Hi @Thomas Nuesslein,

It was possible to do this in earlier versions, but not in IFSAPP10. 

In IFSAPP9 and earlier, a connect reader could read and process only one message at a time. Therefore the poll time was necessary. However this was considered inefficient and therefore, redesigned in IFSAPP10. In IFSAPP10, the connect readers fire twice every minute and read and process all the messages at once. 

Due to this design, poll time for connect readers cannot be adjusted.

Hope this helps!
