Reference Information by Logic
Use the
By Logic
tab on the Cross Reference
dialog box to navigate to specific logic by double-clicking a row. Navigate to a language editor, the Tag Editor, or the Data Monitor by right clicking on the selected element. Sort each column by clicking on the column header.Columns on the By Logic tab:
Column | Description |
|---|---|
Element | Displays the mnemonic of the referencing instruction. For structured text, this column displays the text line referencing the selected tag. Place the cursor over the structured text element to display a tooltip that shows the text line that references the tag. |
Container | The name of the program (or Phase) or Add-On-Instruction that contains the routine or logic reference. Icons indicate container types. |
Routine | The name of the referencing routine. |
Location | The location of the reference within the routine. The number in parentheses indicates the number of references that exist for the specified tag. When a routine is locked, this column displays Source not available . |
Reference | The actual reference, which is a tag name with an optional component specified. |
BaseTag | The name of the base tag for alias references. |
Destructive | Displays a Y for a destructive reference and an N for a non-destructive reference.A reference is said to be destructive if the execution of the instruction can change the data value of the tag (that is, if the tag is written by the instruction). A reference is non-destructive if the instruction only uses or reads the value and cannot modify it. Tip: For structured text or sequential function chart routines, this column sometimes displays Not Verified . This means that the structured text in that routine is not verified, and the cross reference is not yet complete. Also, if the routine has errors, the cross reference information is not updated; for accurate cross reference information, correct any errors in the routine, verify the routine, and then refresh the cross reference view. |
Description | The associated operand comment for the tag (if it exists), including pass-through. The Base Tag description is used if you have checked the Show Pass-Through Properties on the Project tab in the Controller Properties dialog box.When showing an internal cross reference to Add-On-Instructions Parameters or Local Tags, if the pass-through feature is turned on, descriptions are passed-through the same as they are for the Parameters and Local Tags in the Instruction Definition editor. |
