13.8.3 Working in the FBD and LD editor view
"Networks" are the basic entities in FBD and LD programming. Each network contains a
structure that displays a logical or an arithmetical expression, a POU (function,
program, function block call, etc.), a jump, a return instruction.
When creating a new object, the editor window automatically contains one empty
network.
Notice the general editor settings in the options dialog, category 'FBD, LD and IL'.
Tooltip containing information on variables or box parameters
The cursor being placed on the name of a variable or box parameter will prompt a
tooltip showing the respective type and in case of function block instances the
initialization value. For IEC operators SEL, LIMIT, MUX a short description on the inputs
will appear. If defined, also the address and the symbol comment will be shown as well
as the operand comment (in quotation marks in a second line).
