Find all Logic References to a Tag

The

 window helps locate where the logic references tags and memory. View the hierarchy of aliases that may refer to a memory location or base tag. To access the
Cross Referenc
e window, from the
Search
menu, choose
Cross Reference
. The
Cross Reference
 window appears, displaying the
By Logic
tab.
To find all Logic References to a Tag:
  1. For the
    Type
    field, choose
    Tag
    .
  2. Choose the scope of the tag to Cross Reference.
  3. Choose the tag name to Cross Reference.
    Enter a specific tag name or choose one from the list.
    A list of logic references to the specified tag displays in tabular format. The list contains an entry for each reference to the specified tag, in every instruction, of every rung, of every routine in the project file. Also included in the list are references from SFC, FBD, and ST.
  4. From the
    Show
    field, select the filter to limit the type of tags that appear.
    Choose from:
    • Show All - display all cross references for the selected tag (default)
    • Destructive - display only destructive references for the selected tag
    • Non-destructive - display only non-destructive references for the selected tag

      TIP:
      This filter only works for tags in the By Logic view; any other view disables this selection.
Only one filter is in effect at one time.
TIP:
Search multiple tags by typing in the first few letters of a tag and the wildcard character
*
 at the end. For example, type the letters
in*
 to display cross reference information for all tags beginning with letters
in
.
