An industrial machine management system comprising an industrial machine and a management device, characterized by the industrial machine being a robot controller that controls a robot and the management device comprising: a collector configured to collect changeable setting data of the industrial machine as a backup, the setting data being a robot control program that causes the robot controller to control the robot; a backup determiner configured to determine whether a change has been made to the setting data by comparing the setting data collected as the backup at a first time point with the setting data collected at a second time point different from the first time point, the change being an addition, a change, or a deletion of a predetermined command in the setting data, the predetermined command being a command that affects a track of the robot; a storage configured to store the setting data collected as the backup at the first time point and state information based on a motion state of the robot detected by a sensor; a pre-change obtainer configured to obtain, as pre-change information, the stored state information regarding a pre-change state of the industrial machine as of time prior to the change made to the setting data; a post-change obtainer configured to obtain, as post-change information the stored state information regarding a post-change state of the industrial machine as of time after the change made to the setting data; and an outputter configured to, based on the pre-change information and the post-change information, output influence information regarding an influence of the change. the industrial machine being a robot controller that controls a robot and the management device comprising: a collector configured to collect changeable setting data of the industrial machine as a backup, the setting data being a robot control program that causes the robot controller to control the robot; a backup determiner configured to determine whether a change has been made to the setting data by comparing the setting data collected as the backup at a first time point with the setting data collected at a second time point different from the first time point, the change being an addition, a change, or a deletion of a predetermined command in the setting data, the predetermined command being a command that affects a track of the robot; a storage configured to store the setting data collected as the backup at the first time point and state information based on a motion state of the robot detected by a sensor; a pre-change obtainer configured to obtain, as pre-change information, the stored state information regarding a pre-change state of the industrial machine as of time prior to the change made to the setting data; a post-change obtainer configured to obtain, as post-change information the stored state information regarding a post-change state of the industrial machine as of time after the change made to the setting data; and an outputter configured to, based on the pre-change information and the post-change information, output influence information regarding an influence of the change. a collector configured to collect changeable setting data of the industrial machine as a backup, the setting data being a robot control program that causes the robot controller to control the robot; a backup determiner configured to determine whether a change has been made to the setting data by comparing the setting data collected as the backup at a first time point with the setting data collected at a second time point different from the first time point, the change being an addition, a change, or a deletion of a predetermined command in the setting data, the predetermined command being a command that affects a track of the robot; a storage configured to store the setting data collected as the backup at the first time point and state information based on a motion state of the robot detected by a sensor; a pre-change obtainer configured to obtain, as pre-change information, the stored state information regarding a pre-change state of the industrial machine as of time prior to the change made to the setting data; a post-change obtainer configured to obtain, as post-change information the stored state information regarding a post-change state of the industrial machine as of time after the change made to the setting data; and an outputter configured to, based on the pre-change information and the post-change information, output influence information regarding an influence of the change.
