Instance selection dialog box

Structure of the dialog box

The Instance selection dialog box consists of two or three tabs:

Variables

You can select an elementary variable or an element of a multi-element variable in this tab.
Function Blocks

You can select a formal parameter of a function block instance in this tab.
Interface

You can select a variable of a Program Unit in this tab.

NOTE: Program Units are only available for Modicon M580 and M340. Without Program Unit in the program structure the Interface tab is empty.

Variables tab

Elements of the Variables tab:

Element	Description
Text box	The selected variables are displayed in this text box.
Scope list	Allow to reduce the scope for the variable selection.
button	Clicking on this button updates the display corresponding to the filter term defined in the Name field.
button	Clicking on this button opens the Filtering data dialog box where you can define the conditions for the individual attributes.
Name	The name of the variable to search for can be entered in this text box. You can also use the joker * and ?.
button	Clicking on this button inverts the filter. The button changes from = to <> and vice versa.
Inside Structure	When you activate this check box, all structured variables are displayed.
Name	The names of the variables are displayed in this column.
Type	The types of the variables are displayed in this column.
Value	The initial value of the variables are displayed in this column.
Comment	The comments for the variables are displayed in this column.
Alias	The alias name of the IODDT, DDT, or Array element are displayed in this column.
Alias of	The complete paths of the variables when an alias name has been set are displayed in this column.
Address	The address in the controller are displayed in this column.
HMI Variable	This column displays if the variable is embedded in the data dictionary.
R/W Rights of Referenced Variable	This column displays the access rights when the variable is a Reference data type.
Effective Parameter	Only when the Instance selection dialog box is called from a section included in a Program Unit. This column displays the variable assignment for Program Unit parameters (input, output and input/output parameters).
Nature	Only when the Instance selection dialog box is called from a section included in a Program Unit. This column displays the nature of the Program Unit variables.

Function Blocks tab

Elements of the Function Blocks tab:

Element	Description
Text box	The selected function block instances are displayed in this text box.
button	Clicking on this button updates the display corresponding to the filter term defined in the Name field.
button	Clicking on this button opens the Filtering data dialog box where you can define the conditions for the individual attributes.
Name	The name of the function block instance to search for can be entered in this text box. You can also use the joker * and ?.
button	Clicking on this button inverts the filter. The button changes from = to <> and vice versa.
EFB	When you activate this checkbox, the instances of elementary function blocks (EFBs) are displayed.
DFB	When you activate this checkbox, the instances of derived function blocks (DFBs) are displayed.
Named by default	When you activate this check box, the function block instances are displayed whose default names (e.g. `FBI_19_3`, `TON_1`) have not been changed.
Name	This column displays the names of the function block instances and their formal parameters (inputs, outputs, public variables).
no.	This column displays the order number of the formal parameters in the function block.
Type	This column displays the types of the function block instances and the data types of their formal parameters (inputs, outputs, public variables).
Value	This column displays the initial value of the formal parameters.
Comment	This column displays comments about the function block instances and their formal parameters (inputs, outputs, public variables).
HMI Variable	This column displays if the formal parameter is embedded in the data dictionary.
R/W Rights of Referenced Variable	This column displays the access rights when the formal parameter is a Reference data type.

NOTE: Help for the Type..

Hold down the Alt+F1 keys and then click on the function block type for which you wish to access Help.

Interface Tab

Elements of the Interface tab:

Element	Description
Text box	The selected function block instances are displayed in this text box.
Scope list	Allow to select the data scope for the variable selection among the different Program Units.
Name	This column displays the names of the variables belonging to the Program Unit selected into the scope list. The variables are grouped by Nature (<inputs> , <outputs> , <inputs/outputs> , <public> , <external> ).
Type	This column displays the data types of the variables.
Value	This column displays the initial value of the variables.
Comment	This column displays the comment for the variables.
Effective Parameter	Only when the Instance selection dialog box is called from a section included in a Program Unit. This column displays the variable assignment for Program Unit parameters (input, output and input/output parameters).
Address	Only when the Instance selection dialog box is called from a section included in a Program Unit. The address in the controller are displayed in this column.
