中断驱动块

3种类型的中断用于启动程序块:

■由CPU产生，中断的时间间隔由用户指定。如果设定了初始延时，则在完成停止运行转并经过初始延时时间后，开始计算中断时间。

■I/0中断由/0模块发出，/0中断用于指示离散输入状态的改变(上升沿/下降沿)，模拟量范围限制(高/低报警)和高速计数器事件。

■模块中断由VME模块产生。每个模块支持单个中断。

中断处理

只要程序块除了OK输出外没有其他的参数，I/O、 模块或者定时中断可以用于_ MAIN 块外的任何程序块。在中断和程序块关联后，每次中断触发后，都会执行这个程序块。一个模块可以和多个定时中断、/0 中断以及模块中断相关联。关于程序块中断的优先级。

如果参数化程序块和外部程序块被中断触发，他将%P数据作为本地数据%L继承。例如，参数化程序块和外部程序块内的本地变量%L00005继承的是变量%P00005。

注意:作为中断结果运行的程序块内有定时器函数块时，这个定时器块的时间不累加。中断触发的程序块可以调用其他的程序块。中断驱动执行时的应用程序堆栈不同于正常的模块化程序执行时的堆栈。特别的，嵌套调用限制不同于从_ _MAIN 块调用的情况。如果一个调用导致堆栈空间不足，无法完成调用，CPU 会记录为“堆栈溢出故障”。

I/0中断

程序块可以由某些硬件输入的中断信号触发。例如，24 VDC，32 回路的输入模块(IC697MDL650)，不管输入信号是上升沿还是下降沿，第一.次输入时都发出一个中断。如果模块配置中将中断功能使能，则中断可以触发执行一个程序块。

I/O中断在程序块属性栏中配置，触发必须使用全局变量%l, %AI或者%AQ。

模块中断

如果在模块硬件配置中将VME中断参数使能，程序块可以由VME模块输入的中断信号触发。PAC系统CPU允许每个模块有-一个中断。

要配置模块中断，在程序块属性栏中标明模块所在的机架/槽号/中断ID即可。
