#54 4ch非絶縁ドライ接点入力
Tibbitの配置
Tibbit #54を挿入します。
ノードの配置
リレーの制御のために、functionノードを使用します。
以下のようにフローを配置します。
functionノードの編集を開き、コードに以下を記述します。
値を取得したいラインを指定します。
|
1 2 |
msg.payload = [{line: 'A'}]; return msg; |
ラインを複数取りたい場合は、以下のように指定ができます。
|
1 2 |
msg.payload = [{line: 'A'},{line: 'B'},{line: 'C'},{line: 'D'}]; return msg; |
ノードの設定を開き、スロットを選択します。
Node-REDデプロイ後、injectノードをクリックすると値を取得ですることができます。
Outputsは指定したライン分、配列で取得できます。

Edgeの取得
INのEdgeを取得したい場合は、inノードを使用し以下のようにフローを配置します。
OutputsはラインとHIGH/LOWが出力されます。
