When you download a Commander diagram or script to a motion
controller, the application program (generated from the Commander
diagram) is stored in both the application and the working memory,
erasing whatever program was previously stored there. Also, the initial
value of all user variables, initialized in the User Variables definition, is
stored directly in data memory. Finally, certain setup parameters are
stored directly in application and working memory. The setup parameter
values downloaded by Commander overwrite the values set in the
application menu.
The Online Toolbar’s Upload Options button (along with the Diagram
Menu’s Upload Options selection, and Ctrl + F9) let you upload
• The setup values from application memory (the power-up values).
• The cam tables and user variables directly from data memory.
• The application program from application memory.
