a KNX Group Address can only appear once in the Comfort to KNX and KNX to Comfort Tables. Hence if 1/1/1 is mapped to Line Cut state in Comfort to KNX, then you will not be able to enter 1/1/1 again in the KNX to Comfort table mapped to a counter. You will see that the drop-down list to select group addresses prevents you from selecting addresses that are already in the tables.

I believe that allowing group addesses "belonging" to Comfort for security conditions may not be to difficult to implement so that would be a better solution

On the other question, when a Counter's value changes that change is sent to the KNX group address
For example say 0/0/1 is a 1-bit Group address (EIS1) is mapped to Counter 10
If Counter 10's value is changed to 255, then a telegram to 0/0/1 is sent with value ON.
Changing counters from Comfort does not activate a Counter Response but changing counters from KNX will activate the Counter Response for that counter
