10. If you have chosen Indexed Address Load Mode, you can press [F6] Edit Index to

the load operation.
Editing the Address Index (Indexed Mode)
When you have selected Indexed mode to import a library file, you can offset addresses
so that addresses in the imported rungs do not conflict with addresses present in the
ladder program. For instance, you may have a series of addresses in the library that
begin at T4:0. If the base program also contains addresses at T4:0, you may want to
offset the addresses in the library to accommodate the addresses in the base program. If
your library addresses are T4:0 - T4:10, and your base program contains addresses T4:0
- T4:5, you could offset the library addresses to T4:6 - T4:16. Then the addresses no
longer conflict.
Addresses which were assigned as local in the original program will automatically be
assigned as local to the current ladder file. If a local address in the library conflicts
with a global address in the program, the next available data file number is used to
create a file of the same type for the incoming address.
To edit address indices:
1. Press [F6] Edit Index from the Import Configuration menu. The Edit Address
Info screen appears. (Directions you need to get to this point are given above in
the section on Loading a Saved Block of Rungs .)
