FP_INTERRUPT_DISABLE

割り込みプログラム無効化

このFP命令は、割り込みタスクに割り当てられたすべてのプログラムの実行を無効にします。

解説

命令の実行中に割り込みプログラムが実行されている場合、割り込みプログラムは中断されます。
FP_INTERRUPT_CLEAR_REQUESTSを使用すると、割り込みが無効になっている間、ユニットによって一時停止された割り込み信号をクリアできます。
各ユニットの割り込みを無効または有効にするには、命令FP_INTERRUPT_ACTIVATEを使用します。

例

POUヘッダ

POUヘッダには、このプログラムで使用するすべての入力変数と出力変数を宣言します。 POUヘッダは全プログラム言語で使用できます。
