DiscreteInputs adress wrong?

[Tom54497]

Adding the first discrete input it will get an address 10001 in the adapter settings as expected. But at the objects tree I will end up with 10014. Adding a second discrete input it will get an address 10002 in the adapter settings as expected. But at the objects tree I will end up with 10013.

Is that correct? It is just the other way round like holding registers end up in the objects tree! Means 30001 always is equivalent in settings and objects tree!
