2 XBTN on one Twido PLC

We use one Twido-PLC controlling a machine. We use XBTN as the operator-Display. This machine has a very long dryer and it is fueled by a gasifier from a very far distance. "Setting temperature" at the dryer is changing all the time according to the machine speed. Operator in the gasifier room need to know the "needed / setting temperature" and the "actual temperature" in order to adjust the gasifier output to the machine. How to display it?
