CODESYSとNode-RED間のデータ通信 その２

はじめに

CODESYSとNode-RED間でのデータ受け渡しについて、
こちらのCODESYS Network Variable List parserを使用する方法について記載します。
※以下の記事の続きです。

CODESYS側の設定（受信側）

Application
→オブジェクト変数の追加
→ネットワーク変数リスト（受信側）

ファイルからのインポートしか選択できなかったので、送信側を一旦作って保存したファイルを編集

以下のように作成したファイルをインポートしました。

UDPポート：1203
リストの識別子：2
パック変数：✓

NVL_Receive.gvl

<GVL>
  <Declarations><![CDATA[{attribute 'qualified_only'}
VAR_GLOBAL
	gInput:BOOL;
    gOutput:BOOL;
    gCounter:UINT;
END_VAR]]></Declarations>
  <NetvarSettings Protocol="UDP">

    <ProtocolSettings>
      <ProtocolSetting Name="Broadcast Adr." Value="255.255.255.255" />
      <ProtocolSetting Name="Port" Value="1203" />
    </ProtocolSettings>
  </NetvarSettings>
</GVL>

Node-RED側の設定（送信側）

送信用のノードを配置し、設定します。
設定が終わった後、デプロイを実行して動作するか確認します。
