16.9 Configuring the 'Reporting of System Errors'
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 385
16.9.5 Generating Blocks for Reporting System Errors
After you have completed your settings for reporting system errors, you can generate the required
blocks (FB with assigned instance DB and one or more global DB(s) and an FC, depending on the
setting even OBs that do not yet exist). To do this, click on the "Generate" button in the "Report
System Errors" dialog box.
The following blocks are generated:
• Diagnostic FB (default: FB49)
• Instance DB for the diagnostic FB (default: DB49)
• Shared DB (default: shared DB50)
• FC (default: FC49)
• Error OBs (if you have selected this option in the "OB Configuration" dialog box)
• Optional user block called by the diagnostic FB
FBs and instance DBs are called by OBs, FCs and global DBs are used by SFM-FB.
Note
If you want to reorganize your project with the menu command File > Save As... and the "With
Reorganization" option, remember that the diagnostic blocks need to be regenerated in 'report system
error'. Since the reorganization of a project with diagnostic blocks is very slow, it is advisable to delete
the diagnostic blocks first and then generate them again.
