Summary:To provide an elevator system capable of changing a controller order to update a firmware according to an elevator operating state.SOLUTION: A master controller 30 provided in an elevator system 100 generates a transmission order of a firm image 31 to multiple sub-controllers 40 according to an operational state of an elevator 15, and transmits a packet 50 including the firm image 31 and the transmission order to the sub-controller 40 with a higher transmission priority. The sub-controller 40 with a higher transmission priority receives the packet 50 from the master controller 30 to update the firm image 31, and transmits the packet 50 to the sub-controller 40 with a next transmission priority.SELECTED DRAWING: Figure 3 【課題】エレベーターの運行状態に応じてファームウェアを更新するコントローラの順番を変更可能なエレベーターシステムを提供する。【解決手段】エレベーターシステム１００が備えるマスタコントローラ３０は、エレベーター１５の運行状態に応じて、複数のサブコントローラ４０に対するファームイメージ３１の送信順番を生成し、送信順番が優先されるサブコントローラ４０に対して、ファームイメージ３１及び送信順番を含むパケット５０を送信し、送信順番が優先されるサブコントローラ４０は、マスタコントローラ３０からパケット５０を受信してファームイメージ３１の更新を行い、送信順番が次に優先されるサブコントローラ４０にパケット５０を送信する。【選択図】図３
