样例程序15：MM_S15_Viz_GetDoList
程序解读
以下为MM_S15_Viz_GetDoList样例程序的代码及相关解释说明。
| 与MM_S2_Viz_Basic样例相比，本样例仅修改了如下加粗部分的代码。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）。 |

END上述样例程序代码对应的流程如下图所示。
下表是对加粗代码的逻辑解读。用户单击指令名称的超链接便可查看该指令的详细说明。
| 流程 | 代码及说明 | ||
|---|---|---|---|
获取规划路径 |
|
||
获取吸盘DO信号 |
|
||
转存规划路径 |
因此，“CALL JOB:MM_GET_PLANPOSE ARGF"1;71;61;31"”整条指令表示将第一个路径点的位姿、移动类型、末端工具编号、速度、视觉移动规划数据和自定义数据分别转存至指定变量。
|
||
移动到抓取点进行抓取 |
因此，上述语句表示，机器人在移动到抓取点（P072）后，通过MM_SET_DOLIST指令设置吸盘DO信号，从而完成抓取。 |
