1. Cross reference table

1.1. Explanation

You must compile the program to view the cross reference table.

To understand whether a software component has been used in the program and where it is used, use a cross reference table. The cross reference table identifies all software components used in the program and specifies their specific usage locations and instructions.

Double clicking on an item in the cross reference table will navigate the program editor to the corresponding location.

Table Properties	Description
Software component	The software component used by the program.
POU	The program that uses this software component.
Location	Where is the software component used by the program.
Instructions	Instructions for using this software component.
