Viewing LD diagrams

The diagram is entered in a logical grid. All objects are snapped to the grid. You can use the commands of the “View” menu for displaying of hiding grid lines. The (x,y) coordinates of the mouse cursor are displayed in the status bar. This helps you locating errors detected by the compiler, or aligning objects in the diagram.

At any moment you can use the commands of the “View” menu for zooming in or out the edited diagram. You also can press the [+] and [-] keys of the numerical keypad for zooming the diagram in or out.

You also can drag the separation lines in vertical and horizontal rulers to freely resize the cells of the grid:

The LD editor adjust the size of the font according to the zoom ratio so that the name of variables associated with contacts and coils are always visible. If cells have sufficient height, variable names are completed with other pieces of information about the variable:
- its tag (short description)
- its description text
- its I/O name (%...) if the variable has a user defined name.
