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.

(canceled)
A control device comprising:
- a storage unit to store a program containing information on steps and on transitions;
- a program execution unit to execute the program stored in the storage unit and to control a device to be controlled;
- and
- a backup execution unit to store, at a start of a backup operation of the program currently being executed, the information on steps and on transitions contained in the program, executing step information for identifying a step currently being executed in the program, hold step information for identifying a step being held in the program, and operation data, in a backup storage unit.

A control device comprising:
- a storage unit to store a program containing information on steps and on transitions;
- a program execution unit to execute the program stored in the storage unit and to control a device to be controlled;
- and
- a restore execution unit
- to obtain, after completion of a backup operation of the program currently being executed, information on steps and on transitions contained in the program, executing step information for identifying a step currently being executed in the program, hold step information for identifying a step being held in the program, and operation data, from a backup storage unit that has stored, since a start of the backup operation, the information on steps and on transitions contained in the program, the executing step information, the hold step information, and the operation data, and
- to restore an execution state of the program as of a time of start of the backup operation based on the information obtained,
- wherein the program execution unit executes the program with the execution state of the program as of the time of start of the backup operation as restored by the restore execution unit.
