XBee S2 and Arduino Uno

I’m new with Arduino and Xbee and I would be happy to know, how to get communication between X-CTU (Laptop) and an XBee S2 mounted on a wireless shield for Arduino Uno. Normally I have to remove the Arduino from socket, but are there any possibilities to get communication without removing the Arduino.

Regards and thank you very much

How are you connecting the XBee to the PC? Is the one connected to the PC going thru the Arduino?
