You can use this menu command to call up the reference data and to set the filters
before the reference data are displayed. If a program is very large, you can use
filters to limit the quantity of data to be displayed. This enables you to obtain the
information you require more quickly.

Messages are identified by a number which is unique throughout a project. Each
individual S7 program is assigned a number range within the whole range of
numbers available (1 – 2097151). If you copy a program, the new program must be
assigned a new number range.

The menu command Edit 

opens the dialog box in which you can select the number range for the new
program. The dialog box shows the number ranges which have already been
allocated and the respective programs to which they have been assigned. These
ranges cannot be used again. The dialog box is also displayed when you copy or
insert programs into a project and the number ranges overlap.

If you want to change the number range for a program, proceed as follows:

1. Copy the program.

2. Insert the program in the project again and assign it a new number range.

Background: A number range can only be assigned to a program containing no
messages. If messages are already present, you must copy the program and
assign it a new number range.

Tip: To avoid having to renumber a program later on, you should check the
number range first before you create any messages.

Menu command File 

 Messages, see Chapter 12 (Printing).
