4.4 Conflicts when copying blocks
Two different conflict types can occur during the copy and insert of program blocks:
● If several
blocks with the same block numbers exist in the program blocks folder, a message
is not displayed immediately. Because duplicate block numbers are flagged only during the
compilation,
compile your project after performing a copy in order to detect any conflicts early.
Figure 4-4 Error message when block numbers or addresses are used multiple times
If duplicate block numbers exist, proceed as follows:
– If
this involves one of the blocks of the basic program that you do not require (e.g. unused
axis DB, channel DB, FB or FC), you can delete it.
– If a user block has the same block number as a required basic program block, you must
change the number of the user block.
● The presence of duplicate symbolic block names is checked already during the copy action.
A message is issued if conflicts result because of existing symbolic names.
The dialog offers you the following ways of rectifying the conflict:
– You
can cancel the copy process, search for the duplicate blocks in the project tree and
delete them before you initiate the copy process again. In this case, click in the "Cancel"
dialog box.
