Cross reference for operands used¶
The cross-reference of operands used is particularly valuable for more extensive system projects in order to obtain an overview of the operands used in the objects.
The following information is available through the cross reference:
- Use of operands in objects sorted by devices.
- Type of access to the operands: It is indicated whether values are read from the operands or written to the operands. The access mode "W" means "write", meaning that the operand is written to. The access mode "R" has the meaning "read" and signals a read access.
- Duplicate use of operands: If an operand is written to by different objects or in different properties, this usually indicates an error.
- The property in which the operand is used.
- The object type in which the operand is used.
- The object description of the object in which the operand is used.
Structure of the cross-reference of the operands used¶
The following image shows an example of the output of the cross reference of the operands used.
You can use the filter to reduce the output in the table to the search criteria specified in the filter. The characters specified in the filter are checked for occurrences in the device, operands, property, and object description. The respective operand is listed in the table for found locations.
Refreshing the cross reference (2)¶
Clicking on the button initiates the refreshing of the cross-reference.
Display "Not current" (3)¶
This display appears as soon as changes have been made in the system project that result in the cross reference no longer being current. You can now decide whether the cross reference should be refreshed by clicking on the "Refresh cross reference" button.
Export to CSV (4)¶
Clicking this button exports the contents of the table to a CSV file. The name and path of the CSV file can be selected in a dialog. Such a file can, for example, be opened or imported with Excel.
Operands of the device (5)¶
The name of the device to which the subsequent operands belong is specified before the list of operands.
Highlighting the object in which the operand is used¶
If you want to identify the object in which the operand is used, double-click on the line in the table. As a result, the drawing area is scrolled in such a way that the object is in the visible area. In addition, the object is given a marker that identifies the object.
The selection is retained until you selec t a new line by double-clicking it or until you click on the "Reset highlighting of objects" button in the action list.
