of the industrial machine;
• and
• wherein the controller communicates with a plurality of industrial machines including the industrial machine via a network communication.

A production method to be performed by an industrial machine configured to execute each of a plurality of recovery processes and each of a plurality of production processes, the production method comprising:

• detecting a change of a plurality of start variables that correspond to the plurality of recovery processes, and
• starting each of the plurality of recovery process after detecting the change in the corresponding start variable,
• detecting an abnormality that has occurred in the industrial machine when the industrial machine executes any one of the plurality of production processes;
• receiving a specification of one or more processes from a controller to be executed in order to perform recovery, based on a first recovery process information associating, for each of the plurality of recovery processes, at least a name of the each of the plurality of recovery processes with the start variable representing an operation of the industrial machine and indicating the change is to be performed by a recovery process program to be executed in the each of the plurality of recovery processes, when the abnormality is detected;
• and
• recording a second recovery process information indicating one or more start variables of the one or more recovery processes;
• wherein the controller is separated from the industrial machine and the controller is external of the industrial machine;
• and
• wherein the controller communicates with a plurality of industrial machines including the industrial machine via a network communication.

A non-transitory information storage medium having stored thereon a program for causing a computer to:

• detect an abnormality that has occurred in an industrial machine configured to execute each of a plurality of recovery processes and each of a plurality of production processes;
• detect a change of a plurality of start variables that correspond to the plurality of recovery processes, and
• start each of the plurality of recovery process when the industrial machine detects the change in the corresponding start variable,
• receive a specification of one or more recovery processes from a controller to be executed in order to perform recovery, based on a first recovery process information associating, for each of the plurality of recovery processes, at least a name of the each of the plurality of recovery processes with the start variable representing an operation of the industrial machine and indicating the change is to be performed by a recovery process program to be executed in the each of the plurality of recovery processes, when the abnormality is detected;
• and
• record a second recovery process information indicating one or more start variables of the received one or more recovery processes;
• wherein the controller is separated from the industrial machine and the controller is external of the industrial machine;
• and
• wherein the controller communicates with a plurality of industrial machines including the industrial machine via a network communication.
