Assigning CPU-Oriented Messsage Numbers
Multi-User Editing Projects
• Programs can be copied within a project to interprojects without a change of
message number.
• The message number will change when you copy single blocks. Here you need
to recompile the block in order to implement the changed message number in
the program.
Copying a Program with Project-Oriented Message Number Assignment into a
Project with CPU-Oriented Message Number Assignment
• To copy a program whose message numbers were assigned project oriented to
another project that contains a program whose message numbers were
assigned CPU oriented, select the required program, call menu command File >
Save As... and enable the "Reorganize" check box in the pop-up dialog box.
• Message attributes are assigned by default when copying. Inconsistent
assignments are displayed in a pop-up dialog box. In this box you can choose
your assignment.
Copying a Program with CPU-Oriented Message Number Assignment into a
Project with Project-Oriented Message Number Assignment
You can only copy single FBs with messages.
Caution
The assignment of message numbers in the program of a project must be
uniform!
When you copy a message-type block that contains a cross-reference to a text
library to another program, you must include the corresponding text libraries or
create another text library of the same name, or modify the cross-reference in the
message text.
