Abstract
A control device includes a storage unit that stores a program, a program execution unit that executes the program stored in the storage unit to control a device to be controlled, and a backup execution unit that stores, at the start of a backup operation of the program currently being executed, the program, information for identifying a location currently in execution in the program, information for identifying a location currently being held in the program, and operation data, in a backup storage unit.
Claims5
A control device comprising:
- a memory configured to store a program containing information on steps and on transitions;
- and
- processing circuitry configured to:
- control a to-be-controlled device by executing the program stored in the memory;
- and
- in response to a backup event, perform a backup operation for the program currently being executed, including storing backup information that includes (a) the program, (b) executing step information for identifying a step being executed in the program at a start of the backup operation, (c) hold step information for identifying a step being held in the program at the start of the backup operation, and (d) corresponding operation data in a backup storage.

A control device comprising:
- a memory configured to store a program containing information on steps and on transitions;
- and
- processing circuitry configured to:
- control a to-be-controlled device by executing the program stored in the memory storage;
- and
- after completion of a backup operation performed by the control device for the program,
- obtain backup information stored as a result of the backup operation from a backup storage, the backup information including (a) the program, (b) executing step information for identifying a step being executed in the program at a start of the backup operation, (c) hold step information for identifying a step being held in the program at the start of the backup operation, and (d) corresponding operation data, and
- execute the program by restoring an execution state of the program as of a time of the start of the backup operation based on the obtained backup information.
