PROBLEM TO BE SOLVED: To provide a program rewriting system capable of easily restoring, when the program of a controller is rewritten and a problem occurs in the rewritten program, the program before rewriting.SOLUTION: In rewriting the program of a motor controller 101, the program is divided and the divided programs are transmitted to another controller for storage by a divided program transmission unit 116 of the motor controller 101; and after that, the program is rewritten by a rewriting program transmitted from a tester 103; and when an abnormality of the operation by a new program thus obtained is detected by a state detection unit 115, the divided programs are transmitted from the other controller and the original program is written back.SELECTED DRAWING: Figure 1

    【課題】制御装置のプログラムを書き換え、この書き換えたプログラムに問題があった場合に、簡単に書き換え前のプロラムに戻すことができるプログラム書き換えシステムを得る。【解決手段】モータ制御装置101のプログラムを書き換える場合、モータ制御装置101の分割プログラム送信部116により、プログラムを分割して、各分割プログラムを他の制御装置に送信して保存させ、そののちに、テスタ103から送信される書き換えプログラムにより、プログラムを書き換え、この新しいプログラムによる動作の異常を状態検出部115により検出した場合には、他の制御装置から分割プログラムを送信させて、元のプログラムに書き戻すようにした。【選択図】図1
