Do one of the following:

• On the main toolbar, press

• In the Project menu, choose Offline.

When switching a program back to online mode, the DPL editor will request whether the program should be built if it has not been built since it was edited. If the program is different to the one on the target the DPL editor will offer to download the modified program.
