FBD, LD, and IL Editor

Overview

The Tools > Options > FBD, LD and IL Editor dialog box allows settings concerning the editing in the FBD and LD editor.

General Tab

View
Show network title	The network title - if defined - is displayed in the upper left corner of a network.
Show network comment	The network comment - if defined - is displayed in the upper left corner line of a network. If the network title is visible, the comment will display in the line below the title, too.
Show box icon	If a function block or a function available via a library or via the object properties is provided with an icon (bitmap), this icon will be displayed in the box in the FBD and LD editor. Also the standard operators are provided with icons.
Show operand comment	The comment which can be assigned to an operand in the implementation part of the editor is displayed. The operand comment only refers to the usage of the operand in place, in contrast to the symbol comment, which is defined at the declaration of a variable. Operand comments can be edited in the editor. This comment is truncated automatically depending on available space. To limit the comment to a defined width, activate the option Fixed size for operand fields and set the parameters of the dialog box Operand Sizes according to your individual requirements.
Show symbol comment	For each variable which has got a comment in its declaration, this comment will be displayed above the identifier of the symbol.
Show symbol address	For each symbol (variable) the assigned address will be displayed above the identifier of the symbol.
Show network separators	A separator line is displayed between the individual networks.
Behavior
Placeholder for new operands	Not implemented yet.
Empty operands for function block pins	If this option is activated, the operand field for the pins of new function blocks will be left empty (instead of ???).
Fixed size for operand fields: The editor of FBD, LD, and IL adjust the size of the operand fields automatically. With this option, you can adjust the length and the height of the operand fields to a specific size.
Operand width, characters	This value defines the width of the operand field (number of characters).
Operand height, lines	This value defines the height of the operand field (number of lines).
Operand comment height, lines	This value defines the height of the operand comment field (number of lines).
Symbol comment height, lines	This value defines the height of the symbol comment field (number of lines).

FBD Tab

View
Network with linebreaks	If this option is activated, the line of the connections of a network will be broken in a way where as many elements as possible are visible in the current editor window width. This can affect which networks are enlarged in height. If the editor window is too small, networks will not be broken.
Connect boxes with straight lines	If this option is activated, the network components will be arranged in a way where the lines in between are of a fixed, short length, thus reducing the horizontal space required for displaying the networks. This can affect that boxes are enlarged in height, for example, to provide enough space for input and output elements. If the option is not activated, the elements will keep their standard size and the connection lines adapt to the need of space.
Behavior
Default network content	This option defines which content is displayed in the editor when you insert a new network. (Empty, Assignment, and Empty box)
After insertion select	This option defines which element is selected after a new network has been inserted (Element, Network)

LD Tab

View
Network with linebreaks	If this option is activated, the line of the connections in a network will be broken in a way whereas many elements as possible are visible in the current editor window width. This can affect which networks are enlarged in height. If the editor window is too small, networks will not be broken.
Behavior
Default network content	This option defines which content is displayed in the editor when a new network is inserted. (Empty, Contact on coil, and Empty box)
After insertion select	This option defines which element is selected after a new network has been inserted (Element, Network).

IL Tab

View
Enable IL	Enable this option to make the IL implementation language available in EcoStruxure Machine Expert.
Behavior
Default network content	This option defines which content is displayed in the editor when a new network is inserted. (Empty, LD and ST, CAL)
After insertion select	This option defines which element is selected after a new network has been inserted (Text, Network)

Print Tab

Layout options
Fit method	Select an option from the list for resizing.
Avoid cutting of elements	Activate this option to print elements that do not fit on one page, on the next page.
Mark connections on adjacent pages	This option is only available if the option Avoid cutting of elements is activated. Activate this option to print small markers on adjacent pages.
