Technical Support Notes

Symptoms
Errors occur when Start button is pressed on OPU after project edit and build.

Cause
After the build process, the current group and points will not be correct in the robot controller.  When the project is run from the Run Window or Operator Window, the proper group object file and points are automatically loaded by SPEL for Windows.

 If the project is built, but not run from SPEL for Windows, then when a Start is attempted from the OPU, errors will occur because the proper group and points have not been loaded.

Remedies
Method 1

If your OPU is running in mode OPUNIT 0, you can press the Files button, then select the group you want to run.

If your OPU is not running in mode OPUNIT 0, then use one of the other methods described below.

Method 2

With this method, a macro is created to load the correct group object file and points after changing the project.

1. Create a macro with the following lines:

       dwnld "mygroup"
       dload "mygroup.pnt"

Substitute the group you want to use for "mygroup". 

2. Edit project.
3. Build project.
4. Open the macro by pressing F2 (or whatever key you used).
5. Run the macro by clicking Execute.
6. Switch to auto mode.
7. Press start on the OPU to start the program.

 Method 3

With this method, you must run the program one time from SPEL for Windows after changing the project and before using the OPU.

1. Edit project.
2. Build project.
3. Run the project one time from the Run Window.  This will load the group object file and points.
4. Switch to auto mode.
5. Press Start on OPU to start the program.
