Cross reference to show usage
The Inspector window displays cross-reference information about how a selected object is
used throughout the complete project, such as the user program, the CPU and any HMI
devices. The "Cross-reference" tab displays the instances where a selected object is being
used and the other objects using it. The Inspector window also includes blocks which are
only available online in the cross-references. To display the cross-references, select the
"Show cross-references" command. (In the Project view, find the cross references in the
"Tools" menu.)
Note
You do not have to close the editor to see the cross
-reference information.
You can sort the entries in the cross-reference. The cross-reference list provides an
overview of the use of memory addresses and tags within the user program.
● When creating and changing a program, you retain an overview of the operands, tags
and block calls you have used.
● From the cross-references, you can jump directly to the point of use of operands and
tags.
● During a program test or when troubleshooting, you are notified about which memory
location is being processed by which command in which block, which tag is being used in
which screen, and which block is called by which other block.
