Detecting and correcting a topology error
Operationally ready drive objects (DOs) are displayed with a green checkmark in online mode.
Erroneous port assignments are marked in red.
Figure 6-2 Example: topology error for DRIVE-CLiQ connections
The following describes 3 error scenarios, which illustrate the detection and elimination of
topology errors.
Fault scenario 1: DRIVE-CLiQ connection on the interface of a DO not inserted
1. Position the cursor over the interface that is marked in red on the first drive object (in this
case: Control Unit).
A tooltip is displayed.
2. 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, the connection of the interface X103 of the
CU is not plugged into the interface X500 of the TM31.
3. 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.
