Example Program 5: MM_S5_Viz_SetBranch
Program Introduction
Description |
The robot triggers the Mech-Viz project to run, sets the exit port for the Branch by Msg Step in the Mech-Viz project, and then obtains the planned path for picking and placing. |
||
File path |
You can navigate to the installation directory of Mech-Vision and Mech-Viz and find the file by using the

Project |
Mech-Vision and Mech-Viz projects |

Program Description
This part describes the MM_S5_Viz_SetBranch example program.
| The only difference between the MM_S5_Viz_SetBranch example program and the MM_S2_Viz_Basic example program is that MM_S5_Viz_SetBranch can set the exit port of the Branch by Msg Step in the Mech-Viz project (this code of this feature is bolded). As such, only the feature of setting the exit port of the Branch by Msg Step is described in the following section. For information about the parts of MM_S5_Viz_SetBranch that are consistent with those of MM_S2_Viz_Basic, see Example Program 2: MM_S2_Viz_Basic. |
