現場で思いついたラダー回路を、その場で描いて、メモごと残しておけます。 ■ 起動したら、まず回路の一覧 これまでに描いた回路が、名前とメモと日付で並びます。 「あのとき何を考えて組んだのか」を、開く前に思い出せます。 ■ 回路にメモを残せます 回路ぜんたいへのメモと、部品ひとつずつへのコメント。 どちらも後から検索できます。 ■ 探せます 回路の名前、メモ、部品のコメント、使ったデバイス名(X0 や Y10 など)から探せます。 ■ 描いて、その場で動かせます a接点・b接点・コイルを置いて、縦の線でつないで並列にできます。 入力を切り替えると、通電している線とONになったコイルがその場で分かります。 ■ 現場の外には持ち出しません 保存はすべて端末の中です。アカウント登録も、広告もありません。アプリ内課金のお支払いはお使いの端末とAppleの間で処理され、当方が内容に触れることはありません。 ■ 回路の保存数だけ買い切りで増やせます 描くこと、メモを残すこと、探すことは無料のまま全部使えます。保存できる回路の数だけに上限があり、上限をなくすアプリ内課金があります。月々の支払いは発生せず、上限に達しても、既にある回路の編集・保存はそのまま行えます。 [対応していないもの] タイマ・カウンタ、書き出し、クラウド同期には対応していません。 [ご注意] 本アプリは実機のPLCとは接続しません。画面上の動作は本アプリの論理モデルによる模擬です。 実際の設備の設計・運用の判断は、必ず実機と各メーカーの資料でご確認ください。
