'Edit' 'Input Assistant'
Shortcut:
This command provides a dialog box for choosing possible inputs at the current cursor position in the
editor window. In the left column choose the desired input category, select the desired entry in the
right column, and confirm your choice with OK. This inserts your choice at this position.
The categories offered depend upon the current cursor position in the editor window, i.e. upon that
which can be entered at this point (e.g. variables, operators, POUs, conversions, etc.).
If the option With arguments is active, then when the selected element is inserted, the arguments to
be transferred are specified with it, for example: function block fu1 selected, which defines the input
variable var_in: fu1(var_in:=);
Insertion of function func1, which uses var1 and var2 as transfer parameters: func1(var1,var2)
It is basically possible to switch between structured and unstructured display of the available
elements. This occurs through activation/deactivation of the Structured Display option.
Note:
For inserting identifiers you also can use the Intellisense functionality.
