Diagnostics
5.3 Diagnostics via Startdrive
This is how you diagnose typical topology errors
Three typical error cases are shown in the following:
First error case: DRIVE-CLiQ connection on the interface of a DO not inserted
1. Position the cursor over the interface highlighted in red on the first drive object (in this
case, the Control Unit).
A tooltip is displayed. To open the tooltip, click on the black triangle.
The tooltip shows the target connection compared with the currently available connection
and a brief description of the error. For example, there is no connection between interface
X103 of the Control Unit and interface X500 of the TM31.
2. Display the tooltip of the partner port marked red on the TM31. The error describes that
there is no connection at interface X500 of the TM31.
Note
If several interface are marked red, starting from the left and moving to the right, check all
error descriptions using the tooltips.
3. Check the DRIVE-CLiQ wiring on the real hardware. Insert the connection according to
the target topology.
4. Acknowledge the active errors in the message view.
The interfaces in the device view are shown in blue if the actual and target topology
match after the error has been corrected and the message acknowledged.
Second error case: Two interfaces interchanged for a DRIVE-CLiQ connection
1. Check the interface marked in red on the first drive object.
Typically, it is displayed that no connection should be inserted. However, in the actual
topology, there is a connection to a different interface. For example, a connection exists
from X101 to X200 of the Line Module, which is not configured.
2. Check the partner interface marked in red of the other drive object, in this case the Line
Module.
It is displayed that a connection should exist to X100 – however it goes to X101. When
connecting up, the two interfaces were interchanged.
3. Change over the connection at the first drive object from X101 to X100. This means that
the actual and target topology are identical, and the interfaces are shown in blue.
Note
When switching over connections in the online mode, several errors can be briefly
displayed, as certain objects can no longer be accessed. You only see the updated view
without any errors once the target topology has been completely wired and is accessible.
