Symbol Configuration Editor

The View button allows you to set the following filters to reduce the number of displayed variables:

Even variables not yet added to the symbol configuration, but available for this purpose in the project, are displayed.

Also variables from libraries, not yet added to the symbol configuration, but available for this purpose in the project, are displayed.

This setting is effective only when the unconfigured variables are displayed (see the two filters described above).

It has the effect that also those variables are listed, which are already selected for getting symbols by {attribute 'symbol' := 'read'} within their declaration. Such symbols are displayed grayed. The Attribute column shows which access right is set for the variable by the pragma. Refer to the following description of the Access Rights column.

The Build button allows you to build the project. The build run refreshes the variables view in the configuration editor.

The Settings button allows you to activate the following options:

This function is not supported.

This has the effect that comments assigned to variables are also exported to the symbol file.

This has the effect that the flags that contain the namespace are also exported to the symbol file. They provide additional information on the origin of the node in the namespace when OPC UA is active.

Opens the Comments and Attributes dialog box that allows you to configure the contents of the symbol configuration and the XML file.

Opens the Options tab of the Properties dialog box of the selected controller. Refer to the description of the Access variables in sync with IEC tasks option in the EcoStruxure Machine Expert Menu Commands Online Help.

For further information, refer to the paragraph Additional Information on the Option Configure synchronisation with IEC tasks....

Select this option to calculate the data output in the same way as in SoMachine / SoMachine Motion versions prior to V4.3.

Do not use this layout together with exported STRUCTs that use the attributes pack_mode or relative_offset.

The data layout created for the client is adapted as far as possible to the layout created by the compiler.

Select this option to calculate the data output in an optimized form, independent of the internal compiler layout.

The optimization impacts only variables of a structured type and function blocks. No gaps with padding bytes are generated for members that are not published, for example, because they are deactivated in the Symbol Configuration. For internal members, for example, function blocks implementing interfaces, no gaps are created either.

This option is by default selected for projects created with SoMachine / SoMachine Motion versions V4.3 or later, or with EcoStruxure Machine Expert. The setting is preserved after a Project update.

This option requires SoMachine / SoMachine Motion versions V4.3 or later, or EcoStruxure Machine Expert. It is the default setting when creating a new Symbol Configuration.

By default, this option is not selected, as EcoStruxure Machine Expert V2.0 and later versions are delivered with an OPC server V3.5 and later.

Select this option for the exchange of variables with an OPC server V2.0 to achieve the following behavior:

• Program variables are exported without an application name (Application.PLC_PRG.MyVar –> PLC_PRG.MyVar).

• Global variables are additionally exported without the GVL name (Application.GVL.MyGlobVar –> .MyGlobVar).

This option is only available if the function is supported by the controller. Consult the Programming Guide specific to your controller for further information.

If the option is selected, the action Execute can be set in the symbol table for symbols of POUs of type function, function block, method, or program.

As a prerequisite, the Support OPC UA features option must be selected.

This option is available if the option Support Calls of Functions, FBs, Methods and Programs is supported by the controller.

Select this option to export information about called functions, function blocks, methods, or programs to the symbol file.

Select this option to display a toolbar above the Symbol configuration table. Also refer to the Toolbar for Symbol Set Configuration paragraph.

Opens the dialog box for saving a file in the file system. Allows you to create an XSD (XML Schema Definition) format of the symbol file, for use in external programs.

The column shows a list of POUs. You can select variables to be exported. If you select variables of a structured data type, all members of the structure will be exported.

You may also select only particular member variables in the dialog box Symbol Configuration for Data Type. Click the browse ... button in the Members column to open this dialog box. For further information, refer to the description of the Members column.

To modify the access rights for a selected item, click the Access Rights column.

Each mouse-click switches the symbol within the following definitions:

• : read and write

• : write-only

• : read-only

• none

Shows the maximum access rights.

An icon is displayed if the access right was assigned by attribute.

Shows the data type of the variable.

Variables of an alias data type are displayed as shown in the following example of a variable:

myVar : MY_INT,, where MY_INT is an alias declared as: TYPE MY_INT : INT; END_TYPE.

In this case, the Type column shows MY_INT : INT.

Click the ... button in the Members column to open the Symbol Configuration for Data Type dialog box. It allows you to select only particular member variables. In case of nested types, this dialog box again provides a button to open another Symbol Configuration for Data Type dialog box.

This selection applies to all instances of this data type for which symbols are exported. If not all members of a structured type are exported, then an asterisk (*) is displayed in the check boxes of the members to indicate that all exportable members of that type are exported.

Shows any comments which have been added in the declaration of the variable.

The list contains already defined symbol sets.

Opens the Add a New Symbol Set dialog box for specifying a name for this set.

Opens the Add a Duplicate from Selected Symbol Set dialog box. It allows you to create a copy of the set selected in the list. You can adapt the default name (<group name>_duplicate) to your individual requirements.

Opens the Rename the Selected New Symbol Set dialog box for specifying another name for the set selected in the list.

Opens a dialog box prompting whether the set selected in the list should be deleted.

Opens the Symbol Rights view of the device editor.

Symbol table contents

This function is not supported.

Include comments

Include attributes

Also include comments and attributes for type nodes

XML symbol file contents

Namespace node flags provide additional information about the origin of a node in the namespace. Node flags are available in the symbol table when OPC UA is activated.

Deselect this option to prevent namespace node flags from being inserted in the XML file if your parser cannot process them.

Select this option to save comments in the XML file.

In SoMachine / SoMachine Motion versions prior to V4.4, this includes the setting Prefer docu comments.

Select this option to save attributes in the XML file.

This option is only available if the option Include comments or the option Include attributes is activated.

If this option is selected, the information for type nodes is also included (user-defined types, such as STRUCT and ENUM elements).

If this option is not selected, comments and attributes are only available for directly exported variables.

Select comments

These parameters are only available if one of the Include comments options is activated.

Select the options to determine the kind of comments that are saved in the symbol configuration.

Include normal comments:

(*IEC/ Pascal style comments *) // C++-Style comments with double-slash

Always include both types of comments

Prefer docu comments, fallback to normal ones

Prefer normal comments, fallback to docu comments

Filter Attributes (case insensitive)

These parameters are only available if one of the Include attributes options is activated.

Select the options to determine the attributes that are saved in the symbol configuration.

Match simple identifiers (“foo”, “bar”)

Include attributes starting with:

Filter Attributes with regular expression
