PROBLEM TO BE SOLVED: To reflect necessary data update even when the data of a plurality of systems are stored in a memory for data storage.SOLUTION: A controller 4 comprises: a microcomputer part 5 having a CPU 8, the region of a memory 1 for comparison and the region of a memory 2 for temporary storage or the like; and a memory 3 for data storage different from the above mentioned memory. Update data generated in the microcomputer part 5 are stored in the memory 2 for temporary storage, and update data generated in the other equipment are stored in the memory 3 for data storage. When the update data are recorded in the memory 3 for data storage, the data of the memory 1 for comparison are compared with the data of the memory 2 for temporary storage or the data of the memory 3 for data storage to confirm the presence/absence of the data update, and when the data are updated, the update data of the memory 2 for temporary storage or the memory 3 for data storage are written in the memory 1 for comparison, and then the data of the memory 1 for comparison are written in the memory 2 for temporary storage and the memory 3 for data storage. |
