The comms Debug tab

The communications debug 'panel' is accessed by clicking the debug mode button bottom right.

The same button is used to get back to the register view. Note the 'T' button, which takes you to the Trainer screen

The debug screen sports 4 controls, Pause, Stop Tracking and Clear, with a timestamp display option. Timestamp is minutes:seconds and milliseconds.

While in register view, the comms debug view gathers trace data in the backgound. Below is an example of the comms you will see, here the simulator is trying to request/transmit unsolicited in the Allen-Bradley mode.
