Claims (1)
周期毎に対応する入力データ領域の内容を更新し
、それに基づいた制御等を行なうシーケンサ装置
において、同一周期内に同一入力情報が２度変化
した場合、その直後に起動する周期処理で１回目
の変化データのみを入力データ領域に格納し、２
回目の変化データは別領域に一旦セーブして次の
周期処理で入力データ領域に格納することにより
入力情報がもれないようにしたことを特徴とする
シーケンサ装置。 In a sequencer device that reads input information such as on/off of contacts, updates the contents of the corresponding input data area at regular intervals, and performs control based on this, if the same input information changes twice within the same cycle, In the periodic process that starts immediately after that, only the first change data is stored in the input data area, and the second change data is stored in the input data area.
1. A sequencer device characterized in that data of a change in the first cycle is temporarily saved in a separate area and stored in an input data area in the next periodic processing, thereby preventing input information from being leaked.
