The default value of this option for a new application is "unchecked". After changing this setting a Rebuild All Project of the application is necessary, because it influences the generated code. For detailed information, refer to Maintain Output Links on Disabled EF. NOTE: This setting allows keeping the same behavior as a Concept application.

FBD

This area is used to define the number of rows and columns for Function Block Diagrams (FBD).

Element	Description
Number of rows	From 240 to 1440 (steps of 10).
	Modification:	Offline only
	Action required:	No build necessary
Number of columns	From 60 to 360 (steps of 10). The section area (number of rows x number of columns) cannot exceed the maximum size of 86,400 grids: for example, 240 x 360 or 1,440 x 60. The two input fields are impacting one another. For example, the number of rows is determined by the internal calculation 86,400/number of columns (limited to the lower tenth).
	Modification:	Offline only
	Action required:	No build necessary

LD

Element	Description
Right-justify coils	If this check box is selected, coils are automatically placed on the right power rail.
	Modification:	Offline only
	Action required:	No build necessary
Number of columns	Define the number of columns in an `LD` section in this box. From 11 to 63. Note: These settings are only valid for new `LD` sections and not for existing sections.
	Modification:	Offline only
	Action required:	No build necessary
Single scan edge detection for EBOOL	When an `EBOOL` is written only one time (through OFS, HMI, by program or forced by Control Expert): If this check box is selected, writing or forcing an `EBOOL` activates the edge detection for one cycle. If this check box is not selected, writing or forcing an `EBOOL` activates the edge detection until the next writing of this `EBOOL`.
	Modification:	Offline only
	Action required:	Rebuild All Project (Offline)

LD > Mixed display

SFC > multi token

The SFC multi token option is for PL7 migration and to support the GRAFCET specification that used to be supported by Telemecanique.

Element	Description
Max. # of active steps/section	This box is only available if the Allow multiple token check box activated. The maximum number of active steps per section can be defined (including all their macro sections) in this box. From 1 to 100.

SetSteps: keep previous step(s) in active state	This box is only available if the Allow multiple token check box activated. When this check box is selected, all currently active steps remain active when you set new steps (Animation Panel or function block). When this check box is not selected, all currently active steps are deactivated when you set new steps (Animation Panel or function block).

Parallel branches: allow jump in/out	This box is only available if the Allow multiple token check box activated. When this check box is selected, jumps can be made into or out of a parallel sequence, see Jump into a parallel sequence and Jump out of a parallel sequence.
	Modification:	Online possible
	Action required:	Build Changes (Offline)
Allow multiple evolutions by divergence of sequence selection	This box is only available if the Allow multiple token check box activated. When this check box is checked, all transitions of an alternative branch are processed in parallel (x-out-n-select), see x-out-n-select. When this check box is not checked, all transitions of an alternative branch are processed in sequence (1-out-n-select), see Alternative sequences.

	Action required:	Build Changes (Offline)

NOTE: Verify that you optimize the number of active steps and active actions at the right number to get the project to fit into the available memory.

LL984

Element	Description
SKP enabled	This LL984 setting is enabled only, if the LL984 library setup was installed. When this check box is selected, the L9_SKP function block can be used in your project. NOTE: Modifying this setting leads to a reanalysis of the LL984 networks. This is also possible in online mode.

Description

SKP enabled

This LL984 setting is enabled only, if the LL984 library setup was installed.

When this check box is selected, the L9_SKP function block can be used in your project.

NOTE: Modifying this setting leads to a reanalysis of the LL984 networks. This is also possible in online mode.

LL984 > Network Display

Element	Description
Printing View	Using this list you select view1 to view4 defined under items View 1 to View 4 (see below). The default view is view4. The view you select for the Printing View setting is used for printing the LL984 networks.
	Modification:	Online possible
	Action required:	No build necessary
Column Width	Using this field you can enter the column width as a floating point value ( 1.0 to 3.0. For example, a value of 3.0 means a 3 times larger column width. The default width is 1.0. NOTE: Modifying the Column Width setting does not lead to the need of a new Build.
	Modification:	Online possible
	Action required:	No build necessary
View 1 to View 4	The LL984 editor can display various information concerning variables attached to coils, contacts, and function block nodes. According to the settings for View 1 to View 4 the LL984 editor shows the following information: Address (for example, %M100) 984-address (for example, 400100 Variable name Variable comment Descriptors 1 to 9 Topological address For further information, refer to Items of the View 1 to View 4 Settings.
