1. A production system, comprising:
an industrial machine configured to execute each of a plurality of recovery processes and each of a plurality of production processes; and
circuitry;
wherein the industrial machine is configured to:
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,
wherein the circuitry is configured to:
detect an abnormality that has occurred in the industrial machine 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.
