Cross reference table

Note
You must compile your program in order to view the cross reference table.
Use the cross reference table when you want to know whether a symbolic name or memory
assignment is already in use in your program, and where it is used. The cross reference
table identifies all operands used in the program, and identifies the POU, network or line
location, and instruction context of the operand each time it is used. Double-clicking an
element in the cross-reference table displays that part of your POU.
Element refers to the operands used in your program. You can use the toggle button
toggle between symbolic and absolute addressing to change the representation of all
operands.
● Block refers to the POU where the operand is used.
● Location refers to the line or network where the operand is used.
● Context refers to the program instruction where the operand is used.
