FP_INTERRUPT_CLEAR_REQUESTS

清除一个单元的中断程序

该FP指令根据s_Control指定的数据来清除d_Slot指定的插槽中安装单元的中断程序。

参数

输入

d_Slot (WORD, INT, UINT)

插槽编号：1–16

s_Control (WORD)

用于清除指定插槽安装单元中断号的控制字：16#0–FF

(1) 较高的8位：固定为1
(2) 0：中断已清除
(3) 1：中断未清除

错误标志

sys_bIsOperationErrorHold（变为TRUE并保持为TRUE）: 如果使用索引寄存器指定的区域超出限制。
sys_bIsOperationErrorNonHold（对于一次扫描变为TRUE）: 如果使用索引寄存器指定的区域超出限制。

示例

全局变量

在全局变量列表中，定义项目中所有POU都可以访问的变量。

POU头

所有用于编程此函数的输入和输出变量已在POU头中声明。所有编程语言使用相同的POU头。
