A new LD block with a default name is created.
Note: If you use a template or add a target, the first block added to a target is
named “_MAIN” and subsequent blocks added are named LDBK1, LDBK2, and so
on, by default.
2. Rename the block as desired.
To open an LD block for editing
• In the Project tab of the Navigator, double-click an LD block.

LD block, click the tab that displays its name at the bottom of the editor window.
