#05 RS485トランシーバ
Tibbitの配置
Tibbit #05を挿入します。
使用できるスロットは、1,3,5,7,9です。
シリアルの設定
シリアル設定の登録方法は、#01 RS232トランシーバのチュートリアルの「シリアルの設定」を参考にしてください。
ノードの配置
送受信切り替え
このTibbitブロックでは、まず送受信の切り替えを行う必要があります。
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。
|
1 2 |
msg.payload = {act: 'io', v: 1}; return msg; |
|
1 2 |
msg.payload = {act: 'io', v: 0}; return msg; |
ノードの設定を開き、スロットとシリアル設定を選択します。
Node-REDデプロイ後、各injectノードをクリックするとOutput/Inputを切り替えることができます。

シリアルのIN
以下のようにフローを配置します。
ノードの設定を開き、スロットとシリアル設定を選択します。
Node-REDデプロイ後、機器からのデータを受信します。
シリアル設定でのハードウェアフローは使用できません。

シリアルのOUT
送信するデータをセットするため、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。
「test」の部分が送信されるデータになりますので、適宜変更してください。
→文字列以外にもbytesなどでも可能。

1 2 |
msg.payload = Buffer.from("test\n"); return msg; |
ノードの設定を開き、スロットとシリアル設定とモードを選択します。
Node-REDデプロイ後、injectノードをクリックすると機器へデータを送信することができます。
シリアル設定でのハードウェアフローは使用できません。
