How to generate PLC drawing in solidworks electrical?

Hi, 

In solidworks electrical, I added a plc to a line diagram and connected the plc to a limit switch. I reserved the cable and connected the ports using detailed cabling. But when I generate the plc drawing. I was expecting the drawing to contain my detailed cable. But instead it is empty with only the plc in it. I wonder what I am missing.
