Editor provides mechanism for automatic numbering of function blocks (Edit - Number function blocks menu item). This function allows you to quickly number blocks depending on their location on the diagram.
Two numbering algorithms are available:
Down then right
Column numbering from top to bottom, from left to right.
Right then down
Line numbering from left to right, from top to bottom.
Numbering mechanism focuses only on the visual arrangement of the diagram elements and does not adjust its work depending on the order of connecting the elements or their functionality.
Automatic numbering mechanism is designed for fast draft numbering.
After it, it is recommended to check the result and make manual adjustments.
