此样例程序仅是示例程序。用户需根据实际情况在此基础上进行修改,请勿直接使用该程序。

程序解读

以下为MM_S11_Viz_Timer样例程序的代码及相关解释说明。

与MM_S2_Viz_Basic样例相比,本样例仅新增了计时器的功能(加粗部分的代码)。因此,下文不再重复解释与MM_S2_Viz_Basic样例相同部分的代码(详情请参考MM_S2_Viz_Basic样例说明)。

上述样例程序代码对应的流程如下图所示。

sample11

下表为计时器的逻辑解读。

流程 代码及说明

通过循环计算每次从建立通信到完成抓取与放置所花费的时间

LOOP:
    ...
    GOTO LOOP;

上述代码表示,程序循环执行LOOP与GOTO LOOP之间的代码。

!reset timer to 0
ClkReset timer;

上述代码表示,将计时器timer重置为0。

!start timer
ClkStart timer;

上述代码表示,计时器timer开始计时。

!stop timer
ClkStop timer;

上述代码表示,计时器timer结束计时。

timer_val:=ClkRead(timer);

上述代码表示,通过ClkRead指令读取计时器timer计算的时间(即每次从建立通信到完成抓取与放置所花费的时间),然后将时间值赋值给timer_val变量。

TPWrite "single cycle time: "+numtostr(timer_val,3)+"s.";
  • numtostr(timer_val,3):将timer_val变量所表示的数值保留小数点后3位,然后转化为字符串。

  • TPWrite:在示教器屏幕上显示相应的字符串。

因此,整条语句表示,将计算的时间显示在示教器屏幕上。
