FP_INTERRUPT_ACTIVATE

控制一个单元的中断程序的激活

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

参数

输入

d_Slot (WORD, INT, UINT)

插槽编号：1–16

s_Control (WORD)

用于激活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0
(2) 0：中断禁用
(3) 1：中断使能

标注

应该为给定的中断号执行的中断程序（INTPG 0-7）可以分配给具有适当编号的中断任务。
可以使用插槽编号计算中断号，如下所示：<插槽编号> * 10 + INTPG。

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。

	VAR
		bEnable_Interrupt: BOOL:=FALSE;
		bComparisonMatchMonitor: BOOL:=FALSE;
		bDisableHscUnit: BOOL:=FALSE;
		bDisable_Interrupt: BOOL:=FALSE;
