Line Sensor

Hello,

I have some problem with the Line sensor (smart component) in Robot studio.

The cell I working on in robot studio contains serval "stations" one of them is a measuring station. In this station I use line sensor for three sensors. Which is in this case will be three line sensors.
At the beginning I have created three signal of the kind Digital input one for each line sensor.
This digital outputs "names" used in the Rapid code. 
I read in other discuss that line sensor will work if the Sensorout on the linesonr is connected to the output on the smartcomonent.

This is the way I have done so far:
1. I started to create three digtial outputs under I/O controller with different unit mapping related to an unit i created.These ones I used in rapid code.
2. Then I created the three line sensors under same smartcomponent.
3. Adding a I/O singals.
4. Adding a I/O connections.
5. Then I connected the Smartcomponent Onput to the line sensors "Active".
6. Now tried to see if the line sensor worked during simulation without the system which it did. 
Problem is that the system don't response during the simulation during when the system i active.

Under the I/O controller when filtered the smart compontents of line senors respond but when the system i selected instead there is no respons of a signal of the outputs.
The system even don't wan't to start either as meantion before.
I have tried to use digital input  instead. With DI the system will start the program but I have to controll the signals manually in the I/O controller.


Does any one have a clue to make i work?
