Abstract
An industrial machine management system includes circuitry that collects changeable setting data of an industrial machine, determines, based on the setting data at each time point of multiple time points, whether a change has been made to the setting data, obtains change information regarding the change when the change is determined as having been made to the setting data, determines whether a predetermined event has occurred in the industrial machine, identifies, when the predetermined event is determined as having occurred, the change information such that the change information is related to the predetermined event, and outputs the change information that is identified.
Claims20
An industrial machine management system, comprising:
- a management device including a data storage and circuitry;
- and
- a first industrial machine that stores a changeable program including program codes, wherein
- the program codes include a movement code that indicates a position of a second industrial machine,
- the first industrial machine executes the program and controls a physical movement of the second industrial machine,
- the circuitry is configured to:
- collect a changeable program of an industrial machine as a backup, and
- determine whether the movement code has been changed, by comparing the program collected as the backup at a first time point with the program collected at a second time point different from the first time point,
- the data storage is configured to store the program collected as the backup at the first time point and change-unchanged information regarding whether the movement code has been changed, and
- the circuitry is configured to:
- obtain change information regarding a change of the movement code based on the change-unchanged information and the program collected as the backup at the first time point,
- determine whether a predetermined event has occurred in the first industrial machine,
- identify, when the predetermined event is determined as having occurred, the change information such that the change information is related to the predetermined event, and
- output the change information that is identified.
A method for an industrial machine system that includes a first industrial machine that stores a changeable program including program codes, the program codes including a movement code that indicates a position of a second industrial machine, the first industrial machine executing the program and controlling a physical movement of the second industrial machine, the method comprising:
- collecting a changeable program of an industrial machine as a backup:
- determining whether the movement code has been changed, by comparing the program collected as the backup at a first time point with the program collected at a second time point different from the first time point;
- storing the program collected as the backup at the first time point and change-unchanged information regarding whether the movement code has been changed;
- obtaining change information regarding a change of the movement code based on the change-unchanged information and the program collected as the backup at the first time point;
- determining whether a predetermined event has occurred in the first industrial machine;
- identifying, when the predetermined event is determined as having occurred, the change information such that the change information is related to the predetermined event;
- and
- outputting the change information that is identified.
A non-transitory computer-readable storage medium storing a program for causing a system, which includes a first industrial machine that stores a changeable program including program codes, the program codes including a movement code that indicates a position of a second industrial machine, the first industrial machine executing the program and controlling a physical movement of the second industrial machine, to execute a method, the method comprising:
- collecting a changeable program of an industrial machine as a backup;
- determining whether the movement code has been changed, by comparing the program collected as the backup at a first time point with the program collected at a second time point different from the first time point,
- storing the program collected as the backup at the first time point and change-unchanged information regarding whether the movement code has been changed;
- obtaining change information regarding a change of the movement code based on the change-unchanged information and the program collected as the backup at the first time point;
- determining whether a predetermined event has occurred in the first industrial machine;
- identifying, when the predetermined event is determined as having occurred, the change information such that the change information is related to the predetermined event;
- and
- outputting the change information that is identified.
