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
● From the cross-references, you can jump directly to the point of use of operands and
● During a program test or when troubleshooting, you are notified about which memory
