Displaying cross references

You can display all the operands used in the PLC user project and their use in the list of
cross references.
This list indicates in which networks an input, output, bit memory etc. is used.
The list of cross references contains the following information:
● Block
● Address in the network
● Context (command ID)
Symbolic and absolute address
You can choose between specification in absolute or symbolic address.
Elements for which there are no symbolic identifiers are automatically displayed with
absolute identifiers.
Opening program blocks in the ladder diagram
From the cross references, you have the option of going directly to the location in the
program where the operand is used. The corresponding block is opened in window 1 or 2
and the cursor is set to the corresponding element.
Searching

detail:
