Searching and Cross Reference
General
The searching function may be accessed a number of ways:
1) From the search menu
2) Using the quick search tool
3) Using the Ctrl-F shortcut
Searching has many options that can be configured. It is possible to have the
item visible on the screen and have the search function report the item not
found. The search results are shown in the results window.
If you double click on the result, the software will open the routine / rung listed.

Searching and Cross Reference
The search function is accessed from the search menu or using Ctrl-F.
Conventional searching can be tailored to meet the users’ needs. Some of the
variations include:
• Find What – Tag names, instruction types or descriptors
• Find Within – Current Routine, All Routines in current program, all
routines in current task or all Routines
• Search Direction – Up or Down from the cursor
• Wrap – When searching from the center of a routine, if the wrap is on
the software will search to the end of the specified routine and wrap
back to the top of the routine.
The degree and extent to which searching can be customized depends on the
software revision of RSLogix 5000. Refer to RSLogix 5000 release notes for
further information.

Search and Replace
The Search and Replace function is an advanced feature that should be used
with care. It is possible to corrupt an application program quickly using this
feature. Note: Search and replace can only be performed on an offline file.
There are two methods to access the Search and Replace feature: By selecting
Search → Find then clicking on the Replace button or by selecting Search →
Replace.
Below is an example of the search utility using the replace function.
Each time the Find Next button is pressed, the system will highlight the next
occurrence, the user can then select replace to perform the operation. This can
be done on an individual basis for each occurrence of the search criteria, or if
there are many instances to be changed choosing the “replace all” triggers the
system to scroll and change all occurrences of the search.

Searching and Cross Reference
Cross-Reference
Another method of locating items in a project is to use the cross reference
function. The Cross-Reference may be accessed through the menu or by the
short cut CTRL-E. The function may be used by:
• Accessing the cross reference with no tag selected and then choosing a
tag from the combo box
• With a tag selected in a window, right click and select cross reference or
by using the short cut. The cross reference for the tag will be generated.
The cross reference may be filtered (Show) or sorted, you may also change the
scope of the report. Typically you will only be interested in locations that are
destructive (written to or controlled), use the Show filter to display only
destructive entries.
After using the cross reference to navigate to a tag, the window is still open; if
you need to perform an additional cross reference, use the Window menu to
access the screen or Ctrl-Tab.
Your Turn
The instructor will provide you with a project to use, and a list of tag names to
locate in it.
Find all the destructive references to the tags on the list provided.
