procedures, refer to the "How to read the CPU diagnostic buffer (Page 66)" section
Save the diagnostics buffer to a HEX file and to a TXT file!
the cause, for example:
– I/O error
– Synchronization error with an H-CPU
mode, save the diagnostic buffer of the relevant module and the associated bus interface
module (for example, CP 443-5).
(default: [Installation path]\Siemens\WinCC\Diagnostics).
You can back up the diagnostic files using the shortcut menu command Save to >
Compressed (zipped) Folder.
Note
Once the diagnostic files are backed up (not in diagnostic folder), you can delete the
content of the diagnostic folder. In this way, you avoid keeping old information in the new
diagnostic files.
If the same error occurs the next time you start WinCC, make an additional backup to help
the experts. Only a few messages will need to be analyzed in this backup.
