を備えることを特徴とするプログラマブルコントローラ。 - 前記文字コード管理部は、接続された外部機器から第2のエンコード方式を指定する旨のエンコード方式通知を受信したとき、前記第2のエンコード方式の使用を許可する使用許可通知を前記外部機器に送信し、前記使用許可通知を送信した後に制御ファイルの名称の転送を実行するとき、当該制御ファイルの名称のエンコード方式の変換を実行する、
ことを特徴とする請求項1に記載のプログラマブルコントローラ。 - 前記文字コード変換テーブルに対応付けが記述されているエンコード方式の一覧表をさらに備え、
前記文字コード管理部は、前記エンコード方式通知を受信したとき、前記一覧表を参照して前記第1のエンコード方式の文字コードと前記第2のエンコード方式の文字コードとが前記文字コード変換テーブルにより対応付けられているか否かを判定し、対応付けられていると判定した場合、前記使用許可通知を送信する、
ことを特徴とする請求項2に記載のプログラマブルコントローラ。 - 前記エンコード方式の一覧表は、エンコード方式の識別番号の一覧表であって、前記エンコード方式通知は、前記第2のエンコード方式の識別番号を含む、
ことを特徴とする請求項3に記載のプログラマブルコントローラ。 - 前記エンコード方式通知は前記外部機器との間の通信の生存確認信号を兼ねており、
前記文字コード管理部は、前記エンコード方式通知にエンコード方式の指定が含まれない場合、制御ファイルの名称の転送を実行するとき、当該制御ファイルの名称を前記第1のエンコード方式と予め決められたエンコード方式との間の変換を実行する、
ことを特徴とする請求項3または4に記載のプログラマブルコントローラ。
