Manual VIPA CPU 21x Chapter 4 Deployment of the CPU 21x-2BT10 with TCP/IP
HB103E - Rev. 05/45 4-41
The CP 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 CP 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.
Note!
Please always control the preconditions for an operative communication
using the check at the beginning of this chapter.
For the aimed diagnostic deployment the following approach is convenient:
• Start diagnostic.
• Open the dialog for the online connection with
, enter connection
parameters and establish the online connection with [OK].
• Identify the CP and check the recent state of the CP via module status.
• Check the connections for particularities like:
- Connection status
- Receive status
- Send status
• Control and evaluate the diagnostic buffer of the CP via diagnostic
buffer.
• As needed, alter project engineering res. programming and restart
diagnostic.
