Cause:
The topology comparison has found a component in the actual topology which is not specified in the target topology. The alarm value includes the component number and connection number of the component with which the additional component is connected.
Alarm value (r2124, interpret hexadecimal):
ddccbbaa hex:
cc = connection number
bb = component class of the additional component
aa = component number
Note:
- component class and connection number are described in F01375.
- components that are connected to this additional component are not operational.


Remedy:
Adapting the topologies:
- remove the additional component in the actual topology.
- download the target topology that matches the actual topology (commissioning software).
Note:
Under "Topology --> Topology view" the commissioning software offers improved diagnostics capability (e.g. setpoint/actual value comparison).
