The PROFINET IO controller has a diagnostic buffer. This has the
architecture of a ring memory and may store up to 100 diagnostic
messages. The NCM diagnostic allows you to monitor and evaluate
the diagnostic messages via the diagnostic object Diagnostic buffer.
Via a double click on a diagnostic message the NCM diagnostic
shows further information.
You execute a diagnostic by clicking on a diagnostic object in the
navigation area. More functions are available via the menu and the
symbol bar.
For the aimed diagnostic deployment the following approach is con-
venient:
1. Start diagnostic.
2.
Open the dialog for the online connection with enter connec-
tion parameters and establish the online connection with [OK].
3. Identify the PROFINET IO controller and check the recent state
of the PROFINET IO controller via module status.
4. Check the connections for particularities like:
n Connection status
n Receive status
n Send status
5. Control and evaluate the diagnostic buffer of the PROFINET IO
controller via ‘diagnostic buffer’ .
6. As needed, alter project engineering res. programming and
restart diagnostic.
